The development of IMARK, a Food for Specified Health Uses (FOSHU)
In 1998, Nissui began the development of a beverage which would allow people to easily get EPA within the constraints of their daily dietary lives. This resulted in the 2004 launch of IMARK, a supplement under the relatively new Food for Specified Health Uses (FOSHU, or tokuho in Japanese) classification. It was the first product of its kind in Japan to feature as active ingredients EPA and DHA (docosahexaenoic acid).
The product was dubbed IMARK in recognition and deference to the Inuit people, the study of whom led to the discovery of EPA. It is derived from the word imaq, which in the Inuit language means "sea".
IMARK is a product available exclusively through mail-order, but through word-of-mouth it has gradually gained considerable brand recognition, and regular delivery customers continue to increase. Due in part to the effectiveness of our Web ads, compared to April 2011, monthly delivery customers as of the end of September 2012 have risen by more than a factor of 2.6.
In response to the numerous requests received from IMARK customers, in October of 2012, we decided to use a more environmentally-friendly aluminum bottle for the product. Furthermore, we launched IMARK S, a FOSHU product that can be stored at room temperature.
