Dr Hyman's new book recommends it with every meal! ..I'm proud if just remember to take it before dinner. Don't love it, but do 2T in water with stevia because it is "good for me" I recently bought the vinegar from Aldis, rich in color with the mother, looked more like Brag's than the Trader Joe house brand.
