so here i wanted to make a thread for vitamins,their usage and doses and effects/ precautions/contraindications. i will start off with vitamin D.

vitamin d ,the 'sunshine' vitamin is only produced in sufficient qualities
"Caucasians and others with paler skin will hit an "equilibrium point" after about 20 minutes of exposure to UVB light, at which point vitamin D will no longer be produced. ..If you have darker skin, reaching this equilibrium point can take two to six times longer (or up to an hour or two), depending on your pigmentation."

it has also been found to reduce premature births by up to by half.

general info on vitamin D and calcium absorbtion; warnings on too much calcium absorbtion and i.u. recommendations.

so it would stand to reason,if you are taking calcium suppliments for your Pm to work better,than vitamin d is 'the assistant to the assistant' so to speak.

as i see it, the pros outweigh the cons, with this vitamin.
to note: recommended doses vary from website to website. please fee free to add to/comment regarding this thread

Vitamin D is pretty major. For many even more major than calcium, since their vitamin D tends to be the bottleneck to their calcium. I've seen recommendations from 1,000 iu to 10,000 iu. I think 2,000 iu is best though a little more doesn't hurt. Over 10,000 iu may reduce the benefits, and the TUI (recommended tolerable upper limit) is set at 4,000 iu presumably to provide a factor of safety. Though it doesn't actually become harmful until an order of magnitude higher than that daily for months on end; you'd have to blow several hundred dollars on most supplements to actually hurt yourself with unwanted calcium deposits. Going outside is also a good way to go and it helps your mood and eyesight too on top of the vitamin D.

Calcium is used not only for bones but also pretty much everything. It's some major stuff. And since how much calcium you actually get is limited by vitamin D, vitamin D is pretty major. Too much dietary calcium can even make calcium levels worse.
