An Overview of Milk Thistle and Breastfeeding
is an herbal supplement often recommended for increasing breast milk supply. However, no reliable scientific studies have demonstrated that it is safe (or even if it really works to increase milk supply).
Is Milk Thistle Safe While Breastfeeding?
It is not known if milk thistle supplements are safe (or unsafe) for women who are breastfeeding. No studies have evaluated the safety of milk thistle for use during breastfeeding. Similarly, no studies have evaluated the effectiveness of milk thistle for increasing breast milk supply in humans.
Although this herbal supplement has been traditionally used as a galactalogue (a substance to stimulate breast milk production), theoretically, milk thistle might actually have a negative effect on the quantity and quality of breast milk. Milk thistle may have estrogenic (estrogen-like) properties, which might interfere with the normal production of breast milk.
