Life Extension L-Glutamine, 500 mg L-glutamine, amino acid, supports muscle health and immune health, gluten-free, non-GMO, 100 vegetarian capsules
Key item features
- Fuel your active lifestyle—Glutamine is an amino acid your body uses for protein production. While it’s a must-have among serious athletes, glutamine is a great option for anyone who leads an active lifestyle.
- Gut healthy, immune strong—Glutamine can be found in the blood, as well as stored in the skeletal muscles and liver, and in higher concentrations than any other amino acid. It’s an important energy source for cells lining the gut and immune cells, making it critical for a healthy digestive tract and immune response.
- Antioxidant support—Regular body movement is terrific for whole-body health. But engaging in heavy exercise can affect glutamine levels, causing stress to the body. Our L-Glutamine formula helps support antioxidant defenses to maintain muscle health.
- Ingredients matter – We use only pure, high-quality ingredients. The majority of our products are non-GMO and gluten-free—and a Certificate of Analysis is available for every one.
- Live your healthiest life - For over 40 years, we’ve been developing advanced, effective formulas made with the highest standards and based on the latest scientific findings. We believe the answers to a healthier, richer life are within reach, and that rigorous scientific research is the path to get us there. That’s why so many of our nutritional formulas are designed using specific ingredients and amounts based on scientific studies.

About this item
Product details
Glutamine is an amino acid that your body uses to build protein. As such, it’s often taken in conjunction with muscle strength regimens. But glutamine can also help power immune cells, supporting an optimal immune response. It’s also beneficial to gut health. This L-glutamine supplement is non-GMO, vegetarian, gluten-free and delivers 500 mg of glutamine in every dose. Each bottle contains 100 vegetarian capsules.
