Soram Khalsa, M.D., sheds new light on the power of this long-forgotten vitamin. He reveals how to recognize signs of Vitamin D deficiency, which has reached epidemic proportions in North America, and then shares insights from his Beverly Hills medical practice, where he normalizes his own patients’ Vitamin D levels for their optimal health.

Recent, groundbreaking medical research has made a connection between Vitamin D deficiency and 17 types of cancers, including breast, colon, and prostate. Illnesses such as influenza, diabetes, multiple sclerosis, and coronary heart disease have also been connected to a lack of this vitamin. Until not too long ago, not getting enough Vitamin D (the sunshine vitamin) was only associated with rickets, the childhood bone disease.

 

Recent ground breaking research clearly demonstrates a wide range of incredible health benefits Vitamin D may provide, yet most people continue to be low in Vitamin D—despite the vitamins they take, the food they eat, the milk they drink or the sun exposure they get.

* Milk including non-fat, reduced fat, whole or vitamin D fortified

* Margarine

* Cereals

* Egg

The Need for Increased Amounts

Since obtaining sufficient amounts of vitamin D in the diet can be quite difficult, many people now consume vitamin D fortified foods in order to maintain a healthy dose of the vitamin. There are some groups however who need increased amounts of vitamin D:

* Breastfed infants because vitamin D cannot be supplied by breast milk alone

* Older people due to the fact that synthesis of vitamin D decreases with age and the ability of the kidney to convert vitamin D diminishes

* People with limited sun exposure especially those living in northern latitudes, those wearing robes or head covers or those with occupations that prevent them from having sun exposure

* People with dark skin as more skin pigments like melanin reduces the ability of the skin to produce vitamin D.

* People with fat malabsorption conditions such as Crohn’s disease, cystic fibrosis, liver and celiac disease or patients who have undergone surgical removal of any part of the stomach or intestine.

* People who are obese. An increased amount of subcutaneous fat can snatch more of the vitamin D and somehow alter its release in the circulation.

Interaction of Vitamin D with Prescribed Drugs

Vitamin D supplements have the tendency to react with certain types of prescription medications. These include the following:

* Steroids or corticosteroid medications like prednisone which can cause decreased calcium absorption and also damage the vitamin D metabolism process.
* Weight-loss medications such as orlistat and cholesterol-lowering drugs like cholestyramine also decrease the absorption of vitamin D and other fat-soluble vitamins.
* Phenobarbital and phenytoin increases vitamin D metabolism and decreases calcium absorption.
