Fit Probiotic FAQs

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

Each of our products promote a healthy digestive environment and overall gut health.* Our prebiotic destabilizes the cell walls of undesirable bacteria in your gut and creates an environment where good bacteria (probiotics) can flourish.* Probiotics are live bacteria that provide health benefits to the body, commonly for restoring gut balance and support overall gut health.* Digestive enzymes speed up the breakdown of food for better nutrient absorption and digestive comfort.*

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 may adapt resulting in 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 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 the immune system.* If you’re eating a diet that’s rich in overly 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 if our formulation works for your gut.* 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 support your immune functions.*

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. If you decide to do so, we suggest that you split up the doses: one in the morning, one in the evening.

If you decide to take multiple Jetson formulas, make sure your total daily supplemental intake does not exceed the recommended daily allowance. Consult with your physician if needed.
