The best place to go for this is the Physician's Desk Reference listing for Immunocal. Here is what it states under the following categories:
"CONTRAINDICATIONS
IMMUNOCAL® is contraindicated in individuals who develop or have known hypersensitivity to specific milk proteins.
PRECAUTIONS
Each sachet of IMMUNOCAL® contains nine grams of protein. Patients on a protein-restricted diet need to take this into account when calculating their daily protein load. Although a bovine milk derivative, IMMUNOCAL® contains less than 1% lactose and therefore is generally well tolerated by lactose-intolerant individuals.
WARNINGS
Patients undergoing immunosuppressive therapy should discuss the use of this product with their health professional.
ADVERSE REACTIONS
Gastrointestinal bloating and cramps if not sufficiently rehydrated. Transient urticarial-like rash in rare individuals undergoing severe detoxification reaction. Rash abates when product intake stopped or reduced."
What this means is if you are allergic to milk protein or are on immunosuppressive drugs, you should discuss this with your doctor first. If you don't mix it up well, it could give you gas. And if you have a lot of stored toxins, you could develop a detoxification rash as the toxins are released until they exit your system.
Please compare this with the good effects of taking Immunocal:
"IMMUNOCAL® is a U.S. patented natural food protein concentrate in the FDA category of GRAS (generally recognized as safe) which assists the body in maintaining optimal concentrations of glutathione (GSH) by supplying the precursors required for intracellular glutathione synthesis. It is clinically proven to raise glutathione values.
"Glutathione has multiple functions:
1. It is the major endogenous antioxidant produced by the cells, participating directly in the neutralization of free radicals and reactive oxygen compounds, as well as maintaining exogenous antioxidants such as vitamins C and E in their reduced (active) forms.
2.Through direct conjugation, it detoxifies many xenobiotics (foreign compounds) and carcinogens, both organic and inorganic.
3.It is essential for the immune system to exert its full potential, e.g. (1) modulating antigen presentation to lymphocytes, thereby influencing cytokine production and type of response (cellular or humoral) that develops, (2) enhancing proliferation of lymphocytes thereby increasing magnitude of response, (3) enhancing killing activity of cytotoxic T cells and NK cells, and (4) regulating apoptosis, thereby maintaining control of the immune response.
4.It plays a fundamental role in numerous metabolic and biochemical reactions such as DNA synthesis and repair, protein synthesis, prostaglandin synthesis, amino acid transport and enzyme activation. Thus, every system in the body can be affected by the state of the glutathione system, especially the immune system, the nervous system, the gastrointestinal system and the lungs."
