Hoboken, NJ—Daily supplementation with Robuvit, a French oak wood extract, improves energy, enthusiasm, and physical and mental health associated with vigor, according to a new study published inPanminerva Medica.

A survey from the University of Michigan has found that 38% of Americans report feeling tired with little energy as a result of current events, and 23% report feeling little interest in daily activities, according to a press release.

"Decreased vigor is often associated with sleep disruption, exhaustion, and getting older. It can be a symptom of a larger health issue such as chronic fatigue syndrome, post-traumatic stress disorder, or mononucleosis," said natural health physician, Dr. Fred Pescatore, in the press release. "Prolonged stress and anxiety, like what many of us have faced during the pandemic and economic hardship, can result in decreased energy, decline in activity, and the related mental and mood effects—such as lack of enthusiasm and feelings of apathy—which are related to decreased vigor."

The study examined 40 male participants between the ages of 50 and 65 who reported decreased vigor and stamina as well as high levels of oxidative stress. Researchers evaluated participant characteristics associated with diminished vigor such as fatigue, apathy, and weakness. A control group followed a standard management protocol—healthy diet, exercise, and supplementation with potassium gluconate and vitamin C—while a trial group followed the same protocol and also supplemented with 300mg of Robuvit daily.

Participants in the Robuvit group reported:
  • 55% increase in energy (compared to 5% increase in the control group)
  • 75% improvement in activity level (compared to 35% in the control group)
  • 67% increase in enthusiasm (compared to no increase in the control group)
  • 80% reduction in feelings of apathy (compared to 40% reduction in the control group)
  • 45% increase in physical and mental health (compared to no increase in the control group)
  • 15% reduction in oxidative stress
Previous research has found that Robuvit may help improve mood, fatigue, and insomnia; research in 2013 and 2015 found that Robuvit may be beneficial to those experiencing general fatigue or chronic fatigue syndrome, the press release notes.

"This study shows promising results for those struggling with low energy and vigor, which is particularly prevalent during the pandemic," said Dr. Pescatore. "This research presents meaningful findings and participants felt better after only four weeks of supplementing with all natural Robuvit and no unwanted side effects were observed in any participants."
