Vitamin B3 (Niacin) Unit Converter
Vitamin B3 (Niacin, Nicotinic Acid) is a water-soluble vitamin that is converted in the body to the coenzymes NAD and NADP, which are essential for energy metabolism.
Deficiency can lead to Pellagra, while high doses are sometimes used to manage cholesterol. This converter facilitates switching between the standard mass units (ng/mL, μg/L) and the international SI molar units (nmol/L).
Mass Units
StandardNanograms per milliliter (Numerically equivalent to μg/L).
SI Units / Molar
Nanomoles per liter (International Standard).
Clinical Context
Reference Ranges (Plasma/Serum):
• Normal: 0.5 – 8.45 μg/mL (Usually measured as specific metabolites like N-methylnicotinamide in urine or plasma).
Note: Testing methods vary. Always consult local lab ranges.
Clinical Significance:
• Deficiency (Pellagra): Characterized by the “4 Ds”: Dermatitis, Diarrhea, Dementia, and Death.
• Toxicity: High doses can cause flushing (“Niacin flush”), pruritus, and liver damage.
Conversion Logic:
Molecular Weight of Nicotinic Acid: ~123.11 g/mol.
1 ng/mL ≈ 8.12 nmol/L.
1 nmol/L ≈ 0.123 ng/mL.
