Vitamin B3 Blood Test
The Vitamin B3 Blood Test measures Nicotinic Acid and Nicotinamide levels in the blood.
This test measures Nicotinic Acid and Nicotinamide levels in the blood. Nicotinic Acid (known as Niacin) is a form of Vitamin B3, part of the B complex, that primary function is to assist the digestive system, skin, and nerves by converting food to energy. Nicotinamide is the metabolite formed when Niacin breaks down in the intestines. You can find Niacin in certain foods such as leafy greens, milk, eggs, fish, lean meats, legumes, peanuts, and poultry.
Although found naturally in plants and animals, Niacin is also offered as a dietary supplement. The Niacin supplement functions by lowering cholesterol and triglycerides in the blood. As a result, Niacin helps reduce the risk of a heart attack in people with a high-risk factor or who have already had a heart attack. The Niacin supplement also helps people that may have a Vitamin B3 deficiency.
A deficiency of Vitamin B3 causes pellagra. The symptoms include:
- Digestive problems

- Increased blood sugar (glucose) level
- Liver damage
- Peptic ulcers
- Skin rashes
