Pharmacology

Theanine is structurally similar to the excitatory neurotransmitter glutamate, and in accordance, binds to glutamate receptors, though with much lower affinity in comparison. Specifically, it binds to ionotropic glutamate receptors including the AMPA and kainate receptors and, to a lesser extent, the NMDA receptor. It acts as an antagonist of the former two sites and as an agonist of the latter site. In addition, it inhibits glutamine transporters and glutamate transporters, and thus acts as reuptake inhibitor of glutamine and glutamate.

Theanine increases dopamine, GABA, and glycine levels in various areas of the brain. It also effects serotonin in a manner which is still a matter of debate in the scientific community, with separate studies showing increases and decreases in brain serotonin levels using similar experimental protocols.

These various changes in neurotransmitter levels contribute to the calming and nootropic properties of theanine.

Subjective effects

The effects listed below are based upon the subjective effect index and personal experiences of PsychonautWiki contributors. The listed effects will rarely (if ever) occur all at once, but heavier dosages will increase the chances and are more likely to induce a full range of effects.

Physical effects

• Sedation and Stimulation - Theanine is mildly stimulating at light to common dosages but becomes sedating with strong dosages at around 300mg.
• Muscle relaxation - at heavy doses, theanine induces muscle relaxation comparable to that of benzodiazepines.
• Spontaneous tactile sensations - Theanine produces a physical feeling of glowing warmth that is present across the entirety of ones body. This occurs at dosages around 300mg.

Cognitive effects

• Anxiety suppression - Theanine produces anxiolytic effects which are comparable to a mild dose of a benzodiazepine but without the accompanying disinhibition.
• Mindfulness - Theanine induces distinctive states of mindfulness more consistently than perhaps any other known psychoactive compound.
• Memory enhancement - Theanine has been shown to improve memory and attention in subjects with mild cognitive impairments.
• Thought deceleration
• Thought organization
• Perception of increased weight
• Analysis enhancement
• Focus enhancement
• Motivation enhancement

Toxicity and harm potential

Theanine is non-addictive, is not known to cause brain damage, and has an extremely low toxicity relative to dose. Similar to many other nootropics drugs, there are relatively few physical side effects associated with acute theanine exposure. Various studies have shown that in reasonable doses in a careful context, it presents no negative cognitive, psychiatric or toxic physical consequences of any sort.

It is strongly recommended that one use harm reduction practices when using this drug.

Tolerance and addiction potential

Theanine is not habit-forming and the desire to use it can actually decrease with use. It is most often self-regulating.

Tolerance to the effects of theanine are built after prolonged and repeated usage. After that, it takes about 7 days for the tolerance to be reduced to half and 14 days to be back at baseline (in the absence of further consumption). Theanine presents cross-tolerance with no other known compounds, meaning that after the consumption of theanine all other psychoactive compounds will not have a reduced effect.
