Pros and cons
BCAA Glutamine
- 8 g of fermented, vegan BCAAs in a fully disclosed formula
- No sucralose, acesulfame potassium or artificial dyes
- Brand reports third-party testing of every batch and Informed Choice certification
- Buyers rate its quality and digestibility highly
- BCAAs add little for people who already eat enough protein
- 1,500 mg vitamin C per scoop; three scoops would exceed the adult upper limit
- Taste is the most frequent complaint in buyer reviews
- About $1.33 per serving
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
BCAA Glutamine
This is a thoughtfully formulated BCAA drink with a clean label and certification, but it is expensive, divisive on taste and built on an ingredient class with weak evidence for people who eat enough protein. The megadose of vitamin C is unnecessary and adds up quickly if you follow the label's multi-scoop directions. An EAA product or a protein shake is the better buy.

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.
