15 May 2023 --- Researchers from the Vita-Salute San Raffaele University and IRCCS San Raffaele Hospital in Milan, Italy, have found that Long COVID risk increases when vitamin D levels are low. The research was presented at the 25th European Congress of Endocrinology in Istanbul, Türkiye (May 13-16). Including 100 hospitalized patients, 50 with and 50 without Long COVID, aged between 51 to 70 years old, the researchers measured vitamin D levels when admitted and six months after discharge. They found lower levels among those suffering from Long COVID than those who did not.
