L-Glutamine

Glutamine for muscle recovery

Glutamine is popular with gym-goers, but studies in healthy, well-fed athletes show little or no benefit for muscle growth, strength or recovery. Your body makes glutamine and gets more from protein foods, so if you already eat enough protein, extra glutamine is unlikely to make a noticeable difference. Protein intake, creatine and good sleep have much stronger evidence.

Glutamine for gut health

Because gut cells use glutamine for energy, it is often promoted for "leaky gut" and digestive problems. Some small studies suggest benefits for certain people, such as those with irritable bowel syndrome after an infection, but the evidence is limited. In hospitals, glutamine is sometimes used for patients with serious illness or burns under medical supervision, which is different from everyday supplement use.

How people take it

L-glutamine powder is usually taken at about 5 g a day, mixed into water or a shake. It has almost no taste. Capsules are convenient but you need several to reach the same dose.

Safety

Glutamine is generally well tolerated at common doses. People with liver disease, kidney disease or a history of seizures should not take it without asking a doctor, and the same applies during pregnancy and breastfeeding. As with any supplement, choose a third-party tested product.

Glutamine price in Bangladesh

Unflavoured glutamine is a simple, single-ingredient powder, so compare products by price per gram and testing seal rather than branding. Powder must be kept tightly sealed and dry, especially during the monsoon.

If gut symptoms are what you want to treat, see a doctor first: bloating, pain or changes in bowel habits can have many causes that need proper diagnosis, and glutamine should not delay that.

Glutamine is not suitable for children unless a doctor recommends it, and it should not replace a varied diet with enough protein.
