Thanks everyone for your help and advices.It took me one hour to cool down and all I had was 100 mg of the niacin.I bought this one by SOLARAY and it says the other ingredients are: whole rice concentrate including the germ and aloe vera gel.
I'll take it tomorrow after my breakfast and see if the reaction is a bit more subdued.I guess that's what a hot flash feels like!!When these are finished,I'll switch to the one you recommend Newport.
I found this link very informative:
