Due to its properties and mechanism of action, it can be combined with caffeine in a 1: 1 ratio. If you rank among the coffee lovers and want to dampen the possible rapid onset of caffeine, l-theanine supplements may be the right choice for you.  A single espresso shot contains, on average, 70-100 mg of caffeine. It is advisable to combine such amount with approximately one capsule of l-theanine. Similarly, you can use l-theanine in combination with your favourite energy drink or pre-workout that contains caffeine. It is especially suitable during periods of increased stress or if you have problems with sleep. Additionally, l-theanine belongs to a group of natural nootropics, which are, in general, substances that affect mental performance.
