Free radicals are intermediates in many normal and necessary metabolic reactions. Thus, all oxygen-using organisms have had to evolve defensive mechanisms against free radicals: The enzymes catalase and peroxidase break down hydrogen peroxide and other peroxides, superoxide dismutase (called SOD) controls the superoxide free radical, and glutathione peroxidase also controls peroxides. Antioxidants such as vitamins […]

One of the most important factors leading to immune system decline is the greatly reduced rate of release of growth hormone by the brain as we age. This hormone, produced by the pituitary gland, begins to fall off in quantity after your teens. Since the thymus gland requires growth hormone to function properly, this decrease […]
