In this iQ2 supplement review, we will cover the basics of iQ2. iQ2 is a dietary supplement that provides nootropic effects. A nootropic supplement enhances cognitive function in one or more ways. Nootropics have become very popular, among the nootropic products are Mind Lab Pro, NeuroIGNITE, and Apex Mastermind. Nootropics can enhance memory, executive functioning, creativity, concentration, and focus. They are not intended to treat conditions or diseases; they are intended to be used by healthy individuals to enhance cognitive function in order to give them an edge in school or at work. 

Benefits of iQ2


iQ2 is a multi-functional nootropic, meaning it enhances many different aspects of cognitive functioning. In addition, it has other healthy effects; many users report experiencing loss of unwanted body fat and reductions in food cravings. In addition, it improves blood flow throughout the body and brain, reducing the risk of developing cardiovascular diseases. In terms of cognitive enhancement, iQ2 offers the following benefits:

  • Memory enhancement that leads to never forgetting important things on your “to do” list and that accelerates learning. These effects lead to improved productivity, academic success, and impressive performance at work.
  • Focus and clarity. Instead of being slow, fatigued, and confused, you will be able to focus and concentrate on the issue at hand.
  • Faster and more efficient brain function. Quickly grasp new concepts and experience enhanced creativity and speed during problem-solving. 

Ingredients in iQ2

iQ2 comes as capsules. The instructions say to take two immediately after wakening every morning, preferably on an empty stomach. And additional one or two capsules may be taken in the afternoon or evening for a quick pick-me-up. The ingredients in iQ2 include:

B vitamins

B vitamins are essential for brain function. iQ2 provides B6, B12, folic acid, and panthothenic acid. B vitamins are water-soluble compounds essential for normal metabolism; they are not stored in significant amounts in the body and need to be consumed on a regular basis.

B6 is essential for brain development and function. Vitamin B6 deficiency can lead to depression, confusion, and fatigue. B6 is found in poultry, fish, and potatoes, among other foods, but many people do not consume enough in their diet, leading to sub-optimal brain function.

B12 is a essential for many functions of the body, in particular brain function. Vitamin B12 deficiency can lead to cognitive impairment and even overt dementia. It is only found in foods from animal origin, and thus it is not uncommon for vegetarians and vegans to be become deficient. In addition, many older people lose the ability to readily absorb this vitamin through the intestine, and thus although they may consume a sufficient amount of the vitamin, only a small amount enters their body.

Folic acid (sometimes called vitamin B9) is primarily involved in DNA synthesis and the division of cells. It has received public attention because a deficiency of folic acid in early pregnancy leads to abnormal development of the brain and spine, causing spina bifida. In adults, deficiency of folic aid manifests as anemia and severe fatigue. It is abundantly found in fresh dark leafy greens and has been added to wheat products as a supplement, but many individuals who avoid eating wheat and also don’t consume fresh greens very often are somewhat deficient in this vitamin that is essential for brain health.

Panthothenic acid (sometimes called vitamin B5) is primarily involved in the synthesis of coenzyme A, a cofactor involved in a variety of basic, essential metabolic processes. Although abundant in a variety of fresh foods, processing foods can dramatically reduce its concentration by up to 80%. Panthothenic acid deficiency results in restlessness, irritability, headache, fatigue, and difficulty sleeping; severe deficiency can cause nerve damage. Very rarely, individuals are born with an inability to use panthothenic acid and these children experience abnormal nervous system development followed by neurodegeneration and death, highlighting the importance of this vitamin in brain function. 


Choline is sometimes considered to be a B vitamin. It is extremely important for nervous system function and like folic acid, deficiencies during early pregnancy can lead to spina bifida. Although it is synthesized by the body, the amounts made may not be sufficient to support optimal brain function.


Reactive oxygen radicals are by-products of natural metabolism. Excessive production of reactive oxygen radicals can cause extensive damage to cells, and this type of damage to neurons in the brain may be involved in the progressive memory loss and the reduced cognitive function many people experience as they get older. iQ2 provides a rich cocktail of antioxidants in the form of raw cacao powder. This natural product created from cacao beans is also a rich source of tryptophan, which is the raw material for the neurotransmitter serotonin, which is necessary for reducing anxiety and depression and producing a calm, focused mental state. 

Natural stimulants

Guarana seed extract is included to provide a natural energy boost and to relieve fatigue. 

Acetylcholine boosters

DMAE and huperzine-A are ingredients in iQ2. Huperzine-A can be found in many nootropic products, like Genius Consciousness. Both Huperzine-A and DMAE boost production of the neurotransmitter acetylcholine. This neurotransmitter is essential for memory and learning, and at one point in time DMAE was a popular treatment for children with learning disorders. These two ingredients have also been used as treatments for patients with dementia-related memory disorders. 

Does iQ2 work?


The many users of iQ2 report it works very well, just as advertised. An examination of the ingredients of iQ2, as provided in this iQ2 review, suggests it should be quite effective. Studies of the individual ingredients agree that this nootropic should indeed work well for improving memory, focus, and clarity. iQ2 provides all of the key vitamins and nutrients the brain needs for optimal function. One of its unique features not found in most other available nootropics is the raw cacao powder, which contains over 700 natural and beneficial ingredients. A clinical study conducted at Columbia found that consumption of cacao powder noticeably improved the memory of every single participant. 

Who should take iQ2?


iQ2 is intended for anyone involved in mentally taxing activities looking for a natural edge-namely, students and professionals. It is not intended for use by individuals with medical conditions such as dementia or learning disorders, although it is possible it may be beneficial for such individuals. The effects of iQ2 on children under the age of 18 and on developing fetuses and infants are unknown, and thus only adults who are not pregnant or breastfeeding should take iQ2.

Safety and side effects

Since all of the ingredients found in iQ2 are fully natural compounds derived from natural sources, it is considered to be extremely safe when taken as directed. Its ingredients are natural vitamins and nutrients the body needs and have been declared by the FDA as GRAS (generally recognized as safe). iQ2 is prepared in FDA-approved cGMP facilities within the US and is therefore guaranteed to be free from impurities.

Most users report no side effects. Occasionally, a user will report some mild queasiness the first few days of use that then goes away with continued use. 

Where to buy iQ2

iQ2 can be directly ordered from the manufacturer, iQ2 labs. A monthly supply costs around $50, although buying it in larger amounts at one time can significantly reduce the cost.

In conclusion

In conclusion, in this iQ2 review, we have found that iQ2 is a safe and effective nootropic appropriate for use by adult students and professionals looking for that mental edge to help them get ahead.
