L-Glutamine is the most abundant amino acid in the human body — and one of the first to get depleted when you train hard. Most people get enough from diet at rest, but consistent, high-volume training changes that equation quickly. This is a clean, single-ingredient powder with one job: put back what your workouts take out.
- ✓5g pure L-Glutamine per scoop — no fillers, no proprietary blends, one ingredient
- ✓Supports normal muscle recovery after intense training
- ✓Supports the body’s normal immune response during periods of high physical demand
- ✓Supports normal gut lining integrity

Is this right for you?
✓ For you if:
- ✓You train at high volume (4+ sessions per week) and want to support daily recovery
- ✓You’re a contact sport, endurance, or team-sport athlete in a heavy training block
-
✓You want a clean, single-ingredient amino acid with no artificial sweeteners or dyes
✗ Probably not for you if:
- ✗You have kidney or liver disease — consult your physician first
- ✗You have a history of seizures or neurological conditions — consult your doctor
- ✗You’re pregnant or nursing — consult your physician
- ✗You train casually (2x/week or less) and eat adequate protein — dietary sources likely sufficient
How to use
Mix 1 scoop (5g) in 8–12 oz of water, a protein shake, or any beverage. Unflavored — it mixes cleanly with minimal taste.
Best timing:
- Post-training: ideal window to support recovery
- Before bed: supports overnight recovery and immune function
- Any time of day — consistency matters more than timing
Athletes in heavy training blocks or contact sports may benefit from 10g/day (2 scoops). Consult your physician if considering higher doses.
One container = 60 servings at 5g/scoop.

Frequently asked questions
What does L-Glutamine actually do?
L-Glutamine is an conditionally essentially amino acid — a building block of protein — and the most abundant one in your body. It plays a role in muscle recovery, immune function, and gut health. Under normal conditions your body produces enough. When you’re training hard, demand can exceed what the body can produce. Supplementing helps close that gap.
Will I notice a difference right away?
No — and that’s not how it works. Glutamine doesn’t create an acute effect you’ll feel in the session. What you’re building is a baseline. Give it 4–6 weeks of daily use and evaluate your overall recovery quality.
Is L-Glutamine just for bodybuilders?
Not at all. The research on glutamine includes endurance athletes, team-sport athletes, contact sport athletes, and populations under chronic physical stress. If you train at high volume — any sport, any discipline — it’s worth considering.
Can I take this with protein powder or creatine?
Yes. L-Glutamine mixes well with protein shakes and has no known interaction with creatine. You can combine all three post-training with no issues.
Is it flavored or sweetened?
No. This is pure, unflavored L-Glutamine powder. It has a mild, slightly sweet taste on its own but won’t noticeably alter the flavor of whatever you mix it with. No artificial sweeteners, no dyes, no additives.
Is it safe to take every day long-term?
L-Glutamine is well-tolerated at doses of 5–10g per day in healthy adults. There is no established reason to cycle it. If you have kidney disease, liver disease, or a neurological condition, consult your physician before use.
How is this different from the glutamine in my protein powder?
Most protein powders add 1–2g of glutamine per serving — below the 5g threshold used in sports nutrition research. This product gives you a full 5g dose in one scoop.
Is this product third-party tested?
Yes. We have our products tested by an independent, accredited third-party laboratory to verify purity and quality. Results are available upon request.
