French Oak Wood Extract Aids Flu Recovery

The May 2018 issue of The Journal of Sports Medicine and Physical Fitness published the finding of European researchers of a benefit for Robuvit® French oak wood extract in recovery from influenza.

While the malaise and fatigue that follow the flu are well known to most individuals, research has also revealed an increased risk of bacterial infection and heart attack during this period.

The study enrolled 38 patients between the ages of 65 and 75 during the 3 days that followed a 7 to 10-day bout of influenza. “Individuals over the age of 65 are the most susceptible group for complications with the flu,” commented natural health physician and author Dr Fred Pescatore. “Since this age group typically has a weakened immune system, it takes even longer to fully recover from nagging flu symptoms like fatigue and feeling of weakness.”

Subjects received a standard management plan with or without daily supplementation with 300 milligrams French oak wood extract for 3 weeks. After 10 days, participants who received oak wood extract experienced improvement in heart rate, oxygen saturation, strength and recovery after exertion compared to the unsupplemented group. At the end of the 3-week treatment period, strength was recovered by 85% of supplemented subjects in comparison with 60% of the control group. Sleep quality, exertion recovery, attention span, and working and concentration capacity also improved to a significantly greater extent in the supplemented group.

“These findings show promising results for patients to rebuild strength after a bout of the flu,” Dr Pescatore concluded. “Robuvit®’s natural antioxidant properties reduce oxidative stress and its anti-fatigue benefits help to promote energy during flu recovery . . . It’s particularly important for seniors with weakened immune systems who are at-risk of developing other ailments during their recovery.”
