Abstract

Mercury is ubiquitous in the environment, and in our mouths in the form of "silver" amalgams. Once introduced to the body through food or vapor, mercury is rapidly absorbed and accumulates in several tissues, leading to increased oxidative damage, mitochondrial dysfunction, and cell death. Mercury primarily affects neurological tissue, resulting in numerous neurological symptoms, and also affects the kidneys and the immune system. It causes increased production of free radicals and decreases the availability of antioxidants. It also has devastating effects on the glutathione content of the body, giving rise to the possibility of increased retention of other environmental toxins. Fortunately, effective tests are available to help distinguish those individuals who are excessively burdened with mercury, and to monitor them during treatment. Therapies for assisting the reduction of a mercury load include the use of 2,3-dimercaptosuccinic acid (DMSA) and 2,3-dimercato-1-propanesulfonic acid (DMPS). Additional supplementation to assist in the removal of mercury and to reduce its adverse effects is discussed.
