It works!

I’ve never been more regular in my life. I’ve only tried Fit strain, so I can’t speak to if it gives me more energy or if it’s just spring/summer and I’m more active. I have definitely noticed a decrease in my bloat.


It’s been a few months and I haven’t noticed a huge change. I would say so
Far it’s comparable to other probiotics that I have used. The auto shipment is super convenient though.

These are great

I bought these for a few reasons, mostly that my mother had diverticulitis years ago, as well as RA and CKD now, and balancing her response to food is always a challenge. Probiotics always help, but these are better than any others we have tried by far. The fact that they are delivered regularly and I don’t have to worry about them not being in stock or no longer available is fantastic as well

Why didn't I try this sooner??

I had seen a lot of ads for Jetson, so I figured I would give it a shot and try it for a few months and see how it was. But YA'LL- I was so pleasently surprised when I started noticing changes after the first few weeks. I didn't feel gross and bloated all the time, I felt like my digestive system was working a little more smoothly, and I feel more energetic than I used to! I do wish the bottles were smaller, since they seem kinda big for just the 1-month supply, but I'm so glad I started my subscription!

Keeps things moving

I haven’t had much luck with probiotics before Jetson. I’d be gassy, bloated, or both. I definitely needed probiotics, as my normal state was irregular and sluggish. But with Jetson, I feel...normal! Things work and move the way they’re supposed to. Definitely worth it for me.

What Our Customers Say

“Getting to a healthy weight was a major priority for me during the pandemic. I wanted something to give me my best chance. And I love the auto-refill so I don't worry about running out.”
“I was skeptical at first, but I have the worst digestive issues and have been in extreme pain, constipation, IBS, lactose intolerance. I went from pooing 1 time every 2 weeks (sometimes a month) to TWICE A DAY. I got gut prep and fit because I know they really target your tummy. Thank you!”
“I’ve tried several different probiotics over the years is this has been the best I’ve found and at a great price. Foods that might normally cause belly irritation don’t anymore and I’ve been able to maintain my healthy weight.”

What The Experts Say

Healthy gut bacteria can lead to increased energy and the most efficient use of the nutrients in your diet – resulting in less bloating and even weight loss. Fit contains the most studied probiotic strains for weight loss, along with strains studied to reduce bloating and constipation. "
