Athletech Pure Glutamine 300g

Pure Glutamine is 100% pharmaceutical-grade L-Glutamine - the most abundant amino acid in skeletal muscle and blood plasma. Glutamine is conditionally essential: your body can produce it, but not fast enough to replace what intense training depletes. Supplementing with pure L-Glutamine replenishes your levels post-workout to support recovery, gut health, and immune function.

One ingredient: pharmaceutical-grade L-Glutamine. Each serving is 5g. 300g per tub - 60 servings. No fillers, no carriers, no artificial colours or sweeteners. What's on the label is what's in the bag, nothing else.

Yes. The L-Glutamine is fermentation-derived, not animal-sourced. No capsule shell, no excipients - just pure powder. Suitable for vegans, vegetarians, and those with dairy, gluten, or soy sensitivities.

Pharmaceutical-grade means the ingredient meets the purity and quality standards required for pharmaceutical use - typically 99%+ purity with verified absence of contaminants. Most supplement-grade glutamine on the market is food-grade, which has looser tolerances. Athletech sources pharmaceutical-grade L-Glutamine and backs every batch with a Certificate of Analysis (COA).

Glutamine is used heavily during exercise as an energy substrate and nitrogen carrier. Hard training also triggers a stress response that rapidly increases glutamine utilisation by immune system cells and the gut lining. The result: muscle glutamine levels can drop up to 50% after a single intense session. Your body continues synthesising glutamine, but not fast enough to restore plasma and muscle levels before your next session - creating a cumulative deficit without supplementation.

Glutamine is the primary fuel source for enterocytes - the rapidly dividing cells that line the intestinal wall. These cells have a very high turnover rate and depend on glutamine to maintain the integrity of the gut barrier. Under training stress, when plasma glutamine drops, gut barrier function can be temporarily compromised. Supplementing glutamine supports the gut lining directly, which also improves nutrient absorption from everything else you eat and take.

The research is strongest in two areas: recovery and gut health. Studies show glutamine supplementation reduces markers of muscle damage, decreases DOMS duration, and helps maintain immune function after high-intensity training. The gut health evidence is particularly robust - glutamine is the most studied nutrient for intestinal barrier integrity. Benefits are most pronounced in athletes training at high volume, where depletion is greatest.

5g per day. On training days, take post-workout mixed with water or your protein shake. On rest days, take with a meal. Consistency matters more than exact timing - daily use maintains elevated plasma glutamine levels, which is what drives recovery and gut health benefits. Each tub is 300g - 60 servings at 5g.

Yes - glutamine stacks well with both. Creatine and glutamine operate through entirely different mechanisms (ATP resynthesis vs. nitrogen balance and gut health), so there's no overlap or conflict. With protein, glutamine complements the muscle repair signal your protein is already triggering. Mix all three together post-workout if you like - no timing conflicts.

No. Glutamine is a naturally occurring amino acid - your body uses it continuously. There's no receptor downregulation or dependency risk. Daily, long-term use is both safe and effective. The benefits compound with consistency, not with loading or cycling protocols.

Yes - take it on rest days too. Recovery and gut repair happen primarily during rest, not during training. Keeping plasma glutamine levels elevated on non-training days supports the repair processes that are actively running while you recover. 5g with any meal works fine on rest days.
