What is Cholecalciferol?

Cholecalciferol, also known as Vitamin D3, is a type of Vitamin D which is produced by the skin when exposed to sunlight. Because the body produces it, Vitamin D3 is not a true vitamin, but it is usually considered a vitamin due to its importance in the human body.

No dose info can't even take

There is no way of knowing how much to take. Other packages I've purchased tell me how much is in ex; a tsp or 1/4 tsp. There is no such guidance here and until I can figure out how to measure properly, I can't use it.
