Vitamin B3, also known as niacin, is essential for healthy blood circulation. It helps widen blood vessels (vasodilation), allowing oxygen-rich blood to flow more easily to the heart, brain, muscles, and extremities.
This improved circulation may support higher energy levels, better oxygen delivery, and warmer hands and feet in people with poor blood flow. Some people also experience a harmless “niacin flush,” a warm sensation linked to increased circulation.
Niacin may also support heart health by helping maintain healthy cholesterol levels and promoting artery function.
You can find vitamin B3 in foods like salmon, chicken, turkey, peanuts, mushrooms, and fortified grains, or take it as a supplement when needed.
Good circulation is key to overall health—and vitamin B3 plays a powerful role in keeping it strong.
