Each scoop delivers pure L-Glutamine, a key building block for muscle tissue, to help you bounce back faster from intense workouts.
The standout feature is its ability to maintain a positive nitrogen balance, which is crucial for muscle repair and growth.

- Certified manufacturing ensures purity and potency
- Great value with a generous serving count
- Suitable for gluten-free and non-GMO diets

Nutricost L-Glutamine 800mg capsules are a straightforward, no-fuss supplement designed for those seeking the benefits of this key amino acid without the hassle of measuring powders. L-Glutamine is the most abundant amino acid in the body, playing a crucial role in muscle protein synthesis, immune function, and gut health. This product is particularly suited for athletes, bodybuilders, and active individuals looking to support recovery after intense workouts, as well as anyone aiming to maintain a healthy digestive tract.
The standout feature of this supplement is its purity and quality. Each capsule delivers 800mg of L-Glutamine, with 180 capsules per bottle, providing a generous supply. The product is non-GMO and gluten-free, catering to those with dietary restrictions or preferences. Real-world performance is reliable, as the capsules dissolve quickly in the stomach, making the glutamine readily available for absorption. Users can expect to support muscle repair and reduce soreness when taken post-exercise, though individual results may vary.
Design and build quality are solid. The capsules are a standard size and are packaged in a robust red bottle that protects the contents from light and moisture. The manufacturing facility is NSF Certified, GMP Compliant, and FDA Registered, which adds a layer of trust regarding the product's purity and potency. However, the capsule size might be a bit large for some individuals, and those who prefer flavored or mixable supplements may find the plain capsule less appealing.
A potential drawback is the dosage per capsule. While 800mg is adequate for general wellness and light athletic recovery, serious athletes or those with high demands may need to take multiple capsules to reach the typical 5-10 gram daily dose. This could lead to a higher cost per serving compared to bulk powder forms. Additionally, there are no added flavors or fillers, which is a pro for purists but a con for those who dislike swallowing pills.
Overall, Nutricost L-Glutamine 800mg capsules offer a high-quality, convenient option for supplementing with L-Glutamine. They are best for individuals who value ease of use, purity, and a trusted manufacturing process over cost savings from powder forms.

Buying Guide: Glutamine Powder vs Capsules
When choosing between glutamine powder and capsules, consider your daily routine, dosing preferences, and how your body responds. Here are four key criteria to guide your decision.
Convenience and Portability
Capsules win hands-down for on-the-go use. You can toss a bottle in your gym bag or travel kit without worrying about spills or needing a shaker cup. The Nutricost capsules offer 800mg per serving, making it easy to take a precise dose anywhere, anytime.
Powder, on the other hand, requires a scoop and a liquid to mix. It’s less portable but more flexible for those who prefer to mix it into a post-workout shake or smoothie. If you’re always on the move, capsules might be your best bet.
Dosing Flexibility
Powder offers superior dosing flexibility. With the NOW Sports powder, you can easily adjust your serving size from a half scoop to a full scoop, depending on your needs. This is ideal for athletes who require higher doses, such as 5 to 10 grams per day, which is common for muscle recovery.
Capsules provide a fixed dose, which is convenient but less adjustable. To match a typical 5-gram dose, you’d need to take multiple capsules (about 6 of the Nutricost 800mg capsules). That’s a lot of pills to swallow. If you prefer a hassle-free, precise dose, capsules are great, but powder gives you more control.
Absorption and Taste
Glutamine powder dissolves easily in water or juice, and many users find it has a mild, slightly sweet taste. Some people prefer to mix it with a flavored drink to mask any bitterness. The NOW powder is unflavored, so it mixes well with anything.
Capsules bypass taste entirely, which is a plus if you dislike the flavor of glutamine. However, some research suggests that taking glutamine with food or liquid can enhance absorption, and powder allows you to do that seamlessly. For most, absorption is similar, but powder might have a slight edge for mixing with meals.
Quality and Purity
Both products are from reputable brands. NOW Sports is known for its rigorous quality control, with GMP certification and third-party verification. Nutricost also manufactures in an NSF Certified, GMP Compliant, FDA Registered facility, ensuring high standards. When choosing, look for products that are non-GMO and gluten-free, like both of these.
For those interested in overall muscle support, consider how glutamine fits into your broader supplement stack. You might also explore other amino acids like glutamine vs BCAA to see which benefits you more.
Final Thoughts
Both forms of glutamine are effective, but your choice comes down to lifestyle. If you value convenience and a no-fuss routine, Nutricost L-Glutamine 800mg, 180 Capsules is your best bet for on-the-go dosing. If you prefer flexibility and higher doses for intense training, NOW Sports, L-Glutamine Powder, Amino Acid is the way to go. Either way, you’re supporting your recovery and overall wellness.
