Does Vitamin D Increase Testosterone?

The deficiency of vitamin D and its potential impact on testosterone levels have been subjects of scientific interest, as concluded in this research aimed at evaluating low levels of vitamin D and testosterone in adult males:

• Men with the lowest levels of vitamin D had significantly lower testosterone concentrations compared to those with the highest levels.

Therefore, a lack of vitamin D may reduce testosterone production.

Effects of Vitamin D on Testosterone

The deficiency of vitamin D and low testosterone concentrations in men can affect various areas of health, including:

The study results showed that healthy men with low vitamin D levels and high parathyroid hormone concentrations had lower testosterone and LH ratios in the blood, suggesting that the effect of LH on testosterone production may be reduced when vitamin D is low.

In contrast, the men who had a testicle removed received an injection of human chorionic gonadotropin to test the remaining testicle’s ability to produce sufficient testosterone.

It was found that the vitamin D concentration in the blood of this group showed that men with low vitamin D levels responded less positively to the gonadotropin injection compared to men with normal or high vitamin D concentrations.

Researchers also studied whether vitamin D can directly stimulate testicular tissue to produce testosterone. To do this, healthy testicular tissue was extracted from the subjects who had cancer, and it was cultured in the laboratory, applying activated vitamin D. This showed that, the tissue exposed to vitamin D produced more testosterone.

In other evaluations, participants who received vitamin D showed relatively small but statistically significant increases in testosterone compared to the placebo: total testosterone levels increased by 3 nmol/litre to 13.4 nmol/litre after 12 months. A similar trend was observed with bioavailable testosterone and free testosterone.

When to Get Vitamin D Tested?

To determine your vitamin D status, it is recommended to have a blood test that can measure vitamin D in two forms, 25-hydroxyvitamin D and 1,25-dihydroxyvitamin D.

Indicators of low vitamin D levels may include symptoms such as: fatigue, muscle weakness, frequent bone fractures, or hair loss.

How to Increase Vitamin D?

Key recommendations for maintaining optimal vitamin D levels include:

At HSN, we recommend consulting a health professional if you have any doubts about using vitamin D supplements.

Conclusions

A large majority of the population has low vitamin D levels, due to various factors, such as reduced sun exposure, indoor work, or nutritional deficiencies.

In Spain, despite the high number of sunlight hours, this circumstance occurs, as reflected in this research.

In the case of men, as we’re discussing in this post, this vitamin D deficiency can influence maintaining low testosterone levels, with all that this entails, both in terms of health and physical effort (for athletes).

Strategies to increase the levels of this essential vitamin should be a priority for the proper functioning of our body:
