Theanine, often referred to as L-theanine as that is the predominant isomer of theanine, is an amino acid commonly found in tea leaves, particularly in green tea. It is purported to increase levels of GABA, serotonin, and dopamine in the brain, which can help to reduce stress and anxiety. L-theanine may also promote a sense of calm and improve overall well-being. Some studies have also suggested that it may improve cognitive function, although more research is needed. Most reported drug interactions with theanine are due to its sedative effects.

Hordenine is a naturally occurring alkaloid found in various plants, including barley and cacti. It is structurally related to epinephrine and ephedrine and gets its name from the Hordeum genus of barley, from which it was first isolated. Hordenine has been marketed as a dietary supplement with claims of boosting energy and athletic performance, but there is limited scientific evidence to support these claims. Some studies suggest that it may have properties as a stimulant, but further research is needed to confirm its effects and safety.
