⭐ Niacin (Vitamin B3)
Why it works
-
Niacin can cause vasodilation, meaning it widens blood vessels.
-
This increases blood flow to the skin and peripheral tissues.
-
The effect is often felt as the classic “niacin flush” — a warm, red tingling sensation caused by blood-vessel expansion.
Potential Benefits
-
Improved peripheral circulation
-
Better lipid (cholesterol) profile in some cases
-
Supports energy metabolism
⚠️ Important Notes
-
High-dose niacin supplements can cause flushing, itching, stomach upset, and—at prescription-level doses—may affect the liver.
-
Extended-release forms reduce flushing but should only be used under medical supervision.
-
People with liver disease, ulcers, gout, or diabetes should be cautious.
If you want, I can help you with:
✅ safe dosage ranges
✅ foods high in niacin
✅ other nutrients that support circulation (e.g., vitamin E, omega-3s, L-arginine)
