Whey Protein Isolate is ideal for people who need additional protein in their diets – from world-class athletes to individuals managing their weight.* It is low in sugar, calories, and fat. NSF Certified for Sport®
What is it: a convenient and versatile source of high-quality protein. Whey is a fast digesting protein with a high amino acid content, specifically leucine, the amino acid necessary to start protein recovery and growth.* One serving of Thorne’s Whey Protein Isolate contains the amount of leucine necessary to trigger the recovery process.* We’ve chosen whey protein isolate as our protein source because of its excellent absorbability and digestibility.
To further improve digestibility, we add digestive enzymes derived from papaya and pineapple to minimize the gastric discomfort that some individuals experience with protein powders.
Who it’s best for: Whey Protein Isolate is best for individuals who are seeking a quick, fast-digesting protein source. Because of its high leucine content, whey protein isolate is popular among athletes and active individuals. To support our professional athletes and athletes subject to drug tests, we submit our Whey Protein Isolate to a third-party organization, NSF International, to confirm our protein sources are free of more than 200 substances banned for athletic competition.
