Blood circulation supplements help keep blood vessels open and responsive so oxygen and nutrients can move freely throughout the body. For example, omega-3 fatty acids help reduce blood fats, while B vitamins break down homocysteine, which can affect vessel health when elevated. Additionally, CoQ10 supports energy production in the heart and vessels, and antioxidants protect tissues from oxidative stress. Together, these functions help improve blood flow efficiency, support extremity warmth, and maintain healthy heart performance during daily activities.
