http://www.ncbi.nlm.nih.gov/pubmed/21154195 http://www.ncbi.nlm.nih.gov/pubmed/21154195 The evidence is strongly suggestive that vitamin D supplementation has an effect on testosterone levels in men. On a purely anecdotal, personal level, I had my free test checked some years back, before I started vitamin D supplementation. After supplementing with 10,000 IUs a day for around a year, I had it checked again and it was significantly higher (I don't have the numbers now, sorry).

10 000 IU a day? Was that a typo? How did you got that target? Just asking because I was considering 10 000 IU a week following my MDs advice (which is already higher than what it the normal off the shelf dose: 1000 IU a day).

  I'm also taking 10,000 UI daily. Anything below 20,000 UI daily is fine and non-toxic. References - pubmed.

    Although safe, according to current search, there's no benefits from supplementing 10,000 UI daily (2,000-5,000 being recommended dose) — http://examine.com/supplements/Vitamin+D/ http://examine.com/supplements/Vitamin+D/ This doesn't prove that 10,000 is unnecessary, but there's no proof that it's necessary either :) (or is there?) On the other hand, just recently a Polish study showed 6,000 IU improving rowers metabolism and performance — http://suppversity.blogspot.com/2015/02/6000iuday-of-vitamin-d3-could-trigger.html http://suppversity.blogspot.com/2015/02/6000iuday-of-vitamin... However, it's unclear if lower dose would lead to similar results or if this is due to any other factors.
