Prenatal Stack
The core nutrients obstetricians prioritise in pregnancy.
Strong stack — well-matched with minor gaps.
What's in this stack
- Prenatal Multivitamin7/10 evidence
One ingredient carries almost all the proven benefit: periconceptional folic acid prevents neural tube defects, at a level of certainty matched by few interventions in medicine. The rest of the formula is far less proven — and the landmark trial that established the folate effect found its other seven vitamins did nothing.
Typical dose: 1 serving daily as labelled. The verified folic acid evidence rests on 400-800 mcg daily started before conception
- Methylfolate6/10 evidence
Bioactive folate that bypasses MTHFR conversion — critical for the 30-40% of people with gene variants affecting mood and methylation.
Typical dose: 400-800mcg daily
- Iron9/10 evidence
Essential mineral for oxygen transport and energy production — critical for those with deficiency, especially women and athletes.
Typical dose: 18-45mg elemental iron for deficiency (varies by severity)
- Omega-39/10 evidence
Essential fatty acids critical for brain health, mood regulation, and reducing inflammation throughout the body.
Typical dose: 2-3g combined EPA+DHA daily
- Choline6/10 evidence
Precursor to acetylcholine and phosphatidylcholine — critical for memory, liver function, and cell membrane integrity.
Typical dose: 250-500mg daily (varies by form)

The grade above measures how well this stack covers its goals — it does not account for these.
- Prenatal Multivitamin + Iron (moderate)
Excess iron intake with no additional benefit for most people, and more of the GI side effects (constipation, nausea) that cause people to stop taking the prenatal at all. Genuinely relevant only where anaemia has been diagnosed.
Check the prenatal label first. Add standalone iron only if your clinician has diagnosed iron deficiency and specified the dose — do not layer it by default.
