Whey Protein and Immune Health

Biologically active whey protein has been formally recognized by the medical community for improving immune system function and detoxification. The Physician’s Desk Reference states that biologically active whey protein is an important contributor to health. It plays a major role in the following: Antioxidant production (Glutathione production via Cysteine and Glutamine supplementation) support against free radicals, maintains cell health, improved liver and lung function and support growth of new muscle.

Glutathione: A Powerful Antioxidant

Glutathione (GSH) is essential to immune system activity. It is the body’s primary antioxidant, detoxificant and anti-aging factor. Antioxidants are vitally important for the function of a healthy immune system, as they neutralize the free radical activity in the body.

Replenishment of Glutathione is one process for enhancing the body's immune response. According to the Journal of Immunology, "Lymphocytes, cells vital for your immune response, depend on GSH for their proper function and replication." (Immunology 61: 503-508, 1987).

Regarding whey protein concentrate, the journal Immunology 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 that lasts for a substantial post-ingestion time interval."

The Importance of Cysteine

Biologically active whey protein such as ImmunePro Rx, that contains naturally occurring Cysteine, is the optimal component for the intracellular production of Glutathione. Modern diets tend to be deficient in Cysteine, which causes limited Glutathione production. Supplementation with ImmunePro Rx replenishes Cysteine. It is important to note, heating destroys Cysteine, which is why ImmunePro Rx is subjected only to low-temperature, prolonged pasteurization. Most denatured whey protein products on the market are heated, which means that the Cysteine has been converted to a form which does not promote the production of Glutathione.

Recognized by the Medical Community

The Journal of the American College of Nutrition 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.

ImmunePro RX: Contains the Full Range of Undenatured Biologically Active Proteins

ImmunePro Rx contains the highest levels of Lactoferrin, Immunoglobulins, and Serum Albumin. These three protein fractions contain exceptional amounts of Cysteine and Glutamine, the precursors required for the production of intracellular Glutathione. ImmunePro Rx also naturally contains the full range of peptides and amino acids that support healthy tissue and proper immune function.

Here’s what people are saying about ImmunePro RX™:
"Although I have only been taking ImmunePro for about a month now, I can already state with confidence that it is the single greatest [whey]...I have tried... I am immensely pleased with my decision to use ImmunePro Rx." - Stephanie F., San Francisco, CA

"Undenatured whey proteins have been shown to raise levels of our body's powerful antioxidant and immune stimulant, Glutathione. However, these research findings further show that whey proteins have far more benefits than their ability to raise Glutathione." - Dr. J.P. Perraudin, Brussels, Belgium

"Glutathione is the body’s master antioxidant and best kept secret to maintaining health." - Theodore Hersh, M.D., Harvard graduate, Professor of Medicine, Emeritus, from Emory University.

What is the best way to store ImmunePro RX™?

60 degrees Fahrenheit (or cooler) in a dry location; refrigeration is acceptable.

What is the best solution to mix it in?

Purified water is the best liquid to thoroughly mix ImmuneProRx™. Use a sealable container to shake it, or a manual eggbeater. Do not use an electric blender. The whey proteins are easily denatured through heat and pH change. Mixing the whey protein with any other types of food can induce a pH change and slow the transit time in the stomach through its digestive response to the solid food. Liquids that are not neutral in their pH can also denature the proteins, for example: most fruit juices, coffee, and tea. By following the above guide, the uptake of the undenatured protein fractions in the upper small intestine is optimized. A small amount of Stevia is an acceptable sweetener, if desired, for palatability.

How much should I take and how often?

Servings can vary greatly for each individual. For many individuals it can be up to 5 grams, one, two, three, or more times per day. If you are unaccustomed to this whey protein concentrate, and there's a possibility you may be sensitive, we suggest that you begin with one measuring teaspoon (approx. 1.5 grams) or less per day, in the morning. Ingest on an empty stomach and do not eat for 30 minutes afterwards. Ramping up slowly is advisable to avoid possible uncomfortable responses. It is acceptable to alternate days of use for sensitive individuals. We recommend that you consult with your health care professional regarding dosage.

Possible Whey Protein Reactions:

Allergies to milk proteins and/or pasteurized dairy can make dairy consumption a problem. If you can drink raw or pasteurized milk, but cannot handle this whey protein, then the problem is probably elsewhere. True lactose intolerance presents itself as diarrhea, and is rarely a problem. Lactose content is 0.3g per 5 grams. For sensitive individuals, the use of a milk digestant that contains lactase and rennin can be helpful, as well as the concurrent use of probiotics. Ask your doctor about this issue.


If you are pregnant or have an existing health condition, please consult with your health care professional before using this product. If you are unaccustomed to this whey protein concentrate, and there's a possibility you may be sensitive, we suggest that you begin with one measuring teaspoon (approx. 1.5 grams) or less per day, in the morning. Ingest on an empty stomach and do not eat for 20 minutes afterwards. Ramping up slowly is advisable to avoid possible uncomfortable responses. If you experience bloating from drinking the solution, try placing 1 teaspoon at a time of the whey powder in the mouth, and let it dissolve by slowly chewing it. For sensitive individuals, it is acceptable to alternate days of use.

Nice taste, a little lumpy if you don't stir it enough or blend it. I feel healthy after drinking it.
