    Hi IAW,

    It is always great to hear success stories with vitamin D! In djbinding’s case, he had low levels of vitamin D, low levels of testosterone, and sufficient vitamin D supplementation to achieve healthy levels. It is quite possible that they didn’t observe significant effects due to such low vitamin D dosage, and since the participants already had healthy levels of testosterone.

    I reached the same conclusions as this study… with 153 male athletes with median D 28 ng/L had no correlation with Testosterone (data yet unpublised).

    But the caveat is that we did not supplement them and the supplementation in this current article is ludicrious (600 – 1200).

    Hope to see if VERY insufficient males (below 20 ng/mL) AND testosterone deficient can get their testosterone back just by supplementing vit D … THAT would be a HUGE study, since recently the NIH said that testosterone replacement therapy is dangerous.

    It is a shame that so much money is spent to prove that inexpensive remedys don’t work.

    I have said that neither my wife or I have had the flu or colds for at least ten years. That is about the time that I “found” this site.

    Exercise is another very inexpensive “treatment.” Athletes are bound to be more healthy in many ways.
