Vitamin D Connection

Modern research brings Vitamin D as a focus for health and encourages taking it in higher dosage than it is usually taken. Vitamin D is a unique, fat soluble vitamin and not a stranger. It is produced by your own body as you are exposed to the sun. The amount depends on the time of day, season, latitude and skin pigmentation (darker skins make less D).

Only a few foods supply vitamin D. Whole milk is fortified with Vitamin-D and contains 100 IU(International Units) per cup.

The latest research reveals that at a certain dosage, Vitamin D works at molecular level in turning on/off of the genes and producing antibiotics in the cell. Most recent surveys indicate that many people are deficient in Vitamin D, especially those who are over 60, live in northern states, and have darker skins. In North America, Vitamin D levels in blood drop drastically during winter months. Many young people have low blood levels of D according to some recent surveys. Obesity and some cancers develop in individuals with reduced blood levels of Vitamin D.

Recent studies indicate that people taking D supplements daily usually 400 to 800 IU had a 7% reduction in total mortality rate. Some experts like Dr. Edward Giovannucci of Harvard and Dr. Bruce Hollis of the Medical University of South Carolina, recommend screening for Vitamin D. Dr. Hollis says “ Everyone needs to know his or her level of 25-hydroxy Vitamin D” because of its potentially protective effect against chronic diseases. The amount of D in a multivitamin (usually 400 IU) and /or from exposure to the sun for short periods may not be enough to reach desirable levels. We all differ from person to person in our abilities to make and utilize D. Therefore it is important to be tested clinically.

The blood levels of 30-40 ng/ml of 25-hydoxyvitamin D are desirable. However, many people specially over 60 and during winter, have levels of 20 ng/ml or below .There is serious debate, however, even on the optimal blood levels. Dr. Hollis believes that at least 50-60 ng/ml is a better goal.

So, let us increase awareness of our Vitamin D levels. Check with your physicians and raise your optimal health with knowledge.
