Vitamin D might be effective against radiation

The wonders of vitamin D as a health supplement have already been recognized by numerous studies, with many experts pointing out that most people take in too little of the so-called "sunshine vitamin."

Now, another novel use for vitamin D has been uncovered. A health expert suggests that a form of vitamin D may protect the body from radiation, which could be used to shield people from a low-level nuclear incident.

Daniel Hayes, Ph.D., of the New York City Department of Health and Mental Hygiene says in the International Journal of Low Radiation that calcitrol, a form of vitamin D, might be useful as an effective agent to protect people against an accidental nuclear incident or terrorist attack.

Hayes believes that calcitrol, the biologically active form of Vitamin D, could be used to prevent cancer caused by radiation.

"Our general understanding and appreciation of the multifaceted protective actions of vitamin D have recently entered a new era," writes Hayes.

Currently potassium iodide (KI) is used following a radiological or nuclear event. According to the Centers for Disease Control and Prevention, KI may cause thyroid problems.
