Effect of vitamin D supplementation on testosterone levels in men – Source: Hormone and Metabolic Research, Dec 10, 2010

By S Pilz, et al. • www.ProHealth.com • December 23, 2010


The male reproductive tract has been identified as a target tissue for vitamin D, and previous data suggest an association of 25-hydroxyvitamin D [25(OH)D] with testosterone levels in men [vitamin D3].

We therefore aimed to evaluate whether vitamin D supplementation influences testosterone levels in men.

Healthy overweight men undergoing a weight reduction program who participated in a randomized controlled trial were analyzed for testosterone levels. The entire study included 200 nondiabetic subjects, of whom 165 participants (54 men) completed the trial.

Participants received either 83 micrograms (3,332 IU) vitamin D daily for 1 year (n=31) or placebo (n=23).

Initial 25(OH)D concentrations were in the deficiency range (less than 50 nmol/l) and testosterone values were at the lower end of the reference range (9.09-55.28 nmol/l for males aged 20-49 years) in both groups.

Mean circulating 25(OH)D concentrations:

• Increased significantly by 53.5 nmol/l in the vitamin D group,

• But remained almost constant in the placebo group.

Compared to baseline values:

• A significant increase in total testosterone levels (from 10.7±3.9 nmol/l to 13.4±4.7 nmol/l; p<0.001), bioactive testosterone (from 5.21±1.87 nmol/l to 6.25±2.01 nmol/l; p=0.001), and free testosterone levels (from 0.222±0.080 nmol/l to 0.267±0.087 nmol/l; p=0.001) were observed in the vitamin D supplemented group.

• By contrast, there was no significant change in any testosterone measure in the placebo group.

Our results suggest that vitamin D supplementation might increase testosterone levels. Further randomized controlled trials are warranted to confirm this hypothesis.
