It's hard to be productive when your stomach's acting up — which is why Jetson's probiotic blends exist. Their Gut Prep formula is especially suited to those who haven't taken many probiotics before, with a focus on laying a foundation of healthy stomach bacteria and microflora to support healthy digestion. The whole blend is vegan, gluten-free, non-GMO, and allergen-free — so anyone can use it to make an improvement in their gut health.
