This supplement should not be overused, but it can be helpful with jet lag, to aid with general sleep issues, assist with migraines and cluster headaches, and during a protocol to improve female egg quality. Also note that taking too high of a dose can actually give you the reverse effect. This brand sells it in lemon flavor and this one in raspberry vanilla. Both products are alcohol-free and made in the USA with no binders, fillers, or artificial additives.
