    • Natural, deep sleep

      from Arizona on 10/21/2022
      We've used kavinace for years for occasional restlessness. During menopause I used it regularly with consistent results of quick, deep REM sleep without after effects. Today, we still use it as needed with the same reliable results. Even when we get up at night, we return to deep sleep quickly. I wish this product weren't so expensive and still escalating in cost, because it's so reliable I always keep Kavinace on hand.

      Pros

      Works fast and consistently

      Cons

      High price that keeps escalating

    • Good, but could be better...

      from STUDIO CITY CA on 3/16/2021
      I have just begun using Kavinace OS, and there's good to report....and bad. First the bad: I find that melatonin in capsule form is less effective than the sublingual form, which enters the bloodstream more quickly. This distinction is important when you want to get to sleep quickly. The good: the Kavinace OS does include some helpful ingredients not often found in a melatonin supplement. If, for example, you have hypothyroidism, you'll welcome the inclusion of zinc and selenium, which have been shown to support thyroid health. But, it's hard to recommend a melatonin supplement that doesn't quickly promote sleep.

      Doesn't work anything like it used too

      from Fort Worth TX on 2/20/2021
      I used the old Kavinace formula before they changed it & it worked like a charm. Tried the new revised Kavinace & it did not work at all.

      Pros

      Can't say anything good about it

      Cons

      Spent so much money on a product that no longer works

      I take 2 teaspoons a night and help my sleep. I like the flavor

      Pros

      I can adjust the amount versus capsules that aren't adjustable.

      Cons

      When first using it, the liquid is a little oily.

      Still works great for sleep for me

      from Arizona on 5/05/2020
      I depend on this for a full night's sleep... and the new formula seems to be working great for me. I miss the old formula, but I'm grateful that the new formula works in a pinch.

      Pros

      keeps me asleep, potent

      New Formula - Bring back old formula

      from Farmington, CT on 1/15/2020
      I have been a long time user of Kavinace. This new formula is not the same as the old formula and no longer works for me. The old version of Kavinace would allow me to gently fall asleep. This new formula does not help me fall asleep or stay asleep. I will discontinue my use of this product. So sad. Please bring back the old formula. Why was it changed to begin with???

      Pros

      Cons

      New formula
