Citrulline is a key dietary amino acid most popularly used in sports nutrition supplements. Early evidence suggests that citrulline testosterone effects may help boost T levels through:
- Inducing testosterone. A single animal study has associated elevated testosterone with increases in citrulline production.
- Bolstering erectile function. It may mimic the effects of testosterone on sexual function.
