Pros and cons
EAA Powder
- About $0.67 per serving, among the cheapest EAA powders
- Lists all nine essential amino acids with a fully disclosed label
- 4.7 stars from roughly 890 buyer ratings, with taste widely praised
- Brand says every batch is tested by ISO-accredited labs
- 6 of 8 g are BCAAs; methionine is only 10 mg
- Less complete than the same money spent on protein powder
- No named third-party certification
- Blue Raspberry flavor carries a California Prop 65 lead warning on the brand site
Original BCAA Powder
- Fully disclosed label: 7 g BCAAs (2:1:1) plus 2.5 g glutamine
- Zero sugar and zero calories per serving
- 220 mg sodium and 170 mg potassium for training hydration
- Listed as NSF Contents Certified in NSF's official database
- Wide flavor range and 4.5 stars from 7,500+ buyer ratings
- BCAAs alone lack the other essential amino acids needed to build muscle
- Adds little for people who already meet daily protein needs
- Artificial sweeteners; the Blue Raspberry Ice label lists FD&C Blue Lake #1
- 'GLP-1 support' marketing is not backed by BCAA-specific evidence
Our verdicts
EAA Powder
Nutricost EAA is cheap, tasty and better grounded than a pure BCAA drink because it includes all nine essential amino acids. The formula is so BCAA-heavy, with only token amounts of several essentials, that it falls short of the balanced profile research favors. It is fine as a low-cost training drink, but a scoop of protein powder delivers more complete amino acids for similar money.

Original BCAA Powder
Xtend Original is a well-made, NSF Contents Certified, zero-sugar drink with a fully disclosed label. The weak link is BCAAs themselves: for anyone eating enough protein, research shows little added muscle benefit, and an EAA product or a protein shake is a better use of money. Buy it for taste and hydration, not for gains.
