Vitamin B3 (Niacin)
Vitamin B3, also called niacin, has a unique effect at higher prescription doses: it can cause vasodilation, meaning temporary widening of blood vessels. This can lead to the familiar “niacin flush” — warmth, redness, or tingling of the skin.
Potential roles of niacin include:
- Supporting healthy blood vessel function
- Helping maintain normal cholesterol levels at certain doses
- Supporting energy metabolism

- Flushing and itching
- Liver problems
- Increased blood sugar
- Gout flare-ups in susceptible people

Vitamin D

Vitamin E
Acts as an antioxidant, but high-dose supplements are not recommended for everyone and may have
