What is Kavinace OS?

Kavinace OS is a new sleep supplement by NeuroScience. It was created as a result of the original (and widely popular) Kavinace line being discontinued in April of 2019. It provides a comprehensive blend of ingredients shown to improve the onset, duration, and efficiency of sleep.

What is in Kavinace OS?

The ingredients in Kavinace OS include:

  • Magnesium
  • Zinc
  • Selenium
  • Melatonin
  • L-theanine
  • Resveratrol
  • Astaxanthin

Is Kavinace OS better suited for someone previously taking Kavinace or Kavinace Ultra PM?

Kavinace OS is more geared toward someone who was using Kavinace Ultra PM in the past. This does not mean that someone who was taking the original Kavinace will not benefit from Kavinace OS, but the Kavinace OS contains 5 mg of melatonin versus 3 mg in the Kavinace Ultra PM and zero melatonin in the regular Kavinace. Both Kavinace OS and Kavinace Ultra PM are only recommended before bed, whereas some people did report taking the regular Kavinace during the day to help aid with stress/anxiety. For those who took the regular Kavinace during the day or for those who would prefer a product without melatonin, we would recommend trying Calm CP or TravaCor.

What does the “OS” stand for?

The “OS” in Kavinace OS stands for oxidative stress.


 Kavinace OS Sleep Study

Proven ingredients, improved sleep quality

Randomized, double-blind, placebo-controlled studies have shown that:

  • Supplementation with astaxanthin and zinc significantly improved the onset of sleep (figure above)
  • Supplementation with melatonin (5 mg), magnesium (225 mg), and zinc (11.25 mg), significantly improved the onset, duration, and efficiency of sleep

Kavinace OS contains these researched ingredients shown to improve sleep quality

I take this 30 minutes prior to bedtime and begin to relax. For me, this works as well or better than Kavinace PM.

Helps me fall asleep when I wake up

Review by Linda (Posted on 11/6/19)

Overall Rating

I take 2 a night. I fall asleep more quickly and when I wake up I can usually fall back to sleep. So glad Kavinace is back even though it is not quite as good as the PM was. Kavinace PM was a little better for me but the new Kavinace is better than nothing.

Doesn’t compare for me

After Kavinace Ultra PM was discontinued, I gave kavinace OS a chance and unfortunately, got poor results. I miss my sleep and the old kavinace.

Works really well for me!

Review by Janet (Posted on 10/8/19)

I've tried a lot of natural sleep aids, and Kavinace OS is my favorite so far. I used to love Kavinace, and was sad when they discontinued it. However, the OS version works much better for me. About 30 mins after taking it, I feel calm and sleepy, and have been able to fall asleep easily and sleep through the night (unless my kid wakes me up, but that's a different story). Definitely worth a try!

Miss the original

I used to be a regular KUPM user and have tried the OS but I have to take two as opposed to only one PM. I also wake up mid sleep cycle. I've also tried Alpha Gaba PM which I actually like better than OS but still wish they would bring back the PM.

Great Replacement

Review by Charles (Posted on 9/25/19)

Overall Rating

I have previously taken Kavinace Ultra PM for sleep. When I was without it, after it was discontinued (and before the OS was released), I had very restless sleep. Now that I have begun my new regimen, I sleep completely through the night without waking up. In the past, I have taken both Kavinace and the Ultra PM. I actually prefer the Kavinace OS capsules.

Still Reigns Supreme

Review by Kim (Posted on 9/25/19)

Overall Rating

I have tried several different over the counter sleep aids and find Kavinace to reign supreme compared to all of the others. I am not one to use prescription sleep aids due to the dangers and many side effects associated with them, including habit formation. I was skeptical about the new Kavinace OS, but find it to be pretty similar to the Kavinace PM. I was very disappointed when the ultra pm was taken off the market. Thank goodness they brought it back under a new formula and name. I have to be perfectly honest, the Ultra PM smelled and tasted a lot better, but they both are very effective and that seems to be the only real difference that I noticed.

Not for me

It just didn't work for me. I was up most of the night. The PM was better for me. It's just an individual thing.

Amazing sleep!

Review by Nicole (Posted on 9/25/19)

My husband and I sleep extremely well when we take Kavinace OS. I think our friends and family are tired of listening to us talk about what a difference it makes in the quality of our sleep! We recommend it to anyone who complains of lack of sleep, trouble getting to sleep, staying asleep, and overall quality of sleep. It's made a tremendous difference in our lives - because when you wake up having a good night's rest, the quality of your day is better. Better night, better day. Sleep is important. My husband and I both highly recommend this product!

Helps me sleep!

Review by Verda (Posted on 9/25/19)

Overall Rating

I have had trouble sleeping for the past 10 years. I still have issues, but with help from the Ultra PM I was able to fall asleep right away and would wake up a couple of times and then go right back to sleep. When KUPM was discontinued I searched out if there was a replacement and found this Kavinace OS. I've been taking only one every night and I do wake up off and on but still feel refreshed when I do wake up in the morning. I do not feel groggy with a hangover like feeling some sleep aids have. I have recommended this to others and if you have a hard time falling asleep and staying asleep till morning I suggest taking one or up to two of these. The OS formula helps me fall asleep right away but I do wake up off and on more than when using the PM. I may need to start using two and see if that will keep me asleep for longer periods like the PM did.

Assessing and Hopeful

Review by Jane (Posted on 9/24/19)

Overall Rating

I’m still assessing. Kavinace Pm was my go to for years. Currently with the OS I sleep about 2-3 hours, wake for the bathroom, then usually fall back asleep without issue unless I have emergent life stuff on my mind, then nothing much helps. I will say I’m hopeful. I wake easily in the morning. The Ultra PM seemed to help me go to sleep faster, but not by a whole lot.

Can't sleep without it!

Kavinace OS helps me get a full night's sleep without waking up in the middle of the night. I used to take the Ultra PM and this works just as well for me!

Not pleased

I find I do not get as good a nights sleep with the OS as I got with the Ultra PM. Wish it was still available.

Great Sleep Aid

Since taking Kavinace OS, I have been sleeping very soundly. Great Product and I am glad they brought it back, new and improved. The results from the Ultra PM and the OS are very similar for me. Both work great!

Slept long and well!

Works great! So far feels about the same as the Ultra PM, but need a few more nights...

I like it, but it’s not as good as the original

Review by Lisa (Posted on 9/18/19)

Overall Rating

For me, this is not as good as the ultra pm which I was previously taking. I do notice as I keep taking it, not every night, it’s working better. I’ll have to give it some time.

So far I don't find this product to be as effective

Review by Michelle (Posted on 9/18/19)

Overall Rating

I am not falling asleep as quickly and I'm not stay asleep as long. I used the ultra pm for years and was always satisfied with my quality of my sleep and how refreshed my brain felt after waking. With the OS, I don't have that feeling of being rested and refreshed in the morning.

New version is equal to the old for me

Review by Tawn (Posted on 9/18/19)

This new formula does exactly what the original did, which helped my poor sleep issues. For me, the results are exactly the same as the former Kavinace.

I am disappointed in this product

Review by Joy (Posted on 9/18/19)

Overall Rating

I tried taking this three days in a row and appeared to get no benefit from this product. I was previously using KUPM and I am so sad that it is no longer available as it really really helped with my sleep.

Great product

Review by Suan (Posted on 9/18/19)

Overall Rating

I fall asleep within an hour and sleep soundly. If I am awakened, I'm able to fall right back to sleep. I only take one instead of the recommended two. No tired feeling in the a.m. I used the ultra pm previously and the OS seems to work very similar.

Didn't work for me

Review by Patty (Posted on 9/18/19)

Overall Rating

I had been using the Ultra PM for years to help with my sleep problems and it worked great. When it was taken off the market I tried Power Off which works pretty well for me as a replacement. I bought the Kavinace OS to give it a shot hoping it might work as well as the original, but I just didn't feel anything. Hopefully it will work for some. I will be going back to the Power Off.

Truly helps me sleep

Review by Shannon (Posted on 9/18/19)

Overall Rating

I have severe anxiety after having my last child and this helps my brain calm down so I can get the rest I need. I’m finally able to get good, quality sleep. In the past, my anxiety was very high and my brain wouldn’t rest while I slept so I would wake up all the time. Kavinace OS is a lifesaver for me.
