"3x more leucine for muscle recovery and growth"
No milligram amount is shown, so this comparison claim can't be checked against competitors.
-
"Capsules deliver effective amino acid doses"
Clinical studies use 10-15 grams of EAAs per serving, hard to fit in a capsule format without many pills.
Consumer advice
Check the supplement facts panel on the actual Amazon listing before buying — look for the total grams of amino acids per serving, not just "9 essential aminos" or "3x more leucine." If a serving requires swallowing 6+ capsules to get a meaningful dose, a powder form will be cheaper and easier to dose accurately. If you already eat enough protein (about 1.6-2.2g/kg bodyweight daily from food), this supplement likely won't add much benefit.
