This study tested whether an oak wood extract supplement called Robuvit® could help people recover faster after the flu. One group of recovering patients took the supplement (300 mg daily) along with standard care, while another group received standard care alone. After 3 weeks, the supplement group reported less weakness, better sleep, improved focus, and faster recovery after physical activity compared to the control group.
