melissa officinalis leaf extract + lactuca sativa herb juice + magnesium dicitrate + l-tryptophan

This is a **combination dietary supplement** composed of **Melissa officinalis leaf extract** (commonly known as lemon balm), **Lactuca sativa herb juice** (garden lettuce), **magnesium dicitrate**, and **L-tryptophan**. - **Melissa officinalis leaf extract** is widely used for its proposed calming, anxiolytic, mild antidepressant, neuroprotective, antispasmodic, digestive, antioxidant, antiviral, and sleep-supportive properties[1][2][3][4]. It contains bioactive compounds (notably rosmarinic acid and flavonoids) that may modulate neurotransmission, including GABAergic mechanisms, contributing to anxiolytic and sedative effects. - **Lactuca sativa herb juice** is traditionally associated with mild sedative and calming effects, sometimes used for nervousness and sleep aid, likely via mild CNS depressant actions (mechanistic evidence limited). - **Magnesium dicitrate** supplies bioavailable magnesium, a mineral important for nervous system balance, sleep regulation, and muscle function; magnesium participates in NMDA receptor modulation and may have a calming effect. - **L-tryptophan** is an essential amino acid that serves as a precursor for serotonin synthesis, playing a role in mood stabilization and sleep induction. The combination is marketed principally for **stress relief, mild anxiety, sleep support, and mood stabilization**. No robust clinical evidence exists for the unique effect of this specific 4-ingredient combination.
