SFI Health (formerly Klaire Labs) brings you L-Glutamine Powder, a premium amino acid powder supplement designed to support digestive health, immune function, and muscle recovery.
Glutamine is the most abundant amino acid in the body, playing a critical role in the production of protein, glucose, and glutathione—an important antioxidant.
It serves as the primary fuel for cells in the small intestine, collagen-forming fibroblasts, and immune cells.
Supplementation may help maintain a healthy gut lining, improve immune defences, and aid post-exercise muscle repair, especially during times of stress or increased metabolic demand.
This unflavoured, highly soluble powder delivers 351 g of pure L-glutamine mixes easily with water or juice.
Free from artificial additives, gluten, and common allergens, it’s ideal for those with dietary sensitivities or looking for a clean, hypoallergenic solution.
Whether you're an athlete, managing digestive issues, or simply looking to support overall wellness, this expertly formulated supplement from SFI Health is a trusted daily companion for gut and immune health.
