Cognium Fails To Use It's One Good Ingredient Well

Natrol Cognium Memory Tablets are made using one key, "clinically studied" ingredient, which is silk protein hydrolysate. While it is then joined by a number of other ingredients, these are primarily used for their effects on the taste or texture of the product, rather than brain health.

The problem with using a lone ingredient to make a supplement work is that it has to be very effective, otherwise there is nothing to fall back on. In this case, Natrol actually chose a good ingredient to base Cognium on in silk protein hydrolysate, they just didn't use it effectively.

Rather than use an effective dose of their key ingredient, they chose to use a tiny amount, likely in order to save money. This allowed the company to present all of the clinical studies to support their product, despite the fact the concentration would not produce the same results.

They then used a lot of smoke and mirrors with a quite extensive "other ingredients" list, despite the fact that not one of them had any effect on brain health or memory.

This means that, while Natrol Cognium for memory is not cheap to begin with, it would become extremely expensive, to the point of being entirely uneconomical, if you actually wanted to get it to work. What's worse is that this could also put you at risk of experiencing side effects as well.

That's why, if you want to spend your money on a brain health supplement, we suggest you go with Hunter Focus instead. This will actually help to keep your mind sharp and focused, while being far cheaper than what it would cost to get Cognium to work, making it the smart choice.

Customers Cognium Reviews

Ignoring the few fake ratings and removing those leaves Cognium with an accurate score of just below 4* which is not hugely lower than what the standard unfiltered rating. 

Reviews that describe a positive experience suggest that Cognium helped to improve memory, clarity, and brain health. However, almost every review of this kind came with an asterix, like only helping in the short term, a small amount, or when a person had early onset dementia.The negative experiences people describe when using Cognium are a lot more telling though. Many people said they felt no effect on their memory, focus, or brain health, but, what is more worrying, is the extensive list of side effects people said they experienced. This included intense headaches, diarrhoea, brain fog, extreme irritability, and tinnitus. 

The positive results show what we expected to see, in that the key ingredient of the tablet can support your brain, it just has to be used in much larger doses than are present in Cognium in most healthy adults. However, the extreme side effects people experienced while using Cognium just add another reason why this supplement isn't worth taking a chance on.

Natrol Cognium For Memory Tablets Ingredients

Silk Protein Hydrolysate (60%) - 100 MG

Silk protein hydrolysate is the common name for silk fibroin protein enzymatic hydrolysate (FPEH).

A protein found in the cocoons of silkworms, it is rich in the amino acid glycine and has been used in Asian traditional medicines for generations, due to a belief that it can protect various parts of the body from being damaged and boost memory and the immune system.

The effects on memory that Natrol claim have been "clinically shown" are indeed true. In fact, studies show it is able to significantly improve memory in as little as three weeks, rather than the four weeks that Natrol list on the Cognium box.

Unfortunately, what Natrol fail to say is what dose has been clinically shown to produce these effects. This is because, while the optimal dose of FPEH is listed at 400 to 600 mg per day, and even the minimum dose is set at 280 mg per day, Cognium contains just 100 mg per serving (1).

This means, short of taking 3 to 6 times the recommended dose, which would get very costly, require you to take between 6 and 12 tablets each day, and risk severe side effects, the key "clinically studied ingredient" in Natrol Cognium is likely to do nothing for your memory at all.

Other Ingredients

While silk protein hydrolysate is the unique ingredient that powers Natrol Cognium Memory Tablets, there are a number of other ingredients present in them as well. Most are used mainly to improve the taste or texture of the tablets, but they can also have other effects as well.

These ingredients include dicalcium phosphate, microcrystalline cellulose, maltodextrin, glyceryl monostearate, silicon dioxide, croscarmellose sodium, stearic acid, magnesium stearate, methylcellulose, and glycerin.

Silicon dioxide, microcrystalline cellulose, glyceryl monostearate, stearic acid and glycerin are all used exclusively to stabilise the product and improve its texture.

Dicalcium Phosphate, magnesium stearate & Croscarmellose Sodium

Dicalcium phosphate is a compound made of calcium and phosphate that is used in the process that converts the ingredients into tablet form. It can also offer some mild benefits to the production and maintenance of bones, teeth, DNA, and cell membranes.

However, it can also cause side effects like, nausea, vomiting, frequent urination, poor appetite, and gastrointestinal issues, and should not be used when pregnant or nursing (2).

Magnesium stearate, croscarmellose sodium, and methylcellulose also help to create the bulk and texture of the tablet, while the latter two have the added benefit of helping to make it easier to digest (3)(4).


Maltodextrin is an artificial sweetener that has the same number of calories as regular sugar.

It provides no other health benefits and is used solely as it is much cheaper. It will sweeten a product just the same but also spikes your blood sugar much faster, making it a far more unhealthy alternative (5).

Natrol Cognium Memory Tablets Review Conclusion

Cognium is powered by an ingredient proven to improve memory, concentration, and focus. Unfortunately, with the company being cheap and using only a tiny amount, it is incapable of producing the desired effects unless you take huge doses that are unsafe and uneconomical.

That is without even mentioning the extreme side effects people have mentioned even when only taking the recommended daily dose of Cognium. That is why we recommend people looking for nootropic supplements consider trying Hunter Focus instead. One of the best products of its kind, Hunter Focus can deliver all of the benefits that Cognium promises and more. Given that it is also safer and far cheaper than what you would pay to get any benefits from Cognium at all, it is simply a better memory supplement in every way.
