Testosterone levels tied to Vit. D levels

http://winslowjenkins.com

Vitamin D. kind of a misnomer, as it is actually a hormone synthesized form cholesterol. T, D3, and cholesterol all clearly share the steroid skeleton. let me know if you don’t see it…
we get D3 in one of three ways: by exposure to sunshine, orally through food/supplementation, and absorbed through our skin. it is of great importance to us and has been positively correlated with numerous health benefits including slowing the cellular aging process. click here to see a list of relevant studies to this effect.
today i want to touch on the strong correlation between vitamin D levels and testosterone levels in men. essentially, low vitamin D levels correlate to low T levels and vice-versa, per the chart below. also, notice the drop in SHBG as vitamin D and T increase. it wasn’t a focus of the study, but that would also mean more free T to actually do the work we want it to do.

It  looks like 90-130 nmol/L is the optimal zone.    Reference ranges for blood tests for reference ranges of numerous hormones and blood constituents with a handy, multi-scale reference for changing readings from one unit to another. if you only get this from my article, it will have been worth your time to read this far.
