Immunocal

My wife is been sick since childhood with chronic anemia and deficit iron absorption when her period comes was for more than 10 days with a lot of hemorrhage and drop her to the hospital to stopped now since she is been taking Immunocal her condition has been improve a lot and is in the Physician Desk Reference (PDR) is been scientific prove to work on u immune system by increasing u gluthatione

Methods of oral cystine delivery: Immunocal® is a specially prepared whey protein isolate which contains the thermolabile proteins serum albumin, alpha lactalbumin and lactoferrin. It is a patented form of bio-active, un-denatured whey protein isolate, and is described as a 'cystine delivery vehicle' and 'Glutathione precursor' by the Physicians' Desk Reference for Prescription Drugs (PDR 2001-2006). Serum albumin, alpha lactalbumin and lactoferrin proteins contain high levels of cystine residues that could be denatured by heat, low pH, or mechanical stress (inherent to most extraction processes). It is therefore recommended that high-speed mechanical blending or heating (above 118 degrees F) be avoided in the preparation of whey protein isolates such as Immunocal®. In serum albumin there are 17 cystine residues and 6 glutamylcystine (Glu-Cys) dipeptides; in lactoferrin, 17 cystine residues and 4 GluCys dipeptides; and in alpha-lactalbumin, 4 cystine residues. In particular, the Glu-Cys dipeptides very readily enter the cell to be synthesized into GSH. Of interest, the Glu-Cys dipeptide is an exclusive feature of the only obligatory foods in the early life of mammals and oviparous species, those being milk and egg white respectively. When subject to heat or shearing forces, the fragile disulfide bonds within these peptides are broken and the bioavailability of the glutathione precursors is greatly diminished. As an antioxidant, glutathione is essential for allowing lymphocytes to express their full potential, without being hampered by oxyradical accumulation during the oxygen requiring development of the immune response. In a similar fashion, GSH delays the muscular fatigue induced by oxyradicals during the aerobic phase of strenuous muscular contraction. As a detoxification agent, glutathione has been demonstrated to be effective against a number of xenobiotics, including chemical pollutants, various carcinogens and ultraviolet radiation.

Glutathione is a tightly regulated intracellular constituent and is limited in its production by negative feedback inhibition of its own synthesis through the enzyme gamma-glutamylcysteine synthetase, thus greatly minimizing any possibility of overdosage. [source: Physician's Desk Reference for Prescription Drugs (PDR) 2001, p. 1563].

Oral glutathione supplements as discussed previously, are virtually ineffective, since glutathione is a protein and is digested in the stomach before reaching the blood stream or tissues of the body.


N-acetyl-L-cysteine (NAC) is an amine protected version of cysteine that is rapidly hydrolyzed in the body to the amino acid cysteine. (Cysteine is the monomer amino acid).



NAC supplements are moderately effective, but dosing is limited due to toxic side effects (such as headache, dizziness, blurred vision) associated with cysteine supplementation.

Cystine is a disulfide linked dimer of cysteine, and a rich nutritional source of cystine in the diet is undenatured whey proteins. The link is a disulfide bond which is readily reduced to the corresponding thiol (-SH).


Scientifically, the best way to increase glutathione levels is to take a supplement rich in cystine (a disulfide-bonded form of cysteine). Immunocal® undenatured whey protein provides on of the richest sources of cystine known to science, and because cystine contains two weakly bonded molecules of cysteine, Immunocal® is a unique "cysteine delivery vehicle".
This form is virtually free of the toxic side effects associated with the single molecule (NAC). Two molecules of cysteine are connected by a weak disulfide bond to form a molecule of cystine. The disulfide-bonded cysteine is not digested, but is transported by the blood stream to the tissues of the body. Here, within the cells of the body, the weak disulfide bond between the two cysteine molecules is cleaved, and the cell has 2 molecules of cysteine from which glutathione can be manufactured. The greatest dietary source of cystine is bio-active, undenatured whey protein, and the only whey protein which has been studied in clinical trials at major Universities and Medical Schools and which is clinically proven to enhance or normalize glutathione levels is called "Immunocal". Immunocal is the only bioactive whey protein listed in the PDR Physicians Desk Reference for Prescription Drugs), even though it is available without a prescription.
A good, certified, and inexpensive blood glutathione test is available for about $40. Immunosciences testing laboratories.

What is Glutathione (GSH)?

Glutathione, or GSH, is a naturally occurring protein that protects every cell, tissue, and organ from toxic free radicals and disease. It is a tripeptide of three amino acids - glycine, glutamate (glutamic acid), and cysteine. These precursors are necessary for the manufacture of glutathione within the cells.
