Tailwind Recovery Mix contains rice protein and some flavors contain coffee beans and/or cocoa powder. These ingredients may contain naturally occurring lead at levels well under health agency thresholds including the FDA, EU and Canada. Cadmium can also enter cocoa beans during growing and production phases from environmental sources like forest fires, volcanic activity and rock weathering. Our supplier uses a blending method to keep cadmium at the lowest possible range. We request the test results for each batch we order to confirm levels are in the allowable range.
