One study found a close correlation between vitamin D deficiency and low testosterone. When participants spent more time in the summer sun and their vitamin D levels increased, so did their testosterone levels .In a year-long study, 65 men were split into 2 groups. Half of them took 3,300 IU of vitamin D every day. The supplement group's vitamin D levels doubled and their testosterone levels increased by around 20%, from 10.7 nmol/l to 13.4 nmol/l .
