Second Trimester Nutrition Needs: Your Complete Guide
Quick Answer
Second trimester needs: +340 calories/day, 80g protein/day, increased iron (27mg) and calcium (1000-1300mg). Focus on balanced meals with variety. Energy typically returns during this trimester.
Introduction
The second trimester is often the sweet spot of pregnancy: the early nausea usually settles, your energy comes back, and food starts to appeal again. It is also when your baby begins growing quickly, so this is the moment to gently lift the quality of what you eat rather than simply the quantity. You only need a small increase in calories, but a real focus on protein, iron, calcium and healthy fats pays off now. Here is what your body is asking for and the easiest ways to give it.
Helpful pregnancy essentials
A few things expecting moms often find useful. Always check with your OB-GYN or midwife first.
The second trimester (weeks 14-27) is often called the 'honeymoon period' of pregnancy. Energy returns, morning sickness usually subsides, and your baby grows rapidly. Your nutritional needs increase significantly.
Calorie Needs
You need approximately 340 additional calories per day during the second trimester. Focus on nutrient-dense foods rather than empty calories.
Protein Requirements
Aim for 80g of protein per day (10g more than first trimester). Include:
- Well-cooked lean meats
- Low-mercury fish
- Eggs, dairy, legumes
Essential Nutrients
- Iron: 27mg daily (prevent anemia)
- Calcium: 1000-1300mg daily (baby's bone development)
- Folate: Continue 600-800mcg daily
- DHA: 200-300mg daily (brain development)
Meal Planning
Plan for 3 balanced meals + 2 snacks per day. Include variety across all food groups.

The second trimester is often when appetite returns and energy picks up, and it is also when your baby grows quickly and your blood volume expands. That combination pushes two nutrients to the front of the queue: iron, to make the extra blood you both need, and calcium, to build your baby's developing bones and teeth. Meeting them now helps prevent the tiredness and deficiencies that can otherwise creep in.
Iron-rich lentils and spinach become plant-powered staples, and pairing them with a squeeze of citrus boosts absorption, while calcium from pasteurised yogurt and milk supports bone growth. Salmon twice a week adds omega-3 DHA for brain development. A daily prenatal vitamin backs up your iron and folate intake, and a prenatal DHA supplement is a simple way to hit your omega-3 target if fish is not a regular feature.
- Iron: lentils, beans, lean red meat and spinach, paired with vitamin C
- Calcium: pasteurised yogurt, milk and fortified alternatives daily
- Omega-3 DHA: two servings of low-mercury oily fish a week
- Keep protein at every meal to support steady growth
- Continue a daily prenatal and stay well hydrated
This middle stretch is a wonderful window to build good habits while you feel your best. Nourish the iron and calcium bases and the rest of your plate tends to fall into place.
Common questions about second trimester nutrition
Which nutrients matter most in the second trimester?
Iron and calcium take priority as your blood volume expands and your baby's bones develop, alongside protein and omega-3 DHA.
How can I absorb more iron from food?
Pair iron-rich foods like lentils and spinach with a vitamin C source such as citrus or peppers, and separate them from tea or coffee.
How much calcium do I need while pregnant?
Around 1000 mg a day for most adults, achievable with pasteurised dairy or fortified alternatives across your meals.
Do I need extra calories in the second trimester?
Yes, but only around 300 to 340 extra calories a day, best spent on nutrient-dense foods rather than large portions.
