5 supplements in this category
BCAA
The classic intra-workout amino, but largely redundant if you eat enough protein. EAAs offer a more complete profile for the same price.
Dose: 5–10 g per serving
Essential Amino Acids (EAA)
All 9 essential amino acids in one — outperforms BCAAs for muscle protein synthesis at equivalent doses. Useful for fasted training or low-protein meals.
Dose: 8–15 g per serving
L-Glutamine
Most-abundant amino in the body, popular for gut healing and immune support during heavy training. Muscle-building claims are largely overstated.
Dose: 5–15 g daily
L-Arginine
Nitric oxide precursor — but most arginine is broken down in the gut. L-citrulline raises blood arginine more reliably for pumps.
Dose: 3–6 g daily (acute)
L-Citrulline
Pre-workout staple for vasodilation and reduced muscle soreness. Raises plasma arginine more efficiently than arginine itself.
Dose: 6–8 g pre-workout (citrulline malate 8 g)
