AOR AOR - L-Glutamine 5000mg, 450 grams

AOR L-Glutamine Powder - Supports immunity and digestion after periods of physical stress. L-glutamine is the most abundant free amino acid in the body. It is critical for many essential functions including the optimal operation of the kidneys, pancreas, gall bladder, liver, intestines and the brain. L-Glutamine supports the immune system and is a precursor for glutathione, one of the body’s most important antioxidants. Those who are under undue stress, suffer from leaky gut or have weakened immunity may benefit from L-glutamine; as well as those seeking to increase their muscle mass and improve exercise recovery.

Why people keep reordering it

Clean fuel: Quality protein and greens without the junk.
Easy to mix: Blends smooth into water, milk or a smoothie.
Recovery and everyday nutrition: Supports muscle, energy and filling dietary gaps.

Best suited to: training hard and want gut and recovery support, dealing with a sensitive or irritated gut, want a plain, stackable amino acid without extras.

What the research supports

One scoop provides 5 grams of L-glutamine, taken once daily on an empty stomach. The 450-gram tub lasts about 90 days.

Studies use 5 to 10 grams a day.

Gut lining (evidence: moderate, from human clinical trials, mechanistic studies): Glutamine is the amino acid gut-lining cells burn first for fuel. Supplying more may help that barrier hold up under physical stress or illness, though most of the strong evidence comes from clinical, higher-dose settings.
Exercise recovery (evidence: mixed, from randomized controlled trials, small human trials): During and after hard training, gut cells and immune cells compete for the body's glutamine supply, which can leave less for repair. Trials on extra glutamine show mixed effects on soreness and immune markers.
Antioxidant capacity (evidence: limited, from mechanistic studies, animal studies): Glutamine is one of the raw materials your cells use to build glutathione, the body's main internal antioxidant. Whether oral supplementation raises glutathione levels in healthy people is unclear.

Is it right for you

Worth it if

Training hard and want gut and recovery support: 5 grams of glutamine is a standard single dose used in exercise recovery research, and it replenishes an amino acid that gets depleted during intense or prolonged training.
Dealing with a sensitive or irritated gut: Glutamine is the primary fuel source for the cells lining the intestine, and low-dose supplementation has been studied for supporting that barrier after stress or illness.
Want a plain, stackable amino acid without extras: This is unflavoured single-ingredient glutamine with no fillers, so it mixes into shakes or water without changing the flavour of anything else you're taking.

Look elsewhere if

Looking for a pre-workout or energy boost: A pre-workout with caffeine, or carbohydrate before training. Glutamine is a conditionally essential amino acid taken on an empty stomach, not a stimulant.

What to expect

Nothing is felt immediately. If you're using it for gut comfort or recovery, most people give it several weeks of consistent daily use before judging whether digestion or recovery feels different, since it works by supporting cell repair processes rather than producing a sensation.

How it compares

Compared with a glutamine-containing recovery blend with BCAAs added: This gives you a clean, adjustable dose of glutamine on its own, so you can pair it with whatever else you're already taking without duplicating ingredients. The tradeoff: You don't get the branched-chain aminos or electrolytes some blends include, so it does one job rather than several.
Compared with capsule-form glutamine: Powder lets you easily scale the dose up to 10 or 15 grams by adding scoops, which capsules make cumbersome. The tradeoff: It has to be mixed with water and has a mild taste some people notice, unlike swallowing capsules.
