An optimal vitamin D intake can reduce the risk of premature death by 30% among people suffering from cardiovascular disease, according to a study.

New findings on vitamin D deficiency in the body

To carry out this study, the researchers analyzed for 12 years the medical data of 4,000 patients, with an average age of 62 years, suffering from cardiovascular diseases.

Our study shows that optimal vitamin D intake in the body substantially reduces the risk of premature death. Too low or too high a level of vitamin D could increase this risk.

Specialists’ recommendations

An optimal intake of vitamin D in the body is between 42 and 100 units per liter of blood. Values ​​below or above this level may increase the risk of cardiovascular disease, a risk factor for premature death.

However, with regard to obtaining an optimal level of vitamin D in the body, it is difficult to establish recommendations that are generally valid, according to the specialists.

The optimal amount of vitamin D in food supplements varies from person to person, depending on diet, sun exposure and the environment.

For example, in the Nordic countries the specialists recommend supplementing with 10 micrograms per day, while in the USA and Germany the specialists recommend between 15 and 20 micrograms daily.

“Even though the Nordic countries suffer from limited exposure to sunlight, they have a diet rich in fish. Fish and fish oil are important sources of vitamin D in the cold season,” explains the lead author of the study.

Accordingly, specialists recommend performing blood tests to determine the level of vitamin D in the body in order to determine which is the optimal measure to supplement the diet with vitamin D.

“We also need to consider that the level of vitamin D in the body varies by season. Thus, the results of blood tests in the cold months will not be similar to those performed in the warm months,” concludes the author.
