Alpha Brain

What is Alpha Brain?

Alpha Brain is a dietary supplement that helps support cognitive functions, including memory, mental speed, and concentration. When tested on a control group of ages 18-35 for a six week period, significant cognitive improvements were recorded. Yes, this product really works!

2016 was the year I first heard about Alpha Brain. It immediately caught my attention after reading through the ingredients and reviews of many competing supplements. Out of the available nootropics, it stood out as the best nootropic for memory and focus. It is backed by clinical results, and it also has the benefit of many professional recommendations.

Alpha Brain’s founder stated that it would start working the first time the user takes a dose. I wanted to see if his claim was accurate as nootropics rarely work the first time. I ordered a 90ct pack and kept notes for a review while taking this product.

Here’s my review of what happened:

Week One

A week before beginning my Alpha Brain regimen, I moved away from other nootropics. At breakfast on the first day of the test, I had two capsules as per the directions.

My ability to concentrate improved a bit only half an hour after the capsules were taken. I had quite a bit more energy without any noticeable mood changes, for one, and I definitely felt more capable of getting my day started productively. After a couple of hours, the focus boost was gone. My motivation seemed to improve some during the focus boost, and I found it easier to get my work done.

The first day’s results were fine, and I continued taking two capsules each day after. Like with the first day, some doses were done with breakfast, but I also took some with no food at all. The results were about the same as they were on the first day, with a focus boost, a little increase in motivation, and slightly more energy.

Week Two

I continued another week of taking the capsules, and the results remained the same. I even added another capsule to my daily dose, but there wasn’t much of an additional effect. It seemed as if the results were better when only two capsules were used.

Although some of my team members had issues with the capsules, there were no noticeable side effects (below you can see more information about the side effects). Overall, my experience with the nootropic supplement was pleasant and the product was definitely helpful.

It was clear to me that there were some benefits to taking Alpha Brain during my review phase. Your concentration and processing speed will definitely improve, and your memory and mood may be better.

Compared to other nootropic supplements, is it a better option? What side effects come with taking Alpha Brain by Onnit?

Different Blends of Alpha Brain

Alpha Brain is one overall product, but there are different blends of this product for different components of brain health. One option may focus on heightening alpha waves while another helps you to concentrate more directly on tasks. See the different options below:

Onnit Flow Blend, 650 mg

This is a great option for those looking to heighten the brain’s natural production of alpha waves. Alpha waves put you into a flow state, which help you to naturally relax and focus, making day-to-day tasks easier and more enjoyable. The following nootropics can be found in the Flow Blend:


Cognition improvement while acute stressors are active has been shown under L-Tyrosine, an amino acid. Well being and working memory also gain positive effects from the presence of this active. People who are in stressful environments will especially notice the potency of L-Tyrosine.

Oat straw extract

The benefits that oat straw provides are thought to be improvements on cognition. While benefits are mostly anecdotal as there aren’t enough studies to confirm them, oat straw may cause a boost in brain functionality, cause a reduction in inflammation, and act as a mood enhancer.


Commonly found in green teas, L-Theanine aids in relaxation, making people more alert while keeping their stress levels down. When combined with caffeine, the effects of this nootropic will be felt along with the caffeine’s effects.

Vitamin B6

The body produces an important coenzyme with Vitamin B6, a B-vitamin. Although it carries benefits and is necessary in the body, any special reasons to use this particular supplement within a nootropic isn’t really noticeable, however, it does help by providing the body with natural energy.

Cat’s Claw Extract

A vine that fights against fatigue and inflammation, Uncaria Tomentosa, otherwise known as Cat’s Claw, comes from the Amazon. Cat’s claw is found within many natural supplements and has a multitude of uses in homeopathic medicine.


Cognitive function is dependent on Phosphatidylserine. Normally it’s made within the body, but cognitive capabilities and memory can be improved when it’s taken as a supplement. Any decreases in cognitive function can be slowed down with this powerful amino acid.

Focus Blend, 240 mg

The Focus Blend allows the brain to be receptive to acetylcholine, which is important f you’re considering nerve health, muscle health, and hormonal gland health.

Alpha GPC

This supplement contains choline and is popular among both older and younger people. It decreases the decline in cognition in older people, and it improves memory for all ages. It’s also popular among athletes who want to see their power output increase. Acetylcholine is known to have Alpha GPC as a precursor.

Bacopa Monnieri extract

An adaptogen herb that has a lot of popularity behind it, Bacopa Monnieri extract is very effective nootropic. It improves cognition while boosting memory and deceasing anxiety.

Huperzine-A (Huperzia Serrata)

Acetylcholine is an enzyme that can cause degradation in the learning neurotransmitter, and Huperzine-A can inhibit it, leading to an enhancement of cognitive abilities. An increase occurs as a result of this inhibition. As a cholinergic nootropic, Huperzine-A shows usefulness in helping the elderly fight cognitive decline. There may need to be some cycling with it.

Onnit Fuel Blend, 65 mg

This is the best blend if you’re wanting to heighten the way your neurotransmitters communicate.


Used for cognitive improvement, Pterostilbene, a methylated stilbene molecule, can also be used for the reduction of glucose and cholesterol.


L-Leucine is unique in that it isn’t a typical nootropic, but rather the primary BCAA. BBCA mixes can be used to obtain L-Leucine, however it’s benefits can still be achieved as a supplement, and it may cost less.


Found in the periwinkle plant is the alkaloid Vinpocetine, which is a well known nootropic that improves cognitive abilities.

The brain’s blood flow is often thought to be increased when Vinpocetine is taken.

What is the Alpha Brain Dosage?

Onnit recommends taking two capsules of Alpha Brain each day. I wouldn’t recommend a dosage higher than this, as the compound amounts of the supplement aren’t known. Following the recommended Alpha Brain dosage will prevent the chances of any negative Alpha Brain side effects.

Alpha Brain should be taken before or with breakfast.

What Are the Benefits of Alpha Brain?

Concentration, mental speed, memory, and other brain functions are all supported when you take Alpha Brain. Your productivity and cognitive performance will improve by taking the pills.

Alpha Brain’s effects will last around four hours, according to my own experience with it. However, it’s important to take it consistently so you can notice the long-term effects of this mental performance supplement.

What Are the Side Effects of Alpha Brain?

Many users have reported feeling a few side effects after taking the Alpha Brain supplement.

Alpha Brain is generally thought of as being one of the safest nootropics to use. Some users have made reports about headaches and stomach problems while taking the supplement, but during the course of my trial, I took the normal dosage and didn’t feel any side effects. Headaches and some brain fog have been experienced by people on my team.

The chances of most people experiencing side effects is low based on what I’ve researched. Stop taking the supplement if you do experience any problems or stress from the supplement.

Will I Build A Tolerance to Alpha Brain?

Signs of a tolerance hasn’t been supported by any evidence, and Onnit recommends taking the same dosage each day, so you most likely do not build a tolerance. There is some cycling that needs to be done with some of the ingredients. Five days on and two days off is generally what I use. The risks of using it are lowered with this method.

The effectiveness of Alpha Brain is supported by clinical studies, which led me to believe that the reviews would be glowing. Some digging will bring up user reports about side effects they’ve been experiencing. Precaution must be taken when taking any new supplement.

Where Can Alpha Brain Be Purchased?

Alpha Brain can be purchased here on the official website.

You can get a 60ct of Alpha Brain for $50, but if you order more or less, the price can vary. Be sure to purchase from a legitimate retailer, or purchase directly from the site so you can be sure that you’re getting the legitimate product.


Many users have given Alpha Brain great feedback and raving reviews, and it delivers results that have been clinically proven for aiding overall mental health and function. In this Alpha Brain review, I described the many benefits you will notice as well as the cautions you need to take when trying out a new performance supplement. There are a few different blends depending on which one you think will work best for your needs, but there is definitely a great option for you among the different blends. I definitely noticed positive changes when I took Alpha Brain myself.
