Seasonal Probiotics Subscription (Pay Monthly)
To achieve optimal gut health, your probiotic strains must be:
- Diverse
- Alive
- Clinically proven, never generic
In order to hit these three points, you have to rotate the strains you take frequently, make sure those strains are fresh, and research the studies tied to them. Who has time for that much work? We do. Jetson’s seasonal subscription is the only brand doing the work for you.
Subscriptions renew automatically every month.

First of all, let us tell you why seasonal is so important. Research proves that to keep your gut at its healthiest, you need a variety of strains. It turns out, that’s kind of a pain to do on your own. So we do it for you, switching up our formulations so that you’re getting strains that are clinically studied to meet your needs each season.
Subscribing to our program means setting it and forgetting it. We automatically rotate formulations and deliver what you need, when you need it. Fit in summer, Mood in fall, Immunity in winter, and Outside in spring. Each of these steps in the program include strains to optimize your wellbeing (like supported immunity in the winter and allergy defense in the spring).
Here is the schedule of our seasonal rotations:
FIT = Summer (orders placed Jun 20 - Sep 19)
MOOD = Fall (orders placed Sep 20 - Dec 19)
IMMUNITY = Winter (orders placed Dec 20 - Mar 19)
SKIN = Spring (orders placed Mar 20 - Jun 19)
Everyone's a little different. The first thing you will likely notice is more regular and better bowel movements...these can come days or up to 8 weeks after you start taking Jetson.
Other immediate benefits we've heard are better sleep, more energy, and better hair (seriously). But beyond that, science is just discovering how important a healthy gut is to overall health.
If you’re already healthy, you might not notice life changing differences. Yeah, you can’t de-bloat if you weren’t bloated in the first place (fine, brag about it). But it’s kind of like skincare. Even if you have radiant skin, you still take care of it because you know it’s working for you.

Well, how much time do you have exactly? We could go on and on, but in the interest of time, here’s what you need to know:
We Rotate Our Strains: We’re the world’s only seasonal probiotic. We're the only brand to rotate your formulations – whether you choose to do it on our time or yours – which is proven to maximize gut health.
We Use Clinically Validated Strains: See those numbers behind each strain that’s listed on your bottle? That means the strains aren’t generic– they’re the numbered strained used in scientific studies, not variants. Using the exact, named strains means we can claim their benefits.
We’re Convenient: Set it and forget it. Jetson is direct-to-consumer, which means your subscription leaves our facility and goes straight to you – quickly and consistently every month.
Still have questions? Contact us.
Although we typically encourage you to keep your probiotics stored anywhere below 77ºF (no fridge necessary), we are aware that Jetson packages might be sitting on some 100+ degree porches from time to time. So we did what we do best – conducted a study. Q Labs, the leading Microbiology & Chemistry Product Analysis, studied Jetson for 10 days in 100ºF (at 65% humidity). The number of CFUs present after 10 days exceeded the amount on the label. Meaning that you get all the bacteria you need.
As long as you’re not leaving your probiotics to bake in the hot sun for weeks at a time, your probiotics will be just fine.
Fit, Immunity and Skin don't contain any dairy or soy.
One of our highest studied strains in Mood was grown on dairy. So while the pill you’re taking contains no dairy or animal products, dairy was involved in the growing process. In the facility that this strain is grown, they also process probiotics grown on soy. Every strain is grown in a completely separate and controlled environment, but because the facility does process strains that have been grown on soy, we have to put it on the label. There is no soy in the actual product.

What You'll Get
Our seasonal subscription includes: monthly deliveries of fresh probiotics with a different formulation every standard season: Fit for summer, Mood for fall, Immunity for winter, and Skin for spring.
Each formulation contains strains that address common seasonal concerns, because if you have to rotate your strains they might as well work in your favor. Right?

Immunity was created to enhance your immune system to limit the duration and intensity of colds.*

Skin rejuvenates your skin from the inside out, giving you a glow that no amount of topical treatments and cosmetics can replicate.*

Get lean with fit. Have the energy you need to make the most of summer days, with strains that debloat and encourage weight loss.*

Mood is formulated to reduce anxiety, improve your mood and support your immune system as the days get shorter and colder.*
What’s In Season: Immunity For Winter
Allow us to introduce you to Immunity: a probiotic for (ding ding ding!) a healthy immune system. This formulation lowers your risk of catching a cold by strengthening your overall immune response, supports respiratory health and eases inflammation related to chronic inflammatory conditions. No one wants to be that guy coughing at the grocery store this year… Cover your bases with Immunity.
Why We Made This
The gut is the body’s control center. That’s why people call it the second brain. An unhealthy gut can lead to poor digestion, weak immunity, chronic inflammation, bloating, low energy and poor sleep, to name a few.
A tighter gut lining combats heart disease, inflammatory conditions and autoimmune disorders.*
No one wants a leaky gut. Probiotics enhance nutrient absorption and increase regularity.*
Probiotics positively enhance your health-span, not just lifespan.*
70% of the immune system is in the gut. Jetson's studied strains are clinically proven to reduce sickness.*
Our specially formulated capsule is designed to withstand stomach acid - keeping the bugs alive until they reach the intestinal tract where they’re needed.
We also leave out preservatives and unnecessary sugar to keep our products as boring as you’d want your probiotic to be.
Like most things in life, quality trumps quantity. Probiotics are no different, which is why we don’t play the “who has more CFUs” game. Here’s why: many brands with high CFU counts broadcasted on the bottle are using generic, dead, ineffective strains. Our strains are studied and fresh - which means they work.
