Overview of the Vitamin B3 (Nicotinamide)
The Vitamin B3 (Nicotinamide) blood test measures Nicotinamide, a form of Vitamin B3 involved in cellular energy metabolism.
The test contains 1 biomarker: Vitamin B3 (Nicotinamide).
Vitamin B3 is required to produce the coenzymes NAD and NADP, which participate in hundreds of metabolic reactions.
These pathways are essential for energy production, DNA repair, cellular signalling and redox balance.
Vitamin B3 can be obtained directly from food and can also be synthesised to a limited extent from the amino acid Tryptophan.
Severe deficiency causes pellagra, classically associated with dermatitis, diarrhoea and neurological or cognitive changes.
Pellagra is uncommon in the UK but may occur in severe malnutrition, alcohol dependence, significant malabsorption or rare metabolic conditions.
The test should be interpreted as a targeted nutritional investigation rather than as a general measurement of "cellular NAD".
What Does the Vitamin B3 (Nicotinamide) Test Check?
This test measures 1 biomarker.
Vitamin B3 (Nicotinamide)
Measures Nicotinamide status to support assessment of Vitamin B3 nutrition and metabolism.
Who May Benefit From the Vitamin B3 (Nicotinamide) Test?
Testing may be appropriate where dietary or clinical circumstances raise concern about Vitamin B3 deficiency.
People with severe dietary restriction or malnutrition - Reduced intake can lower Vitamin B3 availability.
People with chronic alcohol misuse - Poor nutrition can increase deficiency risk.
People with significant gastrointestinal malabsorption - Nutrient absorption may be impaired.
People with unexplained dermatitis and broader nutritional concerns - Pellagra produces characteristic skin findings.
People with chronic diarrhoea and nutritional risk - Vitamin B3 deficiency may coexist with other micronutrient deficiencies.
People undergoing specialist nutritional assessment - B3 measurement can complement other B vitamins.
People with a previous low Vitamin B3 result - Repeat testing may assess response to treatment.
How to Prepare
Do not use high-dose Niacin or Nicotinamide supplements without considering the potential for adverse effects.
Discuss substantial supplementation with an appropriate healthcare professional.
Symptoms and Reasons to Consider the Vitamin B3 (Nicotinamide) Test
Severe Vitamin B3 deficiency is traditionally associated with the features of pellagra.
Photosensitive dermatitis - Pellagra can produce characteristic inflammation on sun-exposed skin.
Persistent diarrhoea with malnutrition - Gastrointestinal involvement can occur in severe deficiency.
Sore or inflamed mouth and tongue - Mucosal changes may develop.
Confusion or cognitive change in severe deficiency - Neurological involvement can occur in advanced pellagra.
Marked weakness with poor nutritional intake - Multiple deficiencies may coexist.
Severe restrictive diet - Biochemical deficiency can occur before classic symptoms become obvious.
These symptoms are not specific to Vitamin B3 deficiency.
Neurological change, severe diarrhoea or significant malnutrition requires broader medical assessment.

When Will I Receive My Results?
The current expected turnaround is approximately 8 days after laboratory receipt.
Vitamin B3 is a specialist nutritional assay requiring dedicated analysis.
The result is released once analytical quality control and laboratory authorisation are complete.
Specialist referral or a sample-quality issue may occasionally extend reporting.
Understanding Your Results
A low result can support Vitamin B3 deficiency in the appropriate nutritional and clinical context.
Because clinically significant B3 deficiency usually occurs alongside broader nutritional problems, additional vitamin and mineral assessment may be appropriate.
A result within the laboratory reference interval suggests adequate measured Nicotinamide status.
Higher concentrations are commonly associated with supplementation.
This test measures Vitamin B3 status and does not directly quantify intracellular NAD+ reserves or biological ageing.
