Common vitamin could bring relief from long COVID symptoms, study suggests

Vitamin D supplements may offer researchers a new clue about lingering COVID symptoms that persist after infection, according to a new study.

Researchers at Mass General Brigham examined whether high doses of vitamin D could influence COVID-19 outcomes, including the risk of developing long COVID, a condition in which symptoms such as fatigue, shortness of breath and brain fog continue weeks or months after the initial infection.

The findings were published in The Journal of Nutrition.
