While it contains less caffeine, green tea is rich in other nootropic compounds like l-theanine and epigallocatechin gallate (EGCG). These compounds promote relaxation and improve attention. They can also support memory and attention span. EGCG is also able to cross the blood-brain barrier, which can help to fight neurodegeneration.
