Belcaro, G, Cornelli, U, Luzzi, R et al.·Panminerva medica·2014
This small study tested whether a supplement made from French oak wood extract (Robuvit®) could help people with chronic fatigue syndrome (CFS) when combined with a structured management plan. About half of the 91 participants received the supplement for 6 months while the other half followed the management plan alone. The supplement group showed greater improvements in fatigue symptoms and mood compared to the management-only group, and no side effects were reported.
