Why It Works

Key Benefits

🏥
Gut Integrity Support
L-Glutamine serves as a primary fuel source for the cells lining your digestive tract. Adequate glutamine supports normal gut function and helps maintain the intestinal environment that promotes healthy nutrient absorption.*
💪
Muscle Recovery Support
Intense exercise can deplete circulating glutamine levels. Supplementing post-workout supports your body's natural muscle recovery processes and helps you stay consistent through demanding training cycles.*
🛡️
Immune Health
A healthy gut environment is closely connected to immune function. L-Glutamine supports the cells of the gut lining, which play a role in maintaining overall immune health and total well-being.*
🔬
Single Active Ingredient
Each serving delivers 3.15g of L-Glutamine with silicon dioxide as an anti-caking agent — and nothing else. A minimalist, transparent formula for those who value knowing exactly what they're taking.
⚡
Easy Daily Use
One scoop (5cc / 3.3g) mixes cleanly into 6–8 oz of water or your preferred beverage. Unflavored and odorless — add it to water, a protein shake, or any drink without affecting taste.

Editorial Team's Note
L-Glutamine is the most abundant free amino acid in circulation and the preferred fuel for intestinal epithelial cells. Research consistently shows that glutamine availability supports gut barrier function and immune cell activity — both of which can be compromised during intense training, caloric restriction, or periods of stress. I recommend K-Glutamine as a practical, clean-label addition to a daily routine for patients focused on gut health or active recovery. One scoop daily with water is all that's needed. As with any supplement, those with kidney disease, liver conditions, or who are pregnant or nursing should consult their physician before use.*

Pure L-Glutamine powder — physician-curated for gut integrity, muscle recovery support, and immune health. Vegan. Non-GMO. GMP certified. Made in USA.

L-Glutamine is the most abundant amino acid in the body and a primary fuel source for the cells lining your digestive tract. During intense exercise, caloric restriction, or periods of physiological stress, your body's demand for glutamine can exceed what it naturally produces — making supplementation a practical choice for those focused on recovery and gut health.

Kasivit K-Glutamine delivers 3.15g of L-Glutamine per serving in a clean, minimalist formula with a single active ingredient and silicon dioxide as an anti-caking agent. Each scoop (5cc / 3.3g) mixes easily into water or your preferred beverage, making it a straightforward addition to your daily routine — morning, post-workout, or any time that works for you.
