Red mould supplement pill linked to deaths and hospitalisations pulled from shelves in Japan

In Japan, Kobayashi Company has issued a recall of several health supplement brands containing the ingredient ‘benikoji’ following reports of kidney-related complaints from customers. The Japanese government ordered the recall after two deaths and more than 100 hospitalizations were suspected to be linked to the supplements.

The supplements in question contain red yeast rice, also known as “benikoji,” which is believed to be the cause of the health issues. Kobayashi Pharmaceutical, based in Osaka, is investigating the potential connection between their products and the adverse effects on kidneys. The ingredient Monascus purpureus, a red mould commonly used as a food colouring, is found in the recalled supplements.

In addition to Kobayashi’s products, over 40 other brands containing benikoji have also been recalled, including items like miso paste, crackers, and vinegar dressing. Health Minister Keizo Takemi has urged Kobayashi Pharmaceutical to provide information promptly, and the Ministry of Health, Labour, and Welfare is collecting data on potential health damage caused by the supplements.

Kobayashi Company is advising customers to discontinue the use of their products and to refrain from using them in the future. The official from the ministry warned that there may be more victims in the coming days and advised everyone to avoid benikoji, especially those with pre-existing health conditions.
