The so-called first medicine is registered by foreigners in Japan, specifically for tour groups. Few Japanese locals know it and will not buy it.

Regardless of quality, even if the price is much more expensive than that of Japanese brands,

The enzymes of First Pharmaceutical are n times more expensive than Japanese brands. (For example, the dosage of enzymes such as Kobayashi Pharmaceutical and DHC does not exceed 2,000 yen a month)

The effect of health care products is just like that, mainly psychological, so there is no need to buy so expensive.
