AI picks by need
For methylfolate, higher choline
Thorne Basic Prenatal (line)
It uses methylfolate and active B vitamins in a well-manufactured capsule.
Not for: People who want DHA included, since it needs a separate omega-3.
For whole-food style, gentle on stomach
MegaFood Baby & Me 2 (line)
It is designed to be taken with or without food and is often tolerated better during nausea.
Not for: Anyone who wants DHA and the prenatal in one product.
What the AI looks for in Prenatal Vitamins
- Folate
- At least 400 mcg folic acid (about 680 mcg DFE) daily, started at least one month before conception. This is the established dose for reducing neural tube defect risk.
- Iron
- Around 27 mg, the pregnancy RDA, unless your clinician says otherwise. Iron needs rise sharply in pregnancy, and many regular multis carry less or none.
- Iodine
- 150 mcg as potassium iodide. Iodine is essential for fetal brain development and is missing from many prenatals.
- DHA
- At least 200 mg, in the product or as a separate supplement. It supports fetal brain and eye development and is often omitted to save space.
- Preformed vitamin A cap
- Keep total preformed retinol under 3,000 mcg RAE (10,000 IU), and prefer beta-carotene. Excess preformed vitamin A is teratogenic.
Brands that matter
- Nature Made: USP Verified prenatal with DHA.
- Thorne: Methylfolate-based prenatal.
- MegaFood: Food-based prenatal, gentle on the stomach.
- Ritual: Minimalist prenatal with DHA, but it relies on diet for some nutrients.
- Garden of Life: Vegan and whole-food prenatal options.
What to avoid
- Gummy prenatals as your only prenatal, because they typically lack iron
- Prenatals with high preformed vitamin A
- Adding a separate vitamin A or high-dose herbal blends without medical advice
Questions
Folic acid or methylfolate?
Folic acid is what the neural-tube research used and works for most people, while methylfolate is a reasonable alternative and does not need to be sought out unless your clinician advises it.
