Whey Protein

The Importance of Cysteine vs. Cystine Biologically active whey protein that contains naturally occurring Cysteine is the optimal component for the intracellular production of Glutathione (GSH). Cysteine is very scarce in our modern diet and therefore Glutathione production is limited and deficiency is prevalent. If Cysteine undergoes any heating or processing, as all conventional dairy and dairy by-products do, it is denatured and converted to Cystine. Cystine is the form that is found in all of the medical food whey proteins, as they are all by-products. ImmunoPro Rx whey protein powder is unique as it is a Primary-Product and contains naturally occurring Cysteine. An important note on the synthesized free form amino acid L-Cysteine, it can have adverse effects in supplemental doses with sensitive individuals or those who have any heavy metal accumulation.

The Journal of the American College of Nutrition Volume 5, 1986, published a paper by Anderson and Meister titled ''Intracellular Delivery of Cysteine and Glutathione Delivery Systems.'' It concluded that when subjects were fed naturally occurring Cysteine, it gave them significantly more production of Glutathione than when fed Cystine. Eleven times more.

Whey Protein Powder

Regarding Whey Protein Concentrate: The journal Immunology 61: 503-508, 1987 reports, The bioactivity occurs through the ability of the protein concentrate to help replenish Glutathione levels via continuous dietary provision of Glutathione precursors, especially Cysteine, during lymphocyte proliferation, thus supporting an optimal immune response. This process seems to not only increase intercellular levels of Glutathione and precursors at the time of ingestion, but also builds up stores of these substances within the cells which lasts for a substantial post-ingestion time interval.

ImmunoPro Rx whey protein powder is the only True Nondenatured Biologically Active Whey Protein. It is a Primary-Product and contains the full range of naturally occurring protein fractions. It contains the highest levels of Lactoferrin, Immunoglobulins, and Serum Albumin. Laboratory verified* as many times higher than the leading whey protein products. These three protein fractions contain exceptional amounts of Cysteine and Glutamine, the precursors required for the production of intracellular Glutathione.

ImmunoPro Rx whey protein powder contains the following protein fractions.

• Lactoferrin, an iron-binding, iron-modulating protein that enhances iron absorption when needed, also anti-viral, anti-bacterial and anti-inflammatory properties. 340 milligrams* per 10 grams.
• Immunoglobulins, with numerous immune system benefits. 1.6 grams* per 10 grams.
• Bovine Serum Albumin, along with Lactoferrin and IgGs contain generous amounts of Cysteine and Glutamine, precursors in Glutathione (GSH) production.
• Active Peptides (specialized paired amino acids), exhibit a beneficial information transfer factor effect on the immune system as well as boosting intracellular Glutathione.
• Growth Factors (growth promoting protein fractions) are contained within the protein bound fats. Their function is to: Regenerate all aged or injured cells in the body. Build and retain muscle. Burn fat for fuel. Repair DNA and RNA. Fight infections. Help regulate blood sugar and brain chemicals.

* ImmunoPro Rx™ whey protein powder is far more potent than any whey protein product available.
