A newly created multivitamin possesses many protective health functions. To investigate its safety when applied in medical treatment and when used as a food supplement, we studied its acute oral toxicity and 13-week oral toxicity in mice. The results showed that the oral lethal dose, 50% (LD 50) of the biomass of the multivitamin in mice was greater than 2492mg/kg body weight (BW) and that poisoned mice recovered within 72h. The no observed effect level (NOEL) of long-term consumption was more than 249.3mg/kg BW for haematological parameters, c...
