[Dr Mercola] If you're looking for strategies to help prevent damage caused by radioactive fallout from the recent nuclear disaster in Japan, researchers noted in the International Journal of Low Radiation that the most active molecular form of vitamin D -- D3 (also known as calcitriol) -- may offer protection against a variety of radiation-induced damages, including those caused by background radiation or a low-level nuclear incident, through the following mechanisms:
· Cell cycle regulation and proliferation
· Cellular differentiation and communication
· Programmed Cell Death (PCD)
· Anti-angiogenesis (a process that stops tumors from making new blood vessels, which means they stop growing)
The protective mechanisms are so strong that researchers suggested vitamin D3 should be considered among the prime (if not the primary) non-pharmacological agents to protect against sub-lethal low radiation damage and, particularly, radiation-induced cancer.
Researchers have found that daily intakes of vitamin D by adults in the range of 4,000-8,000 IU so your blood levels are in therapeutic range are needed to maintain blood levels of vitamin D metabolites in the range needed to reduce the risk of breast and colon cancers by about half. You can find out more about how to use vitamin D therapeutically to reduce radiation damage here.
