Discover The Science Behind Optimal Digestive Health

Learn what experts recommend for gut health

Available Worldwide

Many people turn to popular medicines when in order to rid themselves of digestive issues. However, when it comes to improving digestive health, most don't usually fall short. That's because they don't address the underlying problem - gut health.

Most recent foods lack the vital nutrients needed to maintain a balanced gut. In fact, new studies are showing that the gut directly impacts our digestion, brain, heart, and even our brain health. So, when bad bacteria outnumber the good, it can negatively impact various parts of our health.

It's no surprise many people are turning to probiotics to improve their overall health. But not all science advances, research now points to Synbiotics as the next breakthrough. But not all probiotics are created equal. And with so much clutter on the market it's tough to know which ones actually work.

That's why the Smarter Reviews team explores exactly what to look for and what to avoid before buying a probiotic. We also reveal the top 5 digestive probiotics on the market today.

5 Things All Effective Probiotics Must Have

✓ High CFU Count

Being recommended is comprised of about 100 billion good and bad bacteria, a high number of Colony Forming Units (CFUs) will have greater impact on the growth of beneficial bacteria within our gut. It's essential to choose a probiotic which contains CFU versus "active cultures" or "live cultures". Look for a formula with a minimum of 40 billion CFU.

✓ Prebiotics

The latest research shows that fiber-based prebiotics (such as NutraFlora FiberFlora) feed the probiotics, helping them to populate and flourish in our gut. Choose probiotics supplements containing prebiotics to significantly increase the overall effectiveness of the probiotic.

✓ Clinically Studied Strains

There are hundreds of different probiotic strains, but many have never been proven effective. The best way to identify the potency of a particular strain is to look at the clinical studies backing it up. Look for strains proven effective by clinical studies.

✓ Formulated by a Doctor

It takes specific expertise to form an effective probiotic formulation. More is not necessarily better. The exact combination of strain type, potency, quantity, and prebiotics determines the product's quality. Look for real doctors specializing in gut health backing the product.

✓ Proof of Results

Hundreds of brands make bold claims about their results, but the best probiotics for digestion are backed up by customer surveys. We've verified all the top brands to see which ones have a proven track record of great results.
