What it is
L-theanine is an amino acid found naturally in tea and available as a supplement. It may influence signalling in the nervous system, but effects vary between people.
This capsule is considered after an online consultation and clinician approval before payment, particularly if you take medicines or have ongoing symptoms.
Why people ask about it
People ask about L-theanine in relation to calm, sleep or focused attention. Study findings are not a guarantee of an individual response.
What the science says
Small human trials have assessed stress, sleep and attention, sometimes alongside caffeine. Results are mixed, and studies vary in design; evidence for consistent or long-term effects is limited.
Is it right for me?
A clinician may consider it for an adult after reviewing medicines and health history. Seek advice during pregnancy or breastfeeding and if you take sedatives or medicines affecting blood pressure.
