Yes, I meant cacao powder, hopefully raw, in that state it is also high in vitamins. It is high in many minerals. I buy Chinese organic algae powder from Starwest botanicals. No problem for anyone whom I had recommeneded it to, so far (at least 10-15 people). Cholorella needs to by with broken cell walls.
I have a box of wheatgrass powder myself, and I am hesitant to open it, since I now it also has gluten it, even though in small quantities. On the positive side it has vit B17. For now I get by with all of the above plus sprouts.
