Vitamin D and Testosterone Levels

[DaRoq]

I recently read an article which suggests that most Western Men make too little testosterone due to Vitamin D deficiency. The science is that vitamin D regulates the genes that are responsible for the production of testosterone in the Leydig cells. It also lowers SHBG, which is a factor in free testosterone levels.

Keep in mind that the Austrian study included 2300 men over the age of 60, so the effects on younger men may vary. You can read more here.

I believe Effect of vitamin D supplementation on testosterone levels in men. is the MEDLINE abstract for that study.

Nice article - we have been saying here for years that most men are deficient these days in Vit D levels. I think it is very important for it to be included in every lab panel, and to supplement as necessary to be in the upper range.

We had a nice vitamin D discussion about a month and a half ago.

Everyone was deficient lol.

I'm currently taking a walmart gel cap of 5k IU D3 with breakfast and dinner.

vitamin D test is too damn expensive! one of my customers (Quidel Corporation) is developing a vitamin D strip test, hopefully it will be in the market and OTC soon.

I am trying this to bump me above 700 and see if i can get off TRT, or at least stay on very small dosage. My levels where at 640 before starting TRT , read the post ignorant doctors LOL

This is really interesting that you posted this. Kelkel and I were discussing this very subject a few days ago, and I told him that I was on the hunt to find some sort of correlation between low "T" and vitamin D deficiency. You just tapped into what I was looking for, thanks for posting.

On a side note for vitamin D therapies ... My doctor just put me on a prescription of Drisdol; taking one tablet of 50,000iu per week. It's basically Vitamin D2 . I just started my 2nd week. My doctor feels this is by far a better route to go as opposed to any of the OTC products that I had been using, so I'm anxious to see how my next set of labs turnout.

I was taking 10,000 IU of D a day, in an oral oil capsule. It raised my D blood levels from 25 to 32. I switched to SuperiorSource sublinqual D (10,000 IU) and my D blood levels went up to 58 -- right where I want them. For me, sublingual D absorbed better.
