Vitamin D deficient diseases and magnesium deficient vitamin D resistant diseases

A vitamin D deficiency was first recognized clinically in rickets (1920s).
Many decades later magnesium deficient vitamin D resistant rickets was described.
Magnesium-dependent vitamin-D-resistant rickets (1974)
[pubmed.ncbi.nlm.nih.gov]
Now the spectrum of vitamin D deficient diseases has markedly expanded beyond rickets.

Now compare the above with the expanding list of just magnesium deficient CNS diseases. There seems to be a lot of overlap.

Looks like there’s a very significant subset of vitamin D deficient/refractory diseases, which owe their severity to an additional magnesium deficiency.
Interest in vitamin D is ramping up.

And it's not exactly a secret that it takes Mg to make vitamin D.

Unfortunately even the spate of recent papers connecting vitamin D deficiency with severity of COVID-19 rarely mention magnesium deficiency.
And there’s a growing number of people that appear to be both vitamin D deficient and Mg deficient.

None of these recent articles touting the benefits of vitamin D even mention magnesium.

Here's an example of how knowledge is being suppressed and fear sown in its stead by NICE (National Institute for Health and Care Excellence)

NICE (UK) is not nice; more like CRAP (Can't Really Analyze Pneumonia)
There’s a ton of literature out there praising the benefits of vitamin D in many diseases and only a few articles that are neutral. Could it be that the benefits of D in all these studies would have been even greater had they excluded the magnesium deficient vitamin D resistant?

President Trump is being given Vit. D, zinc and Melatonin, good to hear. Hopefully he will recover fully.
