Lemon Balm
Also known as: Melissa officinalis, Melissa Extract
A calming botanical used for stress, relaxation, sleep quality, and occasional digestive discomfort.
What it is
Lemon balm (Melissa officinalis) is a mint-family herb traditionally used for calming, digestion, and sleep. Modern supplement products typically use dried leaf powder or standardized extracts. It is especially popular in stress and sleep formulas because it offers a gentler calming profile than stronger sedative botanicals.
How it works
Lemon balm contains rosmarinic acid and other polyphenols that appear to influence GABA signaling by inhibiting GABA transaminase, the enzyme responsible for breaking down GABA. This may support a calmer nervous system state without heavy sedation. It also contains volatile oils and phenolic compounds that may contribute to digestive comfort and relaxation.
Clinical dose range
300–600 mg standardized extract/day
Most studies use 300–600 mg/day of extract, often standardized to rosmarinic acid. For sleep support, it is commonly taken in the evening, either alone or paired with L-theanine, magnesium, or valerian.

Generally well tolerated. May cause drowsiness when combined with sedatives, alcohol, or sleep medications. People with thyroid disorders or thyroid medication should use caution because lemon balm may influence thyroid-related pathways in some contexts.
