Professor Maret Traber from the Linus Pauling Institute in the United States has studied vitamin E for a number of years. Traber, in a review article, looked at the most recent science concerning this important, lipid-soluble nutrient. Judging from her work, it looks as if we only need the form of vitamin E called alfa-tocopherol.
Ever since the discovery of coenzyme Q10 in 1957, scientists have been conducting research with this intriguing nutrient that appears to play a crucial role in human health. Another word for coenzyme Q10 is “ubiquinone” because of its omnipotent importance. “Ubi” means everywhere. In 2006, a new type of CoQ10 called “ubiquinol” surfaced commercially. Clever marketing campaigns attempted to pawn this off as the new and improved CoQ10 source that was absorbed more easily in the body and was superior to ubiquinone. Consumers as well as scientists got confused and started questioning the traditional form of CoQ10 – ubiquinone – although it had been sold commercially and used in studies all along.
Chromium is an element and a metal. To humans, it is also an essential micronutrient in the form of so-called trivalent chromium. Chromium also exists as divalent and hexavalent chromium but these forms are toxic. All approved chromium supplements contain trivalent chromium. The various chromium forms can bind with a variety of chemical compounds to form other substances.
Years of scaremongering against fat has had the unfortunate consequence that many women get too few essential fats in their diet, such as the omega 3 fatty acids EPA and DHA. Since we humans are unable to produce them in the body, we rely on a steady supply from our diet. This makes them just as important as vitamins and minerals.
Osteoarthritis makes life difficult for many people but with glucosamine both the symptoms (pain and tenderness) and the breakdown of joint cartilage is effectively halted. The better our joints work, the easier it is to stay physically active and enjoy all the activities that help to keep us youthful and in good shape.
Selenium is a mineral that is related to sulfur. Plants take up selenium from the soil in the form of selenate, just like they take up sulfur as sulfate. The body contains around 13-20 mg of selenium, of which 50% is stored in the liver. All cells contains selenium. The highest selenium concentrations are found in the sexual glands and in semen.
Essential nutrients are those vitamins, minerals, fatty acids and amino acids that the body needs in order to function. We can't do without these substances and there are no other substances that can replace them. It is possible to live a full, long life without ingesting for example, ginseng, rose hips extract and medicine, but it is not possible to survive without getting all the essential nutrients. Deficiency of these substances will inevitably lead to nutritional deficiencies.
