An 89-year-old man in the U.K. who passed away last year died from complications of vitamin D overdose, an investigation has revealed. This case has sparked concerns regarding the potential consequences of consuming excessive supplements, with experts calling for a revision of supplement packaging rules in the country.

David Mitchner from Surrey, southeast England, died in May 2023 due to vitamin D toxicity, hypercalcemia, and cardiac and kidney failure, as per reports. Mitchner had been consuming vitamin supplements for a minimum of nine months leading up to his demise, and a pre-death test revealed vitamin levels at very high levels of 380.
