17 Targeted Probiotic Strains (including Lactobacillus， Bifidobacterium and Streptococcus) to efficiently counter indiscriminate broad-spectrum antibiotics and other lifestyle choices that potentially deplete the gut microbiome.

6 Billion Colony Forming Units (CFU) per BIO-tract® pearl. Power-17 uses patented time-release technologies to bypass stomach acids and deliver the most number of probiotic strains and highest levels of live bacteria to your intestines.

Easy to Swallow. This tiny pearl is much smaller (and therefore much easier to swallow!) than standard capsules.

Longer Shelf Life & No Refrigeration Necessary. The patented LiveBac® manufacturing process allows us to offer a guaranteed shelf life of 18 months from the date of manufacture. Many other probiotics expire quickly after they are manufactured because the process they use actually kills the live bacteria that needs to reach your gut.

Once per Day. With time-release delivery， the full benefits are delivered deep inside your GI tract throughout the day.
