We recommend consulting your healthcare practitioner before taking The Foundation if pregnant or breastfeeding. The active and versatile adaptogen, Ashwagandha, is included in our Adaptogenic B Complex formulation. While Ashwagandha is widely used in Ayurvedic medicine and we don't have reason to believe it's unsafe during pregnancy, it has not been explicitly tested for use during pregnancy or while breastfeeding. For this reason, we advise exercising caution and checking with your healthcare practitioner before using The Foundation. Additionally, The Foundation is not a prenatal vitamin, and combining The Foundation with additional supplements (like prenatal vitamins) is not advised.
