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:
● Pain in bones
● Appetite loss
● 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.
