NOW combines two essential nutrients, vitamin D₃ (1,000 IU) and vitamin K₂ (45 mcg), both extensively researched for their vital roles in supporting bone, dental, and cardiovascular health. Vitamin D₃ promotes calcium absorption and transport, contributes to proper insulin action and glucose metabolism, and plays an important role in immune system function. Vitamin K₂ supports the formation of a strong bone matrix and proper calcium utilization in vascular structures, helping maintain arterial health. Together, these nutrients work synergistically to promote strong bones and teeth while supporting cardiovascular and overall wellness.
