Too Much Vitamin D Side Effects

Taking too much vitamin D can lead to certain side effects. In fact, any vitamin can cause problems if taken in extremely large doses. Too much vitamin D can cause some of the following problems:

● Vomiting
● Dehydration
● Constipation
● Irritability
● Pain in bones
● Appetite loss
● Anorexia
● Eye soreness
● Muscle pain and/or weakness
● Chronic fatigue

As you can see, some of these side effects are very similar to the symptoms of vitamin D deficiency.

For children, recommended dosage is 1000 International Units. For adults, it is from 400 International Units to 2000 International Units. The dosage will depend on various factors, like age, condition, sun exposure, diet, other medications used by a person, etc. Overdose is rare, and it usually occurs in people who take doses that are too high, without any supervision by their doctors. This is rare, but it can happen and it can lead to problems. You cannot overdose with vitamin D if you spend time in the sun. Your skin “knows” how much it needs. You can’t get too much vitamin D from foods, because the quantities found in foods are small; if you wanted to get enough vitamin D from these foods, you would have to eat extremely large amounts of animal meat, dairy products, or fish, which would certainly be unhealthy.

Vitamin D is very important for overall health. It takes part in several important processes that take place in the body, some of which are closely related to the immune system. Numerous researches have proven that vitamin D is helpful in preventing diabetes, multiple sclerosis, cardiovascular disease, rickets, osteoporosis, osteomalacia, and certain types of cancer. It is also used as a part of therapy in patients who suffer from these problems.

    My vitamin D level was just 5.7 iu
    My doctor started giving injection of 600000 iu per month. Taken two injections. Now my Vit D level is 77 iu against normal of 22-32. Is there any problem if Vit D is in excess and if so what is the remedy? Pl reply

    vegelite makes a vegan 400 mg. tablet. I have been taking 3000 units of the lanolin based soft gels from dales natural food for 10 months and my d- levels are still at 28. so I am switching to the vegan brand. I am very tired with muscle aches.just had blood work done and every thing else is fine. is there anything that blocks d-3 absorption ?

  3. marilyn says:

    my doc just started me on 50,000 units once a week . just done it one week but feel like I’m dragging and have headache. Don’t feel good after just taking one time. Adding Magnesium now. See if that helps

  4. Elizabeth says:

    I said I was on 5000 units but when I checked the bottle it is 50,000 units once per week. Would this much cause the itching I am having?

  5. Elizabeth says:

    I have been on 5000 units once a week for a month and I have started itching on my neck sides and back. I also have itching in my head and it is the worst. I wanted to know if it is coming from the Vitamin D. It feels like something is crawling on my skin and is very bad on my scalp.

  6. Judith says:

    I have been taking Vitamin D3 for a deficiency for the past year or so. First it was 1,000 IUs and when the level did go up significantly, the dosage was raised to 2,000 IUs. I’ve been having extreme pain in my right hip and finally thought that it might be related to taking the Vitamin D. When I stop it for a few weeks, the pain is almost gone. Also, just realized that the gas, bloating and weight gain that I’m experiencing when taking it regularly is probably being caused by the D supplement! I have a physical scheduled for next week and will talk to my Dr. about it. I can hardly go up my stairs because of the pain so I need to find out what’s going on.

  7. Dorothy says:

    Dr. has me on 10000 iux7 for 6 weeks. It is no wonder I feel the way I do. I was beginning to think something awful was wrong with me. By the sound of things after reading the above comments, it is the Vitamin D. Seeing my Dr. for follow-up this week, so hoepfully we will get this resolved. 70000 iu a week for a 105 lb woman is probably no so good. I wake up at night severely nauseous and it scares me. Always thought of myself as having a stomach made of steel!

  8. john says:

    I had a thyroid & parathyroid dectomy 38 years ago. Consequently i’ve been taking 50000 iu capsules daily the entire time without the side effects mentioned in most articles on the subject. The past 3 yrs my D levels shown in my blood tests is about 200. Consequently, I’m wondering does my surgery change the validity of the information provided in these articles.

    I have been on d3 for four months. Started having wheezing, coughing, constipation, confusion, fatigue, muscle pain, major dehydration. The other day after I took my dose which was up to 6000 units a day something told me that I’m allergic to it. Looked it up on line and I’m very allergic to wool most d3 is derived from lanolin from sheep. I’ve been off it for three days already feeling a lot better. It can take up to four months to entirely leave the system as it is fat soluble and remains in the tissues a while. You can get d3 made from coconut oil or palm oil which will not have that effect. I plan on finding it and buying some.

    Hope this helps some of you.

  11. Melissa says:

    I have fibromyalgia, osteoporosis, & chronic fatigue, I am inside all day at my job, and usually busy cleaning my house on my weekends off, I don’t eat much red meat, so my intake of vit D is almost obsolete, my pcp tested me and of course my vit D. Levels were very low, so my PCP put me on Vit D, 20’000 mg, but within 2 weeks or so, I started feeling nauseous, loss of appetite, tight chested, extremely achy body, persistent thirst, and oddly enough, a feeling of doom, and another symptom appeared, I developed a minty taste in my mouth, that would come and go, but 2 weeks ago I discontinued the vit D AMA, and within a week, I felt much better and all but the minty taste have disappeared.

  12. Angela says:

    I am a 52 yr old female and pre-menopausal, my Dr suggested I take Caltrate with D, after taking 2 weeks every joint, bone in my body hurt. She advised me to stop. I have had my Vit D levels check and all okay. Tried to take D3 by itself and same symptoms returned. She also suggested to take Centrum Silver after 2 weeks of taking this multi vitamin same symptoms again. Not sure what rheumatoid arthritis feels like but I swear my body hurt so bad I could barely move. I am a very active person and it was making me not want to move due to pain. Stopped the Centrum Silver. Started taking Dr Whitaker’s Forward Nutrition multi vitamin packets with everything in them including Vitamin D. Here we go again after 2 weeks can barely get out of bed. I know I need vitamins and minerals for good health but trying to find someone to shed some light on why I believe Vitamin D is causing these serious side effects. Can someone please help.

  13. Barb says:


    I stay away from Doctors! PERIOD. Unless I have a disease, then I go to a specialist trained to tease apart what is going on.

    I have had joint sensitivities for years. Knee surgeries and the like, therefore a fair amount of arthritis, as a result. Starting into menopause, my hands went stiff, not mild, severe,,,,,, my lower back and legs, could hardly work, and my feet were a mess, it hurt to walk. I was taking Vitamin D for a while, 2000iu, with my routine daily vitamin regime, I hike all the time as I have 4 dogs to get out, and its been a lot of debilitating pain to overcome daily, long story short, I just upped my Vitamin D intake to 4000iu, and I feel fantastic, have not been so aware, pain free and back to running. Wow!

    I would have a problem with being prescribed such a high does @ 50,000 iu of Vitamin D, sounds toxic and gives the symptoms you are trying to get rid of= overdose. Just be moderate in raise and lower moderately. I approach everything in life with MODERATION. Good luck all.

  14. Kellie says:

    Ash27 I would make sure that u keep after the doctors there were so many different things that my gyno thought it could be and at least she took the time to try to work with me to get to the bottom of this issue. My job requires me to stand long hours also I’m self employed so if I was really sore the leg aches and hadn’t had a great sleep the night b4 I’d sometimes have to cancel clients which meant I didn’t get paid. Like I stated b4 it’s taken me almost 5yrs to get to the bottom of what’s been going on with my body so stay on top of your docs to try to figure it out. All the best Ash27. 😉

  15. Kellie says:

    To Ash27, I will tell you Ive had the same symptoms as you are describing going on 5yrs now. I went to my GP who after a year sent me to an orthopedic surgeon, who after running numerous test told me it’s gynecological, so after a year seeing her she assumed I had endometreousis, after being placed in numerous medication and none seemed to really help, she did a scope and I’ve now found out I have varicose veins. I’m wondering does the pain seem worse before your period and then seem to taper off coming on the end of your cycle? Also I found I was vitamin D deficient so I google vitamin D and thought wow thats it that’s the problem but my gynecologist said most ppl are deficient especially living on the east coast (Canada). I had found out about the deficiency b4 my scope. I had also been sent to two differnt nerve doctors to have a nerve conduction test done, one of the doctors told me theres nothing wrong! The other said I had maralga parathetic (not sure if i spelled that right) which now finding out i have the varicose veins On the inside of my pelvis that Diagnosis seems far fetched Anyway wishing you luck. I really had to fight the doctors cause I know at times they thought it was all in my head

  16. Frank says:

    Started taking vit d3 3 weeks ago (I have crohns disease ) , my knees and shoulders have been painfull since starting with it , an ideas ?

  17. ash27 says:

    Im 22 yrs old and have recently been xperiencing excruciating pain in my thighs, mainly inner thighs and the back of it. Also tight squeezing pain in between my legs (pelvic area) I feel that its my bones! Docs advised a blood test for vitamin c and d. Due course. Eithr way, has anyn actualy xperiencd pains in the buttock, in between legs and upper thighs? Really worried! 🙁

    I mean I cant stand for lengthly times or do daily activity! Thats how bad it is. Cant even sleep at times as the pain is constantly there!

  18. Rod says:

    My doctors gave me the dosage of 50 000 International Units. I only took the dose twice in a month. I had no side effects at all. I know that some people have side effects, but I was lucky not to have any of these. I did my own research on this, and I found that it is very hard to overdose.

    Too Much Vitamin D Side Effects

    Some of the side effects you can experience if taking large doses are:

    ● Diarrhea
    ● Upset Stomach
    ● Nausea
    ● Vomiting
    ● Constipation

    Not all patients have side effects. Vitamin D toxicity is very unlikely. However, you must never use vitamin D supplements without talking to your doctor first. Your dosage will depend on how low your vitamin D levels are. Your doctor will have your blood analyzed to determine your vitamin D levels. Sometimes, people can be deficient, but without any symptoms. This means that the blood test is the only reliable method of diagnosing vitamin D deficiency.

  19. Sean says:

    I was diagnosed with this problem and my doctors gave me 50 000 International Units to take once a week. In the beginning, it was OK and I did not have any problems. However, in very short time (two weeks or so), I started having pain in muscles, diarrhea, cramps and flinching. I will go back to my regular check in five months, but right now, I am not very optimistic about it. I don’t feel any better; in fact, I get the impression that my condition is getting worse.

  20. John says:

    Is vitamin D overdose possible? Are there any possible side effects of vitamin D? Vitamin D seems to be quite safe, even if it is taken in large doses. Toxicity and overdose are very rare. However, this can happen to anyone, so let us learn more about possible side effects of too much vitamin D.

    ● My condition was quite bad. I have been ill for more than ten years! I was vulnerable to all kinds of infections, especially flu. Finally, I was diagnosed with vitamin D deficiency, and my therapy included 6 000 International Units for more than a year. I have to say that I feel great and I haven’t experienced any side effects of vitamin D supplements. My doctors also gave me magnesium supplements and vitamin C. My overall health is surprisingly good! I will keep taking these supplements for the rest of my life.

  21. Donald Sarty says:

    I’ve been chronically ill since 1998 with 3-4 major fuls/virus yearly, never had any uptime to get better, started taking 6,000 IU of Vitamin D the last 16 months, i’m 50 years old, I have never felt better in my life also taking multivitamins and 3000mg of vitamin C and 300mg Magnesium, my hair is thicker/fuller my skin is softer and my energy level wayyy up, i have not been sick since 3 months after taking the vitamins

    More is better, not enough is bad, especially nowadays with all the radiation/ chemtrails, fluoride,chlorine and 1,000’s of other chemicals we consume daily.

    I never miss a day since 16 months

  22. dbs says:

    For those taking magnesium, I’ve been told that the best form is Magnesium glycinate, which is better absorbed. I use a brand called KAL which I got at my health food store, and a couple of places online.

    Also, with B12, it is best to use a sublingual tablet, which is also absorbed better than a pill.

    Just my 2 cents worth! 🙂

  23. mdonthego says:

    Why are so many people on vitamin D?

    I found that my count was way way down and started taking it. I experienced the very same effects listed above, pain in my left leg, joints, stiffness and muscle aches. What is going on?? There must be some good vitamin D supplements and some bad ones, how do we know the difference? Is it the brand name, where they are bought, prescription vs over the counter??

    The medical teams must provide an answer to this growing concern over Vitamin D.

  24. shakuntala jadhav says:

    My son is 4years 3 moths now. He had Vitamin D3 level 90ng/ml when he was 1 year 3months old.
    Now will it be same?
    how do i get to know?
    when he gets fever he has always temp between 104-104.5. Is this because od excess of D3?
    Plz Answer

  25. Zhelani Mazzur says:

    Did you go back to the dr? If so, what was your new vitamin d level? 50000iu everyday for 20 days is extreme.

    Be sure to keep that prescription bottle with the incorrect information on it. If you have already given it to the dr., please get it back.

    I’m not sure how negatively that much vitamin d will affect you.(

  26. Eve says:

    I am going thru menopause ( 47 Years Old) and Dr. wrote prescription for 50,000 u of vitamin D. on bottle said ” take one capsule by mouth every day” I have taken 20 tablets. and have gotten a phone call from Doctors office saying that prescription was incorrect. Tablet was for once a week.
    They want me in for blood tests in two weeks.

    I have had leg pains, sleepless nights, my heart felt like it was breaking out of my chest, I was also very constipated and dehydrated.

    I thought ok this is just menopause! and it suchs!
    Do I just wait out the two weeks and just call if symptoms get worse. or do I do something now?

  27. Mike says:

    I was diagnosed with extremely low vitamin D And my doctor prescribed it well 50,000 units per week.

    Within a few days I developed burning pain in my shoulder joints, arms ,chest, hips and legs.

    After two weeks I stopped taking the vitamin D, but now three weeks later the pains continue. From the comments I see on this forum I believe I should take magnesium and B 12. Any additional comments or advice gratefully appreciated.

  28. mellomike says:

    If you are experiencing pain in your bones while taking vitamin D3, this is a sign that the D3 is working. Your body is using calcium and vitamin D to repair your bones. Patience while you heal is key. You’re going to have good days and bad days. Gradually the good days will outnumber the bad days until you are totally healed. Depending on how long your were deficient, this process of healing will take longer. The healing process can take 3-6 months and depending on how bad your levels were, it may take even longer. Also take magnesium with your D3, this will improve absorption. You should also take these with meals as this will help with absorption too.

  29. shelle says:

    I started taking 50,000iu of vitamin d weekly, I felt nothing at first even though my doc said I will have more energy and awareness at first, I am now on the 3rd week and im having diarrhea daily, muscles aches, flinching, and cramp w/ gas. My doc said come back in 6 months to see if my deficiency is up to norm. I dont feel norm I feel worse, Is something wrong here?

  30. Christine says:

    recently diagnosed with Vitamin D level of 5.8…. have been put on the 50,000 units 3x a week for 2 months. Then I go back for the retest…. I am feeling queasy all the time… and suffering a lot of the side effects mentioned. Not sure if I should just suffer through and keep taking them… or complain to the doctor.

  31. Gary says:

    Quincy: Excellent point on the importance of mag when taking D3. In March I was taking D3 50,000iu/week and started to develop some wierd vibrations, twitching, started taking mag about a month ago, and starting to feel better. D3 can take 6 months to a year to recover and I ve read mag can take 6 month to replenish, so Im trying to hang in there. Good luck

  32. quincy says:

    This is primarily pointed to Mary, who posted on June 6, 2011:

    I have Hashimotos disease and was also prescribed 50000iu/once a week of vitamin D. I took the first pill before bed and was looking forward to waking up a new woman…instead I woke up with what I would describe as severe fibromyalgia pains and a vibrating feeling in my limbs and torso. My heart felt like it was ebating out of my chest, although my pulse was normal. I was also very constipated and dehydrated, which is not normal. I called my endo and no one called me back. I turned to the net to find answers and found nothing for my symptoms to do with the Vitamin D.

    I don’t know how I ran across the info, but I read that magnesium in the blood has to bind with vitamin D in order to activate the D. If a person is already low on Mag, what little they have in the blood is sucked out by the D. This will cause fibromyagia-like symptoms and a “vibrating” in the body. No kidding. Mag acts like a muscle relaxer…none in the blood can cause some serious issues. This is why milk of magnesia is a laxative..

    I went to an independent pharmacy and bought Magnesium. The thing about Mag is that you have to pick a good type in order for it to absorb well. If you look at any chain pharm store, like Walgreens, you will most likely ONLY find magnesium oxide. I asked the pharmacist WHY they only carry this when the oxide has a poor absorption rate. He said bc it is cheap to make and cheap to sell! OUCH!

    The Mag that I bought was Mag citrate bc it has a good rap for being well-absorbed. I took a higher than recommended dose for two days and suddenly, my symptoms went away. I did continue to have achy pain in my left breast.

    I went to a homeopathic doc and showed him what I was taking and he told me to get off of it, that it was D2, which is synthetic and is not the right type of D to be taking. He said shame on my endo for not giving me D3!

    Now, I am off all vitamins to give them a chance to clwar out of my body. I will start taking D3 soon and see how the experiment goes..Hope this helps..

  33. saintd says:

    I forgot to add that you would be better served to get vitamin D3 from the health food store than your doctor. get vitamin D3. Your doctor gives D2 that is not so good for you and costs way more as D3 which is what comes from the sun. By the way ,sun is converted to vitamin D3 in your cholesterol.

  34. saintd says:

    I have taken 50,000iu of vitamin D a day for 30 days,twice. I suffered no side effects what so ever. you should have a level of about 40-90 ng/ml. 90 being a treatment dose for a lot of things such as heart disease,diabetes,cancer,etc.77% of all cancers would not happen if your levels are between 40-70 ng/ml. naturalnews site all are easy reads that will expose your doctor for what he really is,a drug pusher. He will know nothing of what you will read on these web sites.It may not even be his fault as doctors are afraid to step outside the training they recieved in medical school.Most of that training was from drug companies that hate prevention.

    I am 64 and in great health even after having a stent put in back in 2005. I take no meds at all,not even aspirin.After testing I have settled on 5,000 iu a day. It is a simple thing to get tested with your normal blood tests at your yearly physical or whenever. If you think you are taking to much than you would be best served to take more as it is virtually impossible to overdose on the vitamin D. When testing MAKE your doctor order the test; 25 hydroxy vitamin d. the only other test is a;1 25 dehydroxy vitamin d test. You simple want the one without the 1 in front of it. The test with the one in front of it will come back false high by about 50%. I had both at the same time and mine from the doctor came back 60% higher than the one from grassrootshealth. If you are in poor health and suffer when you first try to raise your levels just tough it out and the bad side effects will go away. them bad symptoms are very common and natural changes your body goes through as it heals itself.

    The sun is the cure and it is free. It is that simple. Everything else costs you a arm and a leg so why would the medical people heal a cash cow such as yourself? Set yourself free from this group of thieves now.

  35. Harriett Sharp says:

    I have just been diagnosed at a Vitamin D level of 19,(by an interim physician) but have not yet visited with my regular doctor about this.

    Thank you, all of you, for your input. One thing the interim doctor has stressed to me is the importance of taking magnesium and Vitamin B12 — which I have been doing sporadically (when I remember to take it). As for the joint pain, one thing I have found of great relief is taking MSM along with my calcium. It is readily available OTC. I don’t have a recommended dosage as my doctor asks me “What is MSM?” So I just follow bottle directions and intermittently increase if pain level seems to warrant it. I also take zinc.

    It does seem counterproductive to prescribe medications with side effects of joint pain when a person is already experiencing joint pain.

    Isn’t that just adding fuel to the fire?

  36. Mary says:

    I have hypothyroidism and low vitamin d levels. Recently, I was put on 5,000iu vitamin d3 supplements. After a few days I noticed I started to gain a bit of weight. I carried on with the supplement and then the severe aches and pains started – this has been mainly in my hips, lower back, and legs. I was also getting a lot of stiffness. The pain was so severe that I’ve stopped taking the supplement. I’ve been trying to find answers as to why this has happened. If I go to my GP, he will only say that it’s all in my head.

    I’ve gained about 4lbs in 2 weeks, and I’m sure it’s the supplement. I’ve also had an increase in appetite where I wanted to keep eating – hence the weight gain.

    I don’t know what to do. I think I’ll just stick to taking Osteocare which gives 400iu of vitamin D3.

  37. nawla says:

    I have started on vitamin d 50000 ml a week and i saw a major difference from the day i took the first pill energy etc, However,I know i need it, because without it you can development a lot of problems like heart attacks, etc. But I have gained over 10 pounds since taking it.

    Please tell me if you have gained weight really need to know.

  38. Kristen says:

    @ Vicky: Grab the Dr. who gives you crap by the genitals, and say to them, “SINCE NONE OF YOU DR’S CAN SEEM TO FIX MY PROBLEM, I WANT TO TRY GETTING MY VITAMIN LEVELS UP! It’s MY BODY, and since you are very responsible, I’m calling malpractice.” Complain, however you want to, threaten legal action if they won’t listen to you the patient, and your symptoms. If nothing else, if they have you write your symptoms on a form while in the waiting room, put all the crazy symptoms, not at all like you have.

    They earn money from you, and it sounds like they are using you as a cash cow, or are just not listening to you. That’s not right. How can they diagnose you if they don’t listen to you.

    And don’t let them explain it away with theory. They had to be cut-throat to survive med-school.

  39. Honora says:

    My vitamin D level was low at 21.1. I’m taking 1,000 units of D-3 once a day. I am also very tired. I’m in my 60’s and very active. Run 3 miles a day. Could my skin be breaking out from the vitamin D?

  40. Honora says:

    After 6 months of taking Vitamin D I find that I have pimples on my face, which I never had before. I’m thinking it’s the Vitamin D.

  41. Vicky says:

    My vitamin D level is 3, and I have been very ill for three years. I just found out about this even though my low levels have been showing up in my blood tests. No doctor has talked to me about this low level. One doctor though started to treat me for Fibro. She told me that one vitamin D level of a different sort was cusing my body to not absorb the good vitamin D. She believes in the Marshal Protacall. What she told me was interesting, and I might agree with it. It talks about the two vitamin D’s and how the one it way too high, and the vitamin D that everyone is showing is low because of the other vitamin D level. Please check in to this Marshal Protacall theory and let me know what you all think of this. I am taking no vitamin D’s yet, as the doctors are now seeing my Vitamin D is at 3. At times I feel I am dying. Which is causing my doctors to roll their eyes at me. Three years of this, and I am tired of being sick, and don’t want to continue to live with all the illness. PS, the low vitamin D levels feel to me like the too high of vitamin D. Bones ache and have been told bones are thin. Have a neck rash too and sores on my tounge for over a year. Been to a rumatologist, he didn’t even take a blood test, told me to go to physical therapy. Sick of this.

  42. Donna Too says:

    My doctor has overdosed me on Vitamin. D. In July I tested 20 so she put me on 50,000 iu/wk. I was tested again in Oct. and it was 24 so she doubled the dose. 50,000 iu twice/wk. I was tested again in Feb. and it was 40. She told me to stay on the double dose. I experienced stomach problems, no appetite, no energy and then developed kidney stones. During the last month I was at the emergency room with chest pains and the Dr. there told me to take Prilosec for indigestion. Three weeks later I visited my Dr. and told her all the symptoms I was having and she gave me another prescription for allergies. Didn’t even mention Vitamin. D being the cause. My sister is the one that went on the internet and looked up the drugs I was on and discovered it was an overdoes of Vitamin. D. I’ve quit taking Vitamin. D and hope I can someday get back to feeling normal.

  43. Angie says:

    I was experiencing fatigue, feeling down and my hair had a lot of breakage.

    I thought it may be my thyroid. Before my doctor did blood test she told my to take 5,000 iu of Vitamin D a day. She did a blood test and found my thyroid was fine but my Vitamin D levels were low. She prescribed 50,000 units of Vitamin. D once a week for 12 weeks. My lower back started to hurt so bad I couldn’t move. I notice the pain began after I started the 5000 but got a whole lot worse once I took the 50,000. I called the nurse and she told me to stop taking the 50,000 and when my back gets better just to take 1,000 iu of Vitamin D a day. It has been almost 4 weeks since I STOPPED the regimen and my back still hurts. I read an article about taking magnesium with the Vitamin D, however, I am not even taking the stuff and my back hurts.

    Any suggestions of what’s going on ?

    Could i be really depleted in vitamin D or did the Vitamin D mess my back up?

  44. Sara says:

    My Vitamin D level in Oct was 25. I was told to make sure I take my 2nd Calcium w/D at dinner time (I was always forgetting). So after 5 months of faithfully taking it twice a day (plus extra D on occasion) and getting more sunshine, my levels only went up by 1 point. so my Dr put me on prescription Vitamin D of 50,000 IU once a week. It has helped with my aches and pains.

    Last night I took my 5th one, so been on it 5 weeks now, and today I do not feel good. In past weeks I felt real good for the weekend after taking it on a Friday night. So I am wondering, am I getting too much??? My stomach has been bothering me, have had a headache all day which makes me feel groggy.

    My allergies were bothering me this morning so I took a Loratadine. Maybe my headache is from allergies. I don’t know, so tired of all this. I also was diagnosed with a B12 Def of 128 last Oct. Took shots for 5 months and got retested and it is over 2000 now.

    If all of you above that are still having muscle aches & pains have not had your B12 checked as well, I encourage you to request that. It can cause the same type of aches & pains if you are deficient.

    I also have hypothyroidism and wonder if I have Hashimotos. I’ve been doing a lot of research on all this and they all seem to be connected.

    I have hypothyroidism and a vitamin D level of 27- rheumatologist put me on 50k once a week for 4 weeks. Last weekend I had back pains so bad could hardly move, after taking my pill the pain went away. Now I’m starting to get the pain again- I’m going to make an soot because I don’t feel right. Anyone else having this back pain?

  46. Mary says:

    Was put on 50,000 units per day for 8 days. About two weeks after finishing the vitamin D dosage, I began to become anxious and depressed. Because Vitamin D is stored in our fatty tissue it took a while for it to go away. I read on the internet that depression can result from too much vitamin D.

  47. sandra says:

    Have level 13 Vitamin D. PA treated with 2000 units of D but feet and legs swelled. Found that Veralan, a channel blocker for blood pressure, interacted with the Vitamin D. Will look for another source.Just passing along in case some else had a reaction.

  48. nicole petersen says:

    Im on 50000IUs a week. Ive been on it for 6 months and im miserable! severe pain in arms and back. Chronic fatigue. Im not sure this is helping.

  49. Bubbles says:

    My doctor had me on 50,000 units, 1 per week for 8 weeks. I took another blood test and it showed that I am still vitamin D dificency. Now my doctor have me on 2,000 units per day, I don’t know how long I have to take this. I will know when I go back to her in 3 weeks. I was having sever pains in my left arm and legs. The pain is almost gone, but I am having a lot of cramping in both of my hands. I just don’t understand all of this. Is anyone else having a lot of cramping in both of their hands?

  50. Cindy Kinney says:

    I have been on vit d 2000 a day for 6 mos. I have started having severe upper gi burping, heartburn and awful taste in mouth. Have osteoporosis and low blood vit D. Anyone else have this problem?

  51. Sally~ says:

    I had been going to Doctors for 11 yrs. and was misdiagnosed. I felt like I was a hypochondriac. Needless to say I changed Drs. 8 times. It wasnt until a year ago that they mentioned I could have vit. D deficiency. I did, my level was 13. I was eating everything healthy (salmon, cheese) and as for sun, I live in CA and live outside practically. I started losing my hair, my bones ached so much that I couldnt even carry a wallet let alone a purse. The worse pain was in my hips. I felt horrible that I couldnt enjoy my children and found myself moody, angry and depressed. The 50,000 ius once a week started to help but then I begin having a break out on my neck and chest which was painful too. My levels went back up and I was taken off the D however this winter I was put back on again. Do any of you have cancer? I hear that vit. D def. usually do.

  52. Claire says:

    I am in second month of taking 3000iu per day, m count was 37, doctor told me should be between 120 – 160. What is the normal rate? Also taking 6000 mg fish oil daily. Next month I have been told to go back to 1000iu Vit d daily, this seems to run in my family with two other sisters having same problem one of whom lives in Perth, can this be heireditory?

  53. Mark H. Goldberg says:

    You state that the recommended daily intake of Vitamin D is 2000 IU for adults and yet the USDA recommends 400 IU. Where are you getting your information?

  54. zakir hussain says:

    my vitamin d is 9.85 no/ml,please suggest me how much dose is recommended for me and what are side effects if taken more.

  55. Emma says:

    My VitD blood level was 19 so my endocrinologist put me on 50,000 units of VitD 1x wk. I just took my 2nd pill and have noticed that for the first time in 2 years I am almost free of the hip joint and leg pain which almost crippled me. I feel hopeful for the first time in years. If VitD is not helping you, I read that it could be the parathyroid. Please see an endocrinologist and ask questions. They are specially trained to figure this out.

  56. Dale Williams says:

    I have been on Vitamin D and wonder if anyone else is having an issue that I am. I now take 50,000 units of Vitamin D once each week. Since being on it, during oral xex I have discovered that my vaginal fluids are VERY bitter. I have never had such a problem. Is anyone else suffering from this problem. I have looked everywhere and can’t find anything that indicates that this may be an issue with the vitamin d. Please let me know if anyone else has noticed this or should I be searching for another reason for this annoying problem.

  57. Lynda Wilcox says:

    I have recently found that I am severely deficient in Vitamin D and was prescribed 2,000 units per day for the next six weeks with a follow-up lab at that point. 50,000 units sound excessive to me.

  58. John says:

    I was diagnosed with vitamin d deficiency, my blood work showed 20.0 ng/ml it should be 30-100. My RX is 50,000 units of D2 once a week for 12 weeks. Then 2 1,000 unit caps of D3 every day. I hav’nt started yet.

  59. Becky says:

    I just started taking Vitamin D, 50,000 units, once a week for 8 weeks because my blood level was at 20 and the doctor said it should be at 30. I am having gas and bloating everyday – Anybody else had this side effect? Does it taper off? I am uncomfortable!

  60. Valeria says:

    Hi Joanne;
    Have you tried combining magnesium with vitamin D? I received my blood tests back and I have 6, so I am sure I will be put on a high regimen of vitamin D. I was also put on celexa before and suffer from bone aches. Thanks to update us on the effects of magnesium.


  61. fred says:

    i was put on 5000u of vitamin d because lab results showed i was deficient. after taking only one tablet i experienced a lot of bone and muscle pain. two weeks later im still in pain even though i stopped taking it. im wondering is there anything i can do to ease the pain while i wait for it to run out of my system.

  62. Joanne says:

    Hi, all. I was put on 50,000 i.u.’s per week beginning in April until now. My doctor has reduced it to once per month. I have noticed more pain in my bones, especially my left arm! This wasn’t happening before the Vitamin D. I just read an articule that you need to supplement the vitamin D with magnesium! So, I’m going to try that and see what happens.

  63. Roxanne says:

    I was given a dose of 28000 units per wk..I was not told for how long, but I was told I am completely depeted. I was just going to ask at my next email appt for how long. I have been on it for almost 3 weeks. I will say, I was all the things all the gals above listed BEFORE the vit D…I have improved in a ridiculous manner. I am upset as the Dr.s had me on all kinds of pills (celexa, etc). All I needed was a vitamin…I would just have them monitor it through blood checks…

  64. CEM says:

    To repair the vitamin D deficiency indeed your physician will temporarily increase the dose for high levels for a while. The doctor will have you come back for a “total” vitamin D test.
    Recommended levels for this vitamin have changed from a total of 30 to maybe, 50 within the range of acceptable norms. I’m still trying to find a credible source to inform me of how much for how long; when and how frequently to retest and what a “maintenance” dose might be. Let’s all look!

  65. Johanna says:

    I am on my ninth week of my first course of 50,000 iu of Vitamin D also. When I first heard that was the dosage I was concerned, but after researching it I am less worried. My level was 12 and I will retest at the end of 12 weeks. I also am having joint, muscle pain and exhaustion although it seems to be somewhat better than before I started the treatment. I can understand your concern if you aren’t improved at all and also getting a lot of sun and the large dose. Have you seen a rheumatologist? Did your level go up at all after the first course?

  66. Reda says:

    I had to take 50,000iu every 2 weeks. What is the count of your Vitamin D? That sounds like too much to take in one week.

  67. Donna says:

    I am presently on my second 12 week round of Vitamin D @ 50,000iu per week. I am also concerned about the overdose issue. I am more concerned however, about why my vitamin D is staying so severly low. Even though I spend most of my days outside and get plently of sunshine, my legs, joints, etc. are killing me, I have cronic fatigue also. Just don’t know where to turn anymore. I believe that I need to have someone to closely look at what the issues might be.

  68. Me24 says:

    I’ve started taking a Vitamin D 50,000IU, but my doctor told me to take one tablet every 7days – and she only gave me 4 to start off with and then to come back to her for a follow-up doctors visit….so @Debbi – that sounds like a lot to take everyday – you may want to have that checked.

  69. Barbara DiPrima says:

    My Mother is 92 and her doctor has given her a prescription for 50,000IU once per week of Vitamin D. She already had osteporosis although not severe. After reading about overdosing, I am very concerned that this is way to much for someone of her advanced age. She has recently complained of halluinations and although she also has some dementia she appears more confused as well. She has been taking this (controlled in assisted living)for several months.

  70. debbi lavender says:
