What is it?

iQuzil is an over the counter nootropic supplement and mental performance aid. It is marketed as a study, creativity, and productivity enhancement tool that is useful to people from all walks of life.

Their advertising claims that it is effective for improving memory, problem solving skills, and for increasing reaction time and alertness. It is also thought to be an energy booster that fights fatigue and keeps users mentally engaged for longer.

The most impressive nootropic product on the market is Memotenz. It has quickly developed a reputation as the go-to mental performance booster for people in the industry, and those on the outside of it are starting to take notice of it as well. Click here to learn more about Memotenz’s benefits and to see if it’s the right nootropic for you.

iQuzil Ingredients and Side Effects


Vinpocetine Caffeine Anhydrous Adrafinil

Vinpocetine: A synthetic chemical that is designed to mimic vincamine, an extract found in the common periwinkle variety vinca minor. Many people believe that vinpocetine has nootropic benefits for its users, however these claims are largely unsubstantiated by science.

The most documented effect of vinpocetine is that it can improve circulation throughout the body, including to the brain. There is some evidence that has shown that this may be of particular use to individuals with Alzheimer’s disease or dementia.

Vinpocetine is thought of as a neuroprotectant that may help in preventing the natural degradation of mental function that comes with aging. It may also have some antioxidant function and help regulate the brain’s molecular sensors, both of which can be useful in keeping brains active and functional as they get older.

There has been one study that suggested that it was useful for improving memory, however it has been criticized by other scientists in the field for making some critical errors in their methodology. It is still uncertain if vinpocetine can improve memory function in otherwise healthy adults, or if its effects are only beneficial for preventing neural decline.

The effects of vinpocetine are not well understood at this time, however there have been some serious concerns about potential side effects that scientists have been raising. It seems that vinpocetine can cause extreme drops in blood pressure pulse rate which have led to the death of at least one user.

There are also concerns that it can decrease the amount of white blood cells in users, which may potentially compromise their immune systems. This has the potential to turn into cellular death and in the long run could lead to apoptosis.

Other side effects that may potentially be related to vinpocetine include:

  • Abdominal cramping
  • Nausea
  • Night terrors
  • Dizziness
  • Flushing of the face

Caffeine Anhydrous: The dehydrated, powdered form of the common stimulant. There is no chemical difference between caffeine anhydrous and the caffeine that is found in foods and beverages.

Caffeine is the most consumed stimulant worldwide. It appears in coffee, tea, energy drinks, colas and other sodas, and in thousands of other products. It is not classified as a nootropic and it is not one of the products that our team recommends for inclusion in nootropic supplements, especially those that are taken daily.

The most notable effects of caffeine are that it reduces fatigue and increases energy levels and power output in its users. It can have some benefits to memory and cognition, however there is much less evidence that supports this.

One of the issues with caffeine is that it is short lived in its effectiveness and is often followed by what users call a “crash” period. The benefits of caffeine wear off within a few hours, and following this active period many users report feeling their energy levels take a sharp decline. This crash period may lead to increased fatigue, reduced cognition, and a general decline in mental performance.

There are also some other side effects that may be related to caffeine consumption, some of them serious. Some conditions that may potentially stem from caffeine consumption include:

  • Sleeplessness
  • Irritation and anxiety
  • Dehydration
  • Heart palpitation and arrhythmia
  • Stroke
  • Heart attack
  • Death

Adrafinil: A stimulant that was originally promoted in Europe as a nootropic before studies discredited those findings. Adrafinil has largely fallen out of favor since the isolation of modafinil, the active chemical that gives adrafinil its nootropic effect.

Modafinil is thought to be far more potent and far less dangerous than adrafinil, which has led to adrafinil being banned by several regulatory agencies including the World Anti-Doping Agency and New Zealand’s Medical Classification Committee.

Adrafinil is known for promoting wakefulness and fighting fatigue, however those are the only benefits to adrafinil that have been clinically proven. Some manufacturers have tried to sell it as a nootropic, however all data points to adrafinil having no significant impact on memory or cognition.

  • Orofacial dyskinesia
  • Suicidal ideation
  • Insomnia
  • Hyperexcitation
  • Numbness
  • Liver damage

Despite the stimulant effects of adrafinil it has not been linked to heart or blood pressure issues, as caffeine and most other stimulants are. It is not out of the question, however, that users with a history of heart or blood pressure problems could experience a potentially serious incident and it is wise to consult with your doctor before beginning use.

iQuzil Quality of Ingredients

iQuzil does not have any ingredients in their blend that our team classifies as an effective nootropic agent. All three of their primary additives are considered more effective as stimulants than they are as mental performance boosters.

Consumers should not expect significant boosts to their cognition, memory, attention span, problem solving skills, or other short-term enhancements. It is possible that iQuzil may have some neuroprotectant qualities, however those will not be noticeable to the vast majority of users.

In addition, all three have been potentially linked to extremely serious health conditions. Any one of the three is a potentially dangerous stimulant, but the combination of all of them together is particularly worrisome.

The Price and Quality of iQuzil

iQuzil is only available in free sample form through their website. Often this is an indicator that the product is a scam and that users are actually signing up for enrollment in a monthly renewal program, however that does not seem to be the case with iQuzil as they do not collect any sort of credit card or payment information.

There do not appear to be any sort of catches or hidden fees related to this offer. It is unclear what the reason for only offering free samples is, and it is possible that its practices and policies will change in the future.

Conclusion – Does iQuzil Work?

iQuzil does not have the ingredients profile that makes it seem like it could be an effective nootropic. None of their three primary ingredients are recommended by our panel of health and wellness experts for use in mental performance supplements.

Caffeine, vinpocetine, and adrafinil are all stimulants that have histories of being effective for fighting fatigue and little else. There are serious health concerns related to all three of these chemicals, and adrafinil has even been banned by several regulatory agencies.

There is no reason to think that iQuzil is an acceptable nootropic supplement. Our research team strongly encourages our readers to seek out other alternatives for cognitive enhancement.

The nootropic supplement that our experts agree is the most effective is Memotenz. It is a premium quality mental performance enhancement product that has been earning respect from customers and industry professionals alike.

Their blend is a high-potency array of the most effective nootropic ingredients on the market today. Click here to see everything that goes into Memotenz’s revolutionary formula.
