Shelf-Stable Probiotics – Taking random assortments of probiotics is not the answer, and can leave users worse off than where they started. We bring colon support through a patented, clinically backed, shelf stable probiotic, Lactospore (Bacillus coagulans MTCC 5856). It can survive gastric secretions and bile of the upper digestive tract and reaches the intestines safely to exert its benefits. Our goal is to revive and restore your natural flora, not to confuse it more.
Full-Spectrum Digestive Enzymes – Designed to jump-start digestion in the upper stomach, our comprehensive blend works synergistically with the body’s natural digestive enzymes to help ensure nutrient availability. Our blend is particularly beneficial for those on higher protein diets. This is not a random assortment of enzymes, but a perfectly curated blend that we have seen success with in our products for nearly 10 years.
PepZin GI Zinc Carnosine – This special form of zinc is absorbed directly on the stomach lining. Numerous clinical trials show it can improve symptoms of GERD, GI discomfort and digestion. Its high absorption makes it a great immunity booster as well. In terms of digestive health, acidity regulation is key, especially for those with leaky gut and gastritis.
Prebiotic Fiber – 3 grams of prebiotic oat fiber to support daily regularity and colon health. Many prebiotic fibers can actually lead to more gas and bloating, not less! We use the perfect amount of oat fiber to support bowel regularity, without making bloating worse. We avoid prebiotic fibers like inulin and chicory root, which cause intense gas and bloating. Our prebiotic solution has users feeling relieved.
L-Glutamine – 5g of L-Glutamine is contained in every serving of Complete-GI to support gut lining and optimal GI health. For those looking for leaky gut repair or gastritis support, glutamine should be part of your foundation. Supporting your natural gut lining is essential for gut repair as a whole.

Good mixture
I love that it contains probiotics, prebiotics, and glutamine all in one. Definitely worth the money. No taste at all. Helps with bloating and digestion.

Does not dissolve
Product does not dissolve and sinks to bottom. Makes it hard to drink.

Probiotics and L-Glutamine
The main reason I got this was because it has L-Glutamine and probiotics/prebiotics. The product does come with a measurement scoop which made it easy to use the correct amount. The powder itself is suppose to be unflavored. However, adding it to juices did alter the flavor for me significantly enough that I wouldn’t try it again or recommend it that way. When mixed in coffee, it was easier for me to drink. The powder itself also doesn’t mix very well so can be felt when drinking. I do like this product for what it provides. However, I wish it was easier to mix and even less taste.
