Alpha Brain: The Cognitive Performance Booster

In today’s highly competitive world, we are all looking for a way to get ahead of the rat race. But, we cannot do so unless our brain is functioning at its best. Whether in academics or the corporate world, our cognitive abilities are constantly being tested and challenged. Staying alert and focused isn’t always easy.

There is good news, however, after years of research into brain supplements that can enhance cognitive functioning, Onnit Labs launched Alpha Brain in 2010. Within a very short span of time, Alpha Brain has been able to gather numerous positive customer reviews to become one of the top brain supplements in the market today.

Before Alpha Brain entered the market, nootropic supplements were largely an underground phenomenon. But, with the help of good customer reviews and amazing marketing efforts, such supplements have become much more mainstream.

According to Onnit Labs, Alpha Brain improves the ability to remember names and places. They also claim that it enhances the ability to focus on complex tasks, increases mental speed in response to stimuli and sharpens overall concentration.

Apart from being the leader in nootropic supplements, Onnit Labs offers supplements for a variety of other needs as well, such as power foods, proteins and performance enhancing foods. However, before you choose Alpha Brain supplement or any other Onnit nootropics, check their dosage & side effects & learn how does it work.


According to Onnit Labs, Alpha Brain is made of natural ingredients that are proven to enhance cognitive functioning, such as:


L-Tyrosine has been found to enhance mental performance during periods of distraction and extreme stress, such as loud noises, exposure to cold and sleep deprivation. It also improves memory and mood.


Theanine is an amino acid, found in high quantities in the leaves of green tea. It has been found to improve the GABA and dopamine levels in the brain, which helps in maximizing brain activity and decreasing stress. Theamine also helps in improving the quality of sleep and reducing the effects of caffeine.

Oat Straw

Also known as Avena Sativa, this is an extract found in wild oat straws. Research has found that it reduces neurological stress and exhaustion. It also improves overall cognitive function.

Cat’s Claw

Cat’s claw is a vine found in the rain forests of the Amazon. In many traditional medicines, cat’s claw is used for improving the immune system. It is also a great antioxidant and reduces the symptoms of arthritis. But the main reason why cat’s claw is used in Alpha Brain is its ability to improve cognitive performance.

Alpha GPC

Alpha GPC rapidly improves the availability of acetylcholine in the brain. Acetylcholine is one of the most important neurotransmitters. It is involved in almost all aspects of brain function, from processing information to memory. With higher levels of acetylcholine, cognitive functioning, such as focus and memory, can be improved.

Bacopa Monnieri

Bacopa is a common ingredient of many nootropics. It is an Indian herb that has been used for hundreds of years for increasing brain performance. It is a powerful memory booster and can even help those with mild cognitive impairment.

Huperzine A

The main function of Huperzine A is to inhibit the enzyme, acetylcholinesterase. This enzyme is responsible for the breakdown of acetylcholine. By stopping this enzyme, the concentration of acetylcholine in the brain starts to increase. This increases mental stamina, sharpens focus and improves memory. Huperzine A has even been found to improve cognition and memory in patients suffering from vascular dementia and Alzheimer’s, according to the Alzheimer’s Drug Discovery Foundation.


Phosphatidylserine is a compound that is immensely important for the proper functioning of the brain. It is one of the main structural components of brain cell membranes. It is also needed for proper cell signaling to the immune system that the life cycle of a neuron is complete. With age, the levels of phosphatidylserine gradually decline. The benefits of phosphatidylserine include better focus and improved memory.


This ingredient has been found to improve the flow of nutrients and oxygen to the brain. It also reduces inflammation.

Dosage & Side Effects

Since the exact quantities of all the ingredients is not known in Alpha Brain, recommending the right dosage can be tricky. But it is a good idea to take 2 capsules each day for optimal results. But avoid taking more than 3 capsules a day. The best practice would be to start with a smaller dose and gradually increase.

The capsules can be taken in the morning or early afternoon, with a light meal. By taking them 4 to 6 hours before sleep, you can achieve an improved dream state.

Since the Alpha Brain supplement is made of all-natural ingredients, this Onnit nootropic has minimal side effects. However, some users have reported temporary side effects, such as diarrhea, light-headedness, headaches, brain fog, dizziness, cramping, vomiting, weakness, rapid heartbeat, tremors and insomnia. In case you notice any of these side effects, it is best to discontinue use immediately.

The capsules are not intended for those under 18 years, nursing mothers and pregnant women.

How Does it Work?

Apart from personal experiences, studies also support the claims of Onnit Labs regarding Alpha Brain. In 2015, a study by Boston University found that verbal recall improved 12% with the help of Alpha Brain, as compared to a placebo. Improvements were also found in mental processing. Alpha Brain customer reviews also state other benefits, such as:

  • Improved concentration and attention levels.
  • Boosts memory.
  • Helps clear brain fog when under heavy stress.
  • Improves the ability of the brain to multitask.

The bottom line is that Alpha Brain supplement can be a great choice if you are looking for an all-natural nootropic. But, it is always a good idea to consult a doctor before using any supplement.
