L-glutamine powder is a supplement containing glutamine, an amino acid your body also makes. People take it for muscle recovery, gut health, or immune support, but benefits from extra glutamine are not well established for most healthy people.
L-glutamine powder is not proven to increase muscle growth in healthy people who already get enough protein. Strength training, adequate food, protein, and recovery have much stronger evidence for supporting muscle gain.
Mix L-glutamine powder into water or another drink, following the product directions. The typical serving listed here is about 5 g, roughly one medium teaspoon; that serving size is not automatically a recommended daily dose.
There is no well-established best time to take L-glutamine powder before or after a workout. If you choose to use it, take it at a time that fits your routine and follow the product directions.
L-glutamine is used as fuel by cells lining the intestine, but evidence that a powder supplement treats leaky gut in otherwise healthy people is limited. It should not replace evaluation or treatment for ongoing digestive symptoms.
Yes, L-glutamine powder can cause effects such as nausea, bloating, or abdominal discomfort in some people. Stop taking it if symptoms persist, and do not assume that taking more will improve its effects.
Daily L-glutamine powder is not necessary for most healthy people, and long-term use may not offer a proven benefit. If you have kidney or liver disease, are pregnant, or take regular medication, ask a healthcare professional before using it.
Yes, L-glutamine powder and creatine can generally be taken during the same period; there is no well-known specific interaction. However, combining them has not been shown to produce extra muscle or performance benefits beyond creatine alone.
L-glutamine powder is not a proven weight-loss supplement. It does not reliably increase fat burning or reduce body weight, so it should not replace a sustainable eating pattern and physical activity.
No. L-glutamine and glutamate are related but distinct amino acids, with different chemical structures and roles in the body. L-glutamine powder contains glutamine; it is not the same substance as the flavor-enhancing additive monosodium glutamate.

GLYCEMIC INDEX
GLYCEMIC LOAD
Accounts for portion size — a more realistic measure than GI alone.
To burn the 20 calories in 1 teaspoon (medium) (5 g):
🚶
Walking (5 km/h)
🏃
Running (8 km/h)

🏊
Swimming
Times are calculated with the MET equation for a 70 kg adult. Actual burn varies with your weight, age and pace.
L-glutamine powder is a single-amino-acid supplement, rather than a cooking ingredient or a complete protein powder. It has little noticeable flavour, so it is usually mixed into a drink instead of being eaten on its own.
People commonly stir it into water, a post-workout shake or a smoothie; it can also be mixed into soft foods if the product label allows. The nutrition table lists 100 g of protein per 100 g, while a typical serving is about 5 g. Measure servings rather than estimating, and follow the package directions. If you use it alongside protein foods or other supplements, include it when keeping track of your overall intake.
Low
How many vitamins, minerals and how much fiber this food carries per calorie. A high score means a lot of nutrition for few calories.
Low
An EatBetter score computed from fiber, protein and calorie density. A high score means staying full longer on the same calories.
Both scores are calculated per 100 g and do not change with the selected portion. The satiety score is EatBetter's own calculation, not a clinical measure.
