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.
