How much vitamin D do we need?

Again and again we read how important vitamin D for our health. It’s a pity but in our latitudes the most people are equipped with vitamin D not enough. But too much you shouldn’t take too. It is worthwhile to consider the mode of action of vitamin closer.

Studies have shown that around 60 percent of Americans have a deficit of vitamin D. The reasons are: too little sunlight (vitamin D formation by UV radiation) and too low consumption of vitamin D-containing foods, such as broccoli, herring and mackerel. Especially winter in our latitudes lead to deficiencies of the so important vitamin D.

It’s becoming increasingly clear how important vitamin D for our health. Studies have shown that vitamin D not only, as assumed before, strengthens the teeth and bones but can prevent Rickets in children. Rather, now we know that vitamin D can also strengthen the immune system. About the importance for the prevention of cardiovascular disease and cancer, and type 2 diabetes mellitus one is still not quite sure, but here, too, growing evidence for a beneficial effect.

Experts recommend daily 2,000 IU of vitamin D.

Lately even have been published studies which indicate on correlation between vitamin D and depression or multiple sclerosis. But how much vitamin D you should take? And in which case supply of Vitamin D can be harmful? Here is lately observed a change in the recommendations about quantities and frequency of consumption. About 200 to 400 IU were given as a daily recommended. However many experts put the needs of today with 2,000 to 4,000 IU, what is much higher. Especially to older people are advised to take daily at least 800-2000 IU of vitamin D.

However, you shouldn’t blindly take vitamin D supplements. So people should avoid the possibility of having a disorder of calcium metabolism or parathyroid disease by taking a Vitamin D. On the other hand recent studies shown that even high doses of vitamin D were well tolerated by the subjects.
