Although Glutamine isn’t necessarily THE most important amino acid in promoting muscle growth, it is however the most abundant within muscle. In fact, more than 90% of the whole- body glutamine is found in the muscle, so this gives you some perspective. Leucine is deemed to be the main amino acid for promoting muscle growth and development, however glutamine is considered one of the most important to muscle recovery and regeneration. Glutamine is classified as ‘conditionally essential’ meaning the body is generally capable of producing glutamine, however in people that train hard and often, glutamine levels may deplete enough to warrant external intake i.e. intake via the diet.
Delayed Onset Muscle Soreness (DOMS) is the bane of many an athlete’s life, causing them to limp around with aching muscles the day after an intense bout of physical activity. It is thought that glutamine may reduce the soreness caused by exercise, and in turn help with muscle recovery and growth.
