"L-Glutamine supplementation promotes a positive nitrogen balance and prevents the loss of muscle. Recent studies have shown that taking just 2 grams of L-Glutamine can increase growth hormone levels by 400%.
The 30g dose studied was associated with a significant reduction in the ratio of Firmicutes to Bacteroidetes in obese and overweight people.
"The finding that L-glutamine promotes changes in the gut microbiota composition provides support for the importance of some nutrients in modulating the intestinal bacterial profile," wrote the researchers in Nutrition . "These changes resembled the weight loss programs established in the literature."
Gut health and obesity
The study adds to emerging body of science supporting the effects of gut microflora on metabolic factors and obesity. The connection between gut microbiota and energy homeostasis and inflammation and its role in the pathogenesis of obesity-related disorders are increasingly recognized.
Animals models of obesity connect an altered microbiota composition to the development of obesity, insulin resistance, and diabetes in the host through several mechanisms: increased energy harvest from the diet, altered fatty acid metabolism and composition in adipose tissue and liver."
