According to a recent study published in the medical journal “The BMJ”, vitamin D supplements do not lower the incidence of COVID-19 or other acute respiratory infections, which suggests that prescribing these supplements to COVID patients may not be very helpful.
The findings are based on two sizable clinical trials, which show that raising vitamin D levels in individuals during the SARS-CoV-2 pandemic was not linked to immunity to COVID-19 or respiratory track infections.
“Advice should only be that ‘prescribe only when there is a deficiency’,” said Dr GC Khilnani, former head, pulmonology department, All India Institute of Medical Sciences, Delhi.
According to a professor at Sweden’s Karolinska Institute, Peter Bergman, vaccination is still the most effective strategy to protect people from Covid-19.
