L-theanine, an amino acid primarily found in green tea, has garnered attention for its potential role in supporting individuals with coffee or caffeine addiction. The scientific rationale centers on L-theanine’s ability to promote relaxation without sedation and to modulate neurotransmitters such as dopamine, serotonin, and GABA. Several small-scale human studies and animal experiments suggest that L-theanine can attenuate some of the stimulating effects of caffeine, such as jitteriness and anxiety, while maintaining cognitive performance. This synergistic effect is why L-theanine is often combined with caffeine in nootropic formulations to reduce side effects associated with caffeine use.

However, direct evidence for L-theanine as a treatment specifically for coffee or caffeine addiction is limited. Most studies examine its effects on mood, anxiety, and cognitive function, rather than withdrawal symptoms or dependence per se. Some research indicates that L-theanine may help reduce stress and improve sleep, both of which could indirectly support individuals attempting to reduce caffeine intake. Nevertheless, there are currently no robust clinical trials demonstrating that L-theanine alone facilitates caffeine withdrawal or reduces cravings.

In summary, while L-theanine is scientifically validated for reducing some negative effects of caffeine and for promoting relaxation, evidence for its use specifically in treating or supporting recovery from caffeine addiction is weak and mostly indirect. More targeted research is needed to firmly establish its efficacy in this context.
