Which supplements are useful while breastfeeding?

Four nutrients come up most often: iodine, vitamin D, DHA (an omega-3) and, for some mothers, iron or B12. None of these is a substitute for a varied diet, and your clinic or doctor should review anything you add, because small amounts reach breast milk.

How much iodine do you need?

The US recommended intake for breastfeeding women is 290 mcg a day, up from 150 mcg before pregnancy. US thyroid and paediatric bodies suggest a daily multivitamin or prenatal containing 150 mcg of iodine, because many products contain none. South Africa requires table salt to be iodised, which helps, but pink, sea and Himalayan salts are usually not iodised, and many mothers cut back on salt. Check the label of any multivitamin for iodine, since several local products do not state it in the information we reviewed.

What about vitamin D?

The usual adult intake is about 600–800 IU a day, and the EFSA upper limit is 4 000 IU (100 mcg) a day. If you get little sun, cover up, or have darker skin, a 1 000 IU supplement is a reasonable conversation to have with your clinician. In October 2026 the Dis-Chem Gold Vitamin D3 1 000 IU was R160 for 60 tablets at Dis-Chem Living Fit, about R2.67 a day. Products that add vitamin K2 contain vitamin K, which matters if you take warfarin.

Should you take omega-3 for DHA?

DHA contributes to infant brain development, and your milk DHA reflects your intake. Eating oily fish such as sardines, pilchards or salmon trout twice a week is the food-first route. If you rarely eat fish, a DHA-rich supplement is an option. The Real Thing Mega Omega Supreme lists 290 mg DHA per capsule, so one capsule a day costs about R5.65 at R339 for 60 (Faithful to Nature, October 2026, our calculation). The label dose is 2 capsules, which doubles that. Choose a purified product, avoid it with a fish allergy, and see our omega-3 comparison. Algae-based DHA is the option for vegans.

Do you need iron or B12?

Only if tested. Blood loss at birth can leave iron low, but supplementing without a result can cause constipation and, rarely, harm. Vegan and vegetarian mothers should talk to a dietitian about B12, because breast milk B12 depends on your stores. See do women need iron supplements.

What should you avoid or query?

• Herbal products marketed to boost milk supply: safety and effect are poorly documented. Ask a lactation consultant or pharmacist.
• Pre-workouts, fat burners and high-dose caffeine products.
• Anything with an unclear ingredient list, because unregistered complementary medicines carry a SAHPRA disclaimer saying they have not been evaluated.
• Large doses of single vitamins beyond the label.

Protein and collagen powders are foods, but they do not replace meals. Our multivitamin guide lists what is in common women's formulas.

When should you see a professional?

Speak to your doctor, clinic sister or a registered dietitian before starting supplements (especially if you are under 18, have kidney disease or take medication), and certainly if your baby has reflux, allergies or poor weight gain. This is general information, not personal medical advice.
