NOW Foods Vitamin K-2 (MK-4) 100 mcg is a high-quality dietary supplement designed to support bone strength, calcium metabolism, and overall structural health. While Vitamin K has long been associated with normal blood clotting, modern nutritional science recognizes Vitamin K-2 as an essential nutrient for bone, cardiovascular, and nervous system function.
This formula contains Menaquinone-4 (MK-4), a biologically active and well-researched form of Vitamin K-2 that plays a crucial role in directing calcium to where it is most beneficial—such as bones and teeth—while helping prevent unwanted calcium accumulation in soft tissues.
Vitamin K-2 supports the activation of proteins involved in forming a strong bone matrix, making it particularly valuable for individuals focused on long-term skeletal health. In addition, its role in calcium regulation contributes to maintaining healthy arterial structure, supporting overall cardiovascular wellness.
Each capsule also includes alfalfa powder, a natural source of phytonutrients traditionally valued for its mineral-supportive properties. The supplement is vegetarian/vegan friendly, Halal certified, Non-GMO, and manufactured under strict GMP quality standards.
Backed by NOW Foods’ decades-long commitment to quality and purity, this Vitamin K-2 supplement is a smart addition to a balanced wellness routine—especially for adults mindful of bone and heart health.
Suggested Use
Take 1 capsule daily with a meal, or as directed by a healthcare professional.
