What is it?
With changing and adapting lifestyles, there has been seen an increasing deficiency in Vitamin D in human bodies. It is a fat soluble vitamin which is synthesized by the skin when exposed to sunlight. It is essential for maintaining a healthy immune system and strong bones. Research suggests that vitamin D (calciferol) deficiency may cause osteoporosis to autoimmune disorders, cardiovascular disease and potentially even cancer.* In fact, some even suggest that the lack of calciferol can cause obesity.*
How is it produced?
When our body is exposed to the sun, a substance called provitamin D3 reacts with the UVB in sunlight to form D3 which is transported to the kidney and from there to the liver where it is transformed into calciferol. Commercially it is available as Vitamin D2 (ergocalciferol) and D3 (cholecalciferol). D3 is the closest to natural vitamin D manufactured by our body. It is present in cheese, egg yolks and fish liver oils whereas D2 is present in mushrooms and yeast. Vitamin D3 is made from sheep wool. Crude lanolin is extracted from the wool of sheep and subject several chemical process to get cholecalciferol. Vitamin D2 is a synthetic version obtained by irradiating plant matter and yeast to get ergocalciferol. Latest research suggests that D3 is a far more preferred option in comparison to D2 which tends to have a shorter shelf life.
Supplement forms
Vitamin D supplements are available by themselves in capsules, soft gels, liquids or powder forms. They can also be part of other multivitamins. This supplement can be taken at any time; it will not inhibit its absorption or its effect. Ideally it should be taken with the largest meal of the day.
The recommended vitamin D supplement dose is 2000-10,000 IU per week. A word of caution while taking these supplements is overdosing because that could be potentially harmful and should be avoided.*
