2022's Top 10 L-Glutamine Supplements

Find out what to look for in a quality L-Glutamine supplement and what to watch out for

L-Glutamine

L-glutamine (often referred to as simply “glutamine”) is an amino acid which plays an integral role in intestinal and digestive health. Many people seek out L-glutamine as a solution for leaky gut or IBS, but L-glutamine has other uses as well.

If you clicked the link to this page, you probably have one of three questions:

  1. Can glutamine improve gut health?
  2. Can glutamine help me lose weight?
  3. Can glutamine improve recovery after exercise?

Continue reading to learn more about L-glutamine and whether it’s right for you.

Can Glutamine Fix My Leaky Gut?

“Leaky gut” is a condition in which the inner wall of the intestines becomes compromised, allowing toxins, allergens, and pathogens to leak through into the rest of the body.

Glutamine is considered to be the most important nutrient for healing leaky gut syndrome. Low levels of glutamine are often found alongside leaky gut syndrome, and supplementation has been shown to improve the integrity of the intestinal wall.

Leaky gut can also lead to poor immune function. The intestines are the largest part of the immune system. Glutamine repairs damaged intestinal lining while also providing a critical fuel source for white blood cells.

Can Glutamine Help Me Lose Weight?

Some studies have yielded promising results with regards to glutamine’s ability to help with weight loss. One study found that glutamine supplementation reduced weight and waist circumference compared to a placebo. Glutamine may also improve glycemic control, good news for people managing diabetes.

Many people who take L-glutamine also report a decrease in their cravings for sweets and sugar which may lead to reduced calorie intake and weight loss.

Can Glutamine Aid Recovery After Exercise?

Muscle soreness can be a struggle, but supplementing with glutamine appears to be one way to alleviate it to some degree.

One study concluded, “L-glutamine supplementation resulted in faster recovery of peak torque and diminished muscle soreness following eccentric exercise. The effect of L-glutamine on muscle force recovery may be greater in men than women.”
