There are a lot of things actually, but here are a few highlights: We only use pure and natural ingredients, our probiotics have a long shelf-life and don't require refrigeration, we're 100% made in the USA and we only use strains found in the human gut. We also use a few unique patents and guarantee all our products for a full 60 days. If all that's not enough, we're also the #1 ranked probiotic according to ProbioticsGuide.com!
