Taiwanese media say a local woman suffered kidney failure after taking a supplement containing a "beni-koji" malted rice ingredient made by Japanese drugmaker Kobayashi Pharmaceutical.

News outlets reported on Thursday that the woman who is in her 70s lives in the southern city of Kaohsiung.

They said she was diagnosed with acute kidney failure in March last year and had started to take the supplement three or four years ago. They added that a Taiwanese company manufactured the supplement using the beni-koji ingredient.

The reports cited accounts shared by the patient's husband.

More than 30 businesses in Taiwan are recalling products containing the ingredient or taking other measures.
