Whey Protein Isolate: A Pure, NSF Certified Fuel for Muscle Recovery

Thorne’s Whey Protein Isolate delivers a high-quality, easily digestible protein source designed to support the ambitious goals of athletes and fitness enthusiasts. Sourced from cows in the USA, this premium protein powder is formulated for optimal absorption, providing the essential building blocks your muscles need to repair, rebuild, and grow stronger. With a delicious vanilla flavor, minimal sugar, and no artificial sweeteners, it’s the clean, effective way to enhance your training recovery and support the development of lean muscle mass. As it’s NSF Certified for Sport®, you can be confident it’s free from banned substances.*

How It Works: The Power of Pure Protein and BCAAs

Whey protein isolate is one of the most bioavailable forms of protein, meaning your body can utilize it quickly and efficiently, making it ideal for post-workout consumption.*

Optimized for Lean Muscle and Recovery
With 21 grams of protein per serving and a low count of sugar, calories, and fat, this formula is engineered to support lean body mass. The isolate form undergoes a microfiltration process that separates the pure protein from most of the lactose and fat, resulting in a product that’s easy to digest. It is naturally rich in branched-chain amino acids (BCAAs)—leucine, isoleucine, and valine. Leucine, in particular, is a key amino acid that signals the body to initiate muscle protein synthesis, the process responsible for muscle repair and growth.*

Enhanced with Digestive Enzymes
To further promote digestive comfort and nutrient absorption, Thorne’s Whey Protein Isolate is enhanced with a proprietary blend of digestive enzymes, including bromelain and papain. These enzymes help the body break down the protein into smaller, usable peptides and amino acids, ensuring you get the maximum nutritional benefit from every serving while minimizing the potential for bloating.*

  • Promotes muscle repair and the growth of lean muscle mass*
