Week 3 of pregnancy: nutrients to focus on

Week 3 of 42 First trimester Source-backed Educational only

Short answer

In week 3, Niva puts folate and hydration first in its food ideas, with vitamin B6 and iron alongside. This is a food prompt, not a new target: the daily reference amounts for pregnancy stay the same from week to week.

Main focus in week 3

Folate. Food examples from ACOG: fortified cereal, enriched bread and pasta, peanuts, dark green leafy vegetables, orange juice, beans. Read more: Folic acid and folate in pregnancy
Hydration. Read more: Week 11 Food Focus: Hydration

Also in view

Vitamin B6. Read more: Pregnancy nutrients by week and trimester
Iron. Food examples from our Read on iron: beans, lentils, iron-fortified cereals, meat, poultry, seafood, tofu, spinach, and pumpkin seeds. Read more: Iron during pregnancy

Why these nutrients

Folate has an established pregnancy RDA; this week prompt keeps folate-rich foods visible. Niva uses the same focus for weeks 1 to 4.
