Having trained at Imperial College London, Dr Davies returned to the field of research to look into the coronavirus pandemic. Collaborating with leading scientists, they discovered startling results.
Working alongside Dr Joanna Byers and Dr Attila R Garami, Dr Davies came to the conclusion that vitamin D deficiency is linked to severe COVID outcomes.
In a research paper – yet to be peer-reviewed – they “analysed global daily reports of fatalities and recoveries” from COVID-19.
They found “a striking correlation between COVID-19 severity and latitude,” as the northern hemisphere – where seasonal vitamin D deficiency is rife – saw more tragic cases of coronavirus.
“Peer-review takes up to a year in normal conditions,” asserted Dr Davies – and we are yet to be 365 days into this pandemic.
Dr Davies is adamant “vitamin D deficiency is the dominant risk factor in severe coronavirus disease”.
Vitamin D
Dr Davies says vitamin D is “critical to immune function”. When vitamin D levels are high, “the innate immune system is strong”.
Speaking about SARS-CoV-2 – the virus that causes the disease COVID-19 – he explains how the coronavirus invades the body.

The current NHS guidelines suggest everybody needs to be taking 400IU of vitamin D daily between October and early March.
Yet, Dr Davies insists this recommendation needs to be upped by 10 percent.
He suggests that 4,000IU daily is what is needed to keep people safe from coronavirus.
“Most researchers believe that 10,000 IU daily is safe for most adults,” he adds.
Dr Davies says the government’s recommended daily allowance doesn’t “offer immune system protection against infection and disease”.
For those fearful of hypercalcaemia, Dr Gareth says it’s “rare and is easily treated”.
“The tiny risk of hypercalcaemia must be balanced against the enormous risk of disease and death presented by COVID-19.”
What’s hypercalcaemia?
The NHS explained hypercalcaemia occurs when there’s too much calcium in the body. This can weaken the bones, and damage the kidneys and heart.
Dr Davies assures “4,000IU daily is perfectly safe and suited to almost all adults”, only advising children and underweight adults to take less.
Absolutely certain of the benefits of vitamin D supplementation, Dr Davies and a growing list of scientists are “calling on all governments to immediately increase the use of vitamin D to combat COVID-19”.
He believes vitamin D supplements “should be the number one tactic in global pandemic management strategies”.
“We know that vitamin D reduces infection risk and stops serious disease from developing in most people.”
