Kavinace Review 2019 – Pro’s and Con’s

KavinaceWhat is Kavinace

Kavinace is a powerful dietary supplement designed to reduce anxiety and promote relaxation. According to the official website, Kavinace can also improve sleep quality by supporting healthy levels of GABA for better stress management and relaxation.

The formula is produced by the U.S. company NeuroScience, the same business that provides another popular supplement – AdreCor.

Kavinace includes three powerful active ingredients (Vitamin B6, Taurine, and Phenibut) that have been shown to reduce the symptoms associated with mild anxiety, stress, irritability, sleep issues, and hyperactivity.

Kavinace Ingredients

Kavinace includes the following ingredients: Vitamin B6 (as pyridoxal 5-phosphate) 2 mg and Proprietary Blend (Taurine and 4-amino-3-phenylbutyric acid HCL) 950 mg.

Other ingredients: Microcrystalline cellulose, Vegetable capsules, and Magnesium Stearate (vegetable source).

Benefits of Kavinace

Kavinace’s formula includes three active ingredients which are promised to solve problems of anxiety, sleep issues, uneasiness, crabbiness, and hyperactivity.

The key component of Kavinace is4-amino-3-phenylbutyric acid HCI, a derivative of GABA known as Phenibut. Most recent clinical trials and research support the idea that Phenibut is the only known form of GABA that can cross the blood-brain barrier. This is of crucial importance. Most GABA-based supplements on the market rely on pure GABA (or other substances that raise GABA levels) to produce the desired effects. However, GABA alone cannot penetrate the blood-brain barrier, which means the so-much-needed nutrients will not be delivered to the brain and a huge chunk of them will just be lost.


Phenibut, on the other hand, helps inhibit the excitatory neurotransmitter known as phenylethylamine while also increasing GABA levels by binding to GABA receptors. The whole process will result in increased feelings of calmness and good results fighting the symptoms of anxiety and mild depression.

Raising GABA levels promotes feelings of calmness and anti-anxiety.
At the same time, other ingredients in Kavinace like taurine help to boost your cognitive energy while helping your brain in other ways. Here’s what the manufacturer has to say about including taurine in Kavinace:

Taurine is an amino acid that works to regulate the levels of water and mineral in the blood. Taurine is also known for its antioxidant properties which allow it to offer excellent protection to the brain against free radical damage. Clinical research has also shown this amino acid to support physical and mental performance, which is one of the reasons Taurine is such a popular ingredient in energy drinks and pre-workout supplements.

How Much Does Kavinace Cost?

Kavinace is available in bottles of 60 capsules at $48.00 and bottles of 120 capsules at $82.00. The recommended dose is 1-2 capsules taken one or two times daily. Do not take more than six capsules a day.

As for buying options, Kavinace can be purchased from a variety of online stores, some of them will even offer discounts and promotional prices. What we find interesting is that Kavinace cannot be purchased from Amazon.com, although all other NeuroScience products are listed in the store.

Potential Kavinace Side Effects

Kavinace is a safe supplement to take with very few associated adverse effects. Some people have experienced sleepiness, dizziness, or gastric disturbance. Due to the inclusion on Phenibut, some users may experience an itchy sensation around the backward of the neck and near the eyes and the mouth.


  • Kavinace is produced by a reputable US company
  • The formula contains a powerful amino acid in the form of Taurine
  • Kavinace is one of the supplements that are praised and liked by consumers.


  • Kavinace is quite expensive compared to other similar brain supplements
  • One of its core ingredients, Phenibut, has been associated with several side effects
  • While the three active ingredients have been proven to work, there is no clinical study to support the effectiveness of the whole formula

Final Verdict

Overall, Kavinace looks like a decent depression supplement for managing anxiety and stress. The formula includes some powerful ingredients that promote GABA activity which causes relaxation calming the mind and the body of the consumer.

However, there are two main issues with Kavinace. First, is the complete lack of clinical evidence showing that the formula is as efficient and safe as claimed by the manufacturer. The second problem – and this one are common to all GABA supplements – is the possibility of gentle withdrawal. We firmly recommend not taking other medications that have soothing properties while using Kavinace.
