Product education

L-Glutamine: Foundational Fuel for Gut and Muscle Health

L-Glutamine by SFI Health provides a pure, free-form source of the most abundant amino acid in the body. As a conditionally essential amino acid, L-Glutamine serves as the primary energy source for intestinal cells and is a major component of muscle tissue. During times of physiological stress, illness, or intense exercise, the body’s ability to produce enough glutamine may be compromised, making supplementation beneficial for supporting a healthy intestinal lining, robust immune function, and lean muscle mass.*

How It Works: Nourishing Cells from the Inside Out

This formula provides a key building block that supports multiple systems throughout the body, from digestive integrity to immune readiness.*

Primary Fuel for the GI Tract
The cells of the small intestine have a high turnover rate and require immense energy to function. L-Glutamine is their preferred fuel source, helping to support the integrity of the gut lining. A healthy gut lining is crucial for proper nutrient absorption and for preventing intestinal permeability, which in turn supports healthy immune function.*

Muscle and Immune Support
Stored in high concentrations in muscle tissue, glutamine is essential for protein synthesis and the formation of other vital compounds like glutathione, a master antioxidant. By providing this key amino acid, this supplement helps support the maintenance of lean muscle mass and provides fuel for the cells of your immune system, ensuring they are ready to respond.*

  • Supports the health and integrity of the GI tract lining*
  • Serves as the primary energy source for intestinal cells

  • Aids in the maintenance of lean muscle mass
  • A clean, hypoallergenic, free-form amino acid
