This potent vitamin may be the answer to arterial stiffness

According to a study from the Medical College of Georgia at Augusta University, This potent vitamin may be the answer to arterial stiffness — vitamin D.

Rigid artery walls are an independent predictor of cardiovascular- related disease and death and vitamin D deficiency appears to be a contributor, says Dr. Yanbin Dong, geneticist and cardiologist at the Georgia Prevention Institute at the Medical College of Georgia.

In the first randomized trial of its kind, the researchers found that vitamin D supplementation significantly improved arterial stiffness.

The study was published in the journal PLOS One.

Participants taking 4,000 international units — more than six times the daily 600 IUs the Institute of Medicine currently recommends for most adults and children — received the most benefit, says Dr. Anas Raed, research resident in the MCG Department of Medicine and the study’s first author.

The dose, which is considered the largest, safe dose by the Institute Of Medicine reduced arterial stiffness the fastest — 10.4 percent in four months. “It significantly and rapidly reduced stiffness,” Raed says.

According to a piece in Scientific American, vitamin D deficiency has soared in the U.S:

Between 1988 and 1994, 45 percent of 18,883 people (who were examined as part of the federal government’s National Health and Nutrition Examination Survey) had 30 nanograms per milliliter or more of vitamin D, the blood level a growing number of doctors consider sufficient for overall health; a decade later, just 23 percent of 13,369 of those surveyed had at least that amount.

To get your daily dose of vitamin D it is recommended to do the following:

‣ Eat Wild Alaskan Sockeye Salmon
‣ Take Vitamin D supplements
‣ Get daily exposure to sun (about 10 minutes). Do not forget to wear a sunscreen.

Some other good food sources of vitamin D are sardines, tuna, oysters, shrimp, eggs, and mushrooms.
