Kosshin® Vitamin K2 (MK-7)

Not all Vitamin K2 ingredients are created equal. Kosshin® Vitamin K2 (MK-7) is produced in Japan through traditional fermentation of non-GMO Bacillus subtilis natto utilizing patented manufacturing technology protected by U.S. Patent 8,114,642 and Japan Patent 3,911,282. This carefully controlled process delivers a premium menaquinone-7 ingredient distinguished by exceptional purity, consistency, and quality.

While many Vitamin K2 ingredients can suffer from instability, variable quality, and the presence of cis isomers associated with synthetic production methods, Kosshin® delivers 100% natural, 100% trans MK-7 derived directly from natto fermentation. The result is a highly desirable Vitamin K2 ingredient that sets the gold standard for natural menaquinone-7 nutrition.

Backed by patented production technology and authentic Japanese natto fermentation, Kosshin® should be the go-to Vitamin K2 for formulators developing premium bone health, cardiovascular wellness, and healthy aging products.
