Glutamine is a vital amino acid that is required by every muscle in the body, and is one of the most important building blocks in forming the proteins that maintain cellular health and tissue repair.
Although research on the health effects of taking L-glutamine supplements is fairly limited and often dated, some studies suggest that L-glutamine supplements may offer certain health benefits.
Generally, Glutamine is marketed as a supplement used for muscle growth in weightlifting, bodybuilding, endurance, and other sports such as long distance running or cycling, and can help to reduce the incidence of cramps caused through repetitive strain. Because Glutamine can help in this regard, it is also recommended for elderly people who suffer from cramps and regular muscle pain as a natural alternative to chemical pain killers.
Some reported that L-glutamine may be beneficial to people undergoing cancer treatment. In a more recent study (published in the journal Colorectal Disease in 2007), researchers found that L-glutamine supplementation decreased post-operative complications and reduced the duration of hospital stay among patients undergoing colorectal surgery for cancer. The study involved 109 patients with colorectal cancer.
Given these concerns, it’s also important to seek professional advice prior to using L-glutamine supplements.
