Addiction / Withdrawal / and Possible Dependency
I’m not someone who typically suffers from anxiety or insomnia, but like most folks I have my good and bad days. Up until recently, if I had a hard time falling asleep or felt anxious, I would simply write it off and deal with it.
However, in the interest of helping my readers find something that can help in this area, I decided to do a bit of research. During my research, I came across a supplement called Kavinace, which is the focus of this review.

What is Kavinace?
Kavinace is an all natural supplement designed to help promote relief from anxiety / irritability, as well as help people suffering from insomnia and sleep issues. It’s marketed by a company called Neuroscience, and is sold almost exclusively online.
Its primary ingredient is 4-amino-3-phenylbutyric acid (also known as Phenibut), which is a GABA derivative that acts to inhibit excitatory transmitters in the brain. The theory is that it allows GABA to cross the blood brain barrier by adding a phenyl ring around it. (Source)
Typically GABA cannot do this on it’s own, at least in sufficient quantities.
Other ingredients in Kavinace include taurine, which is a potent antioxidant that products against toxicity from various substances, and Vitamin B6.
Frequently Asked Questions About Kavinace
How Should I Take Kavinace
According to the label, you should take 1-2 capsules two times daily, and you should not exceed 6 capsules per day. While the manufacturer recommends daily dosing, this it not a good idea.
You will learn exactly why below.
How Long Does Kavinace Take To Work?
I also don’t think you should take more then 1 or 2 capsules TOTAL throughout the day. Phenibut has a way of creeping up on you when you least expect it.
You could be feeling practically nothing and then 1/2 hr. later feel all the effects at once.
One thing I also noticed is the effects are MUCH more pronounced when you take it on a completely empty stomach.
I’m not sure as to why this is the case, but my theory is that the ingredients are simply absorbed faster / more efficiently when there’s nothing else your stomach has to work on.
What kind of feeling should I expect from taking Kavinace?
While everyone’s body chemistry / makeup is different, the general consensus among most is that it provides a feeling of relief from anxiety, makes you less irritable, and can help you sleep better.
One thing I want to note is that it seems to take a VERY long time to feel the effects, in some cases close to 5 or 6 hours.
I have no idea why it takes that long but that’s the effect I got from it.
Can I Take Kavinace With Alcohol?
This is NOT recommended.
The primary ingredient in Kavinace (Phenibut), increases the effects of the inhibitory neurotransmitter GABA in the brain.
This is exactly the same way that alcohol works, and drinking any alcohol whatsoever will simply intensify the effect.
There are all sorts of adverse reactions that can occur if you combine kavinace and alcohol, including:
- Nausea / Vomiting
- Extreme drowsiness / sedation
- Loss of consciousness
- Potential respiratory depression
If you don’t believe me, read this.
It’s also not recommended that you drive while taking this supplement until you can assess your individual tolerance.
Can I buy it in stores?
The answer is yes and no.
You can’t find Kavinace in large brick and mortar stores like GNC, Walgreens, CVS, Rite Aid, or Vitamin Shoppe. Amazon doesn’t seem to sell it either, and the primary ingredient (phenibut) has been placed on their known prohibited products list.
However, there are many smaller, locally-owned vitamin stores that sell it. I would run a quick search for something like “supplements store near me” and call around to a few local shops.
My Personal Results
I had a chance to try out Kavinace, and I have to say that I think it is a VERY potent supplement. Because I’ve taken products containing phenibut in the past, including Phenibut XT, Somatomax, and Tranquilene, I had an idea of what to expect as far as results.
The first time I took it was in the morning on a particularly stressful day at work. It took awhile to kick in, but the effect was there. I felt an increase in mood and just generally had a positive outlook on the day ahead. Things that would normally stress me out didn’t.
Later that day I took 1 more capsule about 2 hours before bed, and felt very relaxed while I watched TV. It’s a bit hard to describe, but it’s almost like feeling the buzz you get from drinking a couple of beers or glasses of wine, but without the mind-slowing effects.
That night I had a GREATnights sleep. Usually I’ll wake up once or twice throughout the night to use the bathroom, but not this night. I slept straight through and woke up feeling refreshed and ready to tackle the day.
What’s interesting about Kavinace (and supplements containing Phenibut in general) is that the effects seem to linger for most of the following day, even without re dosing.
This is sometimes referred to as an “afterglow” effect.
So a quick story is in order to let you know how I originally learned about Kavinace. I had been experimenting with a substance called Phenibut over the course of a few months, and everything was working great. The substance gave me a calm, relaxed feeling, but didn’t leave me drowsy during the day.
Combined with a stimulant like Optimind, Phenibut gave me intense concentration and focus, but kept me level-headed and cool. It essentially eliminated any of the anxiety inducing effects of the stimulant, allowing me to work for hours on end.
It even actually worked as a fairly potent pre-workout supplement. Often I would take it about 2 – 3 hours before my workouts, and found that I not only was working out harder, but I seemed to be more focused.
Potential Addiction Issues
Then, I started reading stories on forums and addiction treatment centers about the potential for addiction and withdrawal symptoms from prolonged use of Phenibut.
If you’ve been taking Kavinace for a prolonged period of time, some signs of an addiction may include:
- Increased Anxiety
- Aggression / Irritability
- Cognitive deficit
Uh ohhh…Anyway, after ceasing use of Phenibut and going through a short (but unpleasant) withdrawal period, I started to miss the effects that Phenibut was producing.
In my quest to find something that would work similar to Phenibut, but without the withdrawal dependency aspect, I visited a local mom and pop vitamin store.
When I entered the store I was greeted by the owner, and I asked her if she ever heard of Phenibut.
Oh no, I don’t mess with that stuff. Too many issues, I’ve read too many horror stories about withdrawal / dependency, etc.
I then told her I was looking for something to help relieve anxiety, help me sleep, etc., and she recommended Kavinace.
She said she takes it twice a day, 1 capsule in the morning and 1 in the evening, and has been for years.
I asked her if she ever experienced any side effects or withdrawal symptoms from abstaining from it. She told me that she’s only taken a few days off from it ever since she started taking it, and only noticed minimal withdrawal symptoms like being pissed off in traffic.
I bought a bottle and when I got home researched the ingredients (at the time I didn’t know Phenibut was called 4-amino-3-phenybutric acid), and wouldn’t you know it….4-amino-3-phenybutric acid is Phenibut.
I thought about calling her up and telling her that what she was taking is essentially Phenibut, but she seemed “out there” to begin with so I didn’t bother.
The dangers of taking Phenibut long term are there. I talk about this in detail in my official review of Phenibut, so I won’t touch on it here.
- Works well to help relieve stress / anxiety
- Can be conveniently bought online and in stores
- Excellent for sleep
- Can also provide nootropic clarity and concentration in small doses
- Shouldn’t take it everyday, despite them telling you otherwise
- Unknown exactly how much Phenibut it contains
- Only available in small, local mom and pop vitamin stores
Does Kavinace work? I can say with a resounding YES. HOWEVER, taking Phenibut (or Kavinace) daily is a REALLY bad idea.
Not only does it have the potential to create REALLY bad withdrawal symptoms when you stop taking it, but Phenibut seems to build a tolerance very quickly.
Long term use should be avoided, but if you are looking to use it for just a short period of time then there is no reason that taking Kavinace should produce any negative effects unless you are particularly sensitive to it.
You’ll find you need more and more of the stuff to get the same intended effect, which is never a good thing for a supplement. If you do decide to use it, I would suggest you use it either sparingly (1 – 2 times per week), or not at all.

Have you used this supplement?
Please do not take this supplement. They will tell you that it is not addictive.
This is wrong
They will tell you there are no side effects. This is also wrong
They will tell you there are not withdrawals.
Again, this is also incorrect.
After taking Kavinace and Kavinace pm, I developed a cough. It was a bad cough.
The products have a tolerance. If you take 2 then you are going to need 4 to sleep to calm down etc.
It is also very expensive.
I got off of Kavinace cold turkey.
I experienced chills, shaking and needles all around my skin for 2 weeks. I now I feel so much better.
The best thing I experienced is that I no longer have that horrible cough. I don’t snore anymore either.
Please do not start this product.
If you do take it, stop!

What a nightmare!!
In Short: I would NOT recommend this to a friend.
Holy Cow! I thought this Kavinace Ultra PM was a Godsend for insomnia that I had been struggling with for an extednded time.
I bought it through a chiropractor and it was the answer! I was finally able to sleep and all was well.
I took 2 capsules every night for a little over a year.
I ran out and was unable to get another bottle for a few days....I was literally up ALL NIGHT (basically watched the sunrise) for those days until I got the new bottle and then it was back to sleepy town. I suspiciously asked the chiropracter if there was anything in the supplement that was habit forming and he said 'absolutely not' so I kept taking it.
Then I ran out again and the same thing happened.
So here I am now researching the ingredients and found out the phenibut is definately habit forming. ARGHHHHH.
I'm going to try and wean myself off by cutting back slowly.
I'm so so disapointed in this practioner for not warning me that this could happen. Please do your self a solid and DO NOT USE KAVINACE ULTRA PM.
Please wish me luck! Any suggestions for sleep would be greatly apprciated:)

Went to a functional medicine MD who recommended Kavinace. I was concerned about the Phenibut, but he didn't seem to be. Why bother with it if you can only take it occasionally? Might as well stick with an occasional Xanax. -Irene
That would be an option as well, though you need a prescription for Xanax, while Kavinace is natural and doesn't require a prescription.- Rob
