Extract from French Oak Wood Shown to Improve Sleep
Not getting enough sleep can result in an increase in oxidative stress. A recent study suggests that taking a French oak wood supplement may improve sleep quality and mood in people with insomnia and high oxidative stress.
Participants in the study included 40 middle-aged people with high oxidative stress who had complained about fatigue, insomnia, and mood alterations. All of the participants followed the same standardized management plan for 8 weeks, which included exercise, diet plan, avoidance of sugar and salt, and increased sun exposure. They also were given the choice of being part of the intervention group and consuming three capsules of 100 mg of French oak wood extract per day or to join the control group. Twenty-two joined the control group and 18 joined the intervention group.
The Regensburg Insomnia Scale, Fatigue Severity Scale, and Brief Mood Introspection Scale were used to evaluate the participants’ symptoms of insomnia, fatigue, mood fluctuations, and oxidative stress at the beginning of the study period and at the end.
At the end of the study period, the French oak wood group showed improvements in mood, oxidative stress, fatigue, and insomnia, including improvements in 13 out of 16 items measured by the Brief Mood Introspection Scale. There were no changes in the placebo group.
Researchers from Chieti-Pescara University led the study. It was published in the August 2018 issue of the Journal of Neurosurgical Sciences.
