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.

In season formulation: Mood

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.

L Theanine

Naturally found in green and black tea, L-theanine is like good food for your mood. It promotes relaxation, improves concentration, and promotes the production of serotonin and dopamine to help relieve stress, anxiety, and depression.

Vitamin B12

Vitamin B12 is an important nutrient for good mental health. There’s no such thing as a magic pill, but supplementing B12 along with antidepressant therapy has been shown to greatly improve depressive symptoms.

Lactospore® Bacillus coagulans MTCC5856

Here’s the dirt: This probiotic, found in soil, works some serious overtime. In addition to being a digestive aid – alleviating occasional gas, bloating, diarrhea, constipation, and improving regularity – Lactospore® has also been proven to reduce mental stress.

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.

Lactobacillus plantarum DR7

Besides supporting gastrointestinal health, DR7 is a proven mood-booster. It helps reduce stress and improve cognitive and memory functions, such as basic attention, emotional cognition, and learning.

Lactobacillus paracasei Lpc-37

It’s all about balance — and this probiotic promotes a more even mood, a relaxed state of mind, and better sleep. It has also been shown to reduce the severity of menstrual symptoms in young women.

Vitamin B6

Vitamin B6 plays an important role in regulating and maintaining a good mental-health state. It helps to create neurotransmitters, the critical chemical messengers in the brain, as well as helping to regulate the energy use of the brain.

Why we made this

In all the research on the microbes that live in the human gut, and the latest learnings on what these different probiotic strains can offer, there is one thing research agrees on: the more diverse the strains in your gut the healthier your gut will be. That’s why we created our course of seasonal probiotics. 21 different strains, packed with vitamins and plant extracts, taken over the course of a year will give your gut the diversity it needs, and the health and happiness you deserve.
