L-Theanine is a naturally occurring amino acid found in tea leaves that supports a calm, balanced state without causing drowsiness. L-Theanine helps ease feelings of stress and nervous tension associated with daily demands, while also reducing irritability by supporting healthy neurotransmitter activity. Research shows that L-Theanine can enhance focus, attention, and mental clarity, and may help counter the jittery effects often associated with caffeine. L-Theanine is suggested to take at night to help with calm before sleep.
