In "The Nursing Mothers Herbal," Cheryl Renfree, a lactation consultant in California recommends adding brewer's yeast to your diet for B vitamins, iron and protein. Many mothers have found brewer's yeast to be helpful not only for building their milk supply, but also for combating fatigue, depression and irritability. You can Google "lactation cookies" and the recipes will have several ingredients including brewer's yeast in them that support breastfeeding. I hope this helps!

To increase your milk supply, from a nutritional standpoint, make sure you're staying hydrated and eating an overall well-balanced diet full of fruits and vegetables. Also consider increasing oatmeal (steel cut or old fashioned) and whole grains as they have been shown to increase milk production, although the mechanism is not fully understood. Maintain a consistent intake of carbohydrates as diets that are low in carbohydrates can significantly reduce milk production.

There are prescription, herbal and nutritional substances that have been shown to increase milk production, however, it is important to fully address the underlying cause of low milk production. My advice is to work directly with a medical professional that is familiar with the effectiveness and safety of the supplements/herbs you are considering as there may be unintended side effects or interactions with other medications you may be taking.
