Our products are vastly different from 98% of the probiotics on the market. Just Thrive Probiotic & Antioxidant is comprised of four strains of Bacillus spores that naturally survive the harsh gastric system. No refrigeration is necessary. In fact, our strains are so hardy you can freeze them or bake with them up to 455 degrees. We are one of the only probiotic companies with profound research and studies, and are currently in 12 human clinical trials. We even have a published study showing the strains in Just Thrive beginning to heal leaky gut in only 30 days with no change in diet. It is our passion to help as many people as we can to take control of their health and heal naturally - Non-GMO, Sugar, Salt, Gluten, Nut and Dairy Free!
