  • Improves alpha brain wave activity.

What is Alpha Brain?

Alpha Brain is one of the older and more established brands in the nootropic industry. It is primarily formulated from three proprietary Onnit blends. The main path of action is improving alpha brain wave activity and regulating the production of neurotransmitters. Alpha Brain promises improvements in thought processing speed, memory, focus and overall cognitive function. The end result is a state of mind that primes you to function at your best.

With over a million bottles sold, Alpha Brain has by default been subjected to years of extensive real world testing. It is therefore regularly recommended for people considering using a nootropic for the first time.

About the Brand

Alpha Brain is manufactured by Onnit Labs Inc, an Austin, TX-based company focused on formulating supplements for fitness, brain and general health. It is the name behind more than a dozen other products such as New Mood, Key Minerals and Total Gut Health. In April 2021, global consumer goods giant Unilever announced it had signed an agreement to acquire Onnit Labs.


Sharper Focus

You will find it difficult to achieve much if you cannot keep your mind fixated on a task for as long as is necessary to complete it. In fact, focus is essential for the attainment of all meaningful life goals including education, work, personal finance and family. History is replete with otherwise brilliant individuals that had a hard time getting ahead due a lack of goal focus. Alpha Brain’s ingredients improve task concentration without compromising your ability to multitask.

Faster Thought Processing Speed

How quickly you can interpret and react to information or a situation so important that it can sometimes be a matter of life or death. Think about an oncoming vehicle abruptly swerving into your lane. Apart from such hazardous circumstances, your speed of thought is essential to your ability to be effective at work, home and school. It’s what is sometimes referred to as thinking on your feet. Alpha Brain improves thought processing speed to help you quickly make the right decision the first time.

Improved Memory Recall

We keep diaries to remind us of important past, present and future events. Yet, diaries can only capture a tiny fraction of the information we absorb each day. Over time though, information can fade deeper into our memory and gradually become harder to recall. While this is a normal aspect of brain function, Alpha Brain can reduce forgetfulness and make it easier to remember important tidbits of information.

Does it Really Work?

Alpha Brain’s ingredients are clinically proven to deliver various improvements in cognitive health including memory, focus and thought processing speed. These benefits are made possible by the supplement’s ability to regulate neurotransmitter production and alpha brain wave activity.

Who Is Alpha Brain For?

Persons trying nootropics for the first time

Alpha Brain is one of the best-selling nootropics. Its large army of customers has inadvertently helped test it for safety and adverse reactions. If you are a first time user who is experimenting with nootropics, Alpha Brain is a good place to start.

Persons that are caffeine-sensitive

Caffeine is a relatively popular ingredient in brain supplements. But it has a major drawback – energy crashes. This and other adverse reactions can be especially uncomfortable for caffeine-sensitive individuals. Alpha Brain has no caffeine.

Persons struggling with anxiety

Anxiety is mentally debilitating. It makes it harder to invest your thoughts and energies on executing tasks. Alpha Brain’s ingredients are designed to fight off the jitters so you can have the calmness needed to do what is required.

Potential Side Effects

Frequently Asked Questions

How long before I see the results of using Alpha Brain?

The manufacturer does not provide a definitive timeline within which you can expect to see results. However, most nootropics that work for you will show some improvements within days of usage. It's best that you give it at least a month before you establish if it’s doing what it says it will do.

Can I use Alpha Brain with other nootropics?

No. Alpha Brain’s safety and efficacy has only been tested for its ingredients. There is no telling how it could affect your balance of brain chemicals as well as other biochemical processes if it’s used at the same time as another brain supplement. Also, nootropic products typically share some ingredients. Combining two products could exceed the recommended daily value for certain nutrients.

Does Alpha Brain contain any stimulants?

Alpha Brain does not contain caffeine or any other stimulant.
