Hands-on review

A single daily softgel with DHA — simple and cheap. It scores strongest on one pill/day; the main trade-off is folic acid (not methylated). A confident prenatal vitamin pick for the right shopper.

A single daily softgel with DHA — simple and cheap. Here is how the One A Day Prenatal 1 held up against the rest of our prenatal vitamins rotation, and where it fits.
On our six-axis scale the One A Day Prenatal 1 averages 8.5/10, with its highest marks for one pill/day and inexpensive. That makes it a dependable everyday prenatal vitamin rather than a one-trick option.
Pros that stood out: One pill/day, Inexpensive. Trade-offs to know about: Folic acid (not methylated).
Certification: USP-tested ingredients. We weight safety heavily in this category, and the One A Day Prenatal 1 clears the bar; build quality is in line with its $14–$16 price.
If one pill/day is your priority, the One A Day Prenatal 1 is an easy recommendation. If folic acid (not methylated) matters more, compare it against the other picks in our best prenatal vitamins guide.
What parents tell us most often: one pill/day.
