Evidence-Based Pregnancy & Prenatal Supplement Guide
Essential nutrients from pre-conception through third trimester and nursing.
Evidence Summary (TL;DR)
Folic acid (400-600 mcg) is non-negotiable for neural tube defect prevention starting before conception. DHA (200mg+), Vitamin D3, Calcium, and Iron are crucial as pregnancy progresses. Avoid high-dose preformed Vitamin A (retinol).
Core Prenatal Supplement Protocol
Key nutrients recommended by ACOG and WHO:
Methylfolate / Folic Acid
400 - 600 mcg/dayPrevents neural tube defects and supports DNA synthesis
Timing: Pre-conception through 1st trimester
Algae DHA / Pure Fish Oil
200 - 300 mg DHA/dayFetal brain architecture and retina development
Timing: 2nd trimester through lactation
Vitamin D3
1000 - 2000 IU/daySupports skeletal development and immune regulation
Timing: Throughout pregnancy with meals
Calcium Citrate
1000 mg/day (split)Prevents maternal bone resorption and cramping
Timing: Bedtime or between meals (away from iron)
Safety Warnings & Interactions
- •Avoid high doses of preformed Vitamin A (retinol >3000 mcg RAE) due to teratogenicity risk.
- •Take iron and calcium at least 2 hours apart to prevent competitive absorption inhibition.
Frequently Asked Questions
Why choose methylfolate over standard folic acid?
Methylfolate (5-MTHF) is the active form of folate that bypasses the MTHFR enzyme pathway, ensuring effective cellular utilization regardless of genetic polymorphism.
