Vitamin C may help high blood pressure

In an Italian study in the Journal of Clinical Nutrition, researchers treated 12 patients with high doses of vitamin C given intravenously.

On average, after about 20 minutes, most of the patients saw their blood pressure plunge at least seven percent.

Researchers believe the vitamin works by calming an overactive central nervous system.

Whether or not results such as these can be achieved with vitamin C pills is still unknown. Researchers say more studies are now needed.
