Your formula at a glance
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.
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.
Vitamin B3 support
Niacin contributes to normal energy-yielding metabolism, helping your body release energy from food.
Help keep the flush manageable.
Simple changes to how you take niacin can make the flush less noticeable.
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.
Watch the timing
Avoid alcohol, hot drinks and spicy food around the time you take niacin, as these can intensify flushing.
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.

Have to be careful to take them with food otherwise experience the tingles but they certainly boost energy.
I’ve been taking the Niacin Flush for months now and it never fails me. It’s my favourite brand by far.
I had a niacin flush i went extremely red and itchy so i had to stop taking them if you don’t have a reaction like me it will be a very good product
Excellent product. I will definitely re order before it runs out.
Superb finally found Niacin which flushes, no added fillers. Happiness
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…
B3 Vitamins really important for bodily health fast delivery
niacin was part of sorting my b vitamin basics. nothing flashy, but i feel a bit more steady in the afternoons since adding it. arrived quick too
niacin was just part of tightening up my b vitamins. I don’t notice a huge kick, but I do feel more level in the mornings
