The Most Complete Plant-Based Fromula
GNC Pro Performance® 100% Soy Isolate is a cholesterol-free, lactose-free and gluten-free formula. This vegetarian soy isolate contains all 9 essential amino acids, which your body requires daily for optimal muscle function and performance. This unique soy formula supports your muscles during exercise and fuels lean muscle mass during your post-workout recovery.

The Pro Performance Results
Protein is an essential nutrient that is necessary for the growth, repair and maintenance of muscle fibers. Studies have shown that soy protein taken by active individuals assists in maintaining muscle health during exercise. Additionally, diets low in saturated fat and cholesterol may reduce the risk of heart disease. GNC Pro Performance® 100% Soy Isolate provides 20g of soy protein and is a cholesterol-free formula. Soy Protein is an effective source of nitrogen, which fuels lean muscle mass. Your muscles can only grow when your body retains a sufficient amount of nitrogen. This unique formula delivers naturally-occurring anabolic amino acids into your bloodstream. These aminos create a nitrogen-rich environment required for maximum protein synthesis.

The Pro Performance Quality
GNC Pro Performance® 100% Soy Isolate has been tested for over 145 banned substances. This formula has been confirmed as banned substance free, providing a complete peace of mind that you are receiving the highest quality formulation. This superior formula delivers muscle-fueling results while maintaining a satisfying and delicious taste.

Great but when will it be back in stock?!
I have used this for years nd love it but it hasn't been available for months. Please tell us this hasn't been discontinued. When will it be back in stick? Due to food allergies other forms of protein don't work for me.

I really enjoy this protein powder. I mix it with a little water in a container and it turns into a frosting type substance and it taste great!

100% Soy Isolate
My wife and I have used ISP for years. I started using based on research of benefits (*gastro, heart, low carb, etc.) done by the company I worked for (Protein Technologies, Solae, now DuPont Nutrition). Until I retired, I was able to purchase the Supro brand through the company as it is a premium soy isolate. Since retiring, I have tried several brands and used the GNC brand when I could identiy the Supro trademark. I am now using this product based on the price, nutritional information, and taste.

I read that soy is helpful for prostrate and I have a family history of prostrate cancer. I mix it with milk and frozen strawberries.

Why I love Soy Isolate
I love the Vanilla Soy Isolate because it mixes with frozen fruit in a blender with a bit of vanilla yogurt and a banana and you have a full meal for a great start for breakfast. Jump starting the body to loosing weight each day.
