How We Picked These Glutamine Powders
You want a glutamine powder that actually helps you recover and feels easy to use. We prioritized: purity and ingredient list (no fillers or unnecessary additives), clinically useful serving size (around 3–5 g per serving), brand reputation and lab testing/NSF or similar certification when available, mixability and flavor neutrality so you can add it to water or shakes, value per serving, and real user feedback on gut effects and recovery.
We also considered whether a product targets specific needs like gut lining support or certified-for-sport safety if you compete.

🗣️ sandy
I’m a CrossFitter and sports massage therapist. I take this to help muscle recovery since I’m using my body daily. I do feel a subtle difference—soreness largely disappears when I take it. No taste or smell, smooth powder, easy to use; one scoop in the morning works for me.
🗣️ Fancy
I’ve been taking L-Glutamine a few weeks after reading about links to low levels in ADHD. This powder feels premium, mixes well with liquids and packs a punch in potency. Taste is better mixed; a full scoop is easy to take, and powder makes higher doses cheaper than capsules.
Long-Term Cost Benefits
At the current price of $14.97 for the 10.58 oz tub (about 300 g), there are roughly 60 servings at 5 g each, which works out to around $0.25 per serving. Subscribe & Save price ($12.72) drops the cost to about $0.21 per serving, making powder a cost-effective way to try Glutamine compared with capsule formats.

🗣️ harleykat
I am taking this in hopes of improving gut health so it is too soon to tell if it will help with that. This review pertains to taste and texture. It comes with a small scoop and It is a very fine powder that dissolves very easily in water. If I mix it with 12+ ounces it only has a slight taste and I can tolerate it when taking my supplements. I also try using it in my coffee but it really ruins the taste and it has a bad aftertaste as well. This is a problem bc most sources say that you need more than 20grams of L-glutamine for gut health. So far I’ve only taken about 15grams daily bc it is not very pleasant. Hopefully I’ll be able to continue it bc I am really sick of gut issues ruling my life. UPDATE 5 stars! Well it has been over 3 weeks since I started taking this L-glutamine and my gut health is really improving, I’m actually becoming regular and normal! After dealing with constipation and diarrhea for most of my adult life (getting worse with age to the point of it affecting my lifestyle and preventing me from participating in activities I enjoy). Well now I have hope that I will be able to engage in activities without worrying about where the nearest bathroom is. Things are not perfect but it’s much improved. I have also ordered butyrate in hopes that will help as well. This product is definitely worth it for anyone with gut issues, it is not something that will cause extremes one way or the other but it has helped me to center my digestion into a normal pattern and that is a fantastic result so far. Update #2: It has been just over 2 months since I’ve been taking L-glutamine and my digestive health is so much better, no episodes of diarrhea and virtually no constipation, I am so grateful for this supplement. I am taking 5gm in about 12oz of water with a scoop of Bloom first thing in the morning. I take another scoop over the coarse of the rest of the day. Also I have not altered my diet in any way that would account for this improvement. If you are suffering from digestive problems please try L-glutamine!
🗣️ DONNA JEAN MORAN
I ordered TypeZero brand unflavored L-Glutamine powder. It arrived within a few days. upon opening the plastic container there was no foul smell. The powder has a faint chalky, sweet taste. It quickly dissolved in tap water and I have had no adverse gut symptoms since ingesting this brand. At 200 servings of 5,000 MGs, the price is very reasonable. I usually buy NatureBell brand, but it is unavailable at this time. I am pleased with this brand.
Long-Term Cost Benefits
At the current list price of $31.95 for roughly 200 servings, each 5 g serving works out to about $0.16. If you prefer lower ongoing cost, subscribe options may lower the upfront price (subscribe base price shown at $28.75), which trims the per-serving cost even further and makes powder a budget-friendly way to try regular Glutamine dosing.

FAQ
What Are The Benefits Of Glutamine Powder For My Fitness Goals?
You can expect Glutamine to help in a few practical ways that support your training: it helps support muscle recovery and gut health, aids immune function during heavy training, and can reduce muscle soreness and breakdown when you train hard. It is not a magic muscle builder on its own — it works best as part of a balanced diet, adequate protein intake, and a proper training plan. Many users also report improved digestion and reduced bloating when taken consistently, which can help you feel and train better.
How Should I Use Glutamine Powder — Dosage, Timing, And Mixing Tips?
A common starting approach is to take about 5 g per serving; many products provide a 5 g scoop so you can start there and see how your body responds. You can take it post-workout for recovery or in the morning on an empty stomach if your goal is gut repair. If you prefer, split the dose into two 5 g servings, one post-workout and one between meals. Mix Glutamine into water, juice, or a shake; unflavored powders blend easily and won’t change the taste much.
Start with a lower dose if you are sensitive, monitor for mild side effects like headaches or changes in bowel habits, and increase only if needed and tolerated.
What Should I Look For When Buying Glutamine Powder And Are There Any Safety Concerns?
When you shop, prioritize purity and transparent labeling: check that the product lists plain L-glutamine as the only ingredient, shows grams per serving, and includes serving count so you can compare price per serving. Look for third-party testing or sport certifications if you compete; some premium options carry NSF Certified for Sport.
For example, Nutricost L-Glutamine Powder offers about 100 servings for $22.95, MuscleTech provides 5 g per serving at $16.99, and Thorne is a higher-cost option at $63.00 with a reputation for quality. Safety-wise, Glutamine is generally well tolerated but you should consult your healthcare provider before starting if you have kidney or liver disease, are pregnant or breastfeeding, or take prescription medications.
Expect occasional mild side effects such as headache, constipation, or minor GI upset in some people; stop use and seek advice if you notice worrying symptoms. Finally, avoid relying on Glutamine alone for progress — use it as a supplement to a solid nutrition and training plan.
Wrapping Up
Glutamine can be a simple, effective addition to your training and gut-health toolkit. If you train hard, a powder that delivers a clear dose per serving helps refill your muscles and reduces soreness. If you struggle with digestion or occasional bloating, daily glutamine can support intestinal lining repair and immune function.
Choose a product that matches your priorities: low cost per serving if you just want recovery, third-party tested if you need sport-safe assurance, or clinical-grade brands if gut health is the main goal. Start with a recommended dose (often 3–5 g once or twice daily), observe how your body responds, and consult your healthcare provider if you have chronic health conditions or take medications.
With the right choice, you’ll likely notice better recovery, steadier training, and improved digestive comfort.
