FAQ

NPC's Vitamin D3 micro tablet is tiny and tasteless. It has been formulated with cellulose, an inert plant material that rapidly absorbs water. This ensure that the tablet disintegrates rapidly to ensure absorption of Vitamin D3.

Because of its size and formulation, it can be swallowed, simply crunched up in the mouth or placed under the tongue until it disintegrates.

We presently offer the micro tablet in three strengths, 1000 and 2000IU with 400 micro tablets per bottle and 5000IU with 200 micro tablets 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.
