Quick Buying Guide — Amino Acids

EAA vs BCAA: EAAs (essential amino acids) cover the full set your body can''t make on its own; BCAAs are a narrower subset focused specifically on muscle recovery. EAAs are the broader, generally better-value choice unless you specifically want a BCAA-only product.
Form: Powder mixes into water and absorbs fastest; capsules and tablets are easier to dose on the go but usually cost more per serving.
Servings per container: Check servings, not just container size — serving sizes vary enough between brands that price-per-serving is the only fair comparison.
Count (capsules/tablets): A higher count doesn''t mean a stronger dose — check the per-serving amount, since some products need 4–6 capsules per serving.
Container weight: Useful for comparing powders by bulk, but pair it with servings rather than judging by weight alone.
