Ionizing radiation such as cosmic radiation or X-rays from medical diagnostic imaging procedures can cause harm to human body tissues by mechanisms including direct DNA damage and the production of toxic free radicals. In addition to limiting and/or avoiding excessive ionizing radiation exposure from various sources (e.g. frequent medical diagnostic imaging procedures like CT and/or PET scans, recurrent transcontinental plane travel) whenever reasonable, additional cellular support during radiation exposure and subsequent free radical generation is helpful for optimal health.Research indicates that certain nutrients may help support the body’s cellular integrity in the context of ionizing radiation.The new X-R Shield provides the following protective nutrients:Lemon balm supports the production of 3 bodily enzymes that form a natural defense system against free radical and DNA damage: superoxide dismutase, glutathione peroxidase, and catalase.Ginkgo biloba supports the body’s capacity to counteract reactive oxygen species, which can interact with DNA. Spirulina supports the production of white blood cells in the bone marrow. These immune cells are essential for a healthy immune response.
