Protein powder can be safe for breastfeeding mothers to consume, but it is important to choose a high-quality product that is free from contaminants and artificial ingredients, and to consult with a doctor or a registered dietitian before starting any new supplement.
Breastfeeding mothers have increased nutritional needs, and protein is an essential nutrient for both the mother and the baby. Consuming an adequate amount of protein can help support milk production and also aid in the recovery and repair of muscle tissue after childbirth.
However, some protein powders may contain ingredients or contaminants that are not safe for breastfeeding mothers or their babies, so it's important to choose a product that is specifically formulated for breastfeeding mothers or to consult with a doctor or a registered dietitian before starting any new supplement.
We do advise however not to use soy-based protein powders while breastfeeding. Soy protein contains isoflavones that mimic the hormone estrogen. This is an important hormone and some experts warn that consuming too much may negatively affect your baby’s development.
In general, it is recommended that breastfeeding mothers aim to consume an adequate amount of high-quality protein from a variety of sources, including foods such as lean meats, dairy products, eggs, beans, and legumes, as well as potentially a high-quality protein powder if needed.
