Kavinace Review – 12 Facts You Need to Know

By taking 2 capsules at bedtime, Kavinace claims to improve the onset, duration, and efficiency of your sleep while addressing oxidative stress.

A supplement got big shoes to fill when it promised the world to be the “best brain supplement on the market.” Kavinace OS makes this vow… but do they really keep it up?

This outstanding confidence in the Kavinace OS presentation motivates our team to get a closer look at this product, to help you make a better decision whether this supplement worth your mental health and money. 

We study the customer reviews, ingredients, and all the other stuff related to this product to explore if it really has this magic capsule & emulsion.

So, let’s check out the detailed overview…

What is Kavinace?

Kavinace® OS by neuroscience is the newest formulation for a quick sleep. The product first comes with the name “Kavinace Ultra PM,” but now they changed their previous formula and comes with the name Kavinace® OS that claimed to improve the onset, duration, and efficiency of your sleep while addressing oxidative stress.

The product comes in three forms:

  • Kavinace OS
  • Kavinace OS Emulsion 
  • Kavinace OS Emulsion Pouch

About Manufacturer

NeuroScience, a company, working since 2000, designed this supplement. It specializes in proprietary blends of amino acids for improved functioning of the human body, immune and nervous system. 

Some other products including in their catalog are:

  • Calm CP
  • NeuroBiota
  • Focus DL
  • ImmuWell

When we visited the company on the Better Business Bureau, we found two business profiles with the same name, “Neuro Science Inc.” Both weren’t Better Business Bureau accredited.

After in-depth research, we also came to know that the U.S “Food and Drug Administration (FDA) warned Neuroscience regarding Kavinace’s ingredient. Therefore they took off their product “Kavinace Ultra PM” from the market and come up with a reformulated product named “Kavinace OS.”

Kavinace OS and FDA Warning (APRIL 10, 2019)

In April 2019, Food and Drug Administration (FDA) issued a warning letter indicating that one of Kavinace’s ingredients contains — 4-amino-3-phenyl butyric acid HCl (AKA phenibut) and does not fit the FDA’s definition of a dietary ingredient. Thus labelling is false or misleading in any particular and cannot be sold in over-the-counter nutritional supplements.

More importantly, FDA stated that according to existing regulations, Phenibut is not an herb or other botanical; not a vitamin or mineral; not an amino acid nor even a dietary substance for use by man to supplement the diet; thus, it is not a dietary ingredient.

Kavinace Claims

Kavinace Ingredients analysis

The main ingredients of their proprietary blend are:

  • L-Theanine
  • Resveratrol
  • Astaxanthin

Others are melatonin, zinc, magnesium, and selenium.

L-Theanine 

It's an amino acid that helps to promote mental relaxation without drowsiness.

Journal of Clinical Psychiatry suggests that L-theanine decreased anxiety and improved the symptoms of schizophrenia or schizoaffective disorder. Another study reported that it increased relaxation without causing drowsiness or reduced resting heart rate.

Resveratrol

It’s a plant-based compound that acts as an antioxidant. Moreover, it also possesses anti-inflammatory activity. A study published in Front Aging Neuroscience reports that it can protect brain cells from damage.

KeyNote: According to Healthline, the above research is intriguing, which limits its immediate use as a supplement to protect your brain. Scientists still have questions about how well your body can make use of supplemental resveratrol. Additionally, the New York Academy of Sciences reported that the bioavailability of resveratrol is still under debate.

Astaxanthin 

It’s a carotenoid pigment linked to multiple health benefits, including healthier skin, endurance, heart health, and joint pain. A study published in Clinical Therapeutics reported that it could improve blood flow and can lower oxidative stress in smokers and overweight people.

KeyNote: We could not find any clinical research that claims Astaxanthin being a nootropic ingredient.

Melatonin

It’s is a hormone that commonly used to improve sleep in different conditions and insomnia. 

Karnataka Institute of Medical Sciences conducted a study on 50 people with insomnia which showed that taking melatonin two hours before bed helped patients fall asleep faster with enhanced overall sleep quality.

Are Kavinace OS Ingredients Safe And Effective?

Although this supplement contains minerals and L-Theanine, which may provide you with a mental health boost; but talking about improved sleep quality, then we couldn’t find strong clinical evidence for the ingredients and its claims. 

Moreover, the supplement maker reformulated their product after FDA warning, but replaced ingredients might not be safe as in-depth ingredient analysis reported the following side effects:

Side effects of Resveratrol

Side effects of Melatonin 

Clinical drug investigation enlisted the following side effects:

  • Dizziness
  • Headache
  • Nausea 
  • Sleepiness

Possible hazardous drug interactions

Note: Not all users are expected to experience these side effects, but there is no guarantee that you will be able to avoid them.

How To Take Kavinace OS?

The official website suggests taking 2 capsules at bedtime or as directed by your healthcare provider. They further recommend not to exceed the proposed use.

Does Kavinace OS Provide 100% BrainPower?

Well, this supplement contains minerals that may provide you with a mental health boost. Moreover, L-theanine is clinically proven to decrease anxiety and increase relaxation without causing drowsiness. But the central proprietary blend lacks scientific evidence and possesses potential side effects that shouldn’t be ignored.

Additionally, after FDA warning against Kavinace’s ingredients, the supplement makers take off their product from the market and come-up with the reformulated version.

The reformulated formula might be useful, but we are not sure about its 100% effectiveness and safety of their latest formula.

Warnings for Kavinace OS Users

The official site warns to consult your healthcare provider first, especially if you are pregnant or nursing.

Some other general warnings for Kavinace OS users include:

  • Avoid if you are on medication or with a known pre-existing medical condition as resveratrol and melatonin possess potential dangerous drug interactions
  • Keep out of the reach of children 
  • Consult your physician first before incorporating the Kavinace OS supplement into your daily routine

Customers Reviews

I had bought this product before, and it helped with my sleeping; however, I believe the formula has changed, and it did not work for me this time.
Vicki Bailey
I think this may be a fake product. It arrived unsealed with 70 pills instead of 60. I am returning it. From now on, I will be more careful when I purchase vitamins. I actually think kavinace os does work, though, but I would be careful where you purchase it.
This product is entirely off the mark. It's not worth the headache you would wake up to. Save your money

Kavinace OS Alternative – Consumers' No. 1 Choice

This product possesses some good qualities as it contains essential minerals to provide you with a mental health boost. But we’re a bit concerned about its proprietary blend, which lacks high-quality clinical research and associated with potential side effects.

Moreover, the product is entirely off the market once after a warning letter from the Food and Drug Administration (FDA) thus, we can’t stand behind this supplement with 100% assurance.

To maintain optimum brain functioning, we always recommend our readers to try adding exercise and natural foods enriched in brain-boosting ingredients into your diet instead of synthetic drugs and supplements. 

But still, if long-term cognitive enhancement and memory is your goal, we suggest using a supplement that contains ingredients list with clinical support, 100% effectiveness and with no potential side effects. 

Among the best supplements, we've ever come across is Mind Lab Pro. It's clinically proven to be the right choice of consumers without experiencing any side effects.

Conclusion

Our final thoughts! We like some aspects of this product as it comes in numerous versions. You can either have a capsulated version or emulsion. But when it comes to the nootropic side, there are only three ingredients that require further clinical research to prove its effectiveness before we can recommend it as an effective sleep aid.

If you’re looking for a total cognitive optimization and really want to invest in your mental health, then give Mind Lab Pro a try, the most potent nootropic with 11 clinically proven ingredients on sale right now.

5 Total Score
Not Recommended!

A total of three nootropic ingredients in $49 are highly pricey that even need more clinical research to prove its effectiveness. Moreover, the product is reformulated after the Food and Drug Administration (FDA) warning letter. Due to the multiple concerns listed above, we can't recommend this supplement with 100% assurance. Our recommendation still stands with the top-rated supplement Mind Lab Pro which contains clinically-tested 11 genuinely natural ingredients that help increase your mental performance while avoiding any stimulants or additives. It also offers free shipping and a money-back guarantee.
