If wanting only cocoa powder, a much better choice was Ghirardelli Chocolate Premium Baking Cocoa — 100% Cocoa. It had 44 mg of flavanols and 0.6 mcg of cadmium per tablespoon.
Also, Volupta Cacao Powder was a “good” choice (never heard of this one before). A tablespoon had 55 mg of flavanols and 2.9 mcg of cadmium (borderline of high).
Thanks but this and others are too expensive.
