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 - GanedenBC(30)™ - a novel probiotic. It was concluded that GanedenBC(30)™ is safe for chronic human consumption based upon scientific procedures, supported by a safe history of use (Endres et al., 2009). 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 GanedenBC(30)™ 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 GanedenBC(30)™ in the diet caused no signs of toxicity in the parental generation (male or female) nor the F1 offspring. Using the lowest NOEL of 1948 mg/kg concluded at the end of the 1-year feeding study, a 100-fold safety factor, a test article concentration of 6.88×10(10) CFU (colony forming units) per gram, and an average 70 kg human, it is determined that GanedenBC(30)™ is safe for chronic consumption at up to 9.38×10(10) CFUs per day.
