Vitamin D, Calcifediol and CoViD 19.

[S11m]

We spend millions on minerals, vitamins and food supplements, but a good diet should provide almost all we need.

A few millennia ago we were naked in the tropics - and sunlight on our skin produced plenty of Vitamin D ...but, in temperate or colder latitudes, in winter, we do not get enough Vitamin D from sunlight.

Vitamin D has many functions in the body. Years ago, my doctor prescribed Vitamin D for SAD (Seasonally Affected Disorder).

Vitamin D enhances immunity, and there have been studies on how it helps prevent CoViD 19, so the NHS now provides it free for vulnerable groups:

"Use this service to get free daily vitamin D supplements if you're at high risk (clinically extremely vulnerable) from coronavirus (COVID-19)."

There have also been studies on the use of Vitamin D in the treatment of CoViD 19...

The Viral replication stage of CoViD 19 mostly occurs within a few days of the onset of symptoms, and, Dr David Campbell says, it takes the body longer than that to convert Vitamin D into the activated form (Calcifediol). This is one reason why most studies of treatment of CoViD with Vitamin D have not been very successful.

See the picture above of the East Virginia Medical School chart re the viral replication stage of CoVid 19:

An as yet un-peer-reviewed Lancet pre-print article about a Spanish study indicates that treatment of CoViD 19 with Calcifediol on admission to hospital results in significant reductions in mortality and ICU admissions.

I wonder if Pharmacists could supply Calcifediol "at the onset of symptoms" results might be even better?

Dietary Vitamin D and Vitamin D produced in the skin has to be converted (in the liver) into Calcifediol, so Calcifediol treatment raises levels of the active form of Vitamin D in time to reduce viral replication.

This video by Dr David Campbell discusses this (and another) study:
