Cognium Review

Natrol Cognium is a popular natural nootropic supplement that has been around for a long time. It is not as widely acclaimed as some other supplements, but the fact that Cognium is constantly featured in TV and online ads makes you think it’s at least worth considering.

While there are many Cognium Natrol reviews praising the supplement for its cognitive enhancement effect, there are also plenty of testimonials claiming that Cognium did nothing it promised to do. So is there any point in taking Cognium for a sharper mind or should you go for another product?

What is Cognium?

You have likely heard about Cognium at least once in your life, but what is Cognium exactly? Cognium is a brain health supplement produced by Natrol. On Natrol’s official website, it is claimed that Cognium has been clinically proven to improve memory and recall. According to the marketing information, you should see the results within four weeks.

The supplement is also stimulant-free, which may be important for those who plan to combine Cognium with other medications. Another advertised benefit of Cognium is its antioxidant effect that prevents the brain from premature aging.

Cognium Ingredients

If you look at the ingredients in Cognium, you will see a fairly long list of substances that supposedly went into making this nootropic supplement. However, the truth is that all those Cognium ingredients, besides one, are filler ingredients. The only active ingredient in the Cognium formula is CERA-Q.

We have checked numerous Natrol Cognium reviews, and they all agree on one thing: in order for an effective nootropic supplement to include just one active ingredient, it has to be nearly miraculous. So does CERA-Q have what it takes to give you the effect advertised by the natural Cognium nootropic?

CERA-Q is a branded and patented powder that contains 60% of silk protein hydrolysate, derived from the threads of silkworm cocoons. If you are wondering whether silk protein hydrolysate could actually qualify as a nootropic, you are correct in your doubts: its most famous use is in Cognium, and besides Natrol, only a few other companies chose it as an ingredient for their nootropic supplements.

According to Natrol, CERA-Q has been the subject of multiple human clinical studies and was found to enhance the blood flow in the brain, improve focus, give you a better memory and recall, and prevent brain aging by acting as an antioxidant.

The promised effect of Cognium looks very appealing to anyone who would like to boost their cognitive function, but there is very little evidence supporting Natrol’s claims. On their website, they refer to several studies, but after taking a detailed look at some of them, we can say that none of the studies looks particularly credible. Most of the studies come from Korea and from the same group of researchers, which looks rather suspicious.

Our Thoughts on Cognium’s formula

Natrol makes some very bold claims regarding the anticipated effect of Cognium on brain function, but there is just not enough evidence that it has any impact on the cognitive activity at all. The featured studies are completely unconvincing, so before there are more credible studies published in respectable sources, we choose to believe that Cognium and CERA-Q do little to nothing for your mental abilities.

The rest of the Natrol Cognium ingredients are mostly used as filler and secondary agents for achieving the right tablet texture and organoleptic qualities. They have no effect whatsoever on your cognitive performance and should not be taken into account when analyzing the formula of Cognium.

Cognium Side Effects

CERA-Q, the only active ingredient in Cognium, has not been featured in enough credible studies to paint a complete picture of its potential side effects. However, it’s worth noting that CERA-Q is essentially a protein, so the risk of contracting side effects is rather low, especially if you follow the recommended dosage of 2 tablets a day and don’t have any pre-existing conditions that can increase the risk of experiencing adverse effects.

In our quest to investigate Cognium from all aspects, we have come across a Natrol Cognium review claiming that the supplement not only never delivered the expected result, but also led to nausea, vomiting, and headaches. And while there are not too many Cognium reviews talking about the potential Cognium side effects, you should still approach this supplement with caution.

Does Cognium Work?

Even after learning about the potential side effects and the questionable formula of Cognium, you are probably still wondering: does Natrol Cognium work? In fact, the question “Does Cognium work?” is the most common one among people who are only considering trying the supplement.

The short version of our answer to this question is no. The silk protein, which is the number one and, essentially, the only active ingredient of Cognium, has not been proven by any reliable studies to have any effect on the cognitive function.

The idea that Cognium does not deliver results is further backed up by the fact that the product does not contain any additional ingredients such as vitamins and natural nootropic agents. Relying on a single ingredient — in this case, CERA-Q — is highly unlikely to give you a noticeable cognitive boost.


There are many things that can be said about Cognium, but the bottom line is that it is simply not a good nootropic. Its formula is extremely limited, and the one ingredient that is included in it does not have a proven effect on your cognitive function.

We have only seen CERA-Q featured in a couple of nootropic supplements, which speaks volumes — compared to other popular nootropic ingredients, CERA-Q is virtually obscure and understudied. The Cognium mind effects are either subtle or nonexistent, because we have not found a single genuine Cognium review claiming that this supplement has really helped someone function better.

Overall, despite the affordable price, Cognium is currently not among the nootropic supplements we would recommend to our readers. You can achieve a much better effect with some of the other products featured on our website.

Frequently Asked Questions

Is Cognium safe to take?

Despite Natrol’s claims, there have not been enough credible studies to confirm the safety of Cognium’s only ingredient, CERA-Q. For this reason only, we cannot say that Cognium is a safe supplement until there are more tests supporting this notion.

Is Cognium legal?

Although Natrol has been repeatedly involved in legal troubles surrounding its most famous product, Cognium, there is currently no evidence to support the idea that this supplement is illegal. Cognium is freely sold on popular platforms and has been around for years, so while it’s not the safest or most effective nootropic out there, it looks fine from a legal standpoint.

How much does Cognium cost?

Cognium is a fairly affordable supplement when compared to some other options, but the price largely depends on where you decide to buy it. On average, a single bottle of Cognium containing 60 tablets will cost you between $20 and $30, although if you choose to subscribe to the product, you can save an additional 5 to 15%.
