Vitamin D, also known as the sunshine vitamin, has three forms. They are Vitamin D 1 (calciferol), Vitamin D 2 (ergocalciferol), and Vitamin D 3 (cholecalciferol). Vitamin D 2 is the most common added to milk and supplements however Vitamin D 3 is the most absorbable. Vitamin D needs a diet including good fats to be bioavailable. Cod liver oil is the highest source of D coming in with over 2000 IU for 2 Tablespoons. A six oz. piece of salmon is next with just over 600 IU. Suggested intake of D is 200 IU in youth through 40’s with a jump up to 400 IU in your 50’s and 600 IU in your 70’s.

Vitamin D is necessary for the absorption of calcium. Also if there is not enough Vitamin D, calcium can leach from the bones and form blockages in arteries. This is why Vitamin D has been linked to better heart health especially for those over 40. Low levels of Vitamin D have also been seen in those suffering with diabetes. It plays an important role in good immune function, hence the problems of cold and flu season when we have fewer hours of daylight, and tend to be inside due to the cold weather. Need for supplementation has been documented by several European studies during those winter months.

This has been one of the most overlooked vitamins over the last several decades. However the research is conclusive that Vitamin D is an essential nutrient to support your overall health and well being.
