  • NOTHING FAKE: Levels Whey is naturally delicious. That means no hormones, no GMOs, no added sugars, no soy, no gluten, no bleach, no fillers, and no artificial flavors or sweeteners.
  • SIMPLE & CLEAN: No fake vanilla flavor here. Levels Vanilla Bean Whey is made with delicious Madagascar Vanilla Extract and lightly sweetened with monk fruit extract.
