The vitamin you’re referring to is likely Vitamin B3 (Niacin). Here’s a detailed explanation:
Vitamin B3 (Niacin) – The Circulation Booster
How It Works
- Niacin helps dilate blood vessels, which improves blood flow throughout the body.
- This effect can reduce blood pressure slightly and improve oxygen delivery to tissues.
- It also helps lower LDL (“bad”) cholesterol and raise HDL (“good”) cholesterol, supporting cardiovascular health.
Sources of Niacin
- Animal-based:
- Chicken, turkey, tuna, salmon, beef
- Plant-based:
- Peanuts, sunflower seeds, brown rice, mushrooms, fortified cereals
Recommended Daily Amount
- Adults typically need 14–16 mg/day.
- Supplements are available, but high doses can cause flushing, itching, or liver issues, so only take under medical supervision.
Other Nutrients That Help Circulation
- Vitamin C – supports blood vessel health and elasticity
- Vitamin E – prevents blood clots and supports smooth blood flow
- Omega-3 fatty acids – reduce inflammation and improve circulation
✅ Bottom line: Niacin (Vitamin B3) is the vitamin most known for opening blood vessels and improving circulation, but balance is key — always get most vitamins from food rather than mega-doses of supplements.
If you want, I can make a short list of 5 foods rich in niacin that naturally boost circulation — all easy to include in daily meals.
Do you want me to do that?
