🔥 STRONG SKIN FLUSH — READ BEFORE USE
This product WILL cause a strong skin flush. Redness, tingling, heat and itching across the face, neck and chest, sometimes with headache or dizziness. It begins 10–20 minutes after a dose and usually passes within 30–60 minutes. It is not an allergic reaction, but it is intense and it surprises people who are not expecting it.
Stated serving: 50mg once daily. Do not exceed 500mg in any 24 hours.
NEVER take 1,000mg or more in a day without medical supervision. At 1,000mg and above, nicotinic acid is a therapeutic dose used to manage blood lipids under a doctor's care with liver function monitoring. Adverse effects — including liver injury, low blood pressure and disturbed blood glucose — become markedly more common above this level.
Nicotinic acid and nicotinamide are not interchangeable. They are both Vitamin B3 but behave completely differently — nicotinamide does not flush at all. Never apply a figure for one to the other. Adults 18+ only. Not for use in pregnancy or breastfeeding.
🔥 About the niacin flush: flushing is dose-related. Roughly 5% of people flush at a single 50mg dose and around 50% at 100mg, with intensity climbing from there. For reference, the upper intake level set for supplemental nicotinic acid is 10mg per day — a conservative figure derived from flushing rather than from toxicity, but worth knowing when you choose your amount. If you want Vitamin B3 with no flushing at all, use our B3 Nicotinamide Powder (non-flush).
📋 Food Supplement: B3 nicotinic acid powder is a food supplement — not a medicine. Vitamin B3 authorised claims apply as stated below. All other content is educational background, not a product claim. Consult a healthcare professional before use if taking any medication or under medical supervision.
⚡ Quick answer
Nicotinic acid is the flushing form of vitamin B3, also called niacin. Charge Products supplies it at 99.5–100.5% assay to BP standard in ten sizes from 50g to 25kg, priced from £6.99 — around 0.7p per 50mg serving at the smallest size.
Stated serving 50mg once daily. Ceiling 500mg in 24 hours. Never 1,000mg or more without medical supervision. Around 5% of people flush at 50mg and around 50% at 100mg. Nicotinamide is the non-flushing form and has a far wider margin.
All six authorised GB niacin claims apply at this serving, which delivers 313% NRV. Single ingredient — no fillers, binders or excipients. Adults 18+ only.

🔥 B3 Nicotinic Acid Powder UK — What Is Niacin?
Looking to buy nicotinic acid powder UK from an established supplier? Charge Products supplies pure B3 nicotinic acid powder — the flushing form of Vitamin B3, commonly known as niacin. Single ingredient, assayed at 99.5–100.5% on a dry basis to BP standard, no fillers, binders or excipients.
Vitamin B3 exists in two supplement forms and they are not interchangeable. Nicotinic acid (this product) flushes above roughly 30–50mg and has an upper intake level of 10mg per day. Nicotinamide does not flush and its upper level is 900mg per day. Same six authorised claims, intake figures ninety times apart. That is the most misunderstood thing about vitamin B3, and it is why this page states a serving and a maximum rather than leaving you to guess.
Supplied in a resealable food-grade foil bag by Charge Products — UK supplement supplier since 2016, 163,000+ verified sales, 5 Star Food Hygiene Rating from Southend-on-Sea City Council. UK stock, same-day dispatch before 3:30pm Mon–Fri.
📏 Serving, Nutrition Declaration & Upper Intake Level
| Per 50mg serving | Amount | % NRV |
|---|---|---|
| Niacin (as nicotinic acid) | 50 mg NE | 313% |
NRV = Nutrient Reference Value. Niacin NRV is 16 mg NE. A serving must provide at least 15% NRV (2.4 mg) to carry the authorised Vitamin B3 claims — this serving provides 313%.
Choosing your serving — the honest numbers
We state 50mg once daily. That is the point at which roughly 5% of people begin to flush, so it is a sensible place to start if the flush is what you are after and a manageable one if it is not.
Two reference points. The published upper intake level for supplemental nicotinic acid is 10mg per day — conservative, derived from flushing rather than organ toxicity, which is why almost every product on the market sits above it. At the other end, 1,000mg and above is prescription territory, used for lipid management with liver function monitoring.
Our ceiling is 500mg in any 24 hours. We are not going to publish dosing guidance above that, because at those intakes this stops being a food supplement question and becomes a medical one.
✅ Six Authorised GB Nutrition Claims — Vitamin B3 (Niacin)
All six authorised GB claims for niacin apply at this serving, in their exact approved wording:
⚡ Niacin contributes to normal energy-yielding metabolism
🧬 Niacin contributes to the normal functioning of the nervous system
🧠 Niacin contributes to normal psychological function
💧 Niacin contributes to the maintenance of normal mucous membranes
✨ Niacin contributes to the maintenance of normal skin
😌 Niacin contributes to the reduction of tiredness and fatigue
Authorised under Regulation (EC) No 1924/2006 as retained in UK law. These are maintenance-of-normal-function claims and must not be read as anything more. All other content on this page is educational background only — not additional product claims.

🔥 The Niacin Flush — What It Is and What It Signals
The niacin flush is the single best-known effect of nicotinic acid, and the reason many people search for flushing niacin specifically. Here is what it actually is — and what it tells you.
⏱ What happens
- Redness, tingling and warmth on face, neck and chest
- Begins 10–20 minutes after a dose, subsides within 30–60 minutes
- Caused by prostaglandin-mediated dilation of small skin capillaries
- Not an allergic reaction
- Can be accompanied by headache, dizziness or a drop in blood pressure
📊 At what intake
- 10 mg — the published upper intake level; no flushing
- 50 mg — our stated serving; around 5% flush
- 100 mg — around 50% flush
- 250 mg+ — flushing in most people, often strong
- 500 mg — our stated ceiling; do not exceed
- 1,000 mg+ — therapeutic dose. Medical supervision only
The honest position: the flush itself is uncomfortable rather than dangerous, and many people take nicotinic acid specifically for it. What we will not do is publish a dosing ladder for climbing past 500mg a day. Above that you are into territory where adverse effects become common, and at 1,000mg and above nicotinic acid is a therapeutic dose used for lipid management under medical supervision with liver function monitoring. Sustained intakes at gram level carry a documented risk of liver injury. If that is what you are looking for, it is a conversation for your GP and not a product page.
🚫 Who Should Not Take Nicotinic Acid Powder
- Anyone under 18. The upper level for 15–17 year olds is 8mg per day and this product is not intended for them.
- Pregnancy and breastfeeding — do not use.
- Liver problems — sustained high intakes of nicotinic acid are associated with liver injury.
- Gout or raised uric acid — nicotinic acid can raise uric acid levels.
- Diabetes or impaired glucose control — nicotinic acid can affect blood glucose.
- Peptic ulcer or active gastritis.
- Low blood pressure, or if you are prone to dizziness or fainting.
- Regular alcohol consumption above modest amounts — the combination increases the burden on the liver.
- On prescribed medication, particularly statins or blood pressure medication — speak to your GP first.
If a doctor has prescribed high-dose niacin for you, follow their instructions and not this label. Prescribed niacin is a different product used under medical supervision.

❓ Frequently Asked Questions — B3 Nicotinic Acid Powder UK
How much nicotinic acid powder should I take per day?
Our stated serving is 50mg once daily, providing 50mg niacin — 313% NRV. Do not exceed 500mg in any 24 hours. For reference, the published upper intake level for supplemental nicotinic acid is 10mg per day, a conservative figure derived from flushing rather than toxicity. Nicotinic acid and nicotinamide have completely different intake figures, so one must never be applied to the other.
Why is the upper level for nicotinic acid so much lower than nicotinamide?
Because the two forms behave differently. The upper level for supplemental nicotinic acid is 10mg per day and was set on the basis of skin flushing. For nicotinamide it is 900mg per day — ninety times higher — because nicotinamide does not flush. Same vitamin, very different figures.
What is the niacin flush?
Redness, tingling and warmth across the face, neck and chest, beginning 10–20 minutes after a dose and usually subsiding within 30–60 minutes. It is caused by prostaglandin-mediated dilation of small skin capillaries and is not an allergic reaction. But it is a signal that intake is well above the reference level — roughly 5% of people flush at a single 50mg dose and around 50% at 100mg, against a 10mg per day upper level.
How much do I need to flush?
Around 5% of people flush at our stated 50mg serving and around 50% at 100mg, with intensity climbing from there. Sensitivity varies a lot between individuals, so start at 50mg and see how you respond before considering more. Do not exceed 500mg in any 24 hours. And never take 1,000mg or more in a day without medical supervision — at that level nicotinic acid is a therapeutic dose used for lipid management under a doctor's care, and adverse effects become markedly more common.
What is the difference between nicotinic acid and nicotinamide?
Both are Vitamin B3 and both carry the same six authorised GB claims, but they are not interchangeable. Nicotinic acid flushes and has a 10mg upper level. Nicotinamide does not flush and has a 900mg upper level. If you want Vitamin B3 without flushing risk, nicotinamide is the form to choose.
Is nicotinic acid the same as niacin?
Yes — the same compound. Nicotinic acid is the chemical name; niacin is the common name, used particularly in the US. Both refer to the flushing form of Vitamin B3, distinct from nicotinamide (niacinamide), the non-flushing form.
What are the authorised Vitamin B3 claims?
Six authorised GB claims for niacin: normal energy-yielding metabolism · normal functioning of the nervous system · normal psychological function · maintenance of normal mucous membranes · maintenance of normal skin · reduction of tiredness and fatigue. A serving must provide at least 15% NRV to carry them; ours provides 313%.
Who should not take nicotinic acid powder?
Anyone under 18. Do not use in pregnancy or while breastfeeding. Speak to your GP first if you have liver problems, gout, diabetes, a peptic ulcer or low blood pressure, or if you take prescribed medication — particularly statins or blood pressure medication.
What is the purity?
99.5–100.5% nicotinic acid on a dry basis, to BP pharmacopoeia standard. Single ingredient, no fillers, binders or excipients. Loss on drying max 1%, sulphated ash max 0.1%. Batch certificate of analysis available on request.
Do I need scales to measure it?
Yes. A 50mg serving cannot be measured with a spoon or judged by eye, and the difference between 50mg and 500mg is invisible in a spoon. Digital milligram scales reading to 0.001 g are required. No scoop is supplied because no scoop is accurate enough at this weight.
Is nicotinic acid powder vegan?
Yes. Synthetically produced from 3-cyanopyridine, with no animal-derived material. Suitable for vegans and vegetarians. The manufacturing site handles none of the 14 declarable allergens.
Do you supply nicotinic acid powder wholesale?
Yes — bulk to 25kg for supplement brands, capsule fillers, tablet manufacturers, food fortification and contract packers. UK-held stock, same-day dispatch. Formulators should work to the 10mg per day upper intake level when setting inclusion rates.
How should it be stored?
Sealed, in a cool dry place away from moisture and direct sunlight. Shelf life is a minimum of three years from manufacture in the original sealed packaging.
Is this product a medicine?
No — a food supplement only. High-dose nicotinic acid is used medicinally under prescription for lipid management, but that is a different product at a different dose under medical supervision. Nothing on this page is medical advice.
