GI Sustain™ by Metagenics – Gastrointestinal Support Powder for Gut Health
GI Sustain™ by Metagenics is a comprehensive gastrointestinal support powder formulated with prebiotic nutrients, readily digestible macronutrients, amino acids, vitamins, and minerals. It is designed for adults seeking convenient nutritional support for digestive function, intestinal cells, and a balanced gastrointestinal environment.
This rice-based formula supplies protein, carbohydrates, healthy fats, dietary fiber, and targeted nutrients in a drinkable powder. Its combination of prebiotic fiber, rice protein, and supplemental amino acids makes it especially useful for individuals who prefer a broad nutritional formula rather than a single-ingredient digestive supplement.
Key GI Sustain Benefits
- Provides comprehensive digestive health support with prebiotics, amino acids, and essential nutrients.
- Helps nourish intestinal cells with L-glutamine and readily available macronutrients.
- Supplies rice protein with supplemental amino acids to support daily protein intake.
- Promotes the growth of beneficial intestinal bacteria through isomalto-oligosaccharides.
- Includes vitamins and minerals that support normal energy metabolism and overall wellness.
How GI Sustain Works
GI Sustain combines complementary nutritional components that support the gastrointestinal tract in several ways. Isomalto-oligosaccharides act as prebiotic nutrients that help nourish beneficial bacteria already present in the digestive system. Supporting these microorganisms assists with maintaining a balanced intestinal environment and normal digestive function.
L-glutamine provides an amino acid used by rapidly dividing cells, including cells of the intestinal lining. Rice protein concentrate and added amino acids supply building blocks needed for normal tissue maintenance, while apple fiber contributes additional dietary fiber. Olive oil and medium-chain triglycerides provide concentrated energy sources, and the formula's vitamins and minerals help support nutrient metabolism. Together, these ingredients provide broad intestinal health support in an easy-to-mix powdered format.
Key Functional Ingredients Include:
- Isomalto-oligosaccharides: Prebiotic carbohydrates that promote a supportive environment for beneficial intestinal bacteria.
- L-Glutamine: An amino acid that helps nourish intestinal cells and supports normal gastrointestinal tissue integrity.
- Rice Protein Concentrate: Provides readily digestible protein supported by supplemental amino acids.
- Apple Fiber: Contributes dietary fiber to support normal digestive function.
This rice-based nutritional powder is non-GMO and gluten-free. Metagenics also provides an introductory option for highly sensitive individuals, allowing the serving amount to be gradually increased during the first several days as tolerated.

Frequently Asked Questions About GI Sustain
What are the benefits of GI Sustain?
GI Sustain provides broad nutritional support for the gastrointestinal system by combining prebiotic carbohydrates, rice protein, dietary fiber, amino acids, vitamins, minerals, and energy-providing fats. Its isomalto-oligosaccharides help nourish beneficial intestinal bacteria, while L-glutamine supports the nutritional needs of intestinal cells. The formula also supplies 13 grams of protein and 5 grams of dietary fiber per serving. These complementary nutrients make it suitable for people seeking a comprehensive powder that supports digestive balance, intestinal function, and daily nutritional intake.
Who should take GI Sustain?
GI Sustain is formulated for adults who want comprehensive gastrointestinal and nutritional support in a powdered drink. It may be appropriate for people seeking prebiotic nutrients, supplemental protein, amino acids, vitamins, minerals, and fiber within one formula. Because it contains meaningful amounts of several nutrients, including preformed vitamin A, its use should be discussed with a healthcare practitioner, particularly during pregnancy or when combining it with other fortified foods or supplements. Highly sensitive individuals may begin with a reduced amount according to the manufacturer's directions.
Are there any side effects of taking GI Sustain?
Individual responses to powdered nutritional formulas and prebiotic ingredients can vary. Some people may notice temporary digestive changes when increasing their intake of prebiotic carbohydrates or fiber, especially when beginning with a full serving. Metagenics recommends that highly sensitive individuals consider starting with one-half to one scoop twice daily for the first three to four days before progressing to the full amount. Stop using the product and consult your healthcare practitioner if it causes persistent discomfort or an unexpected reaction.
How does GI Sustain support overall health?
GI Sustain supports overall health by supplying a combination of macronutrients and micronutrients used throughout the body. Protein and amino acids provide building blocks for normal tissue maintenance, while carbohydrates and fats supply dietary energy. Its vitamins and minerals assist normal metabolic, antioxidant, immune, and cellular functions. Prebiotic isomalto-oligosaccharides help maintain a supportive environment for beneficial intestinal bacteria, and L-glutamine helps nourish intestinal cells. This integrated approach connects digestive nutrition with broader daily nutritional and wellness needs.

GI Sustain
GI Sustain makes my stomach feels great. I drink it first time in the morning and it takes away the light emptiness but doesn’t make me feel ill like I feel when I drink coffee first thing.
