Another study conducted by a hospital in Spain revealed a connection between low vitamin D and a person’s vulnerability to COVID.

Researchers working with the University Marques de Valdecialla located in Santander, Spain reported that 82% of the COVID patients they surveyed had low levels of vitamin D.

CTV News reports:

TORONTO — More than 80 per cent of COVID-19 patients at a hospital in Spain had a vitamin D deficiency, according to a new study.

Researchers at the University Hospital Marques de Valdecilla in Santander, Spain looked at the vitamin D levels of 216 patients admitted to hospital for coronavirus treatment between March 10 and March 31.

For the study, the 216 hospitalized patients’ vitamin D levels were compared to those of a control group of 197 people of similar age and sex from a population-based cohort in the same geographical area.

This shouldn’t surprise us, because several studies have suggested that people most vulnerable to COVID, including those in nursing homes, have low levels of vitamin D.

Study: vitamin D supplements also reduce cold and flu infections

Studies are also showing that taking vitamin D supplements also reduces respiratory infections such as colds and the flu by upwards of 50%.

Harvard University Gazette reports:

A new global collaborative study has confirmed that vitamin D supplementation can help protect against acute respiratory infections. …

“Most people understand that vitamin D is critical for bone and muscle health,” said Carlos Camargo of the Department of Emergency Medicine at Massachusetts General Hospital (MGH), the study’s senior author. “Our analysis has also found that it helps the body fight acute respiratory infection, which is responsible for millions of deaths globally each year.”

Their study revealed that taking vitamin D supplements regularly cut risk of infection by 50%.

The investigators found that daily or weekly supplementation had the greatest benefit for individuals with the most significant vitamin D deficiency (blood levels below 10 mg/dl) — cutting their risk of respiratory infection in half — and that all participants experienced some beneficial effects from regular vitamin D supplementation. Administering occasional high doses of vitamin D did not produce significant benefits.
