Testosterone levels related to Vitamin D up by 30ng
Data from a small randomized controlled trial suggest that vitamin D supplementation might increase the production of testosterone in men.[1] In that trial, 54 healthy men whose mean 25(OH)D levels were in the deficiency range (mean 29·7 nmol/l in the placebo group and 32·5 nmol/l in the vitamin D group; to convert nmol/l to ng/ml, divide by 2·5) received either 83 ?g vitamin D daily for 1 year (n = 31) or placebo (n = 23). Compared with baseline values, a significant increase in total testosterone levels (from 10·7 ± 3·9 to 13·4 ± 4·7 nmol/l; P < 0·001) was observed in the vitamin D supplementation group. Similar increases were observed for free testosterone and bioactive testosterone. No changes in testosterone concentrations were observed in the placebo group.

I don't think I'd stop supplementing because of a small recent study reports an increase, the info is for you to better understand what may affect your T levels. It's just a possible solution.
