This product provides a very substantial 20 mg of melatonin in a tablet form, characterized by its incredibly low price per serving. With a high review count, it has a strong market presence, likely appealing to those looking for maximum potency at minimal cost. While the value is undeniable for the amount of melatonin provided, the 20 mg dosage is significantly higher than typically recommended for general sleep maintenance and can be overwhelming for many individuals. It is best suited for specific situations like severe insomnia, certain neurological conditions, or for those under medical supervision, rather than as a casual sleep aid.
