More evidence of Vitamin D in fight against Covid

 Epoch Times:

Since the start of the pandemic, natural supplements have been a bone of contention with researchers, pharmaceutical companies, doctors and health experts. Newly published data again support past research that vitamin D has a significant impact on COVID-19.

Vitamin D was discovered in the early 1900s. Work by Sir Edward Mellanby from Great Britain and Elmer McCollum from the University of Wisconsin demonstrated that vitamin D could cure rickets. In the early 1970s, 25-OH-D3 was identified as scientists focused on the endocrine system, and the function that vitamin D has in the body.

Your body is capable of producing vitamin D with exposure to sunlight. In fact, with adequate exposure, your skin can produce enough vitamin D to support your health. Early research showed that too little vitamin D led to poor calcium homeostasis. In turn, this can lead to osteoporosis, osteomalacia and rickets.

Multiple studies have since demonstrated that a deficiency “is associated with increased risk and greater severity of infection, particularly of the respiratory tract.” While nearly every study finds a relationship between vitamin D and upper respiratory infections, not all find that vitamin D has the same impact on the infections.

One factor that may influence the varied results is how the researchers measure the intervention and data. In other words, are they measuring the amount of supplementation being given or are they looking at the vitamin D blood levels demonstrating deficiency against the impact on infection?7

A UK study early during the pandemic found an absence of Vitamin D in people who became severely ill with the disease.  They found this to be especially the case with people with dark skin.  I suspect that people in the UK probably have less exposure to the sun than those in Florida or Texas.
