Plant protein blend combining pea and rice proteins provides all essential amino acids, particularly high levels of lysine and methionine that complement each other. This combination activates mTOR signaling pathways and stimulates muscle protein synthesis while offering superior digestibility compared to single plant proteins.
Reported Benefits (Provisional)
Origin & History
This blend combines pea and rice proteins, providing a complete amino acid profile. It is produced by extracting proteins from peas and rice grains.
Research Narrative (Provisional)
Research indicates that plant protein blends can be as effective as animal-based proteins for muscle growth, supported by various studies and meta-analyses.
Preparation & Dosage
Dosage guidance is withheld because the publication gate has not recorded adequate support for this profile.
Nutritional Profile
Per 30 g serving (typical scoop): Protein: 20–25 g (pea protein isolate ~70% + brown rice protein concentrate ~30%, combined to yield a complete amino acid profile with a PDCAAS of ~0.9–1.0). BCAAs: ~4.5–5.5 g (Leucine ~1.5–2.0 g, Isoleucine ~1.0–1.2 g, Valine ~1.0–1.3 g). Lysine: ~1.4 g (primarily contributed by pea protein, compensating for rice protein's lysine deficiency). Methionine + Cysteine: ~0.8–1.0 g (primarily contributed by rice protein, compensating for pea protein's sulfur amino acid limitation). Total fat: 1.5–3.0 g (predominantly unsaturated; trace amounts of linoleic and alpha-linolenic acid). Carbohydrates: 1.5–4.0 g (of which dietary fiber ~0.5–1.5 g, primarily soluble fiber from residual pea fiber). Sugars: <1 g. Calories: 100–130 kcal. Iron: 5–8 mg (~30–45% DV; non-heme form from pea protein; bioavailability ~5–12%, enhanced when consumed with vitamin C). Sodium: 250–400 mg. Potassium: 50–100 mg. Calcium: 30–60 mg (~3–5% DV). Magnesium: 20–40 mg (~5–10% DV). Phosphorus: 150–250 mg (~15–25% DV). Zinc: 1.5–2.5 mg (~15–22% DV; note phytate content may reduce bioavailability to ~15–25% absorption rate). Bioactive compounds: Saponins (trace, from pea protein) with potential cholesterol-lowering and immunomodulatory properties. Phytic acid: 0.1–0.5% (acts as both an antinutrient reducing mineral absorption and an antioxidant). Gamma-oryzanol: trace amounts from rice protein (~1–3 mg), associated with lipid metabolism support and antioxidant activity. Phenolic compounds: trace (~5–15 mg gallic acid equivalents per serving from rice bran residues). Bioavailability notes: The pea-rice blend achieves amino acid complementarity, with rice protein supplying methionine/cysteine and pea protein supplying lysine, resulting in a digestibility comparable to whey (~90–95% true ileal digestibility). Protein absorption rate is moderate (~3–4 g/hour), providing a sustained aminoacidemia versus whey's rapid spike. The hypoallergenic profile (free of major allergens: dairy, soy, gluten, egg) supports superior gastrointestinal tolerance. Mineral bioavailability can be improved by enzymatic processing or co-ingestion with organic acids (e.g., vitamin C for iron, citric acid for zinc).
Reported Mechanism (Provisional)
Pea protein supplies high levels of branched-chain amino acids (leucine, isoleucine, valine) that activate mTOR (mechanistic target of rapamycin) pathways, triggering muscle protein synthesis. Rice protein contributes methionine and cysteine, creating a complete amino acid profile that matches whey protein's biological value. The complementary amino acid profiles ensure optimal nitrogen retention and protein utilization efficiency.
Clinical Narrative (Provisional)
A 12-week randomized controlled trial with 161 resistance-trained men showed pea protein increased bicep muscle thickness by 20.2% compared to 15.6% with whey protein. Studies on rice protein demonstrate 12-24g doses effectively stimulate muscle protein synthesis rates comparable to whey protein. Combined pea-rice blends show 95-100% digestibility scores in clinical assessments, though long-term comparative studies against animal proteins remain limited.
