L-Glutamine
The most overlooked recovery supplement. The simplest upgrade you can make.
Hard training depletes glutamine faster than your body can synthesize it. One ingredient. Pure powder. 3.15g per scoop. Nothing else in it.
L-Glutamine is the most abundant amino acid in the body and the primary fuel source for intestinal cells and immune tissue. When training volume is high, exogenous glutamine keeps the recovery pipeline full.
Simple. Single ingredient. No fillers. Just 3.15g pure glutamine per scoop.
- You train at high frequency or volume
- You experience gut discomfort during training blocks

Do I need glutamine if I already eat enough protein?
Protein provides amino acids including glutamine, but under high training loads your body's demand can outpace synthesis. Glutamine is conditionally essential — normally non-essential, but becomes essential under physiological stress. Athletes training at high frequency or volume consistently benefit from exogenous supplementation even with adequate protein intake.
How does glutamine help with gut health?
The cells lining your intestinal wall (enterocytes) use glutamine as their primary fuel source. Hard exercise increases gut permeability — sometimes called "leaky gut" — by diverting blood flow and stressing intestinal lining. Supplementing glutamine helps maintain intestinal integrity, reducing digestive discomfort, bloating, and permeability associated with heavy training.
Does it taste like anything?
Virtually nothing. L-Glutamine powder is nearly flavorless with a very slight sweetness. It dissolves cleanly in water, shakes, or any post-workout drink without affecting taste. This makes it one of the easiest supplements to add to an existing protocol without changing your routine.
When is the best time to take it?
Post-workout is optimal because glutamine uptake is elevated after training. That said, any consistent daily timing works — before bed is a good secondary option as it supports overnight gut repair. The most important variable is consistency, not precise timing.
