Our Promise

Jetson’s Immunity probiotic is a powerhouse formula – with 5 diverse probiotic strains, clinically validated to provide strengthened immune support. We took it to the next level and packed Immunity with Vitamin C and Echinacea because when we said we wanted to create the best probiotic for immunity, we meant it.

The specific strains we've added to this formula have been shown to strengthen immune response to viral infection, speed up recovery times and keep upper respiratory infections at bay. Immunity will also continue to support your overall gut health and digestion – just like Jetson always does.

Definitely improved my overall gut health!!

I have struggled with chronic nausea and intestinal discomfort for years, and taking Jetson daily over the last few months has greatly improved my symptoms. Would highly recommend for anyone, whether you have tummy issues or not!

Changed my GI system for the better!

After having my gallbladder removed 20 years ago, I had struggled with IBS-type issues, though I was never diagnosed. Wanting to try a new approach, I read up on probiotics and how they might help me. I started taking the Mood formulation with Gut Prep at the end of 2020, which seemed to make my GI system “regular” for the first time in decades. After the first month on Mood and Gut Prep, I switched to Immunity as part of the seasonal subscription. I have now been taking Immunity for almost 2 months. I’ve continued to have fewer to no stomach/intestinal issues, and I’m staying on Immunity until I can be vaccinated against COVID-19, which will hopefully be mid-April. I have been very cautious, always socially distancing and consistently masking, but Immunity gives me that extra peace of mind during weekly grocery store trips that my immune system is fortified and can protect me from serious illness. Love this product!

Love it!

My husband has been using this blend for only a month, but he immediately noticed a big difference! He normally has a lot of digestive problems but since starting the probiotics he only had 1 day of mild upset, compared to 2-3 times per week of severe upset!

He did still get sick once this month, but he's hoping this blend will help him stay healthier overall this winter.

Great product! Definitely recommend!
