The dosage chart on the label is a recommendation by GNC Scientists for the best results from 100% Soy Isolate. It is recommended that the minimum daily dose is taken on each day based on activity level.

Pro Performance® 100% Soy Isolate is a protein shake that is cholesterol-free, with no lactose, and is from vegetarian sources. Soy protein is one of the most anabolic proteins. One of the biggest misconceptions behind this protein is the link to estrogen production; however, it contains all of the essential amino acids, including BCAA. BCAA may help preserve muscle glycogen stores and reduce the amount of protein breakdown during exercise. This formula features Supro® soy protein, one of the most clinically studied so proteins. Supro® is made from soybeans that are produced while being tightly monitored and controlled from planting through processing.

The Pro Performance® Results Advantage
Protein is an essential nutrient that is necessary for the growth, repair and maintenance of body tissues such as skin, bones and muscles. Studies have shown that soy protein taken by active individuals helps support muscles during exercise. Additionally, diets low in saturated fat and cholesterol that include 25g of soy protein a day my reduce the risk of heart disease.

One serving of Pro Performance® 100% Soy Isolate features 25g of protein providing an equivalent nitrogen factor of 25. Soy Protein is an effective source of nitrogen for fueling lean muscle mass. Your muscles can only grow when your body retains enough nitrogen. This formula delivers naturally-occurring anabolic amino acids into your bloodstream. This spike in aminos provides nitrogen and subsequently creates a nitrogen-rich environment needed for maximum muscle protein synthesis. Protein synthesis is crucial to the building of lean muscle mass.

The Pro Performance® Quality Advantage
GNC Pro Performance® 100% Soy Isolate is also tested for banned substances,* providing peace of mind in the highest quality formulation. Our researchers created a superior formula that not only delivers muscle fueling results, but every flavor has a satisfying, delicious taste profile. Each serving mixes up instantly with a blender, shaker, or a spoon- It’s that smooth and it couldn’t be easier.

Health Notes


  • Reliable and relatively consistent scientific data showing a substantial health benefit.
  • Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
  • For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.

Our proprietary "Star-Rating" system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.

For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.

    Comments about GNC Pro Performance® 100% Soy Isolate - Chocolate Supreme:

    I'm a vegan and a fitness junkie, so this product fits perfectly into my lifestyle. It really does help with recovery and it builds muscle. I also like to take it every day in the morning with my breakfast. I normally put a scoop or two of this powder in my blender cup, add COLD water (about 8 ounces), and just shake it. It's easy to take, but make sure you use cold water, this will not make it chalky. Don't be fooled by the name "SOY", this tastes AMAZING. This bag will last you a good two weeks.
