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 chronic inflammation. Only Jetson's seasonal formulations give you the probiotic boost needed to increase immunity, help you enjoy the outside, and digest the most nutrients from your food. Read more on gut health here.

It's a Program - Not a Pill

Jetson is the only probiotic in the world to change its formulations each season to match what our bodies need. Microbiome diversity is the key to gut health and Jetson’s year-round customized program takes the guesswork out of being healthy.

The Blend

Jetson Outside’s proprietary formulation is designed to help you enjoy the outside knowing it’s allergy and activity season. No probiotic can legally claim to fight allergies – but Jetson has two exciting clinical strains that are studied to reduce the effects of seasonal allergies.

Breathe Easier - It's Spring

Jetson Outside has 8 researched, validated, and named probiotic strains that have shown to have positive impacts on the immune system, respiratory system and gut health – which directly contributes to overall health.

Jetson Outside: the Best Probiotic for Spring

20B CFU (Colony Forming Units) per pill

We don’t play the ‘bigger is better’ CFU count wars. Our probiotic bugs are specific, studied and effective. Most other probiotics with more CFUs are generic, dead and pointless. Sure, it costs us more - but that’s our style. Read more here.

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.
