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 developed a specially designed whey protein, 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 low temperature microfiltration technique, it is possible to produce a high-quality, 98% undenatured whey protein isolate that acts as a powerful immune stimulant and retains all the important sub-fractions, such as lactoferrin, a strong antioxidant with immune-stimulating properties.

This product contains whey protein isolate from cows not treated with growth hormone (rBST0). 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.
