When looking at supplements for boosting testosterone, several options have been found to have some evidence supporting their effectiveness:

1. Vitamin D: Vitamin D helps regulate testosterone levels¹. It is essential to maintain adequate vitamin D levels, particularly through sunlight exposure and supplementation if necessary.

2. Zinc: Zinc is critical for testosterone production and maintaining healthy levels². Men with zinc deficiencies have shown increased testosterone levels when supplemented with zinc.

3. Magnesium: Magnesium supplementation can boost testosterone levels, especially in individuals with a deficiency³.

4. Fenugreek: Fenugreek seed extract has shown positive effects on testosterone concentrations in several studies⁴.

5. Ashwagandha: Ashwagandha root and root/leaf extracts have been demonstrated to potentially increase testosterone levels⁴.

It's important to note that these supplements tend to be effective primarily if there is a deficiency or insufficiency in the respective nutrient or herb. More extensive research is necessary, especially in larger, diverse populations, to establish conclusive evidence. Moreover, many "testosterone boosting" supplements on the market do not have sufficient evidence to support their claims, and in some cases, might exceed recommended daily allowances for certain vitamins and minerals⁵⁶.
