Biochem/physiol Actions

Nicotinuric acid (NUA) is a metabolite of niacin/vitamin B. Measurement of NUA levels in urine is used to indicate possible elevated nicotinamide adenine dinucleotide (NAD) catabolism. NUA may be used as a reference (standard curve) in the analysis of NAD and NUA catabolism. Nicotinic acid reduces triglycerides and increases high density lipoprotein(HDL) cholesterol.
