About Vitamin K2

Vitamin K2 declaration on Supplement Facts depends on the amount per serving and applicable conditions in 21 CFR 101.36(b)(2). Confirmed absent or amounts below the applicable declaration threshold must be omitted; missing information is unknown, not zero. The adult/children 4+ reference is 120 mcg. Select the intended population before calculating %DV. For minerals, use the confirmed elemental amount rather than the whole salt weight. Nutrition Facts follows separate food-label declaration rules.
