Tea Advisory Panel - Alertness / Fatigue

Alertness / Fatigue

Findings from various studies have found that the drinks containing a combination of L-theanine and caffeine may improve mental attention¹. Tea is the main dietary source of L-theanine and also contains a moderate amount of caffeine (approx. 50mg per cup).

Improvements were observed not only in visual attention span but also in hearing attention span in a 2010 study¹and this is supported by an earlier research review,² which investigated the health aspects of caffeine further. This is emerging data, suggesting that l-theanine and flavonoids can support brain and mental function but more research is needed.
