One a Day or Centrum is fine. I try to get the most bang for my buck by getting something with the trace minerals and any extra nutrients they sometimes throw in. But I'm not going to pay scads for it. I usually use
Puritan whose value you can't beat.
Part of what I was getting at with the extras, btw, goes into what Hrdgain was saying. When you get something like animalpak you are paying way too much for extra of everything and then the additional things that they choose for you. But if you pay less then you can make a concious choice for the things you made need extra of. You may not know exactly what you are "defiencient" in but it makes more sense to say, "as a bodybuilder I probably need more of this and that particular thing.
For example lots of people choose to take a multi vitamin mineral but also have extra vitamin C and sometimes E for post workout. It doesn't have to be used for post but it's a time that makes sense. There are many many reasons why someone would want to do this but in any case it represents a stategic decision. Using your money to it's utmost for specific purposes. Especially if you were to only use it for post workout and relying on the regular multi to ensure your daily allowance.
Other things bodybuilder's could need more of is magnesium and zinc. And that is just the vitamin/mineral end of it. Similar things go with aminos too as we all know. I'd rather decide exactly what extra aminos I want rather than paying my surplus money for a vitamin that has a little of this and a little of that thrown in.
With herbs you have to be expecially careful. Ginseng, for instance, although very popular, has never been shown to be the adaptogen it's hyped to be. And gyseng is not gynseng is not gynseng. The quality gynseng is VERY expensive. I can almost guarantee that what is in animal pak is not high grade stuff. And even if it was, again, your probably paying for something that serves very little purpose.
