Is Greens from "it works" safe while nursing?

Jessica • Married 7 years, 1 baby. I have polycystic ovaries. It is possible! And we have 3 doggies whom we love to pieces
Has anyone gotten this approved by their doctor? My dr is on vacation and I'm anxious. I've been taking this for a week and it seems like my 9 week olds tummy issues are getting better. Label says check with a physician like everything does these days. Ingredients look normal nothing weird. But now I'm scared hubby heard they are bad while breastfeeding.
