- FACT: Kidney is the primary way to activate vitamin D
- FACT: When the Kidney has problems, there is less active vitamin D (Calcitriol) for the body
- FACT: When the Kidney has problems, there is increased death due to many factors - many of which are associated with lack of Calcitriol
- FACT: There are many on-going intervention clinical trials trying to determine how much of what kind of vitamin D is needed to treat the problem
- FACT: One Randomized Controlled Trial has proven that Vitamin D treats CKD
- FACT: Taking extra Vitamin D, in various forms, does not cause health problems - even if poor kidney
- Suggestion: Increase vitamin D getting into body now - and increase co-factors so that the vitamin D can be better used
Sun, UV lamp, Vitamin D supplement - probably > 5,000 IU,
Calcitriol - which bypasses the need for the kidney to activate vitamin D
Problems with Calcitriol however: typically only lasts for a few hours, also, possible complications

It is amazing that such excellent results were buried in the paper. They were not in the title nor abstract.
This is the result of about 10 trials with about 5,000 kidney disease patients.
Note: some of the trials were terminated as they felt it morally wrong to not give vitamin D to all of the Kidney patients

Imagine how many fewer deaths if had gotten the right amount of the right kind of vitamin D, along with Magnesium
A guess (based on NO data) 40% of vitamin D is activated by the kidneys
Vitamin D Deficiency Vicious circles a portion of the chart follows
Low vitamin D ==> Diabetes ==> Kidney failure
Kidney failure ==> Low Vitamin D and poor regulation of Magnesium
Activated vitamin D decreases with worsening of CKD
Perhaps 120% increase incidence in a decade
Dark skinned people (with less vitamin D) have 3X more incidence of CKD
- It remains something of a mystery even now as to why we have two kidneys.
- The kidneys process about 190 quarts of water and 3.3 pounds of salt. daily
- Between the ages of forty and seventy, kidney filtration capacity drops by about 50 percent.
