Fortify your muscles and your mind every day with the pure amino acid nutrition of Swanson L- Glutamine! A favorite among fitness buffs, glutamine is the most abundant amino acid in skeletal muscle tissues, where it works to promote strength and endurance—but that's not all it does. Glutamine's unique molecular structure allows it to pass through the blood/ brain barrier to nourish vital brain tissues. Once in the brain, glutamine is converted into glutamic acid, the base material for key neurotransmitters needed for healthy mental and nervous system function.

Glutamine also provides fuel for immune cells through its activity in the gut where it may help maintain intestinal barrier function to promote GI tract integrity. Since a solid 70% of your immune system stems from your gut, keeping your digestive system happy is a win for your immune function as well. Swanson L-Glutamine Powder mixes easily into juice or water and delivers a potent 5 g per scoop.
