Our Gut Gurus designed Immunity to be the all-around probiotic for your immune system and gut. It has five probiotic strains to boost your gut’s immune system. 70% of your body’s immune system resides in your gut, helping you resist infection and recover from illnesses faster. The strains in Immunity also support the production and function of antibodies and strengthen the lining of your lungs for respiratory health. Plus, it contains vitamin C and Echinacea, which stimulates your immune system’s bug-zapping capabilities even further.

Will Jetson Probiotics work for me?

We're serious about gut health and the impact it can have on overall health. Get the scoop straight from real-life Jetson users whose guts — and lives — have been transformed.


Bacillus subtilis DE111®

An all-star in many Jetson products, this multifunctional probiotic balances your gut microbiome like a champ. It also prevents the growth of pathogenic (bad) bacteria, helps the body assimilate nutrients, and keeps your poo on point.

Lactobacillus acidophilus La-14

This probiotic strain is a serious fighter. As its name suggests, it produces lactic acid, which lowers gut pH, making it more acidic. Harmful bacteria — the ones that cause inflammation in your body — hate that.

Vitamin C

Vitamin C is famous for its immunity-boosting cred, but it does more than just fight colds. It supports your body’s epithelial barrier from pathogens and baddies. It also helps minimize antioxidant damage, allowing the body to repair itself.

Bifidobacterium lactis HN019

Talk about a multitasker: This probiotic strain supports immune cell function, maintains a healthy intestinal barrier, balances the gut microbiome, and reduces gastrointestinal infections.

Echinacea extract

Harness the power of flowers: this pretty plant has been used for centuries to battle colds, plus help with pain relief. Its powerful antimicrobial properties also help fight off everything from the stomach flu to bacterial skin infections.

Lactobacillus rhamnosus GG

Get set for intestinal excellence: This probiotic strain maintains a healthy intestinal barrier by adhering to the mucosal cells in your intestine, helping it absorb nutrients from food — and keeping your immune system healthy.

Bifidobacterium lactis Bl-04

Get your gut right, courtesy of this iconic probiotic. It supports digestive health, decreases occasional diarrhea, and strengthens immune response (especially when it comes to allergies and nasal congestion).

How this works: The Gut Immunity Connection

You have probably heard the stat that 70% of your body’s immune system resides in your gut. Using the latest research, I was able to pick the individual probiotic strains that best support this critical function of the gut. Given the importance of immunity as we get back out into the world after the pandemic, I also boosted it with Vitamin C and Echinacea to help your body resist infection and recover from illnesses faster.
