I used to regularly take a multivitamin, and then kind of slacked off for awhile. I have recently started back on them (about a month ago) and I am AMAZED at the difference I see. I look less tired, I feel less sluggish, my nails are stronger, there's a bit of color in my perpetually fair skin...it's one of those "DUH!" kind of things, but it really does surprise me the difference I see and feel. I think especially when we are trying to lose weight, it can be hard to make sure we get everything we need through our food (although that's the best way). If anyone is looking to take one, I recommend Women's Once-A-Day Multi.
