Green oat preparations have been used since medieval times to address fatigue, poor concentration and irritable mood. Using a bioassay-guided development approach, IFF Health has scientifically substantiated and linked these effects to a selected green oat variety.
In a human study using electroencephalogram as a tool, Neuravena® intake has been associated with changes in brain activity based on effects in the left front temporal area of brain, an area known to be involved in cognitive tasks.
Effects of intake were explored using the Stroop color-word test, an accepted model for concentration and alertness. Statistically significant effects were linked to Neuravena® intake using a battery of tests selected to allow assessments across the major cognitive domains, i.e. concentration, executive function and episodic memory (COMPASS).
Green oat extract supplementation has further been reported to improve vasodilator function in systemic and cerebral arteries in older adults.
