Essential amino acids (EAAs) are nine amino acids the body cannot synthesize, including leucine, isoleucine, and valine. They directly stimulate muscle protein synthesis through mTOR pathway activation and provide substrate for new muscle tissue formation.
Reported Benefits (Provisional)
Origin & History
Essential Amino Acids (EAAs) are the nine amino acids that the human body cannot synthesize and must be obtained through diet. They are found in complete protein sources and are crucial for various bodily functions.
Research Narrative (Provisional)
Research indicates that EAAs are crucial for muscle protein synthesis and recovery. Studies have shown they may enhance muscle growth and repair when taken around exercise sessions.
Preparation & Dosage
Dosage guidance is withheld because the publication gate has not recorded adequate support for this profile.
Nutritional Profile
EAA full-spectrum supplements typically deliver all 9 essential amino acids per standard 10-12g serving: Leucine (2000-3000mg, primary mTOR activator and muscle protein synthesis trigger), Isoleucine (1000-1500mg, supports glucose uptake and hemoglobin synthesis), Valine (1000-1500mg, supports energy metabolism and neurological function), Lysine (1000-1500mg, collagen synthesis and calcium absorption support), Threonine (500-1000mg, immune function and connective tissue support), Phenylalanine (500-1000mg, neurotransmitter precursor for dopamine and norepinephrine), Methionine (250-500mg, methylation reactions and antioxidant glutathione precursor), Histidine (300-600mg, carnosine precursor and immune modulator), Tryptophan (150-300mg, serotonin and melatonin precursor). Macronutrient breakdown per 10g serving: protein/amino acids 8-10g (80-100% of content), carbohydrates 0-2g (varies by formulation), fat 0g, calories 30-45kcal. Micronutrients are generally absent unless fortified. Bioavailability notes: free-form crystalline EAAs achieve peak plasma amino acid levels within 30-60 minutes, significantly faster than whole protein sources (90-120 minutes); absorption rate approximately 95-99% with no digestive breakdown required; leucine threshold of ~2-3g per serving is critical for maximizing muscle protein synthesis signaling via mTOR pathway; co-ingestion with carbohydrates enhances insulin-mediated uptake but is not required for efficacy.
Reported Mechanism (Provisional)
EAAs activate the mechanistic target of rapamycin (mTOR) signaling pathway, particularly through leucine binding to Sestrin2 proteins. This triggers phosphorylation of ribosomal protein S6 kinase 1 (S6K1) and eukaryotic translation initiation factor 4E-binding protein 1 (4E-BP1), initiating muscle protein synthesis. The branched-chain amino acids (leucine, isoleucine, valine) also reduce protein degradation by inhibiting the ubiquitin-proteasome system.
Clinical Narrative (Provisional)
Multiple randomized controlled trials with 12-40 participants show EAA supplementation (10-15g) increases muscle protein synthesis rates by 50-100% compared to placebo. A 12-week resistance training study found EAA supplementation improved lean mass gains by 2.3kg versus 1.4kg in controls. Endurance studies demonstrate 15-20% reduction in perceived exertion and delayed fatigue during prolonged exercise. Evidence quality is moderate with consistent but small sample sizes across studies.
