Arsenic Toxicity Associated with Dietary Mineral Supplements — California, 2017
- Researchers found that a patient with severe arsenic poisoning was likely exposed by consuming multiple dietary supplements. Two of the patient’s dietary mineral supplements contained arsenic at levels that may increase the risk of both cancer and other health effects.
- Dietary mineral supplements are commonly used and often derived from natural sources that might contain arsenic. Clinicians, therefore, should be aware of the potential for arsenic toxicity in patients taking dietary mineral supplements, particularly when multiple supplements are taken together.
- Companies might consider testing raw materials and/or products derived from natural sources and appropriately labeling any contaminants.
- The California Department of Public Health is obtaining additional information to allow us to develop clear advice for consumers.
“We found that some natural mineral supplements contain arsenic at levels that could be harmful to health, but there is no requirement to label for naturally occurring contaminants like arsenic.”
