Best vitamin D3, 5000 i.u invaluable against winter illnesses plus.

Posted by iHerb Customer on March 19 2018 | Verified Purchase

Vitamin D3 is naturally made by sunrays on your bare skin. In bathingsuit one can absorb as much as 20.000 i.u in half an hour. Unfortunately people with dark skins seem to have a barrier against the sunrays and absorb much less D3 than whiteskinned ones. Non western people who cover themselves up from head to toe, never get any benefits of the sun. That leaves Vitamin D3 in capsule form as an excellent supplement for at least the months with the R in them. Now we have D3, 5000 iu, our restistance against infectious diseases like influenza etc is decreased so much that one may not get it at all this winter or at least shorten the duration of it and make it less severe.
