A recently published study found that supplementation with the French oak wood extract Robuvit supports vigor in older men experiencing reduced energy levels.
A recent study published in Panminerva Medica1 found that supplementation with the French oak wood extract Robuvit (from Horphag Research, based in Hoboken, NJ) supports vigor in older men experiencing reduced energy levels. In the study, 40 men between the ages of 50 and 65 were assigned to receive either standard management (SM) or SM in combination with 300 mg of Robuvit, for four weeks. SM was a regimen of healthy diet, exercise, and supplementation with potassium gluconate and vitamin C. Results showed that while both groups saw improvements, those taking Robuvit had significantly high scores for vigor-related items compared to SM alone.
Specifically, subjects in the Robuvit group saw a 55% increase in energy (compared to 5% in the SM group), a 75% improvement in activity level (compared to 35% in the SM group), a 67% increase in enthusiasm (compared to none in the SM group), an 80% reduction in feelings of apathy (compared to 40% in the SM group), and a 45% increase in physical and mental health (compared to none in the SM group). Additionally, those taking Robuvit also saw a 15% reduction in oxidative stress compared to SM alone, after four weeks.
