What is Vitamin B3 Niacin?
Vitamin B3, also known as niacin, is an essential nutrient that the body uses to convert energy from food, keep the skin and nerves healthy, and regulate cholesterol levels.
Why should you have Vitamin B3 Niacin tested?
A test for vitamin B3 is useful for checking whether you have a deficiency or an excess, both of which can impact your health. People with a restricted diet, chronic health conditions, or certain genetic disorders may be at higher risk for a vitamin B3 deficiency or excess.
What does it indicate?
The vitamin B3 test indicates the amount of niacin in the blood. This can help in diagnosing nutritional deficiencies or in monitoring the health of people using supplements or medications that affect niacin levels.
What does a high Vitamin B3 level mean?
A high level of vitamin B3 can indicate excessive intake, either through diet or supplements, and may lead to niacin toxicity. Symptoms of toxicity include skin rash, itching, nausea, and liver damage.
What does a low Vitamin B3 level mean?
A low level of vitamin B3 can indicate a deficiency, which may lead to pellagra, a condition characterized by dermatitis, diarrhea, dementia, and in severe cases, death.
