Gut Prep

Gut Prep cannot be purchased alone. To buy Gut Prep please first add a Seasonal Probiotic to your cart

On your mark, get set, Gut Prep.

Gut Prep is Jetson's take on prebiotics for adults. Consider prebiotics the starting point for a healthy stomach—they are the non-living, non-digestible ingredients that feed all that good bacteria your probiotics are bringing you. Because prebiotics and probiotics work hand in hand, we recommend taking Gut Prep prebiotic capsules together with your first month of seasonal probiotics.

Why We Made This

The gut is the body’s control center—it’s often called the second brain. An unhealthy gut can lead to poor digestion, weak immunity and inflammation. Jetson gives you the probiotic boost needed to increase immunity, reduce bloating and digest the most nutrients from your food.

The Blend

Gut Prep is a vegan prebiotic that uses a novel bacteriophage, causing your body to use the bad bacteria living in your gut as food for the good ones. Simultaneously, Gut Prep prebiotic capsules each place a starter dose 1B CFU of rugged, studied probiotics right to your gut.


If you're new to probiotics, or if processed foods have done serious damage to your gut, we highly recommend taking Gut Prep prebiotic capsules in conjunction with your first month of seasonal probiotics.

Bacillus subtilis

Clinically shown to repopulate levels of good bacteria and promote healthy intestinal balance

Jetson Gut Prep: the Start of a Healthier Stomach

On the Cutting Edge

Gut Prep is a vegan prebiotic that uses a novel bacteriophage, causing your body to use the bad bacteria living in your gut as food for the good ones. We don't use massive amounts of starch or fiber like other prebiotic capsules, because we've heard they cause uncomfortable bloating and gas.

Solid Glass Bottles

Our bottles are reusable, recyclable, and protect the pills from moisture.  Nature knows best – and glass is best.

Proprietary Capsule Delivery

Our specially formulated capsule is designed to withstand stomach acid—keeping the bugs alive until they reach the intestinal tract where they’re needed.

No Lame Stuff

No allergens, vegan, non-GMO, no preservatives and no sugar. Our products are as boring as you’d want your probiotics to be.
