“I was on this supplement while pregnant and waited until 4 weeks post partum to start taking it again. By 5 weeks PP I had almost no supply (have exclusively breastfed 2 prior children to 1 year with no supply issues). Thank goodness I checked the ingredients; chickweed is in this supplement which reduces milk supply. I stopped taking it and with no other changes my supply returned 3-4 days later. My daughter is 12 weeks now and thankfully growing. Don’t take when nursing!!!”
