While Vitamin B3 is especially effective, other vitamins also encourage circulation:

Vitamin E is an antioxidant that helps prevent blood clots and encourages red blood cell production. It boosts smooth blood flow and may ease leg cramps caused by poor circulation.
Vitamin C boosts collagen production, which enhances blood vessel walls. It also decreases inflammation, helping to keep arteries flexible and open.
Vitamin D may help prevent arterial stiffness and regulate blood pressure, which indirectly boosts circulation in the legs and feet.
Vitamin B12 helps create red blood cells. A deficiency can cause anemia, which reduces oxygen flow to tissues and contributes to poor circulation.
Best Sources and Supplementation

Vitamin B3 is found in foods like chicken, turkey, tuna, salmon, brown rice, and legumes. For those with circulation issues, supplements may offer higher doses as recommended by a healthcare professional. However, niacin supplements should be taken cautiously, as high doses can lead to side effects such as flushing, dizziness, or liver damage if misused.

Final Thoughts
If you’re dealing with cold feet, numbness, or fatigue in your legs, boosting your circulation should be a priority. While Vitamin B3 is one of the best options to encourage blood flow, combining it with a healthy diet, regular exercise, proper hydration, and medical advice provides the best long-term results. Always visit a doctor before starting any new supplement regimen, especially if you have underlying health conditions.
