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.

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!

Seems to work OK

Posted by Reviewer2235337 on Oct 24, 2013

I seem to notices some feelings where I was numb not sure if its from the GABA or now, my DR said this is the type you wants Pharma Grade.

Not Calming, but Does Help Sleep

Posted by Reviewer2806801 on Jun 22, 2013

I was hoping this might help me weather occasional moments of stress a little better. It didn't seem to make a difference there for me (might be different for others - lack of GABA may just not be my issue there). However, it did make me really sleepy. For the rest of the bottle, I'm just taking one before bed instead.

Good in combination

Posted by 5539485648441357020 on Sep 12, 2012

These work well in combination with other sleep support nutrients and herbs (passionflower, theanine, GABA, 5HTP, etc). I don't find they are enough on their own but all in all, they are a good product. Perhaps a little expensive.
