Product education

GastroThera™: Comprehensive Support for GI Tract Health*

GastroThera™ by SFI Health is an extensive, glutamine-rich prebiotic formula designed to provide comprehensive support for the entire gastrointestinal tract. This formula addresses the high energy requirements of the intestinal lining, supports the structural composition of GI cells, and promotes a healthy balance of microorganisms. It’s a foundational supplement for nutritive support of GI function, often used to complement probiotic supplementation.*

How It Works: Fueling and Protecting the Gut

This formula works through multiple pathways to nourish and support a healthy and comfortable GI tract, from cellular energy to the mucous lining.*

Glutamine for Intestinal Fuel
The amino acid L-Glutamine serves as the primary fuel for the cells of the intestinal lining. GastroThera™ provides a potent dose to help meet the high energy demands of the GI tract, especially during periods of physiological stress, while also assisting the body in processing ammonia.*

Prebiotic Fiber & Mucous Support
Soluble fibers from Acacia and Inulin act as prebiotics, which are readily fermented by beneficial bacteria in the gut. This process produces short-chain fatty acids that support colonic cell function and assist in water absorption. To complete the formula, N-Acetyl-D-Glucosamine helps form the protective intestinal mucous secretions that are crucial for tissue health and the smooth passage of food.*

  • Provides extensive support for the entire GI tract*
  • Features high-potency L-Glutamine to fuel intestinal cells
  • Includes prebiotic fibers Acacia and Inulin for microorganism balance
  • Supports the production of protective intestinal mucus*
  • A glutamine-rich, prebiotic formula to support GI and immune function*
