Why We Chose This
Your gut lining and immune cells are voracious glutamine consumers, especially when you're training hard or under stress. During these periods, your body's demand for this amino acid outpaces what you can synthesize on your own. Thorne's L-glutamine formulation delivers 500 mg per capsule in a clean, straightforward dose. The research supporting glutamine for muscle recovery and intestinal barrier function is solid, making this a practical choice for anyone looking to support both athletic performance and digestive resilience without unnecessary additives.
