Bacillus subtilis DE111®

An all-star in many Jetson products, this multifunctional probiotic balances your gut microbiome like a champ. It also prevents the growth of pathogenic (bad) bacteria, helps the body assimilate nutrients, and keeps your poo on point.

How this works: Not Like Other Prebiotics

We developed this prebiotic because so many competitors get prebiotics wrong. Whereas theirs are basically just fiber pills that can cause bloating and discomfort, we formulated ours very differently. Jetson’s Gut Prep gets to work the moment it reaches the gut, founding a colony of good bacteria, while at the same time creating a healthy environment for good bacteria to flourish. Because we know the first step in gut health is building a strong foundation for the body to begin repairing itself naturally.
