✔️NATURAL SLEEP, RELAXATION AND FOCUS SUPPORT, MADE FROM GREEN TEA. L-theanine, an amino acid commonly found in green tea, offers several notable benefits. L-theanine has a calming effect on the mind- by increasing alpha wave activity, L-theanine promotes relaxation and helps manage symptoms of stress. This makes it an excellent natural option for individuals seeking a sense of tranquility and mental clarity.
