i got blood work and my iron was above the upper limit so its important to me to have no iron in my multi.
i use vitamine c as well as a multi.
im gonna start using the mens 1 a day like semper.
i also got cramps from multis, but what i would do is start taking it with food for a month, then i took it with a LARGE glass of water before and after, now i can take it with just a mouth full of water
try that see if it works.
