Why D3 and K2 Are Important
Both vitamin D3 (cholecalciferol) and K2 (menaquinone) play significant roles in calcium metabolism and bone health. While vitamin D3 boosts calcium absorption in the gut, vitamin K2 directs calcium to the bones and teeth rather than the blood vessels and soft tissues, reducing the risk of cardiovascular issues. Understanding their benefits and how they work together can help you select the best D3 K2 supplement for your health needs.
