Transparent LabsBCAA Glutamine

Overview

Transparent Labs built its brand on fully disclosed labels without artificial sweeteners or dyes, and BCAA Glutamine follows that playbook. Each scoop delivers 8 g of fermented, vegan BCAAs in a 2:1:1 ratio, 5 g of L-glutamine, 1,500 mg of vitamin C, and 1 g of coconut water powder, naturally flavored and sweetened with stevia. The tub carries an Informed Choice seal for banned-substance testing, and the brand says every batch is tested by a third-party lab for purity and potency. A 30-serving tub costs $39.99, with flavors including Strawberry Lemonade, Blue Raspberry, and Sour Green Apple, plus an unflavored option.

What reviewers say

Reviewers consistently praise the clean ingredient list and generous doses. Naturally Made Essentials calls it one of the best BCAA supplements on the market, and FeastGood, who has tested much of the Transparent Labs lineup, ran it through a 30-day trial focused on soreness and recovery while asking the bigger question of whether BCAAs are worth buying at all. That skepticism is the main knock: the evidence for BCAAs building muscle is weaker than for complete protein, and at roughly $1.33 a serving you're paying a premium for cleaner ingredients. Transparent Labs also suggests two servings a day, which doubles the cost and pushes vitamin C to 3,000 mg.

Who it's for

Lifters who want a big BCAA dose without artificial sweeteners or dyes, plant-based athletes (the BCAAs are fermented and vegan), and lifters who value the Informed Choice seal (drug-tested competitors should look for Informed Sport or NSF Certified for Sport, which test every batch or lot).

Bottom line

On paper, this is the cleanest and most generously dosed BCAA formula in the lineup. If you've decided BCAAs fit your routine and ingredient quality matters to you, it's worth the premium over Xtend.
