Intestamine capsules, supplied by Douglas Laboratories®, is a unique and convenient dietary supplement formula for gastrointestinal support, providing significant amounts of L-glutamine, an amino acid that is important in maintaining normal structure and function of the gastrointestinal tract; NutraFlora® FOS, which selectively provides nourishment for beneficial intestinal bacteria; acacia fiber, which is fermented into short chain fatty acids for the lower intestine; and N-Acetyl-D-Glucosamine, which is used as a structural component of intestinal mucous secretions.


Glutamine. The amino acid glutamine plays a key role in the metabolism, structure, and function of the entire gastro-intestinal (GI) tract, and its extensive immune system. Glutamine is perhaps the major energy source for intestinal cells, and under conditions of physiological stress the GI tract benefits greatly from extra dietary glutamine.

Glutamine is the most abundant amino acid found in blood, and is a vehicle for nitrogen transport. Glutamine-consuming tissues, such as the GI tract, the liver and the immune system, use glutamine for the synthesis of nucleotides, proteins and amino sugars. Glutamine carries potentially toxic ammonia to the kidneys for excretion, and participates in maintaining normal acid-base balance.


This product may be a useful dietary supplement for those who wish to provide nutritional support for a healthy GI tract.


Six capsules contain:

  • L-Glutamine – 3,750 mg
  • NutraFlora® FOS (Fructooligosaccharides) – 187 mg
  • Acacia Fiber (soluble dietary fiber) – 375 mg
  • N-Acetyl-D-Glucosamine (from crab and shrimp) – 187 mg

Suggested Use

Adults take 6 capsules daily or as directed by one of our health coach professionals. Individuals with GI conditions should consult a health care professional for appropriate use of Intestamine® capsules for their nutritional support. For best results, take with cold or room-temperature foods or liquids. Do not take with foods or liquids that are hot or highly acidic.

Intestamine can be taken regularly, and can be combined with probiotic dietary supplements, such as Douglas Laboratories’ Multi-Probiotic 15 Billion or similar products delivering beneficial living bacteria.
