More Oxygen Hype:
"Magnesium-Based Oxygen Therapy"

Stephen Barrett, M.D.

"OxCgen Advanced Activated Oxygen for Colonic Cleansing & Health" is said to contain 500 mg of magnesium oxide, 75 mg of vitamin C, 25 mg of bioflavonoids packaged in a vegetable-based capsule. It claimed to "release activated oxygen—a unique and powerful mixture of oxygen and ozone - initially into the digestive tract." According to a site that promotes it:

This powerful cleansing 'activated oxygen' can give the entire tract the kind of clean it has been wanting for years.

After cleansing and releasing, the impacted matter and dead fungal components are then gently released by the magnesium in the capsules. After oxygenating the colon, the gases released by the reaction of these capsules with the digestive acids are then absorbed and distributed throughout the body.

It is widely believed that a clean colon is pivotal for optimal health. These capsules have proven themselves to have the ability to clean out impacted matter from the colon and thus revitalize the entire digestive and assimilation process.

Besides regular and easy bowel movements OxCgen can also help reduce weight. Digestion is basically a process of burning food and insufficient oxygen in the colon leads to incomplete burning/digesting of food which is then often stored as fat for later digestion. You thus still feel hungry and eat some more. Which again ends up being stored as fat and the cycle continues. It is not uncommon for substantial weight loss to occur within a few weeks of initiating a program of OxCgen cleansing.

As well as having a regular clean bowel and weight loss OxCgen, as oxygen is used by the brain you will also be thinking more clearly as well.

Other so-called "magnesium-based oxygen therapy products" are marketed with similar claims. Colosan, Homozon (sometimes spelled Homozone), and Oxy-Powder contain no vitamin C. They are claimed to work by "oxidizing toxins and fecal matter in the bowel and not by irritating it as with conventional laxatives."

I do not believe these claims are valid. They are based on outmoded concepts that intestinal contents stick to the the intestinal walls, interfere with passage of the stool, and need to be cleaned off to make people healthy. No such process occurs [1,2]. Doctors who examine the intestinal tract with medical instruments see no evidence of such a process. Moreover:
