Our Story

Dr. Grace's and The Gut Institute’s revolutionary probiotic formula, Bifido Maximus, was created with a healthy gut in mind so your body can function optimally and you can live your best life - physically, mentally and emotionally. We’re all doing our best to be healthy and gut health is one of the most important cornerstone’s of overall health. 



The Bifido Maximus has been hailed the fountain of youth! It has the highest strength in the industry containing species that are eradicated in modern life. The strains found in this probiotic blend are the same strains found in the guts of octogenarians (people in their 80s). 


It’s also best for weight and fat loss! Lactobacillus gasseri is shown to support weight and fat loss and Bifido Maximus has one of the strongest potency and concentration of L. gasseri on the market. It’s also a SIBO-safe formula because it is Streptococcus-free, histamine-species-free and D-lactic-acid-free species. 


We care about your poop, your health and the planet. The Bifido Maximus is formulated by Dr. Grace herself and all of our products are manufactured in the USA.
