Q.How does GI Sustain™ Medical Food compare to other products or approaches?

This formula contains only natural ingredients for a safer approach, and has been clinically reviewed at the FMRC.
Q.How does GI Sustain™ Medical Food work?
It's enhanced with specific nutrients—including rice protein developed through a patented manufacturing process—and targeted ingredients to nutritionally manage gastrointestinal health, including support for intestinal lining and immune function (through a healthy bacterial balance). Rice protein has a lower allergenic potential than many common animal or vegetable protein sources, which (along with careful formulation and manufacturing) helps make this product suitable for dietary elimination programs. This product is formulated for use with modified elimination diet (to reduce dietary chemicals and common foods with allergenic potential) to offer a higher level of support for better results.
Q.How long is GI Sustain™ Medical Food typically recommended?
A typical introductory program is 25 days (with a modified elimination diet) to evaluate progress. Some people may report positive changes in just a few weeks, but individual results may vary. This product may also be recommended for long-term support. For best results, follow your health care professional's guidelines.
Q.Who would benefit from GI Sustain™ Medical Food?
People with leaky gut syndrome , a condition that can lead to increased permeability of the gastrointestinal (GI) lining. This creates an opportunity for environmental toxins , undigested food, microbes, and waste to "leak" through the body's protective GI immune system.
Q.Why is GI Sustain™ Medical Food safe?
Medical foods must contain ingredients that are generally regarded as safe (GRAS) or FDA approved, and Metagenics continually evaluates formula ingredients in concert with current nutritional research for optimal safety and effectiveness. Plus, Metagenics' manufacturing facility has 3 certifications for good manufacturing practices to ensure the highest quality.
