Jarrow Formulas MK-7 delivers 90mcg of Vitamin K2 in the menaquinone-7 form, presented as easy-to-swallow softgels. Each pack contains 90 softgels, with one softgel constituting the recommended daily serving. The MK-7 used in this formula is produced through natural fermentation involving Bacillus subtilis subsp. natto, the same bacterial strain associated with the traditional Japanese food nattō.
Vitamin K2 as MK-7 (Menaquinone-7) is a fat-soluble nutrient that occurs naturally in certain fermented foods. This particular form is noted for remaining active in the body for longer than K1 or the shorter-chain MK-4 variant. Jarrow Formulas is a well-regarded US supplement brand with a long-standing commitment to quality manufacturing standards.
This product is well suited to those following a diet low in fermented foods, older adults looking to maintain their micronutrient intake, and anyone seeking a straightforward Vitamin K2 supplement from a trusted brand.
