EAA (Essential Amino Acids) — all 9 essential amino acids the body needs and cannot produce on its own. The evolution of BCAA — a more complete formula that activates protein synthesis more effectively.
What is new in EAA? Research from 2017-2020 confirmed that 3 amino acids in BCAA are not enough — protein synthesis needs all 9 EAAs. EAA formulas fix this: leucine + isoleucine + valine + histidine + lysine + methionine + phenylalanine + threonine + tryptophan.
When choosing EAA, key criteria: complete 9-amino profile, optimal leucine amount, correct dosing.
A quality EAA label shows all 9 amino acids separately in mg: leucine 2500mg, isoleucine 1250mg, valine 1250mg, histidine 250-500mg, lysine 1000-1500mg, methionine 250-500mg, phenylalanine 500-800mg, threonine 500-800mg, tryptophan 150-300mg. If the label is missing some — it is not a complete EAA.
Leucine (2.5-3g per serving) — the main trigger of protein synthesis. The "Leucine Threshold" — 2.5g in a single intake is required for maximum synthesis activation. If an EAA serving contains less than 1.5g of leucine, it is a marketing dose with minimal effect.
Protein is complete — EAA + BCAA + non-essential amino acids. 25g whey protein contains about 10-12g EAA. If protein powder covers your needs, separate EAA is redundant. EAA is better for: fasted training (fast absorption, no protein), during-workout use (does not sit heavy in stomach), protein intolerance.
