What is Soy Protein Isolate Powder?
Soy Protein Isolate is a concentrated source of high-quality soy protein. Soy Protein Isolate supplies the necessary amino acids, including the essential amino acids, to help support muscle growth. Soy Protein Isolate provides Glutamine and Arginine, two amino acids associated with hormone release and immune function. Soy Protein Isolate also contains naturally-occurring antioxidants. A common misconception with Soy Protein, in general, is that it limits testosterone in men; however, contrary to belief, there is no viable research that supports this claim. An in-depth review study showed that neither soy foods nor soy isoflavone supplements alter testosterone measurements in men. [1]

Potential Benefits of 100% Soy Isolate Protein Include:

  • May Support Weight Loss †
  • Supports Healthy Cholesterol †
  • Supports Lean Muscle Mass†

How Does Soy Protein Isolate Powder Work?
Made from defatted soybean flakes that have undergone an alcohol wash, soy protein operates similarly to whey protein. Soy protein, however, boasts fewer calories. Due to this reduction in caloric intake, it becomes a viable solution for those seeking to lose weight while still getting their intake of protein. In some studies, soy protein has been shown to boost weight loss just as effectively as animal-based proteins.
Soy protein is known as a complete protein, meaning that it contains all of the essential amino acids that your body requires from food.

    Bought the 7 lb option. It came in a very nice bucket with a hinged lid, the powder is double wrapped in a plastic bag. It tastes good. Came with a scoop in the powder. No complaints. Will order again in the future.
