Potentially. Vitamin D status was associated with androgen levels in men in an observational study,[1] and a randomized controlled trial found that Vitamin D supplementation (around 3000 IU/day or 75 μg/day) increased testosterone levels in healthy overweight men.[2] It is important to note that vitamin D supplementation has not been shown to increase testosterone to supraphysiological levels, nor is there any evidence that supraphysiological vitamin D intake will further enhance testosterone levels beyond moderate-level supplementation. More research is needed to determine the effects of vitamin D supplementation on testosterone levels in different populations.
Can vitamin D status affect testosterone levels?

Vitamin D status may influence testosterone levels because observational studies and a randomized controlled trial have suggested that supplemental vitamin D can increase testosterone in men with overweight but without other health conditions. However, supplementation does not raise testosterone to supraphysiological levels, and further research is needed to explore its effects across different populations.
