This issue often stems from underlying health conditions such as peripheral artery disease (PAD), diabetes, or prolonged inactivity. While medical treatment and lifestyle adjustments are key, specific vitamins—especially Vitamin B3—can significantly support vascular health and circulation.

Niacin, or Vitamin B3, plays a central role in promoting circulation. It helps widen blood vessels, improving blood flow to areas like the legs and feet. Niacin also works to reduce LDL (bad cholesterol) while increasing HDL (good cholesterol), which supports healthier arteries.

By improving endothelial cell function—the cells lining blood vessels—niacin helps regulate blood pressure and vessel flexibility. This is especially helpful for those dealing with narrowed or hardened arteries.

When taken in supplement form, some people experience a “niacin flush”—a temporary sensation of warmth or tingling—as circulation improves, particularly in the limbs.
