There are many important factors that contribute to milk supply, including rest, hydration, nutrition and frequent removal of milk from the breast via pumping or breastfeeding.
Adequate rest allows the body to recover and support optimal hormone production, which is essential for milk synthesis. Staying well-hydrated ensures proper milk volume and flow, while maintaining a balanced and nutritious diet provides the necessary energy and nutrients for milk production.
Furthermore, the Australian Breastfeeding Association states that there is an intrinsic relationship between the supply and demand of milk - the more milk that is removed from your breasts, the more milk your breasts will make.
Mama Goodness recommend that their products are used to provide additional support and not relied upon as the sole means of ensuring an adequate milk supply.
