I take GNC Women's Ultra Mega Energy and Metabolism. The Ultra Mega part always make me laugh a little bit for some reason. Like I said, I haven't seen much of a difference in how I feel before I started taking them, but winter generally hurts my energy levels, so maybe it would be worse if I wasn't taking them. My boyfriend takes the same GNC vitamin in the Men's, and he swears he feels a difference when he takes them, so there ya go. Before that, I took Women's Centrum Ultra. It's quite a bit cheaper, and from what I know, they're supposed to be good vitamins.
I would read up on what kind of vitamins build up in the body (that is, one's that if you have extra of, you don't just pee out) and make sure you don't overdo it on those vitamins, because it IS possible to get too much of certain vitamins in your system. That's why I feel like a multi-vitamin is a good place to start.
With the GNC vitamins I take now, I take both of my pills in the morning on a FULL STOMACH. I about puke if I take a vitamin and haven't eaten. You can take the two pills at separate times in the day, however.
