Product Overview


  • Dietary Supplement
  • Serotonin/GABA

Kavinace combines two powerful ingredients that together effectively address symptoms of stress, anxiousness, and sleep issues. This formula contains the GABA derivative 4-amino-3-phenylbutyric acid, which easily crosses the blood-brain barrier and acts as a GABA agonist. Kavinace also contains taurine, which functions as a calming amino acid. Taurine is a GABA agonist and may increase GABA levels by increasing synthesis, preventing breakdown, and blocking reuptake of GABA Kavinace also includes vitamin B6, an important cofactor for the synthesis of GABA.

Suggested Use

Take 1-2 capsules one to two times daily.

Other Ingredients

Microcrystalline cellulose, vegetable capsule (HPMC, water), and magnesium stearate (vegetable source).


Use under supervision of a licensed health care practitioner. Consult your health care practitioner before taking with sedatives. If you are pregnant or nursing, consult your health care practitioner before use.

Keep out of reach of children.

Amazing product!

Posted by 4669118653537827316 on Sep 29, 2016

I highly recommend Kavinace (Neuroscience). I am a lifelong insomniac and this has made a world of difference. I take 3 and sleep for 8 (sometimes 9!) hours with no after effects or struggle to wake up. Amazing! :)

Worked for me in calming the mind for sound sleep

Posted by 5753101792225088027 on Aug 23, 2016

I had to take 3-4 capsules per day in order to get the effect I desired - with this dosage I had great results. I exercise and stretch but am very busy and work a lot, so it's often hard for me to fall asleep and/or stay asleep. When I take Kavinace, I have an easy time falling asleep and I don't wake up in the middle of the night with my mind full of to do's for the rest of the week.

This is a great product! I don't use it every night but every so often I have chocolate too late in the day or I just know that my monkey brain is not going to settle down for the night and Kavinace does the job. thanks.

Didn't work for me.

Posted by 5284831276510002714 on Jul 03, 2016

I read that this product only works if you are low in the GABA neurotransmitter. I was so hopeful that it would. Sadly it only made the depression and anxiety worse and offered no sleepiness at all which I need for insomnia. I probably should have had my neurotransmitters tested first. I only took one pill to discover this. The Kavinace Ultra PM worked great for sleepiness but I reacted poorly to the 5HTP. I wish I could find a happy medium from this great company.

Doesn't work (for me) for insomnia

Posted by Reviewer3163705 on Jun 19, 2016

This came highly recommended by my friend who has the same insomnia issues I do. She swears by it. So even though it was $44, I purchased it. I have sleep maintenance insomnia that hits like a mac truck during the week before/of my period. And when I wake up after 4 hrs of sleep, even after taking this, and melatonin, I do not fall back asleep. So in essence this was completely ineffective for me. Money wasted. Don't get me wrong. Price is what you pay; value is what you get...if this would've worked for me, I would've happily continued buying this, regardless of the price. Back to the drawing board. ps- during these women times, nothing helps me go back to sleep: melatontin, calm magnesium powder, valerian root, doing meditation etc. Nothing. If anyone has anything that has worked for them, please let me know!
