Breastfeeding is a beautiful, bonding experience—but let’s be honest: it’s also intense. Your body is working overtime to produce nourishing milk while recovering from pregnancy and birth. And amidst the nappy changes, late nights, and new routines, it’s easy to forget just how much your body still needs.
That’s where supplements can step in—not to replace a healthy diet, but to gently fill in the gaps. Because here’s the truth: when you feel well, it’s easier to care for your little one.
Why your nutrient needs remain high
Breastfeeding increases your daily energy and nutrient requirements—sometimes even more than pregnancy itself. Producing breastmilk takes a lot of energy—around 20 to 25% of your body’s resting energy, depending on how much milk you make and your overall nutrition. That’s even more than what your brain uses (about 20%). No wonder so many mums feel exhausted—your body is doing some serious behind-the-scenes work.
It also draws heavily on key nutrients like calcium, iron, iodine, and omega-3s. And if you’re not managing to eat well—maybe you're skipping meals or reaching for whatever’s quick and easy—you’re not alone. But it’s important to know that while your breastmilk will still provide for your baby, it often comes at a cost to your own body. Your system will draw from your nutrient stores to keep the milk nourishing, which can leave you feeling run-down or depleted over time. Taking care of your own nutrition is just as important now—it’s how you keep giving from a full cup.
Top tip: Nutrient needs vary depending on your BMI, activity level, and where you are in your breastfeeding journey. Want to know your personal daily requirements? Use this helpful calculator from the USDA:

Top 4 Supplements to support breastfeeding women
1. A postnatal multivitamin
A specially formulated postnatal multivitamin takes the pressure off—no need to juggle different bottles or second-guess what you might be missing. It brings together just the right amounts of key nutrients like vitamin D, B12, iron, iodine, and calcium, all in one convenient daily dose to support you while you nourish your baby.
- Try: Wild Nutrition Breast-Feeding Complex – thoughtfully formulated to support your energy, recovery, and milk quality with nutrients in their most absorbable forms.
- Iron – Often depleted after childbirth, iron supports energy and immune function. Vegan and vegetarian mums may need more.
- Calcium – Essential for healthy bones, circulation, muscle function, and the nervous system.
- Magnesium – Helps deactivate adrenaline (a stress hormone that can interfere with milk production) and supports restful sleep.
- Vitamin B12 – Your breastmilk reflects your B12 levels. It’s vital for energy and your baby’s brain development, especially for mums on a plant-based diet.
- Vitamin D – Important for your mood, immunity, and calcium absorption. Most breastmilk is low in vitamin D unless you supplement.
- Iodine – It’s essential for making thyroid hormones (T3 and T4), which play a big role in your baby’s growth and brain development.
