    Added niacin carefully because I wanted to see how it fitted around training. it gives me a bit of warmth and seems to suit pre workout days, but I like that it is still just a plain vitamin b3 capsule rather than a flashy blend

    Good to see a flushing Niacin at last!
    It is excellent to relax nerves in the morning or before bedtime (2 gr);
    excellent before sports when u have no time to warm up,get some and wait for the flushing,this way no injuries!
    Cold weather?Flushing effect may help by his warmness…

The formula in focus

Know your niacin. Know the flush.

Crown Supplements uses nicotinic acid, the form of vitamin B3 associated with a niacin flush. The formula also contains fenugreek and liquorice root, with the niacin amount stated separately.

The ingredient

What to expect

A temporary warm, red or tingling feeling, sometimes with itching, is a familiar effect of flushing niacin. How noticeable it feels varies between people.

The formulation

Vitamin B3 support

Niacin contributes to normal energy-yielding metabolism, helping your body release energy from food.

Getting started with Niacin Flush

Help keep the flush manageable.

Simple changes to how you take niacin can make the flush less noticeable.

01

Take with a meal

Take niacin with food rather than on an empty stomach. This can soften the flushing sensation, although it may not prevent it completely.

02

Watch the timing

Avoid alcohol, hot drinks and spicy food around the time you take niacin, as these can intensify flushing.

03

New to niacin?

Agree a low starting dose with a pharmacist or doctor. Each capsule contains 371mg, so a lower-strength product may be needed initially. Any dose increase should be gradual and professionally guided.

Your questions answered

Frequently asked questions.

What are Niacin Flush Vitamin B3 capsules?

Crown Supplements Niacin Flush capsules provide 371mg nicotinic acid per capsule, alongside fenugreek and liquorice root. Nicotinic acid is the flushing form of vitamin B3.

Are niacin and vitamin B3 the same?

Niacin is another name for vitamin B3. This product supplies it as nicotinic acid, which can cause flushing.

How much niacin is inside each capsule?

Each capsule contains 371mg niacin as nicotinic acid.

What does 2,319% NRV mean?

NRV means Nutrient Reference Value. One capsule supplies approximately 2,319% of the adult reference value for niacin; a higher percentage does not mean greater benefit.

What is a niacin flush?

Nicotinic acid can temporarily widen small blood vessels near the skin, causing warmth, redness, tingling or itching. This is the recognised niacin flush and usually settles on its own. Its intensity and duration vary.

Should these niacin capsules be taken with food?

Yes. Take them with a meal rather than on an empty stomach. Avoid alcohol, hot drinks and spicy food around the same time to help reduce flushing.

What should new users know about niacin flush?

Flushing can be more noticeable when you first start and may become milder with regular use. One capsule already supplies 371mg, so ask a pharmacist or doctor about a suitable starting strength. They can advise on any gradual increase; flushing tolerance alone does not establish a safe dose.

How should the Vitamin B3 capsules be taken?

Take with a meal and water, following your product label and the dose agreed with your pharmacist or doctor. Do not increase the dose simply to produce a stronger flush.

Which other ingredients accompany the niacin?

Fenugreek and liquorice root. Their weights are not included in the stated niacin amount.

Which capsule shell is used?

The formula uses HPMC capsules made from hypromellose.

Are fillers, binders or machine flow agents added?

No fillers, binders or machine flow agents added by Crown Supplements.

Can I buy Niacin Flush capsules in the United Kingdom?

Yes. Crown Supplements supplies Niacin Flush Vitamin B3 Capsules throughout the United Kingdom. Choose 90, 180 or 270 capsules.

Is this the same as flush-free niacin?

This product uses flushing nicotinic acid. Nicotinamide (niacinamide) and inositol hexanicotinate are different forms that do not usually cause the niacin flush. Check the ingredient name when comparing products.
