NOW Foods Vitamin K2 100 mcg MK-4 100 Capsules

Menaquinone-4 is the form of K2 used here. Vitamin K participates in normal blood clotting and calcium-related processes, while the alfalfa powder is a separate 250 mg ingredient within each capsule.

This product should be distinguished from NOW's MK-7 formula even though both declare 100 mcg K2. NOW recommends one capsule daily with a meal. The label identifies blood-thinning medicines and aspirin in its precautions and directs stopping two weeks before surgery or if stomach upset occurs. It also excludes pregnancy, nursing and aspirin allergy or contraindication.
