Pea Protein (Yellow Split Pea Isolate · Concentrate)

Also known as: Pea protein isolate · Yellow pea protein · Pisum sativum protein

2 PMID anchor · MUSCULO · METABOLISM · Last reviewed 2026-06-04

Mechanism of action

  • Plant-source protein with relatively high leucine content among legumes (~8% of total AA)
  • mTORC1 / muscle protein synthesis activation when dose-matched to whey
  • Lower methionine and cysteine content vs animal sources (limiting amino acids)

Molecular + tissue targets

  • Skeletal muscle protein synthesis (Babault 2015 muscle thickness gains)
  • Plant-based dietary protein adequacy

Dosage range

25 g twice daily during resistance training for muscle thickness gains (Babault 2015 PMID 25628520 JISSN RCT n=161 males 18-35 · 12 weeks · double-blind placebo-controlled · pea > placebo significant on muscle thickness · pea ≈ whey without a significant inter-group difference)

Safety notes

Pea allergy is possible but uncommon; generally well-tolerated; lower digestibility-corrected amino acid score (PDCAAS ~0.7) vs whey (1.0), so consider blending with rice protein for a complete amino acid profile
