Breastfeeding moms. What supplements are you taking besides your prenatal?

prenatals lactation cookies and fenugreek

I've just started taking Vit D. Apparently most babies are not getting enough and there is not enough in the prenatals. Ive been reading up on it. Now I'm wondering if there's any other I should be taking. I take fish oils as well

Brewers yeast, fenugreek, mothers milk, and lactation cookies

Mothers milk
