Unlike nicotinic acid (the flushing form), nicotinamide does not cause skin redness, tingling, warmth or itching. It does not bind to the prostaglandin receptors responsible for the niacin flush. The vast majority of users experience no flush whatsoever at 500mg nicotinamide.
Nicotinamide niacinamide UK — exactly the same compound — two names for the identical chemical. Both are the flush-free vitamin B3 nicotinamide UK amide form, and both share all 6 authorised EU/UK health claims for niacin.

Nicotinamide (also called niacinamide) is the amide form of niacin — a distinct chemical from nicotinic acid, the flushing form. The critical difference: nicotinamide does not activate the GPR109A prostaglandin receptors responsible for the niacin flush, making it the preferred choice for anyone who wants the full nutritional benefits of vitamin B3 without skin redness, tingling or warmth. Nicotinamide converts efficiently into NAD via the salvage pathway and shares all six authorised EU/UK health claims for niacin. It is the most widely recommended form of B3 for general supplementation by healthcare professionals and dermatologists.

🔬 Nicotinamide (Niacinamide) — The Science
Educational context only — health claims for this product are limited to the 6 authorised claims above.
⚗️ What Is Nicotinamide?
Nicotinamide (pyridine-3-carboxamide) is the amide form of vitamin B3 — one step along from nicotinic acid in the niacin metabolic pathway. It is water-soluble and found naturally in meat, fish, eggs, dairy and green vegetables. Unlike nicotinic acid, nicotinamide does not carry a carboxylic acid group, which is why it does not interact with prostaglandin receptors and does not cause the niacin flush. The body converts nicotinamide efficiently into NAD and NADP via the salvage and Preiss-Handler pathways.
🔬 Nicotinamide → NAD — The Salvage Pathway
Nicotinamide is a nicotinamide NAD precursor UK — it is converted into NAD (nicotinamide adenine dinucleotide) in cells via the salvage pathway — a highly efficient enzymatic route that converts nicotinamide → nicotinamide mononucleotide (NMN) → NAD. NAD is the coenzyme required in over 400 enzymatic reactions across all body tissues, including energy production in the mitochondria, DNA repair, and sirtuin activation. The salvage pathway is considered more efficient than the Preiss-Handler pathway used by nicotinic acid. All NAD content here is educational context — not a health claim.
✅ Why No Flush — The Mechanism
The niacin flush is caused specifically by nicotinic acid binding to GPR109A (nicotinic acid receptor) on skin immune cells (Langerhans cells), triggering prostaglandin D2 and E2 release and subsequent capillary vasodilation. Nicotinamide does not bind GPR109A. This is a structural consequence of the amide group replacing the carboxylic acid — the molecule is chemically too different to activate the same receptor. Even at high doses, nicotinamide does not produce the flush in the vast majority of users.
💊 Nicotinamide, NMN and NR — What's the Difference?
Nicotinamide, NMN (nicotinamide mononucleotide) and NR (nicotinamide riboside) are three different compounds related to vitamin B3 and the NAD synthesis pathway. Nicotinamide is the basic amide form of niacin. NR is nicotinamide combined with a ribose sugar — a nucleoside form that enters the NAD pathway at the NMN stage. NMN is a mononucleotide — one step further along, the direct immediate precursor to NAD. NMN and NR are typically used at much lower doses (250–500mg) than nicotinamide because they enter the NAD pathway at a later stage. Educational context only.

❓ Frequently Asked Questions — B3 Nicotinamide 500mg Capsules UK
What is nicotinamide (niacinamide)?
Nicotinamide (niacinamide) is the amide form of vitamin B3 — the flush-free alternative to nicotinic acid. Both are forms of niacin and share the same 6 authorised EU/UK health claims. Nicotinamide does not cause the niacin flush and converts efficiently to NAD via the salvage pathway. Food supplement — not a medicine.
✅ Does nicotinamide cause a niacin flush?
No — nicotinamide (niacinamide) does not cause the niacin flush. It does not activate the GPR109A prostaglandin receptors responsible for skin vasodilation. Even at 500mg, the vast majority of users experience no skin redness, tingling or warmth. This is the primary reason people choose nicotinamide over nicotinic acid.
Is nicotinamide the same as niacinamide?
Yes — nicotinamide and niacinamide are exactly the same compound (pyridine-3-carboxamide). They are two different names for the identical chemical substance — the flush-free amide form of vitamin B3. Completely interchangeable.
Nicotinamide vs Nicotinic Acid UK — What Is the Difference?
Nicotinamide = no flush.Nicotinic acid = causes the niacin flush. Both are forms of vitamin B3 with identical authorised EU/UK health claims. Nicotinic acid binds GPR109A receptors causing capillary vasodilation — nicotinamide does not. If you want the flushing form, see our B3 Niacin Nicotinic Acid Capsules.
What are the authorised health claims for nicotinamide?
Six authorised EU/UK claims: niacin contributes to normal energy-yielding metabolism · normal functioning of the nervous system · normal psychological function · reduction of tiredness and fatigue · maintenance of normal skin and mucous membranes · maintenance of normal mucous membranes.
What is the difference between nicotinamide, NMN and NR?
All three relate to the NAD synthesis pathway. Nicotinamide is the basic amide form of vitamin B3. NR (nicotinamide riboside) is nicotinamide plus a ribose sugar — a nucleoside that enters the NAD pathway at the NMN stage. NMN is the direct immediate precursor to NAD. NMN and NR enter the NAD pathway at later, more direct stages than nicotinamide. See our NMN Capsules range.
How much nicotinamide is 500mg vs NRV?
The EU/UK NRV for niacin is 16mg per day. Each capsule provides 500mg = 3,125% NRV — a high-strength dose. Consult a healthcare professional before high-dose use.
Are these capsules vegan?
Yes — 100% vegan and vegetarian. HPMC plant-derived capsule shell, no gelatin, no fillers, no binders.
Is nicotinamide available for wholesale?
Yes — bulk wholesale up to 1000 capsules per pack — one of the largest formats available from any UK supplement supplier. Suitable for health retailers, gyms, sports nutrition brands, supplement manufacturers and trade buyers. Contact us for trade pricing →
