Alpha Brain is a significant dietary supplement manufactured by the world-renowned brand Onnit Labs. It has become one of the most popular natural products on the “smart drug” scene since it’s backed by rigorous clinical research & evidence.

The term “nootropic” was coined in 1972 by the psychologist & chemist Dr. Corneliu Giurgea, who uncovered & developed piracetam, the first synthetic “smart tab” in the world [1]. Based on Dr. Giurgea’s definition of a nootropic, it’s any natural or synthetic substance that can do the following:

  • ameliorate memory, concentration, attention span, & the ability to learn;
  • assist the brain function under distress & protect it from chemical & physical stress;
  • foster the efficacy of neuronal firing;
  • generate virtually zero negative effects & be non-toxic.

Alpha Brain meets the above definition perfectly. Indeed, it’s BSCG Certified Drug-Free® & is made using only natural substances that assist in supporting cognitive augmentation including concentration, mental speed, memory, and focus. Such rewards are the ultimate way to get “in the zone.”

Besides, the moment you ingest Alpha Brain, you can experience several benefits including:

  • 6+ hours of ameliorated mental processing, concentration & focus.
  • improved executive functioning and verbal memory & recall;
  • heightened “flow state” (perfect feeling of being “in the zone”).

In summary, if you’re searching for a robust natural nootropic, aside from modafinil, with virtually zero negative effects, then Alpha Brain should be your choice. It’s free from dairy, gluten, caffeine, nuts, & is keto-friendly (a low-carb diet).

Also, with Alpha Brain, you can easily recollect previous things such as names and places or activities, focus on complex tasks, reason more clearly if under stress, and react more quickly.

The outcomes of the study include the following benefits:

  • a 12 percent refinement in tasks of delayed verbal recall & executive functioning;
  • 21 percent faster completion time in executive function evaluations;
  • ameliorated recent verbal memory.
Overall, Alpha Brain is one of the few natural nootropic products in today’s society that has been scientifically demonstrated to work.

Alpha Brain Side Effects & Warnings

As stated by the manufacturer, Alpha Brain is the best nootropic ever made. However, there exist a few minor negative effects associated with this product that a user may experience.

This is chiefly if you want to use it while you’re nursing, pregnant, have or suspect a medical health condition, or are administering other meds. Nonetheless, presuming you are a healthy individual with the OK to use this nootropic, what can you anticipate?

When used at the advisable doses, they are all regarded as non-toxic and safe. However, that doesn’t mean there are no negative effects expected. How you respond to them depends on a host of factors including your physical condition, genetic factors, age, preexisting conditions, & whether you are taking any other meds.

Upping the dosage is not advisable & can eventually cause unwanted negative effects. Also, if you concurrently consume other supplements, e.g., caffeine, or ingest energy drinks with this nootropic product, you can get some negative effects.

  • nausea: To get rid of this symptom, take Alpha Brain with a light meal. This can deaden any feelings of nausea.

Besides, individuals prone to anxiety should be cautious about taking Alpha Brain or any nootropics.

Overall, the experience of the negative effects of this dietary supplement is rare. You shouldn’t have any issues if you stick to the advisable dose of 2 to 4 capsules per day after having consulted a physician.

Is Alpha Brain Overdose Possible?

Concerned about the outcome if you take too much of Alpha Brain? You shouldn’t have to worry. Since it’s a risk-free dietary supplement, it’s not intended to diagnose, prevent, treat, or cure any health problem.


However, it’s paramount to remember that some natural ingredients can give rise to severe negative effects when consumed in excessive quantities. This is particularly caffeine or similar products containing caffeine. Fortunately, Alpha Brain is absolutely free from caffeine & stimulants, so overdosing shouldn’t be a critical concern.

Alpha Brain Instant vs. Capsules

You’ve heard of the two, but what’s the difference between them? Alpha Brain Instant is also a dietary supplement that assists in supporting cognitive functions, including mental speed, memory, and focus, & helps with the “flow state.” Like Alpha Brain, it also contains the same ingredients in the same formula. The only difference is the time it takes to work. Original capsules take longer to kick in due to the time the body requires to break down the active ingredients & start to assimilate them. On the other hand, Alpha Brain Instant acts in the body much faster once ingested. It’s a fine powder that combines with water or any beverage & is assimilated through the lining of the stomach almost instantly. This product is great if you’re looking for an immediate “hit” or if you just don’t like the experience of swallowing capsules.

If eagerly seeking the ultimate dietary supplement that serves your brainpower needs instantly, Alpha Brain Instant is all you need.

Furthermore, Alpha Brain Instant is also available in a variety of tasty flavors that make it more enjoyable to consume. The maker offers this product flavored with ruby grapefruit, Meyer lemon, pineapple punch, blackberry lemonade, coconut lime, and peach. You can choose the one you prefer.

Modafinil vs. Alpha Brain

Modafinil & Alpha Brain are both nootropics. However, the latter is 100% natural as opposed to modafinil, which is a prescription-only med used to treat narcolepsy, jet lag, depression, shift work disorder, and obstructive sleep apnea, among other health conditions.

While both substances have similar beneficial effects in terms of ameliorating wakefulness, fostering concentration, & enhancing working memory, they are a world apart in terms of negative reactions & safety.

The famous “smart tab” is illegal to obtain without a physician’s prescription in most countries. On the other hand, Alpha Brain is a 100% legitimate dietary supplement that’s completely certified drug-free.

Undeniably, modafinil is a synthetic med that acts as a stimulant when ingested off-label by healthy humans. It massively ameliorates individual concentration, vigilance, focus, & alertness while giving a huge uplift in working & episodic memory [14]. Modafinil also provides huge refinements in emotion recognition as well as task-related motivation [15].

Generally, how does Alpha Brain compare with modafinil? Ideally, a dose of Alpha Brain awesomely rewards you with the following effects:

  • 6+ hours of ameliorated concentration & focus;
  • heightened verbal recall, memory, & executive functioning;
  • awesome mental processing;
  • intensified “flow state.”

On the other hand, the world’s most popular “smart tab” offers similar benefits:

  • 12+ hours of dramatically augmented attentiveness, vigilance, & alertness;
  • ameliorated focus & concentration;
  • improved learning experience;
  • optimized working memory [16];
  • ameliorated mental acuity.

In regard to cognitive benefits, Alpha Brain & modafinil are like night & day: the natural risk-free substances found in the former simply can’t compare to the latter in terms of efficacy, duration, & potency. In our opinion, modafinil takes the lead. Nonetheless, legal issues aside, there’s one great reason to prefer Alpha Brain to the “smart tab” – the adverse reactions.

Whereas Alpha Brain triggers very few to no negative symptoms in healthy individuals, the “smart tab” comes with a score of serious side effects that you should acquaint yourself with before using. According to a study, when modafinil is given to people who are non-narcoleptic, it brings about a whole host of negative effects including the following [17]:

  • headaches;
  • anxiety;
  • dyspepsia;
  • rhinitis;
  • nausea;
  • lumbago;
  • insomnia;
  • diarrhea;
  • vertigo.

Although these reported negative effects are mild, it’s necessary to know about them before deciding whether to take the “smart tab.”

Additionally, modafinil isn’t regarded as addictive. It contains no precursor molecules or substances known to bring about addiction. Nonetheless, it has been depicted to function as a reinforcer & have abuse potential under certain circumstances, particularly when used at a high dose. For example, in a case, a man with bipolar affective disorder developed the “smart tab” dependence & then had hypersexuality when he increased a dose from 400 to 1,000 mg/day [18].

So, if determined to acquaint yourself with the difference between Alpha Brain & the “smart tab,” that’s about that. Taking it in higher doses isn’t a pleasant choice with modafinil, although it doesn’t kill you.

Modafinil is indeed the ultimate nootropic because nothing matches its insanely great potency & effectiveness as the finest wakefulness-augmenting agent. Nonetheless, severe adverse effects it may cause shouldn’t be taken lightly, although researchers dubbed it the “world’s first safe smart tab.” Alpha Brain, on the other hand, provides a solid 4 up to 6 or so hours of laser-sharp focus & the power of concentration. It also heightens working memory with virtually zero negative effects.
