Molybdenum Toxicity: Risks and Safety in Humans

There are no known toxic effects of molybdenum in humans, even at very high exposures. While there are some animal studies demonstrating toxicity, animal experiments have not been found to predict molybdenum toxicity in humans. Molybdenum is also not genotoxic, carcinogenic or teratogenic. This means that it does not cause mutations, cell tumors, or birth defects.
