A recent study published in The Journal of Medicinal Studies (April 2011) suggests that daily supplementation with green tea extracts may boost mental alertness and enhance memory. Researchers who conducted the randomized, double-blind, placebo-controlled study in Korea concluded that a combination of green tea extract with L-theanine “should be considered a potential nutraceutical candidate for enhancing cognitive performance.”1

Studies have already shown the positive impact such extracts may have on cognitive health, but another component called L-theanine, an amino acid, is believed to function as a relaxant, helping to reduce stress and improve sleep quality at an effective dose (between 100-200 mg/day). The benefits that a combination of these extracts and L-theanine may provide for improving mental health is the subject of numerous research studies. Such studies continue to spur a booming market growth for such extracts. Since a health-benefiting dose of L-theanine cannot be obtained from drinking freshly brewed tea green, business owners like you can tap into the market for cognitive health supplements by manufacturing well-formulated green tea supplements with the help of an experienced supplement manufacturer.
