description Vitamin K2 Overview
Vitamin K2 is crucial because it directs calcium to the bones and teeth, preventing it from depositing in soft tissues like arteries (calcification). While not a direct antioxidant, by preventing vascular calcification, it supports cardiovascular health, which is a major aspect of long-term antioxidant defense. It is best taken alongside Vitamin D3 to ensure optimal mineral utilization and safety.
