In the late 1970s, Dr. Gustavo Buonous and his colleagues at McGill University began their research to create an immune system-boosting protein supplement. They eventually discovered a milk serum that could keep human glutathione levels healthy. Glutathione is a protein that occurs naturally in the body, and sick people often have unhealthy levels of it.

Keep glutathione levels healthy, and the immune system improves. Dr. Buonous and his colleagues named their milk-derived protein isolate Immunocal. Immunocal raises glutathione levels by delivering cysteine to the body. Glutathione thrives on cysteine, an amino acid that our diets often lack. Immunocal is distinguished and protected by a remarkable seven patents in North America, as well as many international patents.

Immunocal and the Medical Community

Although Immunocal is an over-the-counter supplement, it is listed in the United States Physicians' Desk Reference as well as the Pharmacists' Red Book. This is a rare distinction, indeed. It is also one of the few nutritional products that qualifies for reimbursement from insurance companies. Immunocal is very highly respected in the medical community.

More importantly, it's a blessing for those who take it. Many people who use Immunocal are chronically ill. Among those who should strongly consider taking Immunocal are people with cancer, HIV, chronic fatigue syndrome, Alzheimer's disease, multiple sclerosis, Parkinson's and lupus. If you have a chronic disease, talk to your doctor about Immunocal and what it can do for you.

If you read the page on carbohydrate metabolism, you might recall that your body stores complex carbohydrates (from wheat, barley and vegetables) in the form of glycogen in liver and muscle cells. When your body increases its demand for these carbs, like if you were to go for a jog or hit the gym, these stored carbs are broken down into smaller, usable units called glucose 6-phosphate (this is just glucose when a phosphate group attached).
