Levels Grass Fed Whey Protein Powder, No Artificials, 24G of Protein, Vanilla Bean, 2LB

Why we love it

High-quality protein source.
No artificial ingredients.
Delicious and clean flavor.

Main Highlights

LEVELS WHEY PROTEIN: Each scoop of Levels Vanilla Bean Whey contains 24g Protein, 5.4g BCAAs (branched-chain amino acids), and no added sugars. Trusted by athletes, fitness enthusiasts and daily grinders everywhere, our whey is crafted for everyone’s lifestyle.
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.
QUALITY FIRST: Quality milk tastes better, way better. That’s why grass-fed hormone-free dairy is the only dairy we use to make our whey protein concentrate. Whey concentrate is the least processed form of whey, which means it’s loaded with high-quality complete protein and essential amino acids.
MADE IN THE USA: Levels Whey Protein is made in the U.S.A. and is undenatured to protect bioactivity and naturally occurring growth factors. Each batch is cold-process microfiltered and blended with non-gmo sunflower lecithin for that insanely easy mixing you expect.
