However, it is worth keeping in mind that the effectiveness of nootropics will vary from person to person. They are not used to cure or treat any disorders, illnesses, or conditions. Moreover, it's advisable to consult with a healthcare professional before starting any new supplement.

Unveiling Alpha BRAIN ingredients

Alpha BRAIN contains three trademarked ingredient blends — meaning there is no information on the precise amount of individual ingredients. Below, we will provide a brief overview of these blends. Keep in mind that due to the lack of information regarding the exact amounts of active ingredients, evaluating the product's effectiveness becomes more challenging.

Onnit Flow Blend

According to the manufacturer's assertion, the objective of this blend is to promote alpha brain wave production

The blend consists of 4 components:

  • L-theanine. Linked to increased alpha brain wave activity, thus may promote relaxation.
  • L-tyrosine. May enhance cognitive function, especially during times of stress.
  • Phosphatidylserine. May be beneficial for memory and have neuroprotective properties.
  • Oat straw extract. Although the evidence is limited, oat straw extract is linked to improved working memory and multitasking.

Onnit Focus Blend

Focus blend aims to support the maintenance of optimal acetylcholine levels, a neurotransmitter crucial for various brain functions, including memory.

The focus blend features 3 ingredients:

  • Alpha-GPC. Acetylcholine precursor.
  • Huperzia serrata. A moss that contains Huperzine A which may help to maintain acetylcholine levels.
  • Bacopa monnieri. A herb that may influence acetylcholine levels.

Onnit Fuel Blend

According to the manufacturer, the fuel blend may promote brain health, contributing to optimal neural communication.

It is made from two ingredients:

  • Pterostilbene. May offer neuroprotective benefits due to its anti-inflammatory and antioxidant activity.
  • L-leucine. A branched-chain amino acid that may contribute to neuron regeneration.

How does Alpha BRAIN work?

Onnit suggests that Alpha BRAIN may enhance cognition through three key mechanisms targeting brain activity.

Promotes alpha brainwave production

Brainwaves occur when neurons in the brain send electrical signals to each other. Scientists distinguish 5 types of brainwaves; alpha waves falling in the middle of the spectrum. Moreover, alpha brainwave is associated with relaxed alertness, thus Alpha BRAIN may be

When it comes to the Alpha BRAIN supplement, it contains one active ingredient that has substantial scientific evidence supporting its ability to stimulate Alpha BRAIN waves: l-theanine. For this reason, the Alpha BRAIN supplement is often positioned as one of the best nootropics for anxiety.

Optimizes acetylcholine levels

Acetylcholine is a neurotransmitter that is involved in various functions within the central nervous system (e.g. memory) and the body (muscle movement). Low levels of acetylcholine are associated with memory issues.

Acetylcholine is not available as a supplement, however, there are a few substances that may help to optimize the levels of this neurotransmitter.

Alpha BRAIN includes four ingredients associated with acetylcholine levels: Alpha-GPC, Huperzia serrata, and Bacopa monnieri.


Certain substances in supplements and foods may have protective effects and help prevent brain cell deterioration.

In this Alpha BRAIN supplement, a few ingredients are associated with neuroprotection: Bacopa monnieri, l-leucine, phosphatidylserine, and pterostilbene.

For instance, pterostilbene possesses anti-inflammatory and antioxidant properties, meaning it may offer neuroprotective benefits.

How can Alpha BRAIN nootropics help you?

As Onnit suggests, Alpha BRAIN may offer a wide range of benefits. In the following section, we have delineated a select few of these benefits.

Improvement in memory

One of the most sought-after benefits of nootropic supplements is the enhancement of memory. Onnit Alpha BRAIN includes several ingredients known for their potential to support memory such as Bacopa monnieri, phosphatidylserine, and L-tyrosine.

Moreover, this nootropic may help to maintain optimal acetylcholine levels. As acetylcholine is crucial for memory, having optimal levels can potentially enhance memory.

Executive function support

The term executive functions refers to various cognitive abilities used to control and coordinate behaviors in oneself. These functions include tasks such as planning, organizing, focusing, multitasking, and adapting to new situations.

One clinical study on Alpha BRAIN has provided preliminary evidence suggesting that it may offer support for executive function.

Increased focus

Onnit Alpha BRAIN could be considered one of the best nootropics for studying as it contains a few active ingredients that may provide a boost in alertness and focus such as l-theanine, and L-tyrosine.

On the other hand, Alpha BRAIN does not contain caffeine and typically requires sustained use of the supplement to observe noticeable benefits.


Certain Alpha BRAIN ingredients may have neuroprotective benefits, including pterostilbene, l-leucine, Bacopa monnieri, and phosphatidylserine.

These neuroprotective properties could be valuable for individuals seeking long-term cognitive well-being.

Alpha BRAIN side effects and potential drawbacks

Although seen as generally safe, Alpha BRAIN can cause certain side effects. Below, we analyzed the most commonly reported side effects of this supplement. It is important to mention that as of now there are not enough clinical trials to know all the side effects of this particular product.

Upset stomach

Some individuals may experience an upset stomach when taking this nootropic. Some customer reviews have also mentioned more serious side effects such as nausea. To minimize the risk of such adverse effects, it is advisable to take Alpha BRAIN with a light meal.


Irritability is also one of the possible side effects associated with Onnit Alpha BRAIN. Some people may also experience restlessness.


Dizziness is also sometimes reported as a side effect of the Onnit Alpha BRAIN supplement. Moreover, some individuals may experience headaches as reported in the customer reviews.

If you experience any of these side effects, it is best to discontinue using the product and consult your primary healthcare provider.

Research behind Onnit supplements

With the increasing popularity of nootropics, researchers are paying more attention to certain ingredients within these products. However, research studies on commercially available supplements are not common. Consequently, the purported benefits of nootropic supplements are often described using the data extracted from studies that inspect individual active components.

Onnit stands as a company that features a few supplements that have been studied clinically — Alpha BRAIN being among them. Below we will present the data found in these studies.

The first study on Onnit Alpha BRAIN was conducted in 2016 and showed significant results regarding participants' cognitive function. Participants using this nootropic for 6 weeks showed improvement in verbal memory compared to the placebo group. Moreover, they scored higher than the placebo group in terms of executive function, which includes such mental processes as flexible thinking, information processing speed, and working memory. However, the study was relatively small, as it involved only 63 participants.

The later 2018 study on Alpha BRAIN showed no notable improvements in marksmanship performance among active-duty U.S. soldiers. This research spanned 31 days and involved 43 participants.

As there are only two studies on this nootropic supplement available, it is impossible to conclude its effectiveness. However, the data of the first study may implicate that Onnit Alpha BRAIN has the potential to improve performance on executive functioning and memory tasks. To fully understand the effectiveness of this product, more studies are needed.
