Kavinace is an amino acid approach to brain nutrition supplementation designed to assist with sleep problems, anxiousness, and stress. The description of this supplement states that it can deliver the advertised benefits by supporting optimum GABA levels, the chief inhibitory neurotransmitter. The formula offered by NeuroScience contains a derivative of this naturally occurring neurotransmitter, known as Phenibut, which can easily cross the blood-brain barrier to producing the necessary effects.

Is Kavinace Right For You?

Kavinace is advertised as a powerful amino acid approach to brain nutrition supplementation. This brain supplement is claimed to be effective in promoting restful sleep and in reducing stress and anxiousness by supporting proper GABA levels. The company behind this product is NeuroScience.

According to their official website, this manufacturer is specialized in neurotransmitter clinical research and the development of medical programs for some of the today’s most challenging health conditions. The company’s product portfolio features several claimed “best sellers” such as TravaCor, AdreCor, Calm-PRT, Kavinace, Serene, LoraQuil, and GabaMax.

We were unable to find a dedicated website for the manufacturer, which, in an era where online presence is essential for any business, can be regarded as a shortcoming. Nonetheless, the reputation of this manufacturer and its good practices are a direct consequence of the positive image its many premium formulations hold among consumers.

NeuroScience claims this product is one of their “best calming supplements.” But the official statement goes beyond that and advertises Kavinace as a “uniquely designed to enhance GABAA and GABAB receptor function,” as well as promote healthy GABA levels.

According to the company, this formulation is different from traditional GABA supplementation. However, no arguments are offered to support this claim.


Ingredients of Kavinace

Kavinace includes the following ingredients: Proprietary Blend (Taurine and 4-amino-3-phenylbutyric acid), microcrystalline cellulose, vegetable cellulose, and magnesium stearate.

    Please do not take Kavinace. It is dangerous. My naturopath prescribed it to me three years ago for insomnia. It worked like a charm for me. However, I kept having to increase the dosage to get the same effect. Now I am dependent on four capsules a night, and they don’t even work anymore. I have tried to cut back the dosage twice and both times experienced severe withdrawal symptoms including insomnia, severe muscles tension, racing thoughts and rapid breathing. I have reported this problem to the FDA and they are taking my report very seriously. I have read about others experiencing withdrawal symptoms, but that was after I started having problems myself. I wish I had read up on it before I started taking it but I trusted my naturopath. I even consulted a psychiatrist/sleep specialist MD who said she has heard from others that it is habit forming and can cause withdrawal symptoms.

    This is the only product that worked for me after a stressful 6-mo bout with insomnia in 2015. (Regular Kavinace, not the Ultra PM). I recommend to everyone. At first I took it with a small dose of Seraquil. It was a magic combo for me and I started sleeping through the night again. After two weeks, I dropped the Seraquel. I always keep Kavinace on hand but only take it when I am restless or anxious before bed. I find it takes about 30 minutes to kick in and it is great at keeping you asleep all night!

    I have just started taking Ultra p.m. at the suggestion of my therapist. I am experiencing serious fatigue and nausea the next day since I started taking it a few days ago. Has anyone else had this experience? I love that it has helped me sleep but if this is a side effect, I obviously won’t be able to keep taking it.

      When I tried the Ultra PM, I had the same response and could not take it. When I switched to the plain Kavinace, it worked beautifully with no side effects (unless I take it much too late at night, then I might be drowsy when I first wake up.)

  4. 5

    I give it 5 stars- I take the kavinace ( not the pm) & it has calmed my mind to sleep solid 7 hours. I do not experience any side effects. my naturopath recommended I take 1 capsule before bed. I recommend you see a naturopathic dr. before taking any supplements so the professional can prescribe what is right for your body.

  5. 6

    After one pill and one night, this product is not for me. Nightmares, waking every 30 minutes, sick in the morning, groggy. Zolpidem gives me 4-5 hours of sleep, and I’m learning how to rest/doze for another couple of hours.

  6. 7

    YES–I’m getting increased swelling in my feet after using Kavinace for awhile. I do sleep soundly when taking it however–almost worth the side effect. But I also feel a very slow starter in the morning and some dizziness also. Wondering what to do for sleep if I stop using Kavanase PM however!

      This is very interesting….I’ve had tight ankles and my shoulder problems have increased…what ingredient causes this?

  7. 9

    I just started taking Kavinace PM at the suggestion of my doctor because I have been having great trouble sleeping for the last 6 weeks or so. I find it helps me sleep a lot better through the night but that it also has me napping for 3 hours at a time during the day and feeling a bit groggy. Can anyone else speak to this problem? Is there something I can eat or take to reverse its apparent effect which continues for me during the day?

  8. 11

    Kavinace was recommended to me by my acupuncturist to deal with chronic pain and the anxiety associated. It can cut the pain cycle if I am having a flair up and has allowed me to function again. I don’t take it for sleep issues but I do seem to get better rest. It has drastically improved the quality of my daily life with no side affects.
    I had previously tried Travacor and had an adverse reaction with increased pain in all areas of my body. I’m very happy with the results I’ve had with Kavinace in contrast.

    I have used Kavinace PM and find it very helpful for my sleep. I have requested an order through
    Mary’s Hope New Beginnings program and am waiting for the order.

  10. 13

    I love this product! It works great whenever I’m feeling super anxious before bedtime. It takes about 30-45 minutes to feel the full effect but it sure does work! The only downside is I can’t take it consistently more than 2 days in a row; otherwise, it doesn’t have the same full effect. It works best only when you really need it.

  11. 14

    I LOVE this product! I have used it for years and have had no side effects. I have shared it with my friends and people that have had insomnia for years started sleeping.

  12. 15



    It worked at the beginning and I felt a bit drowsy upon awakening. Over time, its effectiveness has diminished. I have used it in combination with Remeron. I usually sleep 4-5 hours a night. I have heard some types of cannabis is helpful for sleep but I have not yet tried it.

    I tried Kavanace Ultra PM and am having hallucinations. Is any one else having these problems?

  14. 17

    I definately felt the effects of taking kavinace. It hepled me relax and I was able to fall asleep. I went into a deep sleep and was able to enjoy my rest. I woke up feeling like I could sleep longer.

  15. 18

    I have had awful memory issues since taking Kaviance PM. It has helped me sleep which is great but I am going to have to wean myself off of it. Especially since hearing other people also are having memory issues.

  16. 19

    I have taken Kavinase PM for about 4 months. It helps me stay asleep for at least 4-5 hours which is much better than I normally get. I have had leg cramping in my calves since taking it and now have swollen feet and ankles. Anyone else out there experienced this?

    I have been taking Lunesta for probably10 years. It is either that or don’t sleep at all. About 5 years ago, I started only sleeping 3 to 4 hours a night with the Lunesta. When I added the Kavinace Ultra PM, I started sleeping 6 to 7 hours, which makes a huge difference in how I feel the next day. I am now having a huge memory problem that I am sure is due to so many years with little sleep and with so much use of the Lunesta and Kavinace. But I have chosen sleep over the side effects of the supplement and drug.
    If I use just the Kavinace, I don’t fall asleep.

    The review states NeuroScience as a company does not have a web site – you may want to go to NeuroRelief dot com – you will see that they actually do. Since there is no date the review – which is an issue from my perspective as I don’t know how recent the information is – the web site may not have existed at the time of the review.

    This product has worked for me for the past week. I have not slept this well and stayed asleep through the night in a while.

    I have taken Kavinace and Xanax….at same
    time. Since I am under greater stress, is it
    safe to increase the Kavinace?

    Lorraine Brammer


    I love this product. I was given this by a holistic doctor. It works wonders for me. When I go to bed is when I start thinking of the day and can’t sleep. If I take this 30 minutes before I go to bed, I get a good night sleep with no hangover the next morning compared to over the counter sleep aids. I do not take it every night, but just when I feel I need it.

    I am 59 yrs old and a life-long insomniac. I am not a stressful person, quite the opposite content, happy, and optimistic. Just could not go to sleep,nor stay asleep. Prescription sleep pills work opposite and I have tried every natural homeopathic remedy without success. A month ago, my Dr gave me Kavinace Ultra PM – and I have slept soundly almost every night. Amazing stuff. Sleep definitely makes a difference in your overall health.

    • 25

      Ruth, Did the product work right away? I have problems falling and staying asleep. Prescription medications have not worked on me. I tried Kavinace 3 times, of which only once it worked, and the other two did not, as a matter of fact, it kept me awake all night. I am wondering if I should give it a chance again?

      • 26

        Ruth Mills


        It did work right away – for a couple of days and then it did not work for a day or two – I am thinking because I ate a big late dinner. But I kept using it and it now works no matter what. I think there is also a difference between the reg and the ultra pm which I take.

    I’ve read a lot about amino-acids and how they can restore neurotransmitter levels in the brain in order to create balance and support normal brain function. I have been fighting depression my whole adult life and tried various approaches to fight against it. Kavinace is one of the drugs that work, but after a while it becomes ineffective. I have to disrupt treatment for a few weeks, and then it works better. Still, I like the product because it is generally effective well and helps me keep my condition under control.

  23. 28

    Does anyone else get weird and vivid dreams? It has helped me sleep but after reading a lot of these comments, I think I will discontinue using it.

      Bruce Ogletree


      My sleep specialist recommended I use Kavinace along with Trazadone (1-2 tablets of each at bedtime) to alleviate my insomnia and it works very well. I have not noticed any side effects.

    • 32

      I too am wondering if Kavinace can be taken w/ Klonopin- the manufacturer didnt know & my doctor has never heard of Kavinace. I don’t want an opposite reaction to happen

  24. 34

    I have taken Kavinace and Kavinace Ultra PM for years now and have had a phenomenal experience with both. I don’t feel any side affects. They have helped me sleep and reduced my anxiety dramatically (along with other supplements). Obviously Kavinace affects people differently, so it is on a case-by-case basis. I haven’t had any dependency on Kavinace either. Sometimes I will run out of supplements, not take them for a few weeks, and I never have any problems.

    • 35

      I started taking Ultra a year ago. I take one every night. I sleep 6 Hours No hangover no leg cramps no weird dreams. I have gone a month at a time without it and do not have a dependency other than I would rather take it cause my busy mind can be calm and quiet n I can sleep. Not sure about the gaba interfering with the brain making its own ?

    I have stress cardiomyopia (broken heart syndrome and panic attacks. If I take the daytime Kabinace it lessens the intensity of the panic attacks, But I am grogged and sleepy all day. I took one nightime one and dell and hit my head trying to go to the tile bathroom 1t 3:00 a.m. I don’t take the nightime one since that incident. But my natural health specialist wants me to continue the daytime 4 x day. But I am week and sleepy all day. What is in the daytime one that makes me so limp and wasted all day? The only good thing is that it makes the Panic
    Attacks less intense. Any suggestions?

    • 37

      I would suggest adding Yoga for relaxation to your evening routine 45-60 minutes before bedtime. No computers, no TV, no bright lights, just relaxation. This helps calm the brain and rebalance the energy throughout the body. I also use Kavinace PM Ultra only as needed and have very good results and a restful nights sleep. Find gratitude in the simple things in life-every day. It makes a big difference. Best wishes!

    • 38

      Try ashwaganda root. I have some by –good gosh having a hard time remembering after taking Kavinace Ultra p.m.!!–supreme nutrition is great.

  26. 39



    I was prescribed Kavinace by a Naturopathic physician. It was prescribed primarily as a sleeping aid, secondly to assist in my valium taper. It worked beautifully for both situations. The first time I took it, it helped immediately. More recently, I found I needed some time for it to build up in my system before it became effective – but it did. Great product.

      Joseph Losi


      I think that depends on how long you’ve been taking Xanax and at what dosage. You wean off Xanax should be carefully monitored by a ARNP or a Psych MD. As you likely know too steep a taper can produce very challenging side affects.

    I discovered Kavinace a few years back. It worked for me, I managed to get rid of the anxiety which was torturing me since I was an adolescent. I didn’t experience any of the side effects mentioned by other users. Maybe I’m lucky in that way. But the medication works!

  28. 44

    I take Kavinace after doing the pendulum test to see if I need it that time. put your left hand over the solar plexus add the right, then while standing breathe deep 2-3 times, if you sway forward its good for you at that time, if you sway backwards, not for you at that time. donna eden energy medicine technique

    I’ve been using Kavinace to fall asleep for at least 5 years now. (hubby snores) I can fall asleep and stay asleep most of the time unless something is really really bothering me. So now I only take one. Love this stuff. I can fall asleep in less than 10 minutes, sleep through the night and feel fine in the morning. I just take the regular one, not the PM. My son just started taking it during the day if he’s stressed and it helps a lot with mood and anxiety. It wouldn’t let me, so I am telling you it should be rated with 5 STARS!!

  30. 47

    I have always had sleep issues, Nothing over the counter worked so i took Ambien. My niece talk me about Kavinace. It works great for me!!!

  31. 48

    I have only been taking this product for abt a week or two . I’m taking it at bedtime as well as also taking Calm G twice a day. I have gained about 4 pounds in a week. Does this cause weight gain? I am sleeping better and feel better during the day. But…. Have worked to lose some weight in the recent past and do not want to gain it back.

    Kavinace was an effective treatment for my son’s anxiety problems which appeared in high-school. We tried other treatments before it, but since none of it seemed to be effective, the doctor recommended this one. In a couple of weeks my son was feeling better, he was coping much better with its disease, had fewer and lower intensity symptoms. Combined with therapy, we were able to make him feel more confident and after a year or so terminated the treatment as he was feeling much better. Kavinace help my son become himself again: a happy, fun person who enjoys living!

    I tried the Kavinace PM several times. It didn’t work well for me. It made me relaxed but didn’t make me tired enough to fall asleep. The next day I was an absolute wreck! Groggy, dizzy and nauseated. I don’t really know which ingredient made me feel so lousy but I did give these supplements an honest try. I took them at least four times with the same side effects. Sorry it didn’t work cause I’m still sleepless in Clearwater.

    • 52

      I had the exact reaction. Slept fitfully and then experienced extreme drowsiness, stomach upset and felt DRUGGED!! I will resort back to a 1/4 Zanax.

      • 53

        I had the same reaction along with horrible muscle tension. My holistic dr recommended it and it’s horrible. I had to leave work the second day I took it because I couldn’t think. It’s not worth the money or dangerous side effects.

  34. 55

    I have been taking Kavinace PM for a little over a year. It was recommended by a high priced “naturopath” who reassured me she has never seen anyone have any problems with it. I began with one, but then needed two, then needed three. When I realized I was going to need a 4th to sleep through the night, I stopped taking it. HORRIBLE. For the last two weeks I can’t sleep, and I’m feeling severe muscle tension and depression. Come to think of it, the whole time I took it I was having some serious gastrointestinal symptoms including acidity and diarrhea. Finally I returned to taking just one, but am still having pretty serious symptoms. I do not recommend this drug. We just don’t know that much about it.

  35. 56

    I initially got this from a naturopath MD for chronic insomnia. I had taken ambien for over 10 years on a nightly basis and that was all that helped me sleep. Now the family practitioner refuses to prescribe ambien anymore because of new FDA warnings. So I started taking two Kavinace at bed time and I am sleeping better than with Ambien. My big question is ordering this at various online vendors. Is it the same quality as what the doctors get from NeuroScience’s order site at Neurorelief.com? I no longer can see the naturopath and have no other way to get the Kavinace and they are truly the best sleep aid in the world for me.

  36. 57

    My NP had me try Kavinace to help get more deeper sleep and help with stress and anxiety. I was taking two pills at dinner time and noticed if I took it later in the evening or without food, I was so sleepy the next day. She lowered me to one pill and I take with food at 5 pm and I notice a huge difference when I sleep. So far….so good.

  37. 58

    I was on cymbalta to help with nerve pain, and when I got off of it, I couldn’t sleep well after that. I tried everything and finally someone told me about Kavinace PM. It works like a charm. I sort of have a hard time getting up in the morning, but it’s not too bad. I would rather feel well rested and a little groggy than not rested at all, which was miserable. I’m trying to figure out what to do from here because I would like to get pregnant again and want to stop taking it. I typically take one pill a night, but every now and again I don’t need it. Any suggestions for getting off of it and being able to sleep? Ha!

    I sleep like a log for about 9-10 hours and I wake up sluggish so two weeks ago I put my alarm clock for 7 am and I exercised feeling energized after that and then I took 1 cup of coffee . Because I am anxious a doctor recommended me to take Kavinace and after seeing your comments I believe if I take it I would sleep all day and all night, so I am not going to take it because I don’t need to sleep more.
    So, I am going to continue controlling my sleep, 7 hours is just fine for me and I am energized and less anxious during the day. Sleeping like I was doing for 9-10 hours is debilitating to the brain and the body.
    thanks for listening.

  39. 61

    Thank you so much for your posting on the addictive properties of Kavinace. Starting about six months ago, I took Kavince (one pill) for sleep disturbance and more recently took Kavinace ultra pm for same as it has melatonin and 5 htp in it, which I was taking anyway. All in one, great huh? Well, not so great as only recently have begun to experience queasy feelings in the afternoon, even after a good night’s sleep. Very difficult to describe but just not like myself. I am normally a high energy person and I felt lethargic, strange, etc. I stopped taking Kavinace three days ago and am experiencing what I can only describe as “withdrawal.” Back to the melatonin and 5 htp, old amino acid friends, sleeping even better now.

    NeuroScience company does have a web site – neurorelief.com
    I don’t work for them nor do I wish to promote them; just providing information missing from your article. No need to post my review. But I am happy with how Kavinace works for me.

  42. 65



    I started taking Kavinace a few months ago, on and off every week to help get through the night after a pelvic fracture. It helped me sleep very deeply, both at night and during long daytime naps. I’ve actually never been able to nap so well. But recently (I’ve taken it twice in two weeks) if I take one Kavinace and don’t fall asleep right away, I start to feel like I can’t breathe. My body is trying to relax into a deeper state and sometimes I even feel a strange “thump” like an arrhythmia, and then my breathing is just heavy and slow. Eventually I fall asleep and have a wonderful, deep night’s rest, but the period before falling asleep is alarming and I don’t think I’ll take it again since it seems to be disturbing my heart and breathing rhythms. Anyone else have this?

    • 66

      From what I’ve read about the main ingredient, “Phenibut” it is the cause of those symptoms you are having. I started having similar effects — like I couldn’t catch my breath (even as I was trying to fall asleep), and also the irregular heartbeats. That’s when I researched this product that I had been told is safe and learned that people can develop a dependency on it and that the withdrawal effects can be terrible (and maybe even dangerous, if you try to stop cold-turkey).

  43. 67

    Barbara Adams


    Kavinace made me sleep like a baby, BUT I felt drunk and unable to focus during the day. I took it for three nights and the fourth night I took it and could not sleep at all. I had the usual racing thoughts. I stopped taking Kavinace and it took me a week to feel normal and focused again.

  44. 68

    I’ve struggled with sleep issues my entire life. Recently diagnosed with RLS, PLMD’s and sleep apnea. Was on medication to calm the RLS and PLMD’s which was then exaggerated by the CPAP. On the suggestion of a local homeopathic pharmacy I tried the Kavinace PM supplement and not only did it help me sleep, it reduced my glucose levels which were all out of whack because of my sleep issues, it also helped the RLS. I am no longer taking the prescription meds for the RLS. I am grateful for stumbling onto the Kavinace PM. It may not work for everyone, but again everyone’s sleep issues are not the same.

  45. 69

    This works. I have anxiety and panic disorder, and all the typical symptoms (irritability etc) and just one pill can significantly reduce my symptoms. Phenibut is real, is a prescription drug in russia, and works well. However, one can be dependent on it, and you shouldn’t take it for extended periods of time.

  46. 70

    I use Kavinace as prescribed by my doctor. I am dealing with peri-menopause and battling with related symptoms including shaking and insomnia. I get wonderful results. It reduces my shaking, calms my brain and helps me sleep. I highly recommend it and love that it’s not a drug.

    • 71

      Kavinace IS a drug! Google “Phenibut” (the main ingredient) and “withdrawal” or “addiction.” I have been taking it five months at my naturopath’s recommendation and developed a tolerance to it and had to increase my dose. Now I am facing withdrawal symptoms to quit taking it. From what I’m reading, it’s not safe to stop cold turkey. It is similar to Benzos from what I’m reading. It is only for occasional use, but most of us were/are taking it every night. I’m very concerned that info about the addictive nature of this supplement is not offered more freely by its manufacturer. If I’m reading the info about its addictiveness incorrectly, feel free to let me know.

  47. 72



    I have been taking it as recommended but I feel out of it. I have just started taking it….does that have something to do with it? Maybe I should only take one pill a day and not two? Any advice?

    some random bob


    Got sick once and couldn’t sleep very well ever since. I kept waking every hour or so every night so my doctor had me try kavinace ultra pm and it works so well.

  49. 74

    Excellent!, I believe all things do not have the same effect for all people. I was never a user of drugs except tylenol or aspirin for an occasional headache. I began taking phentermine for weight loss, Kavinace tkes me down from the phentermine “speed” high and I sleep like a baby. I found out the way to clear phentermine from the body is to use caffeine or amino acids. This works.

    I have suffered from insomnia related to Fibromyalgia for years. My physician had me try Kavinace Ultra Pm. It is amazing. I have tried everything out there .
    I have been taking it for over a year now and it is a Godsend.
    I feel calm and well rested when I wake up.completely natural and no side effects. Should invest money in this company.

  51. 76

    My doctor recommended this drug after I suffered a depression a few months ago. I believe it fastened the recovery process and made me get back on track again. I felt a little drowsy some days, but it was manageable, and after I finished the treatment I felt much better.

    I didn’t like this medication because it gave me stomach pain and nightmares. During the day I was calmer but in the night I had trouble falling asleep or the quality f sleep was very bad (because of the nightmare). After switching the treatment, the symptoms disappeared…

      Hi Douglas –
      I am also having nightmares with Kavinace, as well as interrupted sleep. What did you switch to? Thanks – Katherine Duff

    I have been using it for about a year. I sometimes take it to get a good, restful night sleep, and it always works. It is also great for panic disorder and anxiety. I have my children take it when they feel anxious or just have trouble sleeping. It’s a great product, we don’t take it everyday, but maybe once or twice a week. I highly recommend it.

  54. 81

    I’ve been struggling with insomnia that has gotten progressively worse over the years. I tried so many natural supplements that didn’t work that I finally went on Trazadone which really helped me sleep, but gave me horrible dreams and then headaches after taking it for a few months. I’ve been using this for a couple of weeks and so far, aside from one night, I’m sleeping great. I hope this keeps up. I would definitely recommend trying it.

  55. 82

    I have been taking Kavinace Ultra PM for over a year. The first time I took it was on vacation and slept for over 10 hours without waking up and that was in a hotel. I have not had a good nights rest in a very long time. It works really well for me. I wake up feeling really refreshed and well rested. I hate the price but make some sacrifices to purchase it.

  56. 83

    Hey I’ve been taking this stuff for like two years I have horrible insomnia and I’m 15 is that safe. I take two a night and can’t sleep with out it. My doctor recommended it to me but I don’t know lately I’ve just been worried about its long term effects.

  57. 85

    I’m 15 years old, and I have major depression and anxiety disorder. Whenever I get into a panic attack I take a kavinace and although it may take a minute, it works wonders. It calms me down, gets me back to normal, and I usually have a better night’s sleep.

    Kavinace is one of the five supplements that my parents insisted I should take during the school year. Little do they know it was the only one I took. Partly because I though taking five different pills is insane, but also because I felt Kavinace was good enough for me. I had a perfect year with no incidents.

    The lack of sleeping is becoming an issue lately, because it really affects my performance at work and also my nerves. Kavinace has helped me with the sleeping problem and also the other unwanted effects has all go away. Thanks!

    This is a great formula for sleep. I sleep like a baby and I feel more energized during the day and ready to face whatever comes along. My levels of anxiety decreased and I feel calmer and happier.

    As a sleep aid it is one of the most effective supplements near this price point. I have tried many other and I can say for sure that you can find none better. It also has other good effects like making yo more relaxed during the day.

    I used to have trouble sleeping every night. When I got into be I was unable to keep my eyes closed and I would twist and turn for a few hours before I could fall asleep. Kavinace has changed that a lot and now I fall asleep in less than half an hour.

  63. 91

    I have fought anxiety for more than a year before taking Kavinace. I have jumped from prescription drugs to natural remedies and back and forth a couple of times because of side effects and lack of effectiveness. Kavinace however did it for me. I am well enough to deal with anxiety myself and I don’t feel like a walking corpse either. Marvelous.

    I started getting anxious when I started to hold presentations during college. Back then I used to take very potent drugs to calm me down but that turned me into a zombie. Nowadays I take Kavinace when I need to relieve anxiety and I don’t have to worry about any side effects.

  65. 93

    I don’t take supplements, but my sister recommended this to me and it’s been quite a good month for me. I don’t know if I’ll continue because the price is pretty high, but It’s an ok product and you may consider giving it a try.

  66. 94

    Damn this is expensive. I’m lucky my parents got if for me. The product itself is very potent and has a very fast onset when compared to other similar products. I used it successfully every single time and I recommend it if you can take the cost.

  67. 95

    My colleagues basically force fed my Kavinace because I was always shouting at them randomly over the most trivial stuff. I didn’t think it will work but I did not want to argue with them any more. In the end, I calmed enough for them to be satisfied, although I wish It was a little more potent.

  68. 96

    Sleeping aids have been for me kind of a “love it or hate it” affair. Despite similar ingredients and concentrations, some have provided adequate relief, some had no effects. Kavinace not only does work exactly as it should, it also maintains its effects over a long period of time. So far it;s the best I’ve tried and I see no reason for trying something else.

      I have been taking one in am and one in pm and feel very stable and level and the mega-stress I’ve been experiencing is certainly under control, BUT I have noticed a decline in my memory – like it’s sluggish and slow. I’m thinking perhaps the relaxing the pill does to me is also relaxing the memory part of my brain?? Has anyone else experienced this over time? I’m not on much other suppliments and no meds so I can honestly attribute the memory loss to this at least in my way of thinking.. Also, I have had stomach upset in the night come to think of it..

    It’s quite good at relieving anxiety and it also helps me sleep. It’s an ok product, i recommend it.

    With Kavinace, I get a restful night’s sleep which allows me to better focus on my work during the day. I only take the pills in the evening because they make me drowsy.

  71. 101

    I ordered Kavinace because I was tired of the side effects of other drugs, stomach upsets, dry mouth… I don’t think it’s as potent as other pills I have tried, but I intend to keep taking it nonetheless.

  72. 102

    I use this after a super stressful day and when I know I’m going to have trouble sleeping. I take 1 tablet on an empty stomach 20 to 30 minutes before going to bed and I sleep great without any side effects. I don’t have chronic sleep problems or tons of anxiety so for me, this works as a good supplement when things get crazy.

  73. 105



    This helped me to get extra sleep once I started to take it each day. You need to wait a week for it to kick in but after that you should get the same results as me.

  74. 106

    I wish I had read the review above before I order this from the internet. I think I would have thought twice about getting it. I like the review you posted and it makes sense to me. I will read more of what you recommend and see what best fits my needs.

  75. 108

    I am a real nervous persona and always needed to have something to calm me. I am thru with the doctors drugs so I hope this helps.

  76. 110

    I go this supplement since it said it would promote sleep and reduce anxiousness. This is what I really want but I want left with these things. I think I wasted my money on this one.

  77. 112

    Yes, I have noticed the stomach acid after taking it too. It’s not all the time, but sometimes. I have been taking it for years and am worried that I am dependant on it. It looses its effectiveness after about 3 weeks. I take a break for a few nights; either I don’t sleep well or I take an Ambian for a couple of nights then go back to kavinace pm. I wish I could sleep unaided.

    Rae, I am in my seventies and had not been able to sleep all night since my early to mid fifties thanks to menopause. This went on for almost twenty years until I found out about Kavinace Ultra PM. I’ve been on it now for a little over two years and during that time I’ve had to get off of it for short periods in order to get it to work again. The first time I went off for a full month and of course I didn’t get much sleep and was miserable. Later, I found out I could get off of it for two weeks and it was like new all over again although the grogginess wasn’t as bad. I, too, have noticed some stomach acid but didn’t attribute it to the Kavinace until it was mentioned on this website. So now I’ll just have some yogurt before bedtime. I suffer from reflux from time to time and this has been my solution which works for me. Kavinace is a blessing for me but I’ve found that it doesn’t work for everyone and works differently for those for whom it does work. I would just like to know how long I can take it without any problems/side effects.
