I have not noticed feeling warm after the vitamin. I dont believe they contain anything besides the standarf vitamins and minerals, its just a mens one a day vitamin. [/quote]
Intredasting. I was betting on niacin (B3). While the main response to high niacin intake seems to be the “niacin flush” (warmness/ruddiness alongside a slight tingling in the face), headaches are not hugely uncommon. Given that many multis love to stack their B complexes well above the RDA, this jumped out as the likely culprit.
Have you used any other brands prior to this one? If so, any issues?[/quote]
I have switched brands a few times, had a GNC mega men, Target brand, and the 1 a day.
Basically all have the same ingredients though.
I’d love to take a multi vitamin but its not worth it as these headaches are dang near incapacitating.
Worth trying: Pure Essence Labs’ One ‘n’ Only Multi.
Everything in it is food-based, so it’s very bioavailable.
It’s priced in line with other multis, and some health food stores carry it.
