This is the simple form of Niacin that does flush the body and is good to use with detoxing combined with the sauna

Niacin Flush May Occur!

Posted by iHerb Customer on Oct 19, 2017 | Verified Purchase

I took this product for the very first time before I was due to leave for work and I would NOT recommend doing this as I had a HUGE Niacin Flush reaction occur all over my body! So begin with perhaps 1/4 of a tablet and do it at a time you may not have to leave the house for an hour! In saying that, hot flush left body within 40 minutes - so all good!

Thanks for your feedback!

Powoduje uderzenia gorąca :)

Posted by iHerb Customer on Mar 22, 2017 | Verified Purchase

Rzeczywiście niacyna zażywana nagle w dużej dawce i popijana gorącymi napojami powoduje efekt "flush". Jednak stopniowe podawanie małych dawek (ja dzieliłam tabletkę na 4 i po ćwiartce 3xdziennie, stopniowo zwiększając dawkę) powoduje niewielkie zaczerwienienie skóry. Jeśli chodzi o działanie uspokajające i wywołujące senność wieczorem, to takie jest. O innych zaletach niacyny, opisanych w książce "Niacyna w leczeniu" nie mogę się wypowiedzieć, gdyż nie mam wiedzy na ten temat. Jeśli jednak jej działanie, oparte na długotrwałym regularnym zażywaniu, takie jest, to warto ją brać. Na razie biorę 300 mg dziennie podzielone na trzy dawki. W każdym razie nie zaszkodzi spróbować :)

Thanks for your feedback!

Love it

On my 2nd bottle - works well to relax me to fall asleep - however take it within 1 hour after dinner or you will get that flush!! I have found on the odd occasion I have the flush eating a slice of bread or any carbohydrates reduces the intensity and duration of the flush - a protein snack or fruit/vegetable snack does nothing to cut the flush - I will continue to use this product
