Choose White or Green Tea

Not like black tea, green and white teas are mildly brewed and weren’t oxidized during the process which means that they have high levels of l-theanine, a known relaxing amino acid present in tea. A brain-scan study conducted at Oxford University showed that levels of alpha waves which are associated with the feeling of relaxed yet alert were high in individuals who consume drinks containing 50mg of l-theanine as compared to those who only drink water. The brewing process will affect the level l-theanine so drink a cup or two. On days where you have low-energy, drink tea even if have already had coffee. In another British research, individuals that were administered with doses of l-theanine and caffeine testified being less tired and they have increased speed during tests on attention and memory.
