A note or two about selenium
Selenomethionine, though the most popular form of selenium found in supplements, is most commonly produced from selenide in sulfide ores such as those of copper, silver, or lead. It is obtained as a byproduct of the processing of these ores, from the anode mud of copper refineries and the mud from the lead chambers of sulfuric acid plants. These muds can be processed by a number of means to obtain free selenium.
When it comes to fighting cancer, recent anticancer research has focused on the compound Methyselenocysteine. Methyselenocysteine is found naturally in some vegetables including garlic, brassicas, leeks, and onions, especially when these are grown in high selenium soil. Methylselenocysteine is easily converted to methylselenol which has been demonstrated to be an effective anticancer form of selenium. Rather than killing cancer cells by necrosis, methylselenol kills cancer cells through apoptosis. Apoptosis is a orderly process of cellular self-destruction that does not provoke inflammatory responses. Methylselenol is also known to inhibit angiogenesis in beginning cancer tumors. Angiogenesis, the creation of new blood vessels, is necessary for cancer cells to grow into a tumor.
