Do you take one? What kind? Do you feel it helps or do you take it because a doctor or someone told you to/prescribed it?

I'm trying to take "New Chapter Every Woman" which I found at my health food store.

I don't take them very consistently. I've been trying to get good vitamins that don't mess up my stomach, or intestines, or smell/taste bad, etc. These seem to be okay in that regard but they're supposed to be taken 3 a day and I'm lucky if I take that may a week
