Bio-Kult is a supplement company that provides multispecies, multi strain probiotic products. All of Bio-Kult’s supplements are manufactured in a U.K.-based facility that adheres to the current good manufacturing practices (CGMPs). Products also undergo in-house testing to guarantee stability and bacterial count for up to 2 years. Unlike many other probiotics on the market, Bio-Kult’s capsules don’t have to be refrigerated because they have a special protective coating created during processing.
