I use one a day active women 50 plus. The main thing to check is try putting your vitamin in some vinegar. If it disolves in a few minutes it is good. If it doesn't it is not going to do you much good. I take this one because it does not have iron. I lean toward having to much iron, so doctor told me not to take anything with iron in it. These also do not cause the nausea for me that most do.
