Trial finds vitamin D supplements don't reduce COVID severity but could reduce long COVID risk

medicalxpress - In a large, randomized trial, researchers at Mass General Brigham found that high-dose vitamin D3 did not reduce COVID-19 infection severity, but may impact long COVID outcomes. Results of the study are published in The Journal of Nutrition.

AI Summary: A large randomized trial found high‑dose vitamin D3 did not lower acute COVID‑19 severity but revealed a surprising signal: supplementation may reduce the risk of developing long‑COVID. The result complicates the vitamin D narrative — not a cure, perhaps a modest shield against persistent post‑infectious symptoms worthy of further investigation.
