<<Disclaimer: Verify this information before applying it to your situation.>> I have used the Twinlab Prenatal Vitamins for the last four years. They are good for pregnant and lactating women and since I have had two pregnancies and am lactating, they are a necessity. They are also lactose-free and rice-free (I am rice allergic.) Twinlab vitamins are notorious for being free of harmful substances... Jenny Rackley [log in to unmask]
