Dietary Protein Source Linked to Testosterone Levels in Men
For men, the source of dietary protein—animal (especially dairy) versus plant—appears to correlate with significant differences in circulating testosterone levels, suggesting a potential modifiable lifestyle factor. Currently, dietary interventions specifically differentiating between animal and plant protein for modulating testosterone levels are not a standard component of clinical practice beyond general healthy eating guidelines.
