What is BOOST?
BOOST is a daily herbal supplement made for breastfeeding mothers. Each vegetarian capsule contains a standardized extract of milk thistle, a botanical traditionally used by nursing mothers. It is designed to support a healthy breast milk supply as part of your overall breastfeeding routine.
Many nursing mothers worry about supply at some point, especially in the early weeks or after returning to work. Frequent nursing or pumping, rest, fluids and good support make the biggest difference. BOOST is a simple herbal option some mothers choose to add, after talking it over with their doctor or lactation consultant.

What to expect
BOOST is meant to be one part of your breastfeeding routine. Every mother and baby is different, and results vary from person to person. Milk supply is driven mainly by how often milk is removed, along with rest, hydration and nutrition.
BOOST is not a substitute for lactation support or medical care. If you are concerned about your supply, or your baby has trouble feeding, seems unsatisfied after feeds, has fewer wet diapers or isn't gaining weight, contact your pediatrician or a lactation consultant right away.
