Brought it for my 19 year-old daughter for anxiety & to help her focus with work & college work. She works at a high pace vet clinic & is going to school to be a vetinarian. The 1st day she took 2 gummies in the evening & she passed out. Over the next few days I gave her only 1 gummy in which she takes in the afternoon. She now loves it & says that it really calms her down & helps her focus.
