Your digestive system is home to a complex ecosystem of bacteria known as intestinal microflora. Most of these species reside in the lower intestine, and a study published in the journal Amino Acids suggests supplementing your diet with the amino acid glutamine can beneficially alter this community, but results are limited to mice in a laboratory at this point.
Researchers found that supplementing the diet of mice with 1% L-glutamine for 14 days decreased the abundance of some bacteria and increased others while activating signaling pathways. These actions combined to improve gut bacteria populations in the lower intestine. For a study on the impact of leucine following endurance training, read today's Breaking News at optimumnutrition.com
