  • Sleeping help

    I started taking these to help me stay asleep at night and I’ve noticed that my sleep score has improved significantly since using them. I take three about an hour before bed.

  • Early results

    I’m only a couple/few weeks into starting, but I have noticed a deeper sleep…not at the 5 or 6 hour range I’m hoping to get to, but definitely 3 to 4 hours. Which is better than I was doing.

  • Good product

    This is really helping with my sleep quality. Along with routine, no screens and no food couple of hours before bed I’m getting the best quality sleep I’ve had in a long time.
