The Role of Probiotics in the Amelioration of Cadmium Toxicity

Cadmium is extremely toxic heavy metal, and there is no specific, safe, and efficacious therapeutic management of cadmium toxicity. Scientific literature reveals several probiotic microorganisms which alleviate experimentally induced cadmium toxicity in animals. The present review attempts to collate the experimental studies on probiotics and probiotic-derived natural products with cadmium toxicity ameliorative effects. Literature survey revealed that seven (7) types of probiotic microorganisms exhibited significant protection from cadmium toxicity in experimental pre-clinical studies. Clinical study with significant outcome was not found in literature. From the outcomes of the pre-clinical studies, it appears that probiotics have the prospect for alleviation and treatment of cadmium toxicity.
