Re: Study: vitamin D increases testosterone levels
It sounds like they mainly found correlation, not causation.
In other words, testosterone and Vitamin D levels may be associated, but that's not the same thing finding that vitamin D supplementation will cause higher testosterone levels, especially with a statement like the following: "Some of the men were using their own vitamin supplementation which included vitamin D, but their testosterone levels were only slighly higher than normal"
Still, interesting stuff (and yet ANOTHER reason that whole milk, which contains fat soluble vitamin D that is readily absorbed, may be better than steroids for novices, haha). Thanks for posting it. I hope this spurs more, similar, research.
