Pea Protein Isolate carries 2.0g more protein per 100g than Brown Rice Protein (80.0g vs 78.0g) — a real but modest edge.
On protein quality specifically, Pea Protein Isolate scores higher — DIAAS-adjusted, low in methionine, high in leucine for a plant source — compared to Brown Rice Protein, which is lit_estimate, low in lysine, typically blended with pea protein commercially.
Cost is roughly comparable between the two ($$), so budget isn't the deciding factor here.
Pea Protein Isolate's typical serving also delivers more leucine (2100mg vs Brown Rice Protein's 1750mg) — relevant if the goal is maximizing the muscle-protein-synthesis trigger per meal, not just total grams.
Protein quality is the real differentiator here: Pea Protein Isolate's stronger amino acid profile gives it a genuine edge for muscle-building purposes, even with similar gram counts.
