Otsuka Pharmaceutical

Otsuka Pharmaceutical leverages the know-how it has cultivated in pharmaceutical business to develop products that support people's health in their daily lives. The company aims to do so through the creation of new value without regard to current trends or popular taste, developing innovative products that gain favor around the world.
One example is the 2014 launch of the equol-containing food EQUELLE to promote women's health and beauty.
A second example resulted from the research by Otsuka Pharmaceutical’s nutraceutical research centers in Otsu and Saga Japan on the interconnectedness between the digestive tract, nutrition and exercise. These efforts culminated in the 2017 launch of BODYMAINTÉ.
Earlier pathbreaking examples include the electrolyte drink POCARI SWEAT, based on the concept of a "drinkable IV", the balanced nutritional food Calorie Mate which makes it easy to access the five essential nutrients, and the soy bar SOYJOY which provides the nutritional goodness of soy.
The development of these products has been carried out both at Otsuka's own research institutes, as well as at external institutes with which we collaborate to uncover additional scientific evidence and maximize the health-improving value of our products.
