When should I start taking prenatal vitamins?
Ideally 1–3 months before conception, since the neural tube forms in the first weeks. If you’re already pregnant, start as soon as you can — it’s never too late to benefit.
Are gummy prenatals enough?
They’re better than nothing and easier on nausea, but most gummies contain little or no iron and sometimes less folate. You may need a separate iron supplement — ask your provider.
