Vitamin D Overdose Treatment

Vitamin D overdose is very rare. However, this can happen in cases when extremely large doses are used. We will tell you more about vitamin D overdose causes and treatment. Vitamin D overdose can be a result of using extremely high doses of vitamin D supplements. Patients who are severely deficient in vitamin D have to take doses as high as 50, 000 International Units (weekly, or twice a month). Of course, such doses are prescribed for a reason. If a person’s condition is serious, high doses have to be given. However, in such cases, patients are always supervised by their doctors. Vitamin D levels in blood are regularly measured, and once they go higher, the dosage will be adjusted and it will be lower. Still, there are people who are afraid of becoming deficient again, and they sometimes take larger doses than recommended, believing that vitamin D supplements won’t harm them. Anything can harm you if you use it in the wrong way! Keep in mind that you must not modify your dosage without consulting your doctor!

What Are the Symptoms of Vitamin D Overdose?

Vitamin D overdose is characterized by the following symptoms:

● Nausea
● Vomiting
● General weakness
● Diarrhea
● Dehydration (caused by severe vomiting and/or diarrhea)

These symptoms will likely lead to exhaustion and weight loss. Weakness, numbness and coordination problems may result from the symptoms mentioned above. Muscle pain can also occur, just like in people who are deficient in vitamin D. If you use large doses of vitamin D, and you experience any of the symptoms mentioned here, visit your doctor and ask him/her to modify your dose.

The best you can do to prevent vitamin D overdose is control vitamin D levels in blood. If you are severely deficient, your doctor will insist on checking your vitamin D levels regularly. Once your condition gets better, your dosage will be changed. You won’t have to take extremely large doses. Even though vitamin D supplements are considered safe and overdose is highly unlikely, keep in mind that it is possible and it can happen to anyone!

For people whose vitamin D levels are normal, daily recommendations are from 400 International Units to 600 International Units. However, according to some researches, even the dosage of 1000 International Units cannot harm you. Still, the dosage will depend on various factors. Only a medical professional can give you the right dosage, based on your vitamin D levels in blood. You should not use any supplements without having your vitamin D levels measured first.

Vitamin D Overdose Treatment

Vitamin D overdose can be treated, but you need to visit your doctor in time. This means, as soon as possible. Your doctor needs to be familiar with your condition and all other problems you have been through, so make sure to tell your doctor everything. Don’t forget to mention the symptoms you have. Some of the symptoms can be easily mistaken for some other health problems. You should not try to relieve any of these problems by taking other medications. Visit your doctor to see what is wrong.

People who experience vitamin D overdose are advised to stop taking the supplements for a while. Vitamin D is fat-soluble (not water-soluble), and your body can’t just eliminate it, like some other vitamins. When you stop using vitamin D supplements, your body will gradually get back to normal and you will stop having the symptoms.

As we said, daily recommendations go from 400 to 1000 International Units per day. If you are healthy and have normal vitamin D levels in blood, you can use vitamin D supplements, in accordance with daily recommendations.

    Reply to mkGreen jun 15, 2011: You may have problem with vitamin D because of diet high in fiber, vitamin D is fat solule and need fat to be aborbed and be useful.Taking vitamin D without taking magnesium is a disaster, without magnesium, you can have calcification, contipation, and water retention, you may gain weight not because of the fat but because of water retention. Try transdermal magnesium which is topical apply on your skin, and see the different. I had experienced all theese symptoms when I start vitamin D therapy. Now I know that it’s not the symptom of over dose vitamin D, just because I took it wrong way. Since taking vitamin D four years ago, I haven’t get sick a day, that’s really a miracle for me.

    my doctor says I have the lowest Vitamin D that he has ever seen (7.4) and prescribed 50k per week for 10 weeks; accidentally not paying attention to the “per week” I took one pill every day for 6 days; yesterday, I noticed what the bottle really said.

    I’ve researched the possible reactions and so far am only experiencing a soreness in my back, am drinking 64+ oz of water per day to try and flush out the kidneys: stopped taking the multivitamin+calcium and am staying out of the sun, but continued the BP/HCT, arthritis, GERD meds, plus the Lovaza, cinnamon, garlic and milk thistle.

    should I be in panic mode?
    go to the emergency room?
    do I need to stop any of the other meds/supplements?

    I’ll call the doctor Monday and inform him.

    any suggestions will be sincerely appreciated

    My doctor gave me 50 000 last week, when she found that my vitamin D level was 20. I started taking this dose twice a week. I am overweight, so I hope that I will also solve this problem during my vitamin D therapy. If that happens, I will definitely continue taking supplements. It is very difficult to live with this excessive weight, not to mention other symptoms of vitamin D deficiency.

    Vitamin D overdose is very unlikely, but it can happen. Patients who have to take very large doses are often worried about overdose. Let us see what some of our readers have to say about large doses of vitamin D.

    ● I was diagnosed with D deficiency and my doctors told me to take 50 000 a week. I have been using capsules, every day for two months, and after that time, I went back to have my vitamin D levels rechecked. They were good, actually! My vitamin D levels have increased and reached 85. Generally, my health is much better now and I hope it stays that way. I don’t have any problems with my immunity and I don’t get flu as often as I used to.

    Hi I have for about 4 months feeling tired, pain in hands, feet and raised veins, periods all over the place and genuinely feeling like i was going out of my mind. My family doctor told me it was all in my head and i had recently found out that it was hard to conceive a child. She went on to say I had problems with this and that was why my body was out of sinc. I then went to another doctor after a month of crying and feeling like my life was out of control. The other doctor sent me for loads of blood tests. I went to get my results and i had a vitamin d level of 19. I did not have any idea how important vitamin d level was. I was prescribed 20ooo units per tablet 4 times a day for 5 days. After 5 days felt human again but must admit a month later and even though life seems to be going back to normal i still feel not 100%. Reading this I feel this ia a long road not a short one.

    Vitamin D overdose is possible, but it is rare. You can do several things to avoid this. Control your levels of vitamin D regularly. If your vitamin D levels change, (go higher), your dosage will have to be modified. Remember, only your doctor can change your dosage! Do not do anything without your doctor’s knowledge!

    I didn’t like the idea of 50,000 per day. My count was 25iu. So I took two 5,000 capsules (total 10) 5 times a week for 2 months and then had another checkup. My count was 85. After that I take 5,000, 5 or 6 times a week and my count varies between 70 and 80. If I take 5,000 every day then the count gets up to 97. My health has improved and I don’t ever have to worry about getting colds or the flu and I am a teacher of elementary age kids.

  8. Gary says:

    I was 15ng also. Took 50,000 iu/week for 8 weeks. I now take 5,000/day and magnesium. Magnesium will generally provide you with softer stools, and Vit D and magnesium work together.

  9. mkgreen says:

    I was very low in Vitamin D (15) so doctor put me on 50000 of Vitamin D2 for 10 weeks. By week 8 and 9 I was so constipated – nothing I take relieves my distress. I have gained 10 lbs – went from a size 8 to 10 – I drink lots of water, have a very high fiber diet and exercise and walk. Anyone have any ideas – have stopped taking it for 4 weeks no difference.

    I’m 38 yrs old, and was DX w/Vitamin D deficiency of level 14. I had symptoms of fatigue, depression, waking up in the middle of the night, and inability to lose wt (despite exercise and diet) for the past 6 months. My doctor prescribed 3,000 IU of D/day. I noticed lower back pains 1 week after the TX, but have continued on. I appreciate all of your comments and feel hopeful. I pray this Tx will alleviate my problems.

    I am 53 years old. I had gastric bybass surgery at age 38. I stopped taking my “intrinsic factor” vitamin after 10 years- “it smelled”. I was exhausted all of the time! My feet and back were in constant pain. (GO TO A CHIROPRACTOR for this – NOT SURGERY!!) At my Nuerologist office .I could not walk a straight line, if I was standing and shut my eyes – – I would fall over, I had no ankle reflexes – NONE – I still have none, but the other symptoms have almost gone away.
    I had to INSIST on Vitamin levels! The Dr would only perform 2 Vitamin levels at a time. I ended up with EXTREMELY LOW B12 and my vitamin D test was listed at below 7< – The test did not register levels below 7. My nuerologist said I had "Subaccute, combined degeneration of the spinal cord" Due to lack of B12 and also Vitamin D.

  15. sidney shoemaker says:

    All my life I have been hammered by colds and I finally listened to my body and concluded and proved that any more than smaall amounts of vit. d poisoned tmy innume system. I took powdered protein made from milk which showed no vit. D on the label and it got me and I wondered why and then I concluded that they used milk that had Vit.d added to it. Any recomendations? I know that I am not typical, but what do you recomend?
    Thank you,

    I have just been diagnosed with low vit D. Mine was at lvl 10. I also have hypothroidism in which I cant take D with my pill because it would cancel my thyroid pill out. Be advised if you have hypo/hyper thyroid- get urself checked for your vit D. At the moment when I sit in a chair it is really hard to get up and when I do my bones ache. I am 47- I just started taking vit D and I hope my bones feel better soon 🙂 Gl to you all.

  17. JoAnne says:

    Mine was 7 before I took supplements – I had been to a neurologist who tested me for MS due to muscle pain and severe weakness. After spending $12,000 having an MRI, electromyogram and nerve conduction study. This was after going from doctor to doctor wondering why I couldn’t stand for very long. I was only 53 at the time. I felt like I’d aged prematurely. In the end, the only indicator found was my low level of Vitamin D. I did not have much hope for it but after 2 weeks, I felt some relief. In six weeks, more so. After 3 months, the weakness was gone and the feeling that I was going to collapse. I still have joint pain which is related to my ligaments and not so easily solved. But thank goodness my P.A. ran the tests. I would encourage anyone to stay the course. It might just be the problem. And I took mine in milligrams. I now take 2,000 units at day and my Vit D level is 46. Many of the symptoms listed here sound like statin problems as well so check with your doctor if your muscle pain or weakness remains.

  18. Brenda DeBord says:

    I was diagnosed with low vitamin D and was directed by two physicians to take 50,000 units once a week for over a year. I quit taking it on my own in July when I began to have muscle pain in my legs and severe itching on the bottom of my feet. Now my legs tingle, and the bones in my lets ache, it is difficult to sleep as it seems to be more painful when I lay down. I called my physician and was told that it is impossible to overdose on Vitamin D.
    I already have hypercalcemia and just don’t know how to deal with this problem. Just be careful of letting physicians give you too much of anything-there is consequences.

  19. Judy says:

    My doctor prescribed 50,000iu of Vitamin D and I too was concerned abut taking that amount. I also take it once a week for 4 weeks. My blood test level was 16. I am 63, weight gain, fatigue, and cramps in my feet, leg pain. Does anyone have results yet from taking these doses? Did it work and without side affects?

  20. Darlene says:

    I too, just tested for Vit D. I mentioned to my doctor about being tired all the time and then waking up at very early hours in the morning, unable to sleep. I also have muscle pain and weight gain. I just received my results – I tested at 11. Dr. ordered 50,000 IU for 1 wk x 2 months, then retest. I took my first green tablet I sure hope this helps me and all of you!

  21. GAYLE SPULNIAK says:

    My doctor just prescribed 50000 IU of Vitamin D twice a week. Just started the therapy today. He also wants me to take 2000 IU daily OTC, at the same time. Then in 8 weeks I’ll test again. I don’t know what my levels are, but I”m gonna find out!

  22. Kelli says:

    Hey, I am 45 About 4 months ago i was tested because i had every symptom of low vit D. My number was 8. My dr. put me on 50,000 iu per week. I was tested again last month and my number was 19. She upped the dose to 50,000 iu 2x’s per week. I also asked the Pharmasist if this seemed much, when i told him my number, he said “Oh no this is exactly what you need.” So he was my second opinion. I also have a friend, different dr, that has her on 50,000 per week, he number was 31. I am feeling the difference of the higher dose, more energy and not as much bone pain.

  23. Carmen says:

    That is very common. I did this last couple of years when mine was around 30. Last week it was 21. So my doctor prescribed me to take 50,000 two times per week. Then retest me in three months from now.We shall see what happens. If ok, then she wants me to take a daily supplement from over the counter. I am 55 yrs. old. FIfty pounds overweight. I did not know overweight was a symptom of low Vit. D.

  24. Martha says:

    My bloodtests last friday showed my level is 19 (comparable to yours) but he recommended taking 3.000 iu daily plus 1 tablespoon of what is called “Lýsi” here in Iceland (fishoil with RDA dosage of D-vitamin and A-vitamin) – this I will have to do to raise my levels gradually but it will take time – I´m in for second bloodtest in 6 months to see how I am doing building my level up to at least 50 iu but preferably my level should reach 70 iu.
    If I were you I would call for a second opinion!

  25. Bj Gray says:

    My Dr. prescribed 50,000iu of Vitamin D, and I’m almost afraid to take that amount. I am supposed to take it once a week for 4 weeks. Have you ever heard of that high of a dose? Is that safe? My blood test shows my level at 20, so it is very low. Thank you.
