Glutamine supplementation has become synonymous with muscle hypertrophy, reduction in muscle breakdown and increased muscle protein synthesis, but is also linked to less obvious functions such as insulin sensitivity, lactic acid buffering, increased anti-oxidant activity, increased glycogen storage, a key mediator in the citric acid cycle (where ATP is utilized for energy) and improved cell wall integrity.

Supplementing Glutamine may benefit the body when it is otherwise deficient in this amino acid (vegans, vegetarians with low dairy intake), however it may also become depleted in prolonged bouts of endurance exercise meaning Dorian Yates’ Glutamine
could become a key supplement to have in your nutritional armory.
