GLUTAMINE FOR WEIGHT LOSS
Studies show that glutamine decreases insulin levels. (14) Insulin is a hormone that is necessary for overall health. It's how cells use the sugar in your bloodstream for energy. However, too much insulin leads to severe diseases like diabetes, heart disease, cancer, and obesity.
In fact, glutamine has been shown to reduce the waist circumference in obese women, even without other lifestyle changes like exercise or diet. (15) One of the leading causes of disease is having fat around your organs. In studies with patients with heart failure and type 2 diabetes, glutamine supplementation helped reduce body fat and increase lean body mass. Glutamine supplements can improve fasting blood glucose, reduce body fat and waist circumference, and reduce body weight. (16)
SIDE EFFECTS OF GLUTAMINE
Though glutamine is generally considered safe, some populations should avoid glutamine supplementation. People who have kidney or liver disease should avoid this supplement. Also, some people have had allergic reactions to L-glutamine. Allergic reactions may include joint pain, nausea, vomiting, or hives. Anyone who experiences these reactions should discontinue taking glutamine.
DO YOU NEED A GLUTAMINE SUPPLEMENT?
Glutamine can be ingested through diet. It can be found in plants like beets, carrots, cabbage, and radishes as well as protein sources like beef, chicken, fish, and eggs. If you are eating a healthy, diverse diet, you are probably supplying your body with all the L-glutamine it needs for day-to-day living and short-term exercise.
Supplementation makes sense for people dealing with long-term illnesses or recovering from surgery or trauma. It can help these patients fight off hospital-borne diseases and have a quicker recovery. Because of its ability to assist in muscle building, it can be especially helpful for patients dealing with wasting diseases like cancer or AIDs as well as burn victims.
Glutamine supplements can also be beneficial for athletes who compete in long, strenuous events or have extended training sessions. For those athletes, glutamine can help them build and maintain muscle mass. Because it can help the immune system build and repair cells, it can also be an asset for athletes who find themselves regularly getting ill in the five to seven days following an event. Athletes who are suffering from overtraining may also benefit from glutamine supplementation along with plenty of rest and recovery.
