Images of Kobayashi Pharmaceutical's offices in Tokyo and Osaka, as dietary supplements at the centre of an expanding health scare have now been linked to at least 157 hospitalisations, a health ministry official said Tuesday. The figure reflects an increase from the 114 hospitalisation cases that Kobayashi Pharmaceutical said on Friday were linked to its products containing red yeast rice, or "beni koji". The company said it was investigating five deaths potentially linked to the dietary supplements, which are meant to lower cholesterol. IMAGES
