Fenugreek is one of the most effective herbs for increasing breastmilk production. It has been successful in even the most difficult of cases. Fenugreek must be used with consistency to experience best results. Using it as a single-herb product such as this (meaning it is the only herb contained in the product), is highly effective and is extremely easy to use and regulate. Using it as a single herb product provides best results.  Note: Fenugreek is not recommended for use during pregnancy as it has some slight uterine stimulating properties.
