Lemon balm

These are the amounts published trials administered — not a recommendation, and not a dose to copy. Trial participants were screened, supervised and given a characterised preparation. What is in a retail bottle is frequently not what was studied, and the amount that suits one person is not general advice.

• Studied for Acute mood and cognitive testing

  300–1600 mg

  Not enough

  Dried leaf extract, single dose · Single dose, measured over hours

  Acute crossover studies in small groups of healthy volunteers, mostly from one research group. Results were dose-dependent in inconsistent directions.

• Studied for Anxiety, sleep and palpitations

  500–1000 mg

  Not enough

  Standardised extract, daily · 2–8 weeks

  A small number of trials, several from Iranian centres, with subjective endpoints and limited independent replication.

None of the timings below were directly compared in a trial. They reflect how the research happened to dose, or what the pharmacology implies — which is not the same as a timing being better.

• 🌙Evening

  Not enough

  Dosed in the evening when sleep is the outcome; cognitive studies dosed in the morning. Neither compared times.

  Timing was not directly compared. This reflects convention or how the compound behaves in the body, not a trial showing this window works better.
