UT CALM by Silver Fern™ Brand goes beyond tackling the symptoms of UTIs. UT CALM attacks the root cause of UTIs by helping to crowd out pathogenic bacteria, restore microbial balance, and reduce adhesion of unwanted microbes, all while soothing irritation.!

Help to restore your Microbial Balance*

A Natural Approach to UTIs

Recurring UTIs are an uncomfortable problem for many women and to make matters worse, antibiotic-resistant urinary tract infections are also on the rise.1 Antibiotics treatments are becoming less and less effective and can have negative effects on the gut biome. We knew there had to be a better way. The Silver Fern™ team formulated an incredible natural solution for dealing with the symptoms and causes of UTIs by combining spore-forming Bacillus probiotics (precision probiotics), cornsilk extract, D-mannose, and cranberry extract. Look no further than UT Calm by Silver Fern™ for unparalleled natural UTI relief!

What Causes UTIs?

  • Escherichia coli (65% to 90% of UTIs are from E. coli)5,16
  • Klebsiella bacteria5
  • Proteus bacteria5
  • Pseudomonas aeruginosa5
  • Enterococcus bacteria5
  • Candida albicans6
Silver Fern™ Brand’s UT CALM attacks the root cause of UTIs

Why Don’t UTIs go Away?

  • A growing number of UTIs can no longer be treated with most common antibiotics.2
  • An Overabundance of uropathogenic bacteria.3

The Solution

UT CALM by Silver Fern™ Brand combines a precision probiotic with Cranberrex™ Cranberry Extract, D-Mannose, and Corn Silk (Stigma maydis) for an effective and natural approach for dealing with the symptoms of UTIs.
