Prenatal Vitamins: What to Take and When to Start
A guide to essential prenatal nutrients including folic acid, iron, and DHA for a healthy pregnancy.
Healthcare providers recommend starting prenatal vitamins at least one month before trying to conceive, ideally three months prior.
Folic Acid (400–800 mcg)
This B vitamin is critical for preventing neural tube defects. The neural tube forms in the first 28 days — often before you know you are pregnant.
Iron (27 mg)
Pregnancy increases blood volume by about 50%. Adequate iron prevents anemia and supports oxygen delivery to the baby.
DHA (200–300 mg)
This omega-3 fatty acid supports fetal brain and eye development, particularly during the third trimester.
Calcium & Vitamin D
Calcium (1,000 mg daily) supports bone development, while vitamin D (600 IU) aids calcium absorption.
Always consult your provider before starting any supplement regimen.
