YES. Vitamin D is a "secosteroid" which means a part of it is converted to a steroid by the body. If you have any kind of underlying disease process involving a suspected bacteria/pathogen such as Lyme, CFS, MS, Fibro, and others DO NOT TAKE D. It will make you feel better initially (as all steroids do) but will allow the bacteria/pathogen to PROLIFERATE! This will increase your bacterial load and ultimately make you sicker! There are plenty of healthy people with low d. The action of D is corollary, not causative as current pop medicine would have you believe. There is a lot of ignorance out there. The D receptor is actually blocked or down regulated by the body if you have an underlying disease process going on. This is the your system's way of PROTECTING itself from increased inflammation. The bacterial load must be eliminated before the d receptor will work properly again. People are not recognizing the steroid action of D. If you go to ILADS.COM and punch in steroid it will tell you NOT TO TAKE THEM. However they do not realize that D is A STEROID. Hope this helps!
cholesterol
Cholesterol is the precursor of bile acid, steroid hormones and vitamin D.
Cholecalciferol is a steroid hormone that regulates body levels of calcium. It is a form of Vitamin D. Parathyroid hormone increases the concentration of calcium in the blood.
Yes, vitamin D is derived from cholesterol.Hint: "Read your Physiology textbook.
No UV light can not be treated as vit D precursor as it only provides the energy in the form of radiation for the reaction to take place. It is the steroid molecule present in dermis which is precursor for vitD synthesis.

No. Cholesterol is a lipid and is a precursor to vitamin D and steroid hormones.
Vitamin D alone is not believed to decrease Asthma. Vitamin D has been shown to increase the effect of Steroids when used to treat asthma. Hear is a link that will explain the use of vitamin D and Steroid in asthma treatment http://pittsburgh.cbslocal.com/2011/04/21/can-vitamin-d-help-asthma-sufferers/

Vitamin D is a fat soluble vitamin, and functions as a steroid hormone. What steroid hormones do is go in to the nucleus of cells, and alter gene expression, that is turning genes on or off, or simply giving them a nudge in either direction.Other steroid hormones include testosterone, aldosterone and many more. Being deficient in a hormone is pretty serious, and Vitamin D is no exception.What this implies, is that people who don't get enough sun year round are probably deficient in a major hormone in their bodies. A hormone, whose lack of has been implicated in some serious illnesses
Vitamin D is produced by ultraviolet radiation on your skin. The UV light converts a precursor molecule to vitamin D.
Vitamin D is synthesized at the skin. It is synthesised by the reaction between the sun's rays and estrogen (Actually look up to be sure, it could be a different steroid very similar to estrogen)
