Testosterone in men is waning. Especially after middle age, and stats are now showing that this is happening to not only more men than ever, but also measuring lower levels than ever before.
I blame this easily on all sorts of environmental/pollutant causes, essentially endocrine disruptors, a primary culprit likely being plastic exposure as a xenoestrogen.
We also know most people north of Georgia on the longitude line are under-exposed to sunlight on a chronic basis. This represents a huge number of people world-wide. And the sun being the best possible source of natural vitamin D production in the human body, this presents an obvious problem.
In an article in Clinical Endocrinology published January 2, 2012 revealed a pronounced relationship between a man’s vitamin D levels, and his level of testosterone. And I know a couple professional male body builders who use as much as 5000 iu daily of vitamin D3 in an effort to up their testosterone.
The jury is still out on how much vitamin D to get in daily. I’ve seen some people take minimal amounts and do just fine, and others take the 5000 iu daily and have it barely move their vitamin D levels when tested. It should also always be complimented with magnesium, such as the topical magnesium I promote and love, since the two work in a synergistic manner. My personal choice as a supplement would always be only D3, and I’ve taken 5000 iu on an every-other-day basis in the past, but I do not plan on taking that amount again (would do one thousand IU/day instead), but my preferred route of obtaining vitamin D above all else is of course to go tanning, focusing on the UV-B ray-type booths or beds (I prefer stand-up booths personally), where I can count on my body naturally producing maximum amounts, while having the built-in-stop mechanism that assures I can’t possibly “take” too much (I never allow myself to burn, and my exposure is calculated and prudent).
I can tell when my testosterone levels are off. I will also use maca added to my protein shake as a way to boost my endocrine balance, and it without exception adds to my vigor…and my libido. Two sure signs my testosterone levels are doing just fine.
