About Vitamin B3 Niacin Testing | Deficiency Test in Port Huron
Vitamin B3 is essential for converting carbohydrates into glucose and supporting cellular energy production.
Niacin exists in two primary forms—nicotinic acid and nicotinamide—and is obtained from foods such as meat, fish, whole grains, and legumes. The body can also synthesize niacin from the amino acid tryptophan.
A deficiency in niacin can lead to symptoms that include fatigue, digestive issues, and skin changes. Severe and prolonged deficiency may result in pellagra, a condition characterized by dermatitis, diarrhea, and neurological disturbances.
This test is typically ordered when a healthcare provider suspects inadequate niacin intake, absorption problems, or increased nutritional needs. Results are interpreted alongside clinical findings and other laboratory values.
