Junk medical claims about vitamins are shouted from the rooftops of the internet, over and over. I can barely keep up with it. The claims about vitamin D seem to be trendy now. That means it’s time for vitamin D review – is it worth it, or is it a waste of your money?
Now, I don’t think vitamin D is worthless. It is an important micronutrient for human health, and if there’s a chronic deficiency, supplementation is necessary.
Proponents of megadoses of vitamins, called megavitamin therapy or orthomolecular medicine (pseudoscientific terms to sound like they are based on real science), seems to work on the unscientific belief that if a little helps, a whole boatload will help a lot more. Most of these ideas have been debunked and are considered quackery and fads.
I wanted to take a look at vitamin D, from it’s actual benefits to health to the possible dangers from supplementation.
