Life Extension Whey Protein Isolate is a proprietary 98% undenatured whey protein isolate that utilizes a cross flow microfiltration technique. It supports the immune system, muscle function & growth, cardiovascular function and is a powerful antioxidant.

Scientists have known for years that certain biological components of whey protein (including lactoferrin, beta-lactoglobulin, alpha-lactalbumin, glycomacropeptide, and immunoglobulins) have a beneficial impact on the immune system. Life Extension offers a specially designed whey protein isolate, using proprietary production methodology, that has been shown to support healthy immune function, protect against free radical attack, and help maintain lean muscle mass.1-5 Using a cross flow microfiltration technique, it is possible to produce a high-quality, 98% undenatured whey protein isolate that acts as an immune stimulant and retains all the important subfractions, such as lactoferrin, a strong antioxidant with immune-stimulating properties.6-7

Whey protein:

  • contains a high concentration of branched-chain amino acids (BCAAs) leucine, isoleucine and valine, which play an important role in maintaining healthy muscle function
  • is rich in sulfur-containing amino acids cysteine and methionine, which support a healthy immune response through intracellular conversion to glutathione
  • provides potent antioxidant activity
  • supports healthy cardiovascular function by maintaining healthy blood pressure and lipid levels that are already within a normal range
  • promotes protein synthesis and muscle growth
