The compound known as vitamin B3 or niacin, used therapeutically to treat pellagra and high cholesterol, and in food fortification.
Linguistics
Semantic Notes
While 'nicotinic acid' is the precise chemical name, the term 'niacin' is more common in nutritional contexts. 'Nicotinic acid' can refer specifically to the form used for cholesterol management, distinct from nicotinamide, another form of B3.
Dialectal Variation
British vs American Usage
Differences
No significant difference in the scientific term itself. 'Niacin' is equally common in both varieties. The compound name follows standard international nomenclature.
Connotations
Identical connotations in both dialects: strictly scientific/medical/nutritional. The 'nicotinic' component may wrongly suggest a link to nicotine for laypeople, but this is a linguistic, not dialectal, association.
Frequency
Equally low-frequency in general language. Use is confined to scientific, medical, and nutritional texts/contexts in both the UK and US.

Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate 'nicotinic' as 'никотиновый' in isolation, as this strongly implies 'related to nicotine/tobacco'. The standard Russian term is 'никотиновая кислота', but the association with nicotine is a common false friend. 'Ниацин' is a safer, more modern term.
Common Mistakes
- Mispronouncing it as 'nik-oh-TINE-ik' (stress on 'tine'); correct is 'nik-oh-TIN-ik'.
- Confusing it with 'nicotinamide' (a related amide form).
- Assuming a direct health link to nicotine/tobacco.
- Using 'nicotinic acid' in casual conversation instead of 'niacin'.

Frequently Asked Questions
No, they are completely different compounds. Nicotine is an addictive stimulant from tobacco. Nicotinic acid (niacin) is an essential vitamin, named because it was first derived from nicotine oxidation in 19th-century research.
Primarily to raise HDL ('good') cholesterol and lower triglycerides and LDL cholesterol. It is also used to treat severe niacin deficiency (pellagra).
A harmless but often uncomfortable 'niacin flush' – redness, warmth, and itching of the skin, usually on the face and chest – caused by blood vessel dilation.
In everyday or nutritional contexts, use 'niacin' or 'vitamin B3'. 'Nicotinic acid' is preferred in precise chemical, pharmaceutical, and clinical contexts to distinguish it from other forms like nicotinamide.
