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.

What’s the difference between probiotics, prebiotics, and enzymes?

Each of our products promote a healthy digestive environment and improved overall gut health. Our prebiotics eliminate harmful bacteria so beneficial bacteria can flourish. Probiotics are live bacteria that restore gut balance and support overall gut health. Enzymes speed up the breakdown of food for better nutrient absorption.

What can I expect from taking a probiotic?

When you start taking probiotics, you’re introducing a host of beneficial microbes that will quickly begin to multiply in the digestive tract. These friendly flora work hard to crowd out the types of bacteria and yeast you don’t want in your body. This is great— it’s why you’re taking probiotics in the first place! However, while healthy bacteria are taking hold and colonizing the digestive system, you might notice a few unexpected changes. You or your child may experience a little gas, along with changes in the frequency and texture of bowel movements (BMs). This is totally normal as your body adjusts, but we recommend upping your fluid intake during this phase.

Soon, your stomach will adapt and you’ll notice less gas. You might continue to see increased or decreased BMs as your body gets accustomed to its new gut health. A healthy gut means better absorption of nutrients, so your BMs are more efficient and better quality.

How will I know if it’s working?

Everyone’s a little different—some might feel changes within the first few weeks, and for others it could take up to two months. Some people might not even feel a change at all, but that doesn’t mean your probiotics aren’t doing their job. In the background, probiotics are balancing your gut, helping with nutrient absorption and boosting the immune system. If you’re eating a diet that’s rich in processed foods, your gut is likely in pretty bad shape. While probiotics are working their magic, you may notice a shift in BM’s or an increase in gas. Like we said, this will level out. However, if you have a relatively healthy gut, you may not notice a difference, especially in BMs— this doesn’t mean they aren’t working to keep you regular and boost your immune system.

Do CFUs matter?

CFUs reference an amount in microbiology that estimate the number of viable bacteria or fungal cells in a sample. Basically, a CFU is a unit of the good ‘bugs’ found in probiotics. CFU numbers on probiotic supplements can vary anywhere from several million to 50 billion. Researchers have concluded that an effective probiotic dosage for overall gut health is around 20 million CFUs per day. Probiotic variants with tens of billions of CFUs per serving are providing far more than necessary for general improved gut health. Most importantly, outrageous CFU counts may also imply that there’s a need to compensate for poor survival rates.

Can I take probiotics with my medication?

Whenever you add any supplement into your routine, you should make sure that you have received the all clear from your doctor to make sure you won’t have any unforeseen interactions.

Can I take two Jetson Probiotics formulas at once?

Yes, in fact, we encourage it. Our formulations are complimentary – meaning you’ll never get too much of one strain and too little of another. If you decide to do so, we suggest that you split up the doses: one in the morning, one in the evening.
