Did you know Tea contains a very beneficial supplement called L-theanine?
A study published in 2003 showed that the immune system of tea drinkers was higher than that of coffee drinkers, this is thought to be because of the L-theanine. L-theanine is a non-essential natural amino acid which can help improve mood, reduce stress, and help focus particularly when combined with caffeine. According to experts who've done their research, L-theanine is thought to increase alpha wave brain activity. This is the kind of brain activity when your mind is alert, but not stressed. The supposed most desirable awake state. So mix up your drink cycle by exploring some new teas. L-theanine is in all white, green, and black tea.
