Nattokinase EPA・DHA
Sakanatto—Natto and Oily Fish’s Smooth-Flow Ingredients in One Capsule
Who This Is For and When to Use It
Product Overview
Kobayashi Pharmaceutical’s “Nattokinase EPA・DHA” is a supplement that condenses three ingredients into one capsule: “nattokinase,” a fermented component found in natto’s sticky texture, and “EPA” and “DHA,” which are abundant in oily fish. It is refined during manufacturing to reduce the natto odor and also contains the onion-derived quercetin glycoside “Sarasarared.” The soft capsule is easy to take once a day. This product is a food and is not intended to diagnose, treat, or prevent disease.

Each capsule contains nattokinase activity of 2,000 FU. It is formulated to provide an amount equivalent to approximately 1.5 packages (75 g) of commercially available natto (calculated based on one package of commercially available natto weighing 50 g).
