Alpha Brain Review – A Full Analysis

Alpha Brain is one of the most famous nootropic blends that sparked debate and controversy in many communities. Produced by Onnit Labs since 2010, Alpha Brain has been featured in a variety of media outlets including the Joe Rogan Experience. Many nootropics users question the validity, price, and efficacy of Alpha Brain for cognitive enhancement, but few provide a full analysis of their complaints, biases, and / or compliments.

In this Alpha Brain review, we will discuss every conceivable aspect of this nootropic blend in order to help you determine whether it is worthwhile for purchase. Our perspective is unique because Pure Nootropics is itself a nootropics company, but we do not actively sell a similar blend of products.

Before diving in to what is a very long read and analysis, we will first provide our conclusion:

Alpha Brain can be an effective tool for improving cognitive abilities in some individuals, but like most nootropics is highly individualized. The synergy between vinpocetine, huperzia serrata, and 100 mg of alpha GPC is definitely effective for improving cholinergic functioning, but more noticeably for those lacking choline-rich diets.

While some ingredients (such as bacopa monniera) are not provided in high enough doses, others (like L-theanine) can provide useful psychoactive and cognitive effects. There seem to be relatively few Alpha Brain side effects, but this is highly dependent upon the individual.

Recent Alpha Brain studies show promise, but also raise certain questions about efficacy. Finally, the cost may be prohibitive for some, but finding the ingredients and putting them all together is a lot of time and effort that Onnit Labs saves with their product. Price is always a function of the market so there is obviously demand at the current price point.

Does Alpha Brain Work?

Anyone searching for an Alpha Brain review would be interested to know whether the nootropic blend “works”. Of course, as anyone in the nootropics community will tell you: it depends. There are many factors that will influence whether Alpha Brain works for you.

People that maintain a diet consisting primarily of fruits, large volumes of vegetables, healthy fats, and protein will probably consume enough choline that reduces the effects of Alpha Brain. Getting adequate sleep, exercising, and general healthy lifestyle habits will also make the cognitive enhancement of Alpha Brain less effective. This does not mean that you will not see any advantages of using Alpha Brain if you maintain these practices, but the likelihood that it will be life changing is slim.

For those who are too busy with familial, professional, or educational responsibilities to maintain healthy eating, sleeping, and lifestyle habits, Alpha Brain can be incredibly effective. Many people overlook the 10 mg of B6, which can be an effective nutrient for 20 – 40% of the population. While the source of the B6 is unknown, assuming it is a somewhat bioavailable source, it can be helpful if absent from diet.

Adequate Vit B6 intake by state

The benefits of Alpha Brain are manifold, but they come in varying magnitudes and combinations depending on the individual.

For example, 200 mg of L-theanine is an effective dose with this amino acid. Research shows that L-theanine can cross the blood-brain barrier relatively easily and has the potential to increase brain dopamine and possibly serotonin. Several studies using EEG showed that lower doses of L-theanine improved alpha brain wave levels, which is associated with relaxation.

There are also a plethora of studies about L-theanine’s efficacy for improving mental energy and alertness. The same EEG study concluded that L-theanine “…has a significant effect on the general state of mental alertness or arousal…alpha activity is known to play an important role in critical aspects of attention…” Other studies on kids with ADD showed that L-theanine improved sleep quality and improved attention the next day.

On the memory side, there can be substantial Alpha Brain benefits as well. Vegetarians or individuals who have low choline[1] will benefit even more as they may be deficient. Dietary choline is the precursor for acetylcholine, which has a number of functions, but does help memory function as well.

Alpha Brain works through two methods to improve acetylcholine in the brain; the first is to provide raw choline through alpha GPC, which is arguably the best choline source (definitely top 2). The second step is providing acetylcholinerase inhibitors (through huperzia serrata), which do not allow acetylcholine to be degraded.

The enhanced acetylcholine can also improve the lucidity (control) and vivid nature of dreams. In theory, the huperzine and alpha GPC causes the intense vivid nature of dreams. Perusing internet forums and communities like Reddit yields much discussion about Alpha Brain’s potency for lucid dreaming. The overall attitude seems to be of awe and surprise at the efficacy, but some recount “terrifying nightmares”. Considering scientists know little about dreams, each individual will probably have a different experience.

What’s the Hype?

Despite adequate doses of many ingredients, there are plenty of weak points. The most glaring is the use of bacopa monniera, which is one of the most effective Ayurvedic compounds found on the Indian subcontinent. As a fat soluble nootropic, it is interesting that Onnit does not recommend taking Alpha Brain with a fat source of some sort. On an empty stomach, bacopa monniera would not be well absorbed. Furthermore, the 100 mg dose is far too small to provide any real results.

While there is plenty of evidence suggestion bacopa improves cognition, the amount and administration makes a significant difference. For anyone particularly thrilled with Alpha Brain due to the bacopa, it might be a better idea to supplement with straight bacopa monniera instead.

Another ingredient with questionable psychoactive effects is AC-11, which is a patented extract of Cat’s claw (uncaria tomentosa). It is impossible to know whether AC-11 has the correct amount of carboxyl alkyl esters to be effective. There is very little research indicating that the extract is anything more than an antioxidant one might get from eating blueberries or dark chocolate.

Is it Safe? Alpha Brain Side Effects

Any time one alters brain chemistry, a fair bit of skepticism can go a long way. Most custom blended nootropics are rather tame compared to experimental compounds like dihexa or sunifram. Some individuals dominant in acetylcholine may have headaches or pressure around their jaw due to the excess neurotransmitter. As mentioned earlier, there are a few cases where dreams become too vivid for comfort.

The current formulation of Alpha Brain uses mostly ingredients that are recognized as safe by the FDA. Combined, there is no way of knowing whether effects can be magnified or become dangerous. However, an overview of each ingredient and the dose can help one understand potential Alpha Brain side effects.

  • B6 (10 mg) – This is just a nutrient. No reason to believe it is bad, though no telling how much is bioavailable.
  • Alpha GPC (100 mg) – This is generally regarded as safe (GRAS) by the FDA. Toxicity shows it is a very safe ingredient.
  • Huperzia serrata (40 mg) – The active ingredient is Huperzine A, which is discussed with some caution. Assuming 1% huperzine A, the 40 mg of huperzia serrata is about 400 mcg, which can be double the recommended dosage. This high dosage is probably to blame for the vivid dreams and may be the only thing to watch out for.
  • Vinpocetine (5 mg) – At 5 mg, vinpocetine is not a dangerous ingredient. It is half the recommended dose, but when combined with other nootropics, it is probably as much as one needs. People with low blood pressure may want to be careful with vinpocetine, but again it is at a low dosage.
  • AC-11 (350 mg) – Seems quite safe though studies are lacking. At a glance, it has antioxidant properties, which are typically (though not always) useful.
  • Phosphatidylserine (50 mg) – Well researched and relatively safe ingredient at a low dose. Not much to worry about.
  • Bacopa (100 mg) – Used for centuries. Safe with plenty of research.
  • Pterostilbene (750 mcg) – This is a relatively new compound with a dosage that exceeds that of a 250 pound person. Given the lack of research and high dose, it is interesting, though probably not threatening.
  • L-tyrosine (300 mg) – Well researched and dosed low, so there is little to worry about.
  • L-theanine (200 mg) – Incredibly safe ingredient with a lot of research. Nothing to worry about.
  • Oat straw (100 mg) – Mostly a filler. Nothing to worry about.

In general, Alpha Brain should be recognized as safe, but it will always vary depending on the individual. Much respect must go to Onnit Labs for providing the formula for anyone interested in the exact doses and ingredients.

Most of the supplement and nootropic industry does not do this to the detriment of users and the community. Onnit has been more than forthcoming about the ingredients while trying to balance the business aspects of a unique blend.

Cost Review of Alpha Brain

No matter how good a nootropic is, price is always a main factor. People want something for nothing and complaints about Onnit and Alpha Brain abound. For a month’s supply it would require buying two bottles totaling  $59.41 (taking two capsules per day). Expensive? Yes. But here are a few things to think about.

1. Onnit’s money back guarantee – Pure Nootropics derived the money back guarantee from Onnit Labs. They are one of the first and only nootropic / supplement companies that provides such a feature. If you try it and find out that it doesn’t work, just return it. It’s a major company with plenty of influential people backing it; they aren’t going out of business anytime soon and they will not scam you. Worst case scenario you try something out and it doesn’t help, but doesn’t cost you anything.

2. Assembling the ingredients is a pain – There are some diehard nootropic fans that will buy each individual ingredient and try every new research compound. For people that do not know where to buy safe bulk nootropics and don’t have the patience to take them all together, Alpha Brain is priced for convenience. If you are looking for cognitive enhancement, there is a good chance you don’t want to be spending all your day filling capsules or taking poor tasting drinks. Most likely you want to be better in the gym, work harder on your business, etc.

3. Nobody is forcing you to purchase Onnit Labs, Aubrey Marcus, and Joe Rogan are not trying to force you to buy anything. They want you to, but you can vote whether it is too expensive with your wallet. Just don’t buy. Why get offended at the price if you perceive it is “outrageous”?

Alpha Brain Interactions with Other Nootropics

While Alpha Brain is full of different ingredients, adding other nootropics in a “stack” can be an effective method of using the supplement.  Pure Nootropics may be biased, but racetam products work particularly well with Alpha Brain. Studies of piracetam show that choline exponentially improves cognitive enhancement. Racetams typically increase utilization and uptake of acetylcholine into certain regions of the brain (such as the hippocampus).

Alpha Brain works primarily on the cholinergic system through alpha GPC choline and a high dose of Huperzia serrata. By enhancing acetylcholine with Alpha Brain, one can get a full effect by taking piracetam or other analogues. Anecdotally, nootropics users have found great use with phenylpiracetam and pramiracetam as well.

Piracetam and choline combined were far more effective than either ingredient alone

Adding many nootropics together should always be done with caution. While Alpha Brain utilizes many ingredients, it is recognized as safe. Combining it with other racetams may have differing effects.

Alpha Brain Studies

Unlike most other nootropic companies, Onnit has spent considerable resources testing Alpha Brain. While only a pilot study is currently available, the evidence is promising in a number of cognitive categories. Nonetheless, trained scientists / researchers and doctors have made interesting points about the enhancer and efficacy studies.

One particularly poignant point came from a (unverified) MD and (soon) PhD in oncology. Essentially, one complaint focuses on the 19 neuropsychological tests, which did not require much to be considered significant. Second, he argued that significant differences between groups was used rather than between baseline and intervention. An Onnit representative’s response can be found here and the doctor’s final word here.[2]

Discrepancies in the Onnit study are evident, but hopefully the feedback from professionals will help improve the larger studies of Alpha Brain products. Considering no other supplement company is testing in such a way, it is refreshing to see engagement from Onnit and the nootropic / scientific communities.

Personal Experiences – My Alpha Brain Review

Personal opinions and experiences matter little in the scheme of things. From a scientific perspective, it is not as encompassing as the studies done in a lab setting. Nonetheless, no Alpha Brain review would be complete without adequate information about personal experiences and usage.

Given my diet and other lifestyle factors, I was skeptical whether Alpha Brain could help improve cognitive enhancement too much. Just analyzing the ingredients was enough to tell me that it was nothing really special. When I started to use the Alpha Brain, I was a bit shocked by the marked difference. The primary enhancement came with mood, which was greatly enhanced after using Alpha Brain.

I never took Alpha Brain late enough to recount vivid dreams, but other Alpha Brain reviews and anecdotes indicate it is a frequent occurrence. The mood improvement alone was useful enough to recommend the product for anyone looking for a simple and convenient way of improving cognition. While I may not always have the spare cash to purchase the nootropics, those that are capable should do so for sure. With a money back guarantee there is no reason not to.


Many of the individual ingredients that comprise Alpha Brain can be found in our Shop. We offer capsules on many different nootropics, allowing users to can create their own custom stack.


[1] It is impossible to accurately detect whether you have adequate or low choline. However, knowledgeable scientists / doctors have developed tests to find out. Use the Braverman test to see whether you are dominant or deficient in choline, which could help you review Alpha Brain for yourself.

[2] Whether the “dARKsURGEON” on Reddit is an actual MD or PhD is unverified. His argument does make sense and seems to point towards some glaring faults with the preliminary study. While I would always err on the side of caution, it is definitely not definitive proof that Alpha Brain is an effective cognitive enhancer. I believe Aubrey Marcus and Joe Rogan will try to address them if noticed.

    Awesome review, but was wondering at what times did you take your two pills a day? Is there a recommended time between dosage?

    I’m asking because I just got my first bottle, I’m over 200 ilbs and struggling to figure out the correct dose and time. I know I can take up to 3 in a 24 hour period so I was thinking of taking 1 when I get to work around 11:00 am, then another when I get home around 5:00 pm and 1 more before bed at 1 am in the morning.

    Does this sound good or would you recommend just two pills a day? Any advice

    • PureNootropics says:

      Hi Josh,

      Thanks for your comment. Individual needs will vary, and honestly the ingredients are not too harmful to the point where you will experience major adverse effects from taking too much, but you need to monitor your mind, body, and mood. Your spacing out of the pills may be adequate for you (cost may also be a consideration when taking 3 capsules/day). With many nootropics there is generally an inverted bell curve with regard to efficacy, where too much of something reduces the nootropic benefit. The ultimately requires that dosing be adjusted to get the optimal effect; The problem is that the optimal dose for a particular compound will differ from person to person.

      Stacks like Alpha Brain, that contain an assortment of different brain vitamins (so to speak, many of which I’m a big fan of), do not give individuals the ability to test their reaction to the particular ingredients, instead its meant to be more of a “one size fits all” cognitive enhancer.

  2. Mansal Denton says:

    Wow, this is an amazing review of a supplement I’ve heard about so many times on the Joe Rogan podcast! Thanks for getting it up.

    I also found there is a lot of individuality when it comes to Alpha Brain. Some people can take 1 capsule and feel a lot of effects while others can’t feel anything after taking 2 or 3. It really depends on the person sometimes.

  3. Rene Volpi says:

    I’ve been consuming Alpha Brain for about a month now with remarkable results. Having bought the supplements individually, I’ve noticed a sharp, mood-enhanced state which has turned my life around substantially. The difference on my disposition is quite noticeable, and my overall attitude has received high marks as well by friends and family. Being a vegetarian, I am well aware of the importance of maintaining a healthy life-style as much as possible, with my efforts concentrating on also keeping up with exercise, a good diet and a dose of proteins and other supplements like B-6, B-12, Omega-3’s, folate, etc.
    In this day and age, with stress being the root cause of much conflict and unsettled mind activity, most people intuitively know there is no magic bullet or pill that can take the place or remotely act as a cure for all which ail us. This supplements, however, in conjunction with a healthy life-style has turned my daily activities from an almost catatonic and quite semi-depressive state into much the opposite to which I am highly thankful for. My two cents on the subject. I hope my contribution here have managed to help someone.

  4. Dobrusia says:

    Hi guys,
    I’m wondering why the ingredient listed in Onnit website are different to here? Their ingredients have ‘blends’ where is here are individual ingredient dosages?

    • PureNootropics says:

      Onnit has almost certainly adjusted the amounts of particular ingredients in its flagship product reviewed here. Alpha Brain ingredients were listed at one point, but now the ingredients make up a blend or several blends, as you note, that obscures the quantities of ingredients contained (note that ingredients must be listed in order of highest to lowest in terms of quantity).

  5. Brett ladrech says:

    Hi guys, I’ve been taking Alpha Brain for 15 days straight, while maintaining my regular diet which is for the most part healthy. I’ve noticed that I’m gaining weight since taking the pills, which is unusual for me since I have a fairly fast metabolism. Has anybody else experienced this?

    Thank you,

  6. Bill Adams says:

    Hello. I’m an older guy, about 64 years old and I am lucky enough to be saddled with 13 or so different medications for several medical issues that I currently enjoy. My main question is, should I worry about whether or not Alpha Brain interacts with any of my medications. I would like to improve my mental reflexes and response, but of course, not at the risk of a negative interaction with my meds. Do I have anything to worry about?

  7. Alicia says:

    I love how it makes me feel. I’ve been so much more motivated, clearheaded, inspired and disciplined with the use of this supplemment. If I take two pills together experience nausea and my cognition overloaded and overstimulated in a slightly overwhelming and distracted manner. So I take one pill in the morning and another one as needed in the late afternoon, especially if I plan to work creatively throughout the evening. With my busy work schedule this has greatly supported my other interests and learning, whilst before I would too often feel drained, distracted or disinterested in my passions, putting ideas off and engaging in many unproductive activities. I also noticed I have gained weight. I gained about 5 lbs since I started taking it about 2 months ago. It troubles me to notice that. My weight has been the same for a decade, and the only time it went up I associated it with depression I had at the time. I am petite but I wouldn’t say skinny, so the extra few pounds are definitely unwelcome. I would like to find out what causes this side effect.
