If we talk about pregnancy a lot at Ritual—a lot, a lot—it’s only because we emphatically believe that knowing what’s going on in the body is as crucial as taking a great prenatal multivitamin.

The Question: How soon should someone start taking a prenatal multivitamin?

The Question: What’s the deal with folic acid?

The Answer: Folic acid is a synthetic form of folate, a B-vitamin that helps support neural tube development and energy-yielding metabolism. (And FWIW, it’s still crucial when not expecting.) The thing is, up to one-third of people have a genetic variation that makes it difficult to efficiently utilize folic acid—which is why we opt for methylated folate in Essential Prenatal.*

The Question: Do I seriously need to change my diet?

The Answer: It depends. If you try to eat nutritiously most of the time anyway, then chances are you won’t have to make any drastic changes for your pregnancy—outside the obvious, of course.

Either way, it can’t help to get the full scoop on what to aim for.*

The Question: What if I’m vegan?

The Answer: For starters, it’s definitely worth seeking out a vegan-friendly prenatal multi. While experts say that it’s possible to meet nutrient needs of pregnancy on a plant-based diet, we think it’s important to focus on three nutrients in particular: omega-3 fatty acids, vitamin B12, and iron, which can be a bit tougher to consume on a vegan or vegetarian diet. (We include all three in Essential Prenatal, which is vegan-friendly.) Aside from that, you might want to check in with your doc to come up with an eating plan you both feel great about.*

The Answer: From pregnancy-related morning sickness to fatigue, the first trimester can definitely make people feel a little “off” at times. The good news?

(Reaching for a prenatal multivitamin housed in a delayed-release, gentler-on-the-stomach capsule design never hurts, either.)*
