Maintain Muscle Mass and More with Protein

Protein supplements are backed by years of clinical research for muscle health, immune system health, longevity and more. Protein is a major macronutrient our bodies need, influencing our muscle mass and many other body systems, including immune response and gut integrity. Our supplements provide non-GMO sources of protein with other nutrients, such as branched chain amino acids that complement their health benefits.

Protein Concentrate

Wellness Code® Whey Protein Concentrate comes in delicious, vanilla- and chocolate-flavored, powdered protein shake mixes that deliver 20 grams of protein with no added sugar and plenty of branched-chain amino acids (BCCAs) in every scoop.

See Protein Concentrate Products

Our family of protein isolate supplements offer the benefits of whey protein, but with lower carbohydrates, lactose and fat than the concentrate form. That is because we use a process called cross-flow microfiltration, which produces an isolate that is 90 percent protein and retains all important subfractions in their natural ratios.
