Product Overview


  • Foundation for Longer Life
  • Naturally Vanilla Flavored
  • From Cows Not Tested with Growth Hormones (rBST)
  • Dietary Supplement

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.

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.

Suggested Use

Read the entire label and follow the directions carefully prior to use.

Mix one (1) scoop in approximately 4 to 8 ounces of water, milk or juice (to taste) daily, or as recommended by a healthcare practitioner. This product mixes best in room temperature liquid.

Other Ingredients

Provon 292 rBST free whey protein isolate, natural vanilla flavor, soy lecithin, maltodextrin, modified food starch, stevia extract.

Contains milk and soybean


This product contains whey protein isolate from cows not treated with growth hormone (rBST). The whey protein isolate is made using a process known as cross flow microfiltration, which produces an isolate that is 90% protein, 98% of it in the bioavailable undenatured form, and retains all important subfractions in their natural ratios.
