After decades of research, the only supplement or agent with demonstrated radioprotective effect is potassium iodide. However, this treatment is quite limited, protecting only one organ – the thyroid gland – and only against one radioactive substance: radioactive iodine. Furthermore, government supplies are rapidly depleted when major events such as the Fukushima nuclear accident occur. In contrast, the BioShield formulation may impact multiple forms of radiation and the damaging free radicals produced by radiation and other environmental hazards and occupations in a variety of circumstances.
