Glutamine is the most abundant conditional amino acid in the body. Results from animal studies suggest that glutamine may help suppress appetite. However, large-scale research trials of humans would be needed to determine if glutamine supplements are useful in treating obesity in people. |
It is widely believed that glutamine may reduce carbohydrate cravings. This thought, however, stemmed out of the fact that it has shown a significant effect on alcohol cravings when treating alcoholism and also on substance abuse. Glutamine amino acid is shown to enhance brain function as it fuels two of the brain's most important neurotransmitters (transmit information within the brain and from the brain to all the parts of the body), glutamic acid and gamma-aminobutyric acid (GABA) and this one reason why it is used as an adjunct therapy to treat alcohol cravings and substance abuse.
However, there have been no studies conducted on the carbohydrate link. But many supplement companies promote it as a source of lowering carbohydrate cravings and thus a potent appetite suppressant. It is important to note that glutamine is not classified as an appetite suppressant or fat burner, such as hoodia, green tea, or other diet pills.
The supplements products may suppress appetite cravings, but the stimulants used in the supplements promote anxiety and nervousness and raise the heart rate in many individuals. These products may be effective for a short time by reducing food intake, but ultimately users of these products return to their former eating habits.
The experience of results, such as reduction of food craving, is solely a subjective one, until further studies are conducted.
