Hello,
I guess I shall clarify my question and can you give an answer in lay terms since the majority of the population does not speak the medical language. You wouldn’t speak Russian to a Spanish speaking person would you?

This is an excerpt from your answer
"Sun-to-skin, supplement and diet:
Cholecalciferol -- biologically inactive substrate, pre-hormonal == the one-and-only natural "vitamin D" (vitamin D3"
So I looked up the dictionary definition of Hormone and nutrient they are as follows:
Nutrient
1. nourishing; providing nutrition.

2. a food or other substance that provides energy or building material for the survival and growth of a living organism.

Hormone
a chemical substance produced in the body which has a specific regulatory effect on the activity of certain cells or a certain organ or organs.
My understanding from the definition nutrients are consumed (external source)and hormones are produced in the body (internal source)

So my question the substance that is called Vitamin D is it a Nutrient or a Hormone?
What is , 1,25-dihydroxyvitamin D3 and its source? Simple lay term please?
What is 25-hydroxyvitamin D and it source?
