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 NCFM

One of the most researched strains in the microbiome, this is the valedictorian of probiotics. Just a few of its many benefits: it boosts the immune system, regulates insulin, rebalances the gut after antibiotics, lessens gas and bloating, and alleviates the symptoms of IBS.

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 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.

Vitamin D3

Vitamin D is an essential vitamin that’s as vital for your mental health as it is for your physical health. Research has shown that it plays an important role in regulating your mood and decreasing the risk of depression.


This powerful prebiotic helps crowd out bad bacteria, and creates an environment where good bacteria (probiotics) can flourish. Unlike other prebiotics, It works in hours — not days — and won’t cause bloating or discomfort.

How this works: The Gut Immunity & Development Connection

I’m a passionate believer in the role gut health plays in kids’ overall health. So, when I got the chance to develop a probiotic for kids, I was about as excited as a kid after school on a Friday! Its five probiotic strains help with everything from immunity to digestive health, and the boost of vitamin D supports a child’s brain development – but really, all they’ll care about is that it tastes like a yummy orange drink. Which is what makes Jettie such a perfect way to keep your mini-me(s) feeling their best.
