Great product, I would definitely recommend that you start on one a day or take two at night before bed because it helps you sleep better and it could make you groggy during the day if taking in the morning. But I love this product makes me feel happier after the first week ! Would recommend to anyone who wants a natural supplement instead of prescriptions. Also I recieved my two free bottles after my review was summited on Amazon. Just another Awesome perk from buying through dr.emil! Thanks for reading have a great day and I hope this helps someone's questions.
