Prenatal vitamins vary in price, based on the size of the package, the brand, and the nutrients included. Options range from about $0.10 per day to up to about $2.50 per day. The options that are the most comprehensive, with most of the nutrients we recommend supplementing in high enough doses, are often more expensive. Some options are more expensive simply because they are made by boutique brands. The form of the supplement is also a factor. Our most expensive option is Needed's powdered prenatal, which may be helpful during periods of pregnancy when nausea makes it too difficult to swallow a pill. Our top pick is FullWell's Prenatal Multivitamin which comes out to about $1.67 per day—it contains optimal levels of almost all nutrients. But we do recommend taking an omega-3 supplement in addition, and, depending on your individual body and diet, you may also need an iron supplement. Our budget pick, Nature Made's Prenatal + DHA, is third-party verified, affordable. It is a one-pill-a-day option, and it contains some key nutrients, but it is also not nutritionally ideal. You may still save money by choosing this option and adding some individual nutrient supplements each day.
