      Good ingredients--iffy effectiveness

      from STUDIO CITY CA on 6/06/2022
      I have chronic insomnia, so I always have sleep aids on hand. I did not experience much drowsiness with NeuroScience Kavinace OS. For me, melatonin in the form of a lozenge that dissolves is much more effective. I like the inclusion of l-theanine and resveratrol--made me feel better overall about taking it--just didn't make me sleepy.

      great pills

      from usa on 5/26/2022
      I had use this for a long time and they do work pretty good. But it can take it's time but on the plus side the pills are not too big. The price can be better though


      easy to swallow

      Not Bad

      from NJ on 3/02/2022
      Not bad. I take this from time to time, but always end up going back to Melatonin by itself.

      Does not help me. Is there any hope of ever getting the Ultra PM formula again?




      No help at all

    • Kept me awake

      from MO on 3/30/2021
      I received a package of this supplement with a recent Pure Formula order. Both my husband and I decided to give it a try last night. We each only took 1 capsule, instead of the 2 capsule dosage indicated on the package. This sleep aid actually gave me insomnia. I was up several times throughout the night for long durations, from 3am - 5am. In desperation I took my normal melatonin only supplement just to get back to sleep and through the night. It wasn't just a bad reaction for me, my husband (who normally sleeps pretty good) was also up several times throughout the night and had a miserable sleep. There is something wrong with this product and would not recommend it. I will be tossing the rest of them.




      Did opposite of what it was supposed to do, caused insomnia versus a restful sleep
