Benefits
14% higher EAA, 15% higher BCAA with whey protein
14% higher EAA, 15% higher BCAA with whey protein: acute ingestion of 25 g whey protein concentrate (WPC) with P3 Hydrolyzer led to 14% greater levels of essential amino acids (EAA) and 15% greater levels of branched-chain amino acids (BCAA) vs WPC + placebo. The amino acid uptake enhancement during the critical post-exercise anabolic window directly supports muscle protein synthesis.
Plant protein optimization — 295% more leucine
In standard in vitro gastric digestion experiments, P3 Hydrolyzer released 295% more leucine and 225% more BCAAs from plant protein. Plant proteins typically have reduced digestibility and bioavailability vs animal-based proteins — P3 Hydrolyzer addresses this fundamental limitation. The amino acid release enhancement is particularly meaningful for vegan/vegetarian athletes.
100% more amino acids from whey (in vitro)
Under simulated in-vitro gastric conditions, P3 Hydrolyzer released 100% more amino acids from whey protein and 228% more BCAAs from plant protein compared to other enzyme products. Demonstrates BIO-CAT's enzyme blend is more effective at liberating amino acids than competing enzyme formulations.
Enhanced satiety and appetite control
Enhanced satiety and appetite control: levels of the hunger hormone ghrelin were 11% lower in the WPC + P3 Hydrolyzer group vs WPC + placebo, and self-reported fullness and satiation were greater. The dual EAA + satiety effects make P3 Hydrolyzer relevant for GLP-1 users, where preserving muscle mass while reducing appetite is critical.
Pea protein clinical validation
Pea protein clinical validation: acute microbial protease supplementation increased net postprandial plasma amino acid concentrations after pea protein ingestion in healthy adults. Established proof-of-concept for plant protein optimization that the subsequent whey protein study extended.
GLP-1 medication support
P3 Hydrolyzer is designed to benefit those on GLP-1 medication (Ozempic, Wegovy, Mounjaro). GLP-1 medications cause appetite suppression with risk of muscle loss — enhanced EAA availability from limited protein intake helps preserve muscle mass. Emerging application area as GLP-1 usage expands across populations beyond diabetes.
Versatile — works with plant and animal protein
Versatile — works with plant and animal protein: P3 Hydrolyzer optimizes both plant protein (pea, faba, brown rice) and whey protein bioavailability. The dual versatility supports formulation flexibility — works in multiple protein categories. Featured in MuscleTech Plant Protein (250 mg dose per scoop).
Mechanism of action
Proteolytic enzyme amino acid liberation
P3 Hydrolyzer's three proteases (Acid Protease, Fungal Protease A from A. oryzae, Protease AM from A. melleus) work synergistically to cleave protein into peptides and free amino acids. Different proteases target different peptide bonds — the combination achieves more complete hydrolysis than single-enzyme products.
Enhanced gastric protein digestion
Proteins begin digestion in the stomach via pepsin and HCl. P3 Hydrolyzer's acid protease component works in the acidic gastric environment, supplementing endogenous pepsin. Enhanced gastric digestion produces more peptides and amino acids ready for intestinal absorption — accelerating the overall digestion timeline.
BCAA-specific liberation
P3 Hydrolyzer specifically enhances liberation of branched-chain amino acids (leucine, isoleucine, valine) — the BCAAs essential for muscle protein synthesis. Leucine specifically triggers mTOR pathway activation. 295% more leucine release from plant protein vs no enzyme supplementation indicates preferential BCAA liberation.
Anabolic window optimization
The post-exercise anabolic window (typically 2 hours after exercise) is when muscle protein synthesis is maximally responsive to amino acid availability. P3 Hydrolyzer's enhanced EAA uptake during this window directly translates to greater muscle protein synthesis vs the same protein dose without enzyme support.
Satiety hormone modulation
P3 Hydrolyzer reduced post-meal ghrelin (hunger hormone) by 11% in the whey protein trial. The mechanism likely involves faster amino acid availability triggering satiety signals earlier and more intensely. Combined with enhanced amino acid uptake, the dual effects make P3 Hydrolyzer valuable for weight management with muscle preservation.
Clinical trials

WPC + P3 Hydrolyzer led to 14% greater levels of essential amino acids (EAA) and 15% greater levels of branched-chain amino acids (BCAA) vs WPC + placebo. Hunger hormone ghrelin levels were 11% lower in WPC + P3 group. Self-reported sensations of fullness and satiation were greater during the WPC+P3 intervention. Established whey protein optimization alongside the prior pea protein evidence.
