What’s preventing you from living your best life?

Healing Your Gut
Your gut is made up of trillions of bacteria that affect your overall health. An overwhelming presence of bad bacteria can lead to numerous health issues from a slow metabolism all the away to more serious issues like Crohn’s disease and Candida yeast overgrowth. Ultimate Probiotic can help you to overcome these issues by providing balance to your gut which help solve many of these health issues.

Clinical Doses of Effective Probiotic Strains
Ultimate Probiotic contains the clinical doses of the multifunctional probiotic strains you need. The Bacillus and Saccharomyces Boulardii probiotic strains in our probiotic are some of the most clinically researched and proven probiotics for improving gut health. Most probiotics are filled with Billions and Billions of CFU’s of ineffective probiotic strains. Avoid the useless filler probiotics and make sure you’re giving your body the right strains it needs with the Ultimate Probiotic.

Survivability
Silver Fern™ Brand’s unique spore form probiotics are 100% guaranteed to survive through the acidic environment of your stomach. You can rest assured that all 8 billion CFU’s will survive through your gut and go to work. Most other probiotics aren’t spore form and die well before they reach your gut, rending their billions of CFU’s completely useless. A dead probiotic isn’t a probiotic at all!

DNA Verified
Our probiotic strains are lab tested and verified by third-party lab Sun Genomics. This ensures that you are getting the right strains to restore your gut health and free you from all your stomach issues. A recent study done by U.C. Davis found that only 1 in 16 probiotics available online contained what they claimed on the label. Have the confidence that you’re getting what you pay for when you pick up your own Ultimate Probiotic.

Guaranteed Results
Restoring your gut health is not an overnight fix. Many of our customers see an immediate improvement within days of consistently taking the Ultimate Probiotic, but most feel real improvement happens within 90 days. If for any reason you are unsatisfied we offer a 100% guarantee on our probiotics. Just look at what our customers are saying, we know you’ll love your improved health!
