Product labels list melatonin in a range of per‑serving doses: low doses (about 1 mg) commonly in children's gummies and liquid, mid-range doses (around 5 mg) in some gummies, and higher adult servings (for example, 10 mg per serving) in some adult gummies.
Common features include adhesive nasal strips that mechanically open the nasal passages to reduce snoring and improve airflow, and lip/mouth tape that encourages nasal breathing by keeping the mouth closed, which can reduce mouth breathing and dry mouth.
