Fava bean peptides versus soy peptides
Soy is the most widely consumed plant protein in the world and has its own documented bioactive peptide profile. Soy peptides include lunasin, which has been studied for anti-cancer properties, and various ACE-inhibitory sequences. However, in direct antioxida

- Soy is the most widely consumed plant protein in the world and has its own documented bioactive peptide profile. Soy peptides include lunasin, which has been studied for anti-cancer properties, and various ACE-inhibitory sequences.
- However, in direct antioxidant comparisons after simulated intestinal transport, fava bean peptides outperformed soy peptides. The muscle-specific effects documented for fava bean peptides, particularly the clinical trial data showing 19.7% greater strength gains and 54% less strength loss, have no equivalent in the soy protein research literature. Soy also carries concerns about phytoestrogen content that some individuals prefer to avoid, particularly among those researching peptides for testosterone support.
