Hello There, Guest!

eat your vitamins!
#1
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.

Vitamin D Found To Stimulate A Protein That Inhibits The Growth Of Breast Cancer Cells

general info on vitamin D and calcium absorbtion; warnings on too much calcium absorbtion and i.u. recommendations.
http://www.ncbi.nlm.nih.gov/pubmedhealth/PMH0003057/

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.

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.

Blood levels of 35-40 ng/ml appear to be best according to this analysis. However, 30-35 ng/ml appears to be best in this one. Earlier research found that 32 ng/ml was the minimum necessary to avoid vitamin D deficiency, so it doesn't make sense to me that the minimum necessary is also the optimum and I thus choose to believe in the 35-40 ng/ml target. It takes me 5000 IU/day to get there and I monitor it with Labcorp tests purchased through http://www.lef.org.

Labcorp's reference range (30-100 ng/ml) is absurd and irresponsible. Unlike their other tests where they derived the ranges from actual data, the 100 ng/ml upper limit was pulled out of thin air. In the past they would cite this paper as justification for the range, and the paper says "I have arbitrarily set the toxic level at 250 nmol (100 μg/L)".

Interesting, I may double up on my vitamin D then. Couldn't hurt at least.

Vitamin D is actually not even a vitamin…

…It’s a steroid hormone, mistakenly named as a vitamin.

…Needless to say that if your serum vitamin D levels are too low, more than 1,000 bodily functions are also somewhat impaired.

Several of these functions that vitamin D regulates are linked to the endocrine system, thus not getting adequate amounts of “the bone vitamin”, should in theory reduce testosterone levels.

And if we take a look at the most recent studies, we can see that it’s not only a theory:

a) This study found out that men with sufficient vitamin D levels had significantly higher testosterone levels and lower SHBG count, than men who had insufficient amounts of the vitamin (or hormone) in their blood serum.

Association of vitamin D status with serum androgen levels in men.
http://www.ncbi.nlm.nih.gov/pubmed/20050857

b) This study found out that when healthy male participants take 3332 IU’s of vitamin D daily for a year, they end up having 25.2% more testosterone on average when compared to placebo.

Effect of vitamin D supplementation on testosterone levels in men.
http://www.ncbi.nlm.nih.gov/pubmed/21154195

c) This study found out that older men who supplement with vitamin D, are less likely to have low testosterone levels than men who are not supplementing with the “bone vitamin”.

Additive benefit of higher testosterone levels and vitamin D plus calcium supplementation in regard to fall risk reduction among older men and women.
http://www.ncbi.nlm.nih.gov/pubmed/18351428


The optimal amount of vitamin D in the blood serum seems to be around 50-70 ng/dl. This can be quite easily achieved when supplementing daily with a low to normal dose of high quality vitamin D3 supplement (this is my recommendation) or by spending few hours in the sun each day. Best if you do both.

NOTE: You should avoid the D2 form of the vitamin, it’s cheaply made and the chemical process of manufacturing it is questionable. It’s also not nearly as good in terms of bio-availibity as the D3 form is.


CONCLUSION


Vitamin D is simply a testosterone booster that’s backed up by some extremely solid peer-reviewed research.

It’s also known for its ability to increase lifespan, it improves cardiovascular health, and it even maintains bone health when taken along with calcium and vitamin K2.

It makes me lose faith in humanity to see this recommendation all over the place. (I should note that I'm not mad at you Lotus - that would be shooting the messenger.) No one ever cites any evidence to back it up. Well, LEF did provide a bunch of footnotes in one of their magazine's articles, but when I looked up the papers, not a single one supported going over 50 ng/ml. (Notice how the bro-science website didn't even get the units right. They used the ones you'd use for total testosterone.)

Both. The ratio would depend on how much 5-AR your body has and how much 5-AR inhibitor you're taking.

Vitamin D does not seem to affect the level of 5-AR, but it increases aromatase in bone cancer, ovarian cancer, and prostate cancer cells, and decreases aromatase in breast cancer cells and fat cells. No effect on aromatase in healthy ovarian cells. This could be why D is so protective against breast cancer but doesn't seem to affect prostate cancer risk at all. The aromatase elevation could cancel out D's anti-cancer effects.

Vitamins are very essential for healthy skin as well as providing essential elements to body. But some of the vitamins can be harmful to the body.
