Scientists studied vitamin D supplements for COVID-19 and found a possible connection to long COVID symptoms. The study included over 2,000 adults in the US and Mongolia.

Scientists have been investigating whether taking vitamin D supplements can help with COVID-19 infections. A recent large-scale study led by Mass General Brigham looked into this further. The researchers gave high doses of vitamin D3 to some participants and a placebo to others. They found that taking vitamin D did not make COVID-19 infections less severe, but it might have an impact on long COVID symptoms.

The study included over 2,000 adults in the US and Mongolia who had recently tested positive for COVID-19. The participants took either vitamin D3 or a placebo daily for four weeks. The researchers looked at how well the participants were doing during this time and eight weeks after their initial infection.

They found that taking vitamin D did not improve healthcare utilization, death rates, or symptom severity compared to the placebo group. However, they noticed something interesting when they analyzed participants who consistently took the vitamin D supplements. These individuals seemed less likely to report persistent symptoms eight weeks after infection.

The study's senior author, JoAnn Manson, said that long COVID continues to affect people's lives and that further research is needed to understand whether vitamin D supplementation can reduce the risks and severity of long COVID.

Why It Matters

This study matters because it highlights the importance of understanding long COVID symptoms. Many Indians are affected by COVID-19, and this research could lead to new ways to manage its lingering effects.
