Our initial research on why other probiotics don’t work as well as they claim they would revealed a shocking fact: their probiotic strains don’t survive in the stomach! This is the point where we started building a probiotic that had the right formulation, and the strains were treated properly so that they can survive in your gut. After all, that’s what they’re supposed to do! SilverFern Ultimate Probiotic is your gut’s safety net.

It’s no surprise that this is our bestseller. If you suffer from stomach and digestive issues like gas, bloating, diarrhea, constipation, discomfort (like all of us), then the Ultimate Probiotic may just be the solution you have been looking for.

There’s a lot more we want to tell you. Things like:

  • How our Probiotic helps strengthen gut barriers
  • The science behind building up good bacteria and pushing out the bad stuff
  • The difficulties in correcting bacterial imbalances and permeability (aka leaking)
Ultimate Probiotics Advantages

There are 273 probiotic brands in the country. We’ve tried them all.

We've always been passionate about health and exercise. And yet, Phil (our co-founder) spent a majority of the winter for years (yes, years) with sinus infections and bronchitis. We knew we needed to find a healthy, preemptive solution to keeping him healthy and avoiding constant use of antibiotics. We tried everything under the sun—including the most recommended solution, probiotics.

Unfortunately, they weren’t working well. In most cases, someone who experiences no results moves on to the next solution. There’s a reason why we didn’t: we knew probiotics should work. It was surprising that leading brands weren’t showing results.

It’s only after we met Kiran Krishnan at a conference that the answer finally dawned on us. Kiran is an amazing microbiologist and clinical researcher specializing in digestive and gut health. He educated us on the importance of digestive health in relation to the immune system as well as so many other aspects of our health. Kiran then introduced us to his team's dietitian and director of scientific affairs, Aicacia Young. It’s this introduction, and the research that followed, that gave us the solution we were looking for

The problem was not with probiotics. The problem was that these probiotics were not treated properly so they could survive in the gut.

The science was right, but the business decisions other brands were making were not in our interest. That’s what led to Silver Fern, and ultimately, the Ultimate Probiotic.
