L-Glutamine Powder
Your gut lining needs fuel. So does your muscle tissue. This is what feeds both.
L-Glutamine is the most abundant amino acid in your body — and as you age, you're likely running low on it. Here's what that actually means, and why one scoop a day makes a measurable difference.
Benefits
The most abundant amino acid in your body, and the primary fuel your gut lining uses as it renews itself. One 3.15g scoop a day gives your body a steady supply to support the everyday maintenance of the intestinal barrier, plus post-exercise recovery.
The gut lining gets what it needs — enterocytes use glutamine as their primary fuel to maintain structure and repair themselves.
Recovery becomes more consistent — replenishing what strenuous exercise depletes supports muscle tissue repair.
Nutrient absorption improves — a well-supported lining absorbs what you eat and keeps out what you don't.
Immune function gets a foundation — roughly 70% of the immune system is housed in the gut.
One ingredient, no guesswork — 3.15g of L-Glutamine per scoop. That's the full label.

Your body relies on glutamine more than you think. Here's what that actually means.
Less glutamine
Your body has less available
The gut lining gets less support
Repair and maintenance slow down
You notice the difference
Digestion feels less resilient
Your gut lining renews itself constantly, and glutamine is one of the primary fuels for that process. When supply drops due to age, illness, stress, or heavy training, your body has fewer resources available to support and maintain the barrier that keeps digestion running smoothly.
Most gut supplements focus on digestion. This supports the lining itself.
The BuilderSupports the cells that line your gut
Gut lining support
Your intestinal lining is constantly renewing itself. L-Glutamine serves as its preferred fuel source, helping provide the resources those cells need to maintain the barrier that supports healthy digestion.
The Recoverer
Helps replenish what training uses
Post-workout recovery support
Glutamine is one of the first amino acids your muscles draw upon during intense physical activity. Replenishing it after exercise helps support the recovery process that follows hard training sessions.
What L-Glutamine support actually looks like
Gut lining gets the support it needs
Glutamine is the primary fuel source for the cells that maintain your intestinal barrier.
Nutrients are better utilized
A well-supported gut lining is better equipped to absorb what you eat.
Recovery becomes more consistent
Replenishes what hard training uses, helping support post-exercise muscle recovery.
Immune health starts with the foundation
Much of your immune system operates within the digestive tract.
What's in it. One Ingredient. Full Transparency.
We don't use proprietary blends. There's one active ingredient in every scoop, and you deserve to know exactly what it is and how much you're getting.
L-Glutamine3.15g per scoop
The most abundant free amino acid in the human body, found in high concentrations in muscle tissue and blood plasma. It's the principal fuel for the enterocytes that line your intestinal wall — supporting tight-junction integrity and repairing the micro-damage that accumulates from diet, stress, medications, and aging. It's also pulled from muscle faster than the body can replace it during hard training, so replenishing it supports the repair cycle that determines how quickly you recover.
Silicon Dioxide
Added only to help the powder flow freely.
Nothing else. No artificial colors. No proprietary blends. No unnecessary fillers. Made in the USA.
After getting my digestion back on track, I wanted something that supported the gut lining itself, not just the symptoms.
My stomach never felt quite the same after a round of antibiotics. L-Glutamine felt like the logical next step.
Sound familiar?
I still train regularly, but recovery isn't as effortless as it used to be. I was looking for something simple that could help.
I wanted one ingredient I could understand, not a label full of things I couldn't pronounce.
How to Take Your L-Glutamine Supplement
One scoop daily.
Take it consistently for gut support, or post-workout to support recovery. The goal is simple: provide your body with a steady supply of the glutamine it uses every day.

Works well with Digestive Enzyme Pro Blend and Colostrum. The Digestive Enzyme helps break food down more completely. L-Glutamine supports the lining that absorption depends on. Colostrum adds another layer of gut barrier support. Each step builds on the one before it.
L-Glutamine Supplement Frequently Asked Questions
A few things worth knowing that people ask before getting started.
I'm already taking the Digestive Enzyme Pro Blend. Where does this fit?
It's the next layer. The Digestive Enzyme Pro Blend supports the breakdown and absorption of what you eat — it prepares your gut to do its job. L-Glutamine supports the structural integrity of the gut lining itself. They do different jobs and work better together than either does alone.
I don't train heavily. Is this still useful?
Yes. The recovery angle is relevant for active people, but the gut lining support is relevant for everyone — particularly adults over 50, people who've taken antibiotics, anyone with a history of digestive disruption, and anyone whose digestion isn't as reliable as it used to be.
What does 'leaky gut' actually mean, and does this address it?
'Leaky gut' is the informal term for intestinal permeability — a condition where the tight junctions between gut lining cells become less effective. L-Glutamine is the primary fuel for the cells that maintain those junctions, so adequate glutamine supports the structural conditions for those junctions to function properly. This isn't a treatment for a diagnosed condition — it's nutritional support for normal gut lining maintenance.
Will this interact with my medications?
L-Glutamine is an amino acid naturally present in most protein-containing foods, and it's generally well-tolerated. If you're managing a serious medical condition or taking immunosuppressants, check with your doctor before supplementing. The full ingredient list is two items.
Why is the serving size 3.15g?
3.15g per scoop is a meaningful, research-supported dose for daily gut lining maintenance. Higher doses (5–10g) are used in clinical contexts for more acute gut repair. For consistent daily supplementation in otherwise healthy adults, 3.15g is an appropriate and efficient dose.
How is this different from the glutamine in my protein powder?
Most protein powders include 1–2g of glutamine as part of their amino acid profile — not as a targeted therapeutic dose. This formula delivers 3.15g of pure glutamine specifically for gut and recovery support, without the caloric load or additional protein.
