Alpha Brain Review

What if you could take a dietary supplement that would suddenly help increase your cognitive function, mental processing and give you an energy boost? This Alpha BRAIN review will help you decide if taking Alpha BRAIN is the right choice for you and your lifestyle.

About Alpha BRAIN

We all want something that can help protect brain functions, working memory, and cognitive performance for as long as possible.

Enter Onnit’s Alpha BRAIN, a nootropic dietary supplement designed to help you with cognitive function, memory, and focus. It is also designed to enhance your brain’s alpha waves and brain and nerve cells function.

If you are not familiar with nootropics, they are essentially cognitive enhancers— “smart drugs” that enhance cognitive functions, promote cellular integrity, improve mental speed, and help with executive functioning.

In the long term, this means that the effects of Alpha BRAIN can extend to several areas of life and activities. You will notice changes from workouts and work meetings to school projects, parties, and performances.

Sounds like a pretty good addition to your lifestyle, doesn’t it? Keep reading our Alpha BRAIN review to see if it lives up to the hype.

As a fun fact, Onnit is a company run by Aubrey Marcus (and backed by Joe Rogan).

What Is Alpha BRAIN?

Onnit’s Alpha BRAIN is one of the leading nootropics on the market. This brain supplement helps with focus, memory, and overall brain health.

As a certified drug-free product, Alpha BRAIN has tested safe when it comes to side effects and drug tests. This means that you can take the supplement anytime and feel confident that those random drug tests at your job will not be a concern.

Also, Alpha BRAIN contains no stimulants—so you should not have to worry about jitters, crashes, or interactions with coffee, tea, or energy drinks.

Onnit Labs states that it is perfectly fine if you are taking Alpha BRAIN along with coffee or caffeine because it stimulates your neurotransmitters directly and does not bog down your adrenal glands.

Taking the supplement is essentially like shifting your brain into the next gear, which sounds harmless and helpful.

Keep in mind too that Alpha BRAIN is formulated using ingredients that are backed by scientific research, like amino acid mixes and natural substances.

It is non-habit-forming, so there is no dependency concern or withdrawal if you do not take it. Check out this Alpha BRAIN review to further decide on what is right for you.

All You Need To Know About Alpha Brain Waves

Before we continue, it is relevant to tackle the topic of alpha waves and what that means for your brain.

When we talk about brain waves, we are referring to the phenomenon that occurs when brain cells, or neurons, use electricity to communicate with one another.

Some waves are slow, and some are fast, but alpha waves fall in the middle. This type of wave is often associated with a calm state of mind. Still, these tend to be produced less and less in the instant world we live in, but supplements can help.

That is why certain individuals prefer to use things like Alpha BRAIN instant mixed with the original Alpha BRAIN capsules to achieve more alpha waves. Ultimately, it can lead to improved cognitive abilities, effective neural communication, and even deeper sleep.

While many believe that a prescription-only drug is the only real method to obtain cognitive benefits and increased brain waves, Alpha BRAIN works in healthy adults without any added chemicals or pharmaceuticals.

Alpha BRAIN Ingredients

This supplement is vegan-friendly, caffeine-free, gluten-free. It also works thanks to a host of natural and non-GMO ingredients.

All of these are added at an optimal level to make sure that taking Alpha BRAIN will work for everyone.

Here is the official ingredient label for Alpha BRAIN capsules:

Alpha Brain Ingredients

Onnit Flow Blend

Amino Acids (L-Tyrosine, L-Theanine, and L-Leucine)

L-tyrosine boosts dopamine and working memory, improving your delayed verbal recall as well.

On the other hand, L-theanine reduces anxiety and depression and prevents and treats Alzheimer’s and ADHD. It improves mental performance and attention as well.

Finally, L-leucine boosts energy and metabolic functions.

Cat’s Claw Extract

Named for its claw-like thorns (which do scratch just like a cat’s claws!) This nutrient offers brain health benefits such as immune boosters and antioxidant effects.

It is a natural way to prevent inflammation in your brain cells that ultimately affect adequate cellular function.

Other side effects of this ingredient include nausea, vomiting, dizziness, headaches, and diarrhea.

Oat Straw Extract

The benefits of this extract include helping increase energy and mental clarity, reducing anxiety and depression, boosting cognitive functions, reducing inflammation, and improving performance in many areas.

Amazingly, there are no negative side effects of oat straw extract. Oats are nontoxic and neutral, and they help you accomplish tasks while improving your alpha brain wave production.

However, exceeding the recommended dosage may reduce cognitive enhancement benefits.

Onnit Focus Blend

Bacopa Monnieri

This is an herb that improves cognition, memory disorders, and anxiety. It is sometimes part of Ayurvedic medicine. That is where Alpha BRAIN gets some of its cognitive performance-enhancing and mood-boosting properties.

Possible side effects of this nutrient include nausea, stomach cramps, and digestive issues.

Alpha GPC

This is the main ingredient in this dietary supplement that is a precursor to the neurotransmitter acetylcholine.

The neurotransmitter acetylcholine is very important in the body and brain alpha wave production because it controls nerve cells, muscle cells, and hormonal glands.

Huperzine A

Without getting too much into the science of it, Huperzine A is a natural compound from the Huperzia Serrata plant.

It is also used to treat memory impairment and increase alertness. As a bonus, it can be part of the treatment of Alzheimer’s and other age-related memory conditions.

As for side effects, it seems that Huperzine A can cause nausea, vomiting, diarrhea, sweating, cramping, muscle twitching, and restlessness.

Vitamin B6

This company keeps the vitamin blend simple in their dietary supplements and only includes Vitamin B6 in the formulation.

Alpha BRAIN contains 10MG of Vitamin B6, which plays a role in neurotransmitter production in the human brain.

Onnit Fuel Blend


Last but not least, pterostilbene is the main antioxidant found in blueberries and other berries, almonds, and grape leaves. It is a chemical relative to resveratrol.

Antioxidants are always a good addition to your diet because they help reduce oxidative stress that often leads to inflammation. In the end, this damage can cause degenerative diseases and things like brain fog or memory loss.

Who Should Be Taking Alpha BRAIN?

Alpha BRAIN is ideal for students, athletes, executives, and those in the limelight.

This dietary supplement is also for those who have social anxiety, require mental concentration and focus at work, and that participate in competitions, performances, and shows.

While anyone can buy Alpha BRAIN, some may benefit more than others.

For example, those who need to complete complex tasks, who are at risk for a medical condition that involves cognitive decline, and who may undergo neuropsychological tests for work or study.

Even though baseline tests are not necessary, you can have them done to know exactly what supplement is for you.

Onnit Alpha BRAIN Benefits

The benefits of Onnit Alpha BRAIN are numerous. Alpha Brain helps overall brain function, including memory support, mood support, and brain support.

Memory Improvement

Many users cite improved memory and mental clarity, alertness, cognition, peak alpha brain waves, retention, and processing speed.

Do not expect a major memory improvement over a few days, but you should notice some effects over time.

Mood Improvement

Some have even reported improvement in anxiety or depression, which makes sense based on some of the ingredient benefits.

The ability to think faster and remember things better is probably Alpha BRAIN’s biggest positive.

Taking an alpha GPC supplement will provide you with an increase in acetylcholine, which can help promote calmness, relaxation, and help your mind achieve a flow state.

Cognitive Function

By helping increase your alpha brain’s waves, you will achieve better mental processing, cognitive functions, and overall effectiveness in nerve cells communications.

You can also try another Alpha BRAIN supplement, such as the Alpha BRAIN instant. These all contain the signature Onnit focus blend, flow blend, and alpha GPC to achieve superior results when it comes to cognitive function.

Downsides to Alpha BRAIN

So far, there seem to be no downsides to this brain supplement. However, you should be aware that nootropics and nutraceuticals are not cheap.

On the other hand, not everyone likes to take a pill or two a day, so it can be somewhat difficult to introduce it to your routine.

Does Alpha BRAIN Work?

Onnit’s claim that the supplement works after just a single dose can be backed up by several user testimonials. Still, you also have those who report nothing but adverse effects.

The third category is those who report no effects at all—positive or negative. Some say they had more vivid dreams but little or no alertness during the day.

It is worth mentioning that Onnit recommends giving the product at least two weeks before determining whether it is working for you or not.

Even if it may work instantly for some, everyone is different. It may be necessary to adjust the way you take it—with food and only one capsule at a time, etc.

Some individuals could benefit from taking the Alpha BRAIN instant too.

Various ingredients have been proven in clinical studies supported by placebo-controlled evidence.

Frequently Asked Questions

After posting our initial Alpha Brain review, we received a lot of questions about the product. Here are the answers to the most common questions.

Is Alpha Brain Legit?

Yes, Alpha Brain is legit. Additionally, Onnit Labs is a trustworthy company with a solid reputation.

As with any supplement, it is important to have realistic expectations too. This is not a “Limitless” pill. 

Accompany your supplement with better sleeping and eating habits, and manage the stress in your life. 

Should I Take Alpha BRAIN Every Day?

Onnit recommends taking two capsules of Alpha Brain daily, preferably after a light meal.

While taking the supplement every day should be safe, we find it more effective to take a couple of days off per week (the same goes for any nootropic).

For better results, check with your medical doctor or dietitian to ensure that two capsules are the right dose for you.

Is Alpha BRAIN Safe?

Yes, this nootropic is safe. However, since all supplements are not approved by the food and drug administration, they come with added risks.

Although Onnit states that Alpha BRAIN should have little to no side effects, some users have noticed problems.

Reported side effects include nausea, vomiting, diarrhea, cramping, headaches, light-headedness, dizziness, brain fog, weakness, fatigue, sweating, rapid heartbeat, insomnia, and tremors.

Nevertheless, these problems seem to only impact a minority of users, and the majority of customer reviews are favorable.

Trust The Alpha BRAIN Reviews

The users who reported positive effects love Alpha BRAIN. Many people state they notice improved moods, can focus better, and can remember more than ever before. Others say it is a definite game-changer.

Whether Alpha BRAIN truly works is largely up to each individual.

Nonetheless, if you know you are sensitive to medications and supplements, it is probably best to start with a smaller dose and increase gradually to test the effects.

Perhaps this is one supplement that some users have to adjust to, but there is only one way to find out for sure.
