Glutamine is a conditionally essential amino acid, meaning the body usually produces it, but during stress, illness, or intense physical exertion, dietary intake becomes crucial. It serves vital roles in:
-
-
Supporting gut health by fueling intestinal cells and maintaining the integrity of the gut barrier
-
Strengthening immune function as a primary energy source for immune cells, aiding recovery and defense
-
Promoting metabolic balance through nitrogen transport, acid-base regulation, and glucose metabolism
-
Assisting in muscle recovery by reducing exercise-induced stress and preventing muscle breakdown
Rich dietary sources of glutamine include: beef, chicken, fish, eggs, dairy (yogurt, milk), tofu, beans, cabbage, and spinach.
Low glutamine levels may weaken immune response, impair gut health, slow recovery from illness or injury, contribute to muscle wasting, and disrupt metabolic stability.
