A foundational amino acid for recovery + gut support.
L-Glutamine helps support muscle repair, gut lining integrity, and immune health—making it a simple daily addition for athletes, active individuals, or anyone under higher physical stress.
L-Glutamine is the most abundant amino acid in the body and becomes especially important when physical demand is high. It helps support recovery by reducing exercise-related muscle breakdown, while also playing an important role in maintaining gut barrier function and fueling immune cells.
Benefits include:
- Helps support muscle recovery after long or intense workouts
- Supports protein synthesis and muscle repair
- Helps maintain a healthy gut lining
- Supports digestive comfort and gut function
- Fuels immune cells during times of physical stress
L-Glutamine is a conditionally essential amino acid involved in several key functions throughout the body. It supports protein synthesis and muscle repair, serves as an energy source for rapidly dividing cells, and plays an important role in immune function.
It is also especially valuable for gut health. L-Glutamine helps support the integrity of the gut lining and overall gut function, which is important for digestion, nutrient absorption, and whole-body resilience.
Mix 1 scoop daily with water or your preferred liquid.
Can be taken any time of day, including post-workout or alongside your daily routine. It also pairs well with protein or amino acid supplements.

- RDRobin D.Verified Buyer1 week agoRated 4 out of 5 starsEasy to take
Dissolves quickly. Has a taste in coffee but blends in with protein shake. Haven’t noticed results yet, maybe takes a bit longer. I’ll stick with it.
MMomentous4 days agoHi Robin,
Appreciate you sharing your experience with us. L-glutamine can be one of those supplements that works more subtly over time, so it’s not uncommon for results to take a bit longer to notice. With consistent daily use, most people tend to notice benefits after a few weeks, especially when it comes to gut support and recovery. Glad to hear it’s been dissolving well and easy to incorporate into your protein shakes. And happy to hear you're sticking with it!
Thanks again for leaving a review and for being part of the Momentous community. If you have further questions, please feel free to reach out to our Customer Care team. We're always happy to help!

Every morning in my yogurt works so well and I no longer need Metamucil. I love that it’s natural and doesn’t affect the flavor of my yogurt either.
