I found this product very good. The fact that it is dissolved in the mouth without having to drink water helps a lot for those who go to the bathroom a lot at night. The value of the product is quite taken into account since q comes with 200 capsules, meaning the person has melatonin for almost a year. I had never bought anything from source naturals. I bought a little suspicious and the product is of excellent quality and very practical to use. As I already mentioned in other posts ... on evitamins delivery by the USPS and very good. The customer can follow the product from the day of purchase until the final delivery of the product.
