From the time the GI Relief supplement is shipped, there is generally 6 months of shelf life remaining.

The FMT Gut Restore Supplement is lyophilized fecal microbiota transplant (FMT) material from our rigorously screened donor cats and dogs that is enclosed in an enteric-coated capsule. Learn more about the donor screening process..

Slight variations in diet, hydration status, or activity of donors can result in capsules that are slightly different colors from one another. All of our donors undergo extensive screening and testing, making sure that the healthy native microbes are present and within our healthy reference ranges.

Due to the high efficacy of the upper GI tract for eliminating bacteria, the FMT material should not be removed from the enteric-coated capsule. The capsule prevents dissolution in the acidic pH of the stomach, allowing the bacteria in the FMT material to reach the intestines in high numbers. Removing the material from the capsule will significantly decrease the efficacy of this therapy.
