L‑Glutamine 500 mg by SFI Health (formerly Klaire Labs) is a high-purity amino acid supplement designed to help maintain gut integrity, immune health, and overall recovery.
Each capsule provides 500 mg of free-form L‑glutamine in a hypoallergenic, easy-to-swallow format.
It’s especially useful for supporting gut lining maintenance, tissue repair, and immune function after exercise or illness.
As the most abundant amino acid in the body, L‑glutamine plays a central role in producing proteins, glucose, and the antioxidant glutathione.
It serves as a key fuel source for immune cells, fibroblasts involved in collagen formation, and the cells lining your small intestine—making it particularly important during times of physical stress or increased metabolic demand.
Formulated by SFI Health, this supplement is free from gluten, dairy, and common allergens, making it a suitable daily option for those with sensitivities.
