Looking for a clean, pure L-glutamine supplement without the fillers and additives that plague most options on the market? Naked Pure L-Glutamine delivers exactly what its name promises: a single-ingredient amino acid supplement made in the USA.
I’ve been testing this glutamine powder for muscle recovery and gut health support. The Naked Nutrition approach is refreshingly simple: just L-glutamine naturally fermented from plant sources, with no artificial sweeteners, flavors, or colors. After incorporating it into my daily routine, I found it delivers solid results for both workout recovery and digestive wellness.
What I Liked
Pure L-Glutamine with No Additives
The Naked difference is real: this supplement contains only L-glutamine. No fillers, no sweeteners, nothing artificial. For those who want to know exactly what they’re putting in their body, this transparency is valuable. The glutamine is naturally fermented from plant sources, making it suitable for vegan and non-GMO diets.
Third-Party Tested for Quality
Naked Nutrition conducts independent third-party testing for heavy metals and purity. This pharmaceutical-grade approach sets it apart from budget supplements that skip quality verification. When you’re taking something daily, knowing it’s been properly tested matters.

Excellent Mixability and Neutral Taste
The fine powder dissolves quickly without clumping. I mixed it with water, juice, and protein shakes without any issues. Unlike some unflavored supplements that leave a chalky aftertaste, this L-glutamine powder has a subtle, neutral taste that doesn’t interfere with whatever you mix it into.
Great Value with 200 Servings
At 1,000 grams with 5g servings, you get approximately 200 servings per container. For a quality glutamine supplement, this represents solid value compared to smaller containers that run out quickly. The serving size aligns with research-supported dosing for gut health and muscle recovery benefits.
Supports Gut Health and Muscle Recovery
L-glutamine plays a role in protein synthesis and helps minimize muscle breakdown between workouts. I noticed improved recovery times and less soreness. For those dealing with digestive issues like IBS, glutamine supports the intestinal lining and can help balance gut health. In my experience, consistent use made a noticeable difference for both workout recovery and digestive comfort.
What Needs Improvement
Higher Price Than Budget Alternatives
The price point sits higher than budget alternatives like NOW Foods glutamine capsules. If you’re looking for the cheapest option, this isn’t it. However, the quality ingredients and third-party testing justify the premium for those who prioritize purity over price.
Missing Scoop in Some Orders
Some customers have reported receiving containers without a measuring scoop included. While you can use any 5g scoop, it’s an inconvenience for a product in this price range.

Slight Smell When First Opened
A few users mentioned a slight vinegary smell when first opening the container. I didn’t find this to be a significant issue, and it doesn’t affect the taste when mixed. The unflavored nature means you’re tasting pure glutamine, which some may find less pleasant than flavored alternatives.
How It Compares
Naked vs. NOW Foods L-Glutamine: NOW Foods offers glutamine capsules at a lower price point, around $0.13 per serving. However, their capsule form means you’d need to take 10 pills daily to match Naked’s 5g powder serving. For convenience and absorption, the powder form wins.
Naked vs. Optimum Nutrition Glutamine: Optimum Nutrition provides a similar 5g serving of pure L-glutamine powder at competitive pricing. Both are unflavored and mix well. The main difference is Naked’s emphasis on plant-based fermentation and more transparent sourcing.
Naked vs. Jarrow Formulations: Jarrow offers USP-grade glutamine with GMP certification in both tablet and powder forms. Their pricing falls in the mid-range similar to Naked. Some users report Jarrow tablets are larger than expected, making capsules harder to swallow. For those who prefer powder supplements, Naked remains the cleaner option with its single-ingredient formula.
For BCAA users who already supplement with branched-chain amino acids, adding standalone glutamine like Naked provides targeted support without the additional ingredients found in complex pre-workout formulas.
Final Verdict
Naked Pure L-Glutamine earns a 4.5 out of 5 rating. It delivers exactly what the name promises: pure, single-ingredient glutamine with nothing to hide.
The combination of quality ingredients, third-party testing, and excellent mixability makes this a standout choice for anyone serious about supplementation. While the price sits above budget alternatives, the purity and transparency justify the investment for health-conscious users.
For muscle recovery and gut health support, Naked Glutamine is a solid choice that I’ll continue using.
