Vitamin B3 (Niacin) Test
This blood test is used to determine Vitamin B3 (Niacin) deficiencies. Niacin (vitamin B3, also known as nicotinic acid) plays a role in converting carbohydrates into glucose, metabolizing fats and proteins, and keeping the nervous system working properly. Niacin also helps the body make sex-related and stress-related hormones and improves circulation and cholesterol levels.
