The Tea Effect

Tea has long been known for its ability to revive, relax and refresh at the
same time. Research is now examining how tea may have these effects.

What is it?

Drinking 2-3 cups of tea has been shown to have a positive effect on
maintaining alertness throughout the day.1 Tea contains less caffeine
than coffee, however even when caffeine levels are matched, the
effects of tea and coffee on mood are very different, suggesting there is
another component in tea that may be responsible.1, 2

Theanine

Theanine is an amino acid found almost exclusively in tea. Early
research suggests that 50mg Theanine naturally stimulates activity in
the brain known as alpha waves, which are associated with a relaxed
but alert mental state.3, 4

A typical cup of Lipton tea contains 14-18mg Theanine.5

Did you know?

Isaac Newton was actually drinking a cup of tea at the time he discovered the universal law of gravity.
