This is a sensitive area and is generally not recommended without medical approval. Safety data in children is limited, and growth, hormones, and neurodevelopment differ from adults. Sleep or stress complaints in children may have underlying causes that need clinical evaluation first. Focus on routines, sleep hygiene, and screen habits, and seek pediatric guidance when needed. Supplements should not be treated as a quick fix. If a clinician approves, product choice and dosing must be professionally planned.
