Order Vitamin B3 Niacin Testing | Deficiency TestVitamin B3, also called niacin, is a water-soluble nutrient that the body uses in energy metabolism and in the maintenance of normal skin, nerves, and digestive function.

About Vitamin B3 Niacin Testing | Deficiency Test in Grand Rapids
Niacin testing is typically ordered when a clinician suspects a nutritional shortfall or when symptoms suggest that B3 status should be evaluated.
Like other B vitamins, niacin participates in converting carbohydrates into glucose and supports the reactions that release energy from food. The body can also produce niacin from the amino acid tryptophan, though dietary sources such as meat, fish, poultry, fortified grains, and legumes remain the primary contributors to overall status.
Deficiency in niacin can develop gradually. Early signs may include fatigue, changes in appetite, and digestive discomfort, while more prolonged shortfalls can affect the skin and nervous system. Because these symptoms overlap with those of other nutrient deficiencies, a blood measurement helps distinguish niacin status from other possible causes.
Results are interpreted alongside a person's diet, medical history, and other laboratory findings. A low value does not by itself establish a diagnosis, and a value within the reference range does not guarantee adequate tissue stores in every clinical situation. Treatment decisions, including supplementation, are made by a qualified healthcare professional.
