Do vegans need glutamine supplements?

Vegans may benefit from supplementing with glutamine, especially if their overall protein intake is low. While glutamine is abundant in skeletal muscle and marketed for recovery, its primary benefits lie in gut health and immune function. Vegans, who may struggle to meet their protein needs, can find supplementing with amino acids, including glutamine, beneficial for immune and gut health, particularly because glutamine aids in gut repair. Therefore, it can be a valuable addition to a vegan diet to support these functions and make up for potential deficiencies in protein intake 1.
