L-glutamine is an amino acid that occurs naturally in the body and also appears in many weight loss aids. L-glutamine is responsible for many functions in the body. Glutamine increases growth hormones in the body, which in turn build muscle and burn fat. Glutamine also keeps the immune system strong, strengthens neurotransmitters in the brain, and protects the liver from disease. When the body is overstressed, it loses glutamine which needs to be replaced.

Ingredients

L-Glutamine

Product Features

Glutamine is often marketed to body builders and professional athletes as it has been shown to play a part in muscle recovery and hydration. There have been conflicting clinical trial conclusions about its effectiveness for this purpose.

L-glutamine often appears in weight loss products due to clinical studies supporting its ability to stimulate human growth hormone in the body. Some products on the market also suggest that L-glutamine can suppress carbohydrate cravings although there does not appear to be scientific support for this claim.

Weight loss products that contain L-glutamine should be examined carefully to assess the L-glutamine content. The referenced studies were conducted using certain levels of L-glutamine. Because the FDA does not regulate weight loss products, there are many on the market today that contain only a trace amount of the substance. This is not enough to be effective in stimulating human growth hormone- or even none at all.

L-glutamine can be purchased as an ingredient in a weight loss formulation or by itself as a white powder. The powder can be mixed with water or juice and is usually taken 2-3 teaspoons twice per day.

While L-glutamine appears to have no serious side-effects, some people may be sensitive to it. If taking the straight L-glutamine powder, users may wish to start at half the recommended dosage until their bodies adjust. Then, the dosage can be increased slowly over the course of a few weeks until the full dosage is achieved.
