Kavinace, from NeuroScience, is formulated to help promote a more restful state. By combining three potent ingredients, Kavinace may help alleviate irritability, difficulty sleeping, stress, and anxiousness.

Kavinace Frequently Asked Questions

Q: What can Kavinace do for me?

A: Those who buy and use Kavinace properly will find that it offers many benefits that set it apart from similar products:

  • Provides GABA support
  • Promotes healthy sleep
  • Helps manage stress and anxiousness

Q: How Does Kavinace work?

A: Kavinace combines two powerful ingredients that have shown to be effective at addressing symptoms of stress, anxiousness, irritability, hyperactivity, and sleep problems.

Included in this formula is the GABA derivative, 4-amino-3-phenylbutyric acid (beta-phenyl-GABA). 4-amino- 3-phenylbutyric acid easily crosses the blood brain barrier, binds to GABA receptors, and may increase GABA levels. Additionally, 4-amino- 3-phenylbutyric acid appears to inhibit the excitatory neurotransmitter phenylethylamine (PEA).

Kavinace also contains taurine, which functions as an inhibitory amino acid. This amino acid, taurine is a GABA agonist and may increase GABA levels by increasing GABA synthesis, preventing GABA breakdown and blocking GABA reuptake. Taurine is an osmoregulator and neuromodulator, also providing neuroprotective actions against cellular insults such as free readicals, excess ammonia and excitotoxicity.

Vitamin B6 is included as an important cofactor for the synthesis of GABA, as well as other enzymatic pathways.

Q: Is Kavinace safe for me to use?

A: Kavinace has been found to be safe among its users, but it is always recommended that you consult an expert or physician prior to adding supplements to your daily regimen, especially if you are pregnant or are nursing, This supplement has a sedative nature and precaution and supervision is suggested. It is also not recommended for children.

Q: Why should you buy Kavinace from our online store?

A: If you have trouble sleeping, buy Kavinace from our online store. Also, if you have extreme difficulty falling or staying asleep, buy Kavinace Ultra PM—as this product contains 5-HTP to support serotonin production in your brain, as well as melatonin to help your body better control your sleep-wake cycle. Inevitably, if you need to buy a NeuroScience supplement online, Accutrition is one of the most reliable places to buy them on the Internet.

I have had trouble sleeping for years and have tried many over the counter products. A co-worker told me about Kavinace and I am so glad I tried it. I take one when I go to bed and it helps me to feel relaxed enough to be able to fall asleep. If I wake up in the middle of the night, I take a second one. I find that I usually wake up feeling refreshed and don't have the hangover feeling that some other products give me.

Great product

I have had trouble sleeping for years, I have been on countless prescription sleeping meds all of which I had trouble with and ultimately made me tired and groggy the next day. I started taking kavinace more than a year and a half ago and I cant say enough good things about it! I fall asleep quickly and I sleep through the night which is my biggest problem. If I do happen to wake up, it’s for minutes.. not hours. I couldn’t live without this product!

This Product Helps My Anxiety

Review by Rebecca (Posted on 3/9/2019)

I suffered a brain injury nine years ago and since then have struggled with anxiety, something I never dealt with prior to the injury. My doctor recommended I try this product. It works for me. When I take it, no anxiety, if I don't, it comes back. I tried stopping because it is so expensive but have decided it is absolutely worth it for me. I have no side effects and love feeling like myself.

Makes a BIG difference!

I’ve come to realize that I’ve suffered from anxiety and poor sleep habits my entire life. After talking to my doctor about how “off” I always felt because of lack of sleep, he suggested this. Within a week, I could tell a difference. My husband could tell too. I’m better rested. More productive. And I don’t dread things. I’m very happy with the change!

Kavinace = Life Saver

Review by Debbie (Posted on 2/26/2019)

Kavinace was recommended to me by my doctor to help me stay asleep. I followed the recommendations and it was somewhat effective. However, if I take 3 caps between 5 and 7 every night, I get solid sleep. I've been taking it for over 5 years now and it continues to be very effective. My Life Saver for sure!

It helps!

I am a lifelong insomniac. Though I have tried some of the ingredients in Kavinace individually, this blend has proven more effective than any single ingredient or other blend of the many others I have tried.

Kavinace has been the answer to my prayers. After using over the counter and then prescription sleep aids with very little relief, I was exhausted and frustrated. My naturopath suggested I try it and I am so happy that I did! They seem a bit pricey for what they are, but, so far, that has not stopped me from purchasing them yet.

Great sleep aid

My functional doctor believes I don’t produce enough GABA, so he recommended I try Kavinance. It works wonders for my sleep. I no longer lay in bed for hours trying to fall asleep and then wake up multiple times a night. I fall asleep like a normal person now, wake up a lot less during the night, and wake up feeling ready for the day!

I took this for a week to try to help me sleep better and I saw very little change. I didn't have any side effects or anything like that, it just wasn't what I hoped. It works great for my wife, so just because it didn't work for me doesn't mean it won't work for you. I still continue to purchase this for her.

Thankful for this!

Made a difference in my life

Review by Dawn (Posted on 12/8/2016)

Overall Rating

My wellness doctor had me take a test, and when the test came back it explained a lot of things about my health. I was really, really low on GABA, and a couple of other things. She put me on Kavinace and Travacor to help with lowering my anxiety, help stop my mind from constantly thinking and worrying, help lower my stress, and help me sleep better among other things. My regular doctor just wanted me to see a psychiatrist instead of helping me with these problems. I thank God I found a Wellness doctor and have been on the road to recover since 2014. My life is not 100 percent, but I have improved and can honestly say it is because of these 2 products along with a couple of required vitamins and some *very little* life style changes. I don't think people understand how much we are missing these amino acids and how our lives are affected without them. Kavinace has been a "life saver" and I don't mean that lightly. I am moving forward and getting better every day.

I had my son see my Dr. and get the testing done as well and I knew before they test came back that he was going to need aminos as well, because of his issues. Sure enough he did, but for him he is using Kavinace and 3 other products. We can already see a difference in his mood, and he can see a difference in his sleep.

Please understand, you should not buy Kavinace thinking oh this is a sleeping pill.. it is not.. it is more than that, so please get tested before you take this or give it to one of your children. You can go to their website for more information.

I like this product

I have been dealing with depression since I had an illness with a lot of pain. Now, the illness is gone, but the depression is keeping me unproductive and not enjoying life. When I take this product, my thoughts stay manageable and I can do things that I would not be able to do otherwise. Drinking alcohol with Kavinace, even just a small amount (half a glass of wine) gives me a headache, and if I drink 2 cocktails with it, it results in hangover-like symptoms. I'd rather take this supplement than drink alcohol anyway. Another very good thing about this product is that I do not have to take it all the time. I can just take it when I need it. :)

Overall Rating

Our pediatric psychiatrist, who is Board Certified in Holistic Medicine, put both of our sons on Kavinace + several other supplements to help with the anger, aggression, anxiety and stress levels associated with their ADHD, Sensory Processing Disorder and Explosive Disorder. Within weeks of starting the supplement regimen, they were different boys. Last month, we ran out of the Kavinace and it took a couple of weeks for me to get it ordered. We saw noticeable changes in the boys and their anxiety by not having the Kavinace for two weeks. Our psychiatrist also recommended it for me because of the stress I have from having multiple children with mental health disorders. The Kavinace has worked wonders for me as well. I don't cry nearly as often as I was! Great product!

I used to wake up 4-5 times a night (sometimes more) and in the morning I'd have a lot of neck and shoulder pain. It turns out I clench my teeth at night. My chiropractor recommended Kavinace. I was very skeptical when he sold it to me. Lucky for me, it works! It relaxes me and allows me to sleep through the night. I take 2 at night and sleep soundly till morning. Now, I just buy the Kavinace on line and I don't need to see the chiropractor. I highly recommend it.
