Folic acid supplementation should begin before conception, because the neural tube closes within the first four weeks — often before pregnancy is confirmed. Iron, vitamin B12, vitamin D, iodine and protein all matter, and everything here belongs alongside antenatal care rather than in place of it.
Why the timing is before, not after
The neural tube closes by around day twenty-eight after conception, frequently before a woman knows she is pregnant. Folic acid supplementation is therefore recommended from before conception — ideally for three months beforehand.
Food folate from greens and pulses is worth having and is not sufficient on its own for this purpose. The supplement is the recommendation, and the dose is your doctor’s to set, since it is higher where there is a relevant history.
Is this what is happening to you?The two-minute check further down asks four questions and shows the result immediately. No email, no call.
Take the 2-minute checkWhat else matters in those months
Several of these are commonly low in Indian women before pregnancy, which is the argument for checking rather than assuming.
- Iron. Requirement rises substantially in pregnancy, and starting with depleted stores makes deficiency near-certain. Ferritin is worth checking beforehand.
- Vitamin B12. Frequently low in vegetarian diets and important for neurological development.
- Vitamin D. Widely deficient, and relevant to fetal bone development.
- Iodine. Needed for fetal brain development. Iodised salt is the main source, which is a reason not to switch away from it.
- Protein. Requirement rises through pregnancy, and vegetarian diets often start below the mark.
- Calcium. Where intake is inadequate, the mother’s own bone supplies the shortfall.
2-minute check
Why are you so tired?
Four questions. Fatigue nearly always has a findable cause.
How much do you sleep, and how well?
Any hair fall, breathlessness on stairs, or heavy periods?
Do you crash in the afternoon?
Any low mood or difficulty concentrating?
No obvious driver from these answers
If it persists, thyroid, ferritin and vitamin D are the sensible first tests.
There are likely contributors here
Ferritin, thyroid and vitamin D between them explain most persistent fatigue.
Several contributors appear to be present
This is worth testing properly rather than pushing through. All three common causes are treatable.
This check is an indication, not a diagnosis. It does not replace medical advice.
The first trimester in practice
Nausea makes the theoretical ideal impractical for many women. Small frequent meals, dry carbohydrate before getting up, ginger, and avoiding strong cooking smells all help. Cold food is often easier than hot.
If very little stays down, eat what does. Continuity matters more than composition during this phase, and the prenatal supplement covers more of the gap than people expect. Severe and persistent vomiting is hyperemesis and needs medical care rather than dietary advice.
What to avoid, and what we will not do
Avoid alcohol entirely, unpasteurised dairy, raw or undercooked eggs and meat, high-mercury fish, and papaya in the forms traditionally cautioned against. Limit caffeine to around 200 mg a day. Discuss all existing medicines and supplements with your doctor, including ones bought without a prescription.
We do not manage pregnancy and we do not give antenatal advice. Nutrition support in pregnancy works alongside your obstetrician, and where the two ever appear to conflict, your obstetrician is right.
In short
Questions we are asked
Do I need to eat for two?
No. Energy requirement rises modestly, and mostly in the second and third trimesters. Protein, iron, folate and calcium requirements rise proportionally more than energy does.
Is papaya unsafe in pregnancy?
Unripe papaya contains latex that has traditionally been cautioned against. Ripe papaya is generally considered fine. Follow your obstetrician’s guidance over any general list, including this one.
