This has been an amazing product to add to my children's daily regimen! After using it a week, my autistic son was sleeping through the night 5 out of 7 nights a week instead of the reverse! When we stopped using it a couple months later when i furor to reorder, within 2 weeks, he was waking up 5 to 6 nights of every week again! So I ordered again quickly and returned to our 4 gummy a day protocol and have extra on hand!
