Re: Amy Proal and the Trevor Marshall - blecch!

Hello John,
our paths cross once again concerning Vitamin D.

DQ has eloquently and articulately expressed my own opinion in this thread.

It seems strange to me that your stance on Vitamin D is as it is, because the overwhelming scientific evidence and research points in one direction, and one direction only: most people are deficient from what is considered to be sufficient or optimal levels.

Just to clarify.......

Cholecalciferol (D3) is commonly referred to as a hormone: which it isn't. It is actually a prehormone. In fact, it is no more of a hormone than cholesterol is. It is very similar to cholesterol. For example, some of the cholesterol you eat is turned into hormones: estrogen, testosterone, progesterone, etc. Some of the cholecalciferol from your skin, or from supplements you take, will be turned into hormones by the body. So cholecalciferol is no more of a hormone than is cholesterol.

However, some of your cholecalciferol (from sunlight-exposure or supplements) will be transformed into calcidiol via the Liver, and then calcitriol via the kidneys: it is only the latter which is considered to be a very potent "steroid" with powerful anti-cancer properties.

Also, if any calcidiol is left over from the Liver, and the kidneys are receiving all the calcidiol they need to maintain serum calcium levels.......then calcidiol is able to take another pathway, one that leads directly to the cells. These are the autocrine (inside cell) and paracrine (around the cell) functions of the vitamin D system.

If you only have a small amount of calcidiol (formed from cholcalciferol via the Liver) in your blood, virtually all of it goes to your kidney, which then makes extra calcitriol to keep your serum calcium levels from falling. This means that almost no calcidiol gets to your tissues to make tissue calcitriol.

But when the body has an abundance of cholcalciferol, the left over calcidiol (from the Liver) goes to the many cells in the body "directly", which are then able to make their own calcitriol to fight cancer.
In fact, the cells appear to make as much calcitriol as they can. The more calcidiol they get, the more calcitriol they make. The manufacture of calcitriol in the tissues is unique. Every single cell in the body has receptors for D.

Vitamin D as being Immunosuppressive?........
