5-HTP has specific clinical evidence in children for reducing NREM sleep parasomnias (sleep terrors). A controlled clinical trial in 45 children with sleep terrors found that 5-HTP at 2 mg/kg/day at bedtime significantly reduced symptoms versus no treatment, with benefits sustained at 6-month follow-up. It acts as a direct serotonin precursor upstream of melatonin synthesis.

Griffonia simplicifolia seeds are the primary natural plant source of 5-HTP, which has been used in pediatric clinical studies for sleep terrors and NREM parasomnias. 5-HTP derived from Griffonia at 2 mg/kg/day significantly reduced sleep terror frequency in a controlled pediatric trial. Griffonia is the standard botanical source of 5-HTP in sleep supplements.

Iron deficiency is directly linked to pediatric sleep-wake disorders including restless legs syndrome (RLS), periodic limb movement disorder (PLMD), and restless sleep disorder. Clinical evidence from pediatric sleep clinics demonstrates iron supplementation improves sleep in iron-deficient children with these conditions, with 73% of children in one institutional study showing improvement in at least one sleep symptom.

L-Theanine has been studied specifically in children in one randomized, double-blind, placebo-controlled trial. In 98 boys aged 8–12 with ADHD, 400 mg/day for 6 weeks improved actigraphy-measured sleep efficiency and sleep percentage compared with placebo. Evidence in children is limited to this single pediatric trial; adult evidence is more extensive.

L-Tryptophan has clinical evidence for treating pediatric NREM parasomnias. A retrospective analysis of 165 children aged 3–18 with primary parasomnia found 84% of those taking L-tryptophan (mean dose 2400 mg/day) improved versus 47% of untreated controls (p<0.001). It is also used to promote sleep in children where standard hypnotics are considered inappropriate.

Lavender aromatherapy has been studied in children with autism spectrum disorder for sleep improvement. One clinical trial administered 2% lavender oil via aromatherapy (foot and leg massage) to 12 school-aged children with ASD, measuring sleep onset latency, duration, and night awakenings. Lavender is also extensively used in traditional pediatric bedtime routines globally.

Lemon balm (Melissa officinalis), primarily studied in combination with valerian in children, showed improvement in dyssomnia in 80.9% of 918 children under age 12. A 2013 open-label study found an 80% lemon balm extract formulation reduced dyssomnia by 70% and restlessness by 68% after 7 weeks in children. It acts via GABAergic mechanisms by inhibiting GABA transaminase.

Melatonin is the most evidence-backed supplement for children's sleep disorders. Multiple RCTs and systematic reviews demonstrate it reduces sleep-onset latency and increases total sleep time in children with neurodevelopmental disorders, ADHD, autism spectrum disorder, and delayed sleep-wake phase disorder. A 2023 Lancet meta-analysis (9 studies) found melatonin reduced sleep latency by approximately 15 minutes and increased total sleep time by approximately 19 minutes in pediatric populations.

Valerian root, most studied in children in combination with lemon balm, showed improvement in sleep disturbances in 80.9% of 918 children under age 12 in a large observational study, with excellent tolerability and no medication-related adverse events over 4 weeks. A 2014 observational study in 169 primary school children also showed highly significant parent-rated sleep improvements.

Multiple indigenous California peoples documented using California poppy specifically to calm and sedate children. The Ohlone Costanoan Esselen Nation placed flowers under pillows to help put children to sleep; the Cahuilla tribe used root infusions as a sedative for infants. The EMA HMPC and French regulatory authorities (Cahiers de L'Agence No. 3, 1998) explicitly include children in the traditional indications for minor sleep disorders and neurotonic disturbances. No dedicated pediatric clinical trials exist.

Chamomile (Matricaria chamomilla) has an extensive traditional history of use for children's restlessness, colic, irritability, and sleep difficulties. Its mild sedative effects are attributed to apigenin binding to benzodiazepine receptors. Robust pediatric RCTs for sleep outcomes are lacking, but chamomile is consistently recognized as a safe traditional herbal sleep aid for children.

Jujube seeds (Ziziphus jujuba) have been used in East Asian traditional medicine for over 2,000 years to treat insomnia and anxiety. Preclinical studies demonstrate that bioactive compounds spinosin and jujubosides modulate GABA-A and serotonin 5-HT1A receptors, promoting sleep onset. Adult human clinical data support sleep-latency reduction; dedicated pediatric clinical trials are absent.

Magnesium is widely used traditionally to support children's sleep due to its well-established role in GABA receptor activation, melatonin production, and nervous system calming. Direct pediatric RCT evidence for insomnia is limited, but there is evidence it may aid children with restless legs syndrome. Plausible mechanisms are supported by adult clinical trial data showing improvements in sleep quality and efficiency.

Passionflower (Passiflora incarnata) has traditional use for children's anxiety, restlessness, and sleep difficulties, and is frequently included in pediatric herbal sleep formulations. Its calming effects are mediated through GABA-A receptor interactions via chrysin and related flavonoids. Direct pediatric sleep RCT data are limited; evidence is supported by adult trials and traditional application in combination herbal products for children.
