While flintsones are somewhat lacking in everything you need, You CAN use them with a folic acid supplement, this is what the OB/GYN that I see, and work for, tells our patients who are unable to tolerate a PNV. The first reply is correct, though, in that they are not intended for use by adults, so you need to take 2 of them, with a folic acid tablet. She is also correct that OTC PNV's contain everything a Rx does, and they are available at any drugstore or even at WalMart or discount stores. They are cheap, too! Talk to your OB about what he or she feels is right for you, though!
