Abstract: Some strains of Bacillus coagulans can survive extremes of heat, stomach acid and bile acids, to which commonly consumed probiotics are susceptible. A toxicological safety assessment was published in 2009 on a proprietary preparation of B. coagulans – GanedenBC30™ – a novel probiotic. It was concluded that GanedenBC30™ is safe for chronic human consumption based upon scientific procedures, supported by a safe history of use (). A one-year chronic oral toxicity study combined with a one-generation reproduction study was conducted to further investigate safety of long-term consumption. The one-year study of GanedenBC30™ administered to male and female HsdBrlHan: Wistar rats in their diet showed no signs of toxicity at the highest dose tested. The conclusion from the reproduction toxicity study is that administration of GanedenBC30™ in the diet caused no signs of toxicity in the parental generation (male or female) nor the F1 offspring. Using the lowest NOEL of 1948mg/kg concluded at the end of the 1-year feeding study, a 100-fold safety factor, a test article concentration of 6.88×1010 CFU (colony forming units) per gram, and an average 70kg human, it is determined that GanedenBC30™ is safe for chronic consumption at up to 9.38×1010 CFUs per day.
