What are the Pros and Cons of Using Immunocal?

Immunocal is a natural dietary protein concentrate that helps the body maintain appropriate glutathione (GSH) concentrations by giving the precursors needed for intracellular glutathione production. It has been clinically demonstrated to increase glutathione levels.

Immunocal supplement is protected by multiple patents in the United States and around the world, and it is classified as GRAS (generally recognized as safe) by the FDA. It helps the body maintain appropriate glutathione (GSH) concentrations by delivering the precursors needed for intracellular glutathione production. It has been clinically demonstrated to increase glutathione levels.

Glutathione is a tripeptide that is synthesized intracellularly from the amino acids L-glutamate, L-cysteine, and glycine. The sulfhydryl (thiol) group (SH) of cysteine is responsible for glutathione’s biological function. Because accessible cysteine is scarce in foodstuffs, the availability of this amino acid is the rate-limiting element in cell glutathione synthesis.

Immunocal is a bovine whey protein isolate that has been carefully produced to give a high concentration of accessible cysteine. As a result, Immunocal® can be seen as a cysteine delivery method.

The disulphide bond in cystine is resistant to pepsin and trypsin, but it can be broken by heat, low pH, or mechanical stress, releasing free cysteine. Heat or shearing pressures (inherent in most extraction procedures) break the weak disulfide bonds within the peptides, reducing cysteine bioavailability significantly.

Glutathione is a tightly regulated intracellular ingredient whose production is limited by negative feedback regulation of its own synthesis via the enzyme gamma-glutamylcysteine synthetase, reducing the likelihood of overdosage significantly.

What are the common ingredients in immunocal?

Immunocal is a dietary supplement that mainly contains cysteine-rich whey protein isolate, which helps boost the body’s natural antioxidant, glutathione. Glutathione plays a crucial role in various bodily functions, including supporting the immune, nervous, gastrointestinal, and respiratory systems.


Immunocal supplement contains glutathione, a powerful compound with multiple functions that contribute to overall health:

  1. Glutathione acts as a vital endogenous antioxidant, protecting cells by neutralizing harmful free radicals and reactive oxygen compounds. Additionally, it helps maintain other antioxidants like vitamins C and E in their active forms.
  2. It plays a crucial role in detoxifying various foreign compounds and carcinogens, both organic and inorganic, through direct conjugation.
  3. Glutathione is essential for the optimal functioning of the immune system. It influences cytokine production, antigen presentation to lymphocytes, and the type of immune response (cellular or humoral) that develops. It also enhances lymphocyte proliferation and boosts the killing activity of cytotoxic T cells and NK cells, while regulating apoptosis to maintain immune response control.
  4. Glutathione is involved in a wide range of metabolic and biochemical reactions, such as DNA synthesis and repair, protein synthesis, prostaglandin synthesis, amino acid transport, and enzyme activation. As a result, the state of the glutathione system can impact various systems in the body, including the immune system, nervous system, gastrointestinal system, and lungs.

Is immunocal good enough for cancer?

Immunocal holds a method-of-use patent for cancer prevention and treatment. Some malignancies’ side effects can be reduced by using it. Immunocal is the only natural substance that has been patented for safely increasing and maintaining GSH levels.


Immunocal provides nine grams of protein each sachet. Patients on a protein-restricted diet must account for this when determining their daily protein load. Immunocal, although being a bovine milk product, contains less than 1% lactose and is thus well tolerated by lactose-intolerant people.

Patients taking immunosuppressive therapy, on the other hand, should consult with their doctor before using this product. Furthermore, if you are dehydrated, you may experience gastrointestinal bloating and cramps while using Immunocal. Transient urticarial-like rash can develop in rare individuals enduring severe detoxification reactions, but the rash resolves when the substance is stopped or lowered.
