About the VitaminD3 microcapsule

VitaminD3World's microcapsule is tiny making it very easy to swallow. It has been formulated to ensure that it disintegrates rapidly to ensure absorption of Vitamin D3.

Because of its size and formulation, it can be swallowed, very easily.

We presently offer the micro capsule in two strengths, 2000 and 5000IU with 300 microcapsules per bottle.

Our products are manufactured in the USA in a GMP compliant plant. (GMP refers to FDA's guidelines on Good manufacturing practices)

Vitamin D3 is sourced by washing lambs wool (from Australia) to retrieve lanolin from which the precursor is extracted and converted to D3 by exposure to ultra violet light-this is exactly how vitamin D is produced in the human body.

This form of Vitamin D3 is considered suitable for vegetarians as the animals are not killed. The lamb's wool is simply washed to extract lanolin which supplies the precursor molecule from which Vitamin D3 is produced.

Vegans, who will not consume anything derived from animal products have a particular problem. There is no source of Vitamin D3 that does not originate in animals. Their only option is to use Vitamin D2 which is derived from plants. However studies have shown that D2 is only 30% as efficient as D3 in raising active Vitamin D levels in humans. Their only other alternative is to expose themselves to sufficient sun light.
