Best? no.
Decent? sure.
a multivitamin isn't anything amazing. Buy one that doesn't have a hard 'candy' shell around the outside, and isn't full of fillers and preservatives.
One should be sufficient. Remember, the main purpose of a vitamin supplement is to supplement your normal vitamin intake from whole foods. Its like insurance...you may not actually 'need' it, but you take it anyways just in case.
