Why per 10 g of EAA
A scoop holds more than EAA. Flavor, sweetener and salts add weight and price: a 12.9 g scoop of RAW Nutrition EAA Plus, Watermelon Grape holds 9.25 g of the nine. So we price 10 g of the nine essential amino acids, the amount the label states. Capsules hold little, so they cost more per 10 g.
What EAAs do and how much to take: what the research says.
12 EAA products we checked but did not price
- Optimum Nutrition Essential Amino Energy: Its 5 g 'Amino Blend' mixes essential and non-essential amino acids with no amounts, and it carries 100 mg of caffeine, so we cannot count grams of the nine. Informed Choice and Informed Sport list other versions (Hydration + Focus, Elite Series).
- BodyHealth PerfectAmino (powder and tablets): Its panel gives one 5 g blend of essential amino acids mixed with nucleic-acid ingredients, so the grams of EAA are not stated. The NSF Certified for Sport versions (Mixed Berry and Vanilla powder, coated tablets) carry the same blend.
- OptimalAmino (powder and tablets): Its NIH label (DSLD 295109) gives a 10 g blend that names eight amino acids with no amounts; histidine is not listed.
- Sunwarrior Active Aminos: Its 8 g 'EAA' blend also lists tyrosine, a non-essential amino acid, and gives no amounts, so we cannot say how many grams of the nine it holds.
- GNC Pro Performance Essential Amino Complete: No list price we can cite, and no Amazon listing we could price.
- Pure Power (Mercola) EAA + BCAA: On NSF Certified for Sport, but no live Amazon offer and no list price we could read (the brand's product page was gone, 2026-10-07).
- Transparent Labs Intra Workout EAA: Its 6.7 g 'Amino9' blend gives no amounts, and we did not find it on Amazon (2026-10-07).
- Xtend EAA + BCAA (40 servings): No label we can read: the brand store does not list it, and the Amazon title's '10g EAAs' could not be checked (2026-10-07).
- Pure Encapsulations Essential Aminos: No list price we can cite: the brand sells through practitioners, and we do not use Amazon prices. Its NIH label gives 0.725 g of EAA a capsule.
- The Amino Company Perform: A hidden blend with no tryptophan, plus caffeine, creatine and citrulline: not a nine-EAA product.
- NOW Sports Amino Complete: On Informed Sport, but it is a blend of protein sources (whey, soy, casein), not free essential amino acids.
- Spoken Nutrition Aminos + ATP: On NSF Certified for Sport, but we found no Amazon listing and could not read its panel amounts.
