As we get older, taking care of our cardiovascular health becomes increasingly important. Healthy blood vessels, regular physical activity, a balanced diet, and good control of blood pressure and cholesterol all play important roles in maintaining circulation.
One vitamin that often gets attention in discussions about blood vessels is niacin, also known as vitamin B3.
But there is an important detail that many social-media posts leave out: while niacin can affect blood vessels, it should not be viewed as a miracle treatment for poor circulation.
So what exactly does niacin do?
What Is Niacin?
Niacin is one of the B vitamins your body needs to function properly.
Its main role is helping the body convert carbohydrates, fats, and proteins from food into usable energy. It also supports normal function of the skin, nervous system, and digestive system.
Most people can obtain enough niacin through a normal diet.
Foods that contain vitamin B3 include:
- Chicken and turkey
- Fish
- Beef
- Peanuts
- Mushrooms
- Whole grains
- Fortified cereals
- Some legumes
A deficiency is uncommon in people who eat a varied diet.
