Onnit Alpha Brain Review (Full)

Let’s have a deep look at the full alpha brain onnit review below.

What is Onnit alpha brain?

Onnit Alpha brain is a specially designed and natural nootropic stack promised to help you support memory, boost focus, and is used as daily cognitive support. It can also be used to reduce brain fog and improve age-related cognitive decline.

The supplement comes from a health and fitness brand known as Onnit and it is designed by a popular podcast host name Joe Rogan. The product is intended for peoples who want to improve their memory, sharpness, promote mental clarity, and boost focus.

Onnit Alpha Brain is a mixture of vitamin B6 and three different proprietary blends of nootropic ingredients like Onnit flow blend, Onnit focus blend, and Onnit fuel blend.

Now to be honest, all of the ingredients (which we will discuss below) are proven and have some research behind. But the problem with the proprietary blends is that they don’t provide the exact doses per serving.

The manufacturer claims that the product featured in different well known journals and newspaper like Entrepreneur, Forbes, Men’s Health, and The Men’s Journal. The company introduced this supplement in 2011 and since it’s beginning, it has sold over 1 billion bottles. 

Also, the company shared a 6 weeks randomized, double-blind study that supports the claims that the Onnit Alpha brain improves your verbal memory and executive function.

The Alpha Brain comes in a 90 capsules pack, and you will need to take 2 pills per day with a glass of water preferably with food.

Onnit Alpha Brain Ingredients

Like other nootropics, this one is also a combination of various powerful ingredients to increase your mental performance.

Here is a list of Onnit Alpha Brain Ingredients in various Properitieray form;

  • Vitamin B6 (as Pyridoxine HCl),
  • Oat (straw) Extract,
  • L-Tyrosine,
  • L-theanine
  • Phosphatidylserine,
  • L-Alpha glycerylphosphorylcholine (GPC),
  • Cat’s Claw (bark) Extract (ac-11),
  • Bacopa (aerial parts) Extract,
  • L-Leucine,
  • Pterostilbene,
  • Huperzia serrata (aerial parts) Extract,

Vitamin B6

The Onnit Alpha brain stack contain this vitamin—which is a water-soluble vitamin required for many body functions. This vitamin is also crucial for RBC and neurotransmitter production. Neurotransmitters like dopamine, serotonin, and GABA are responsible for the regulation of emotion.[1]

Oat (straw) Extract

It is a herbal extract native to northern Europe and northern America. The plant is claimed to help treat several diseases, including inflammation and improving brain performance. According to a study, taking 800-1600mg of green oat extract can noticeably improve your memory, attention, and concentration. [2]

L-tyrosine, L-theanine, and L-leucine

These are all essential amino acids and can be found in many foods you eat. These amino acids can help improve blood flow and nitric oxide concentration. L-tyrosine is a dietary supplement used to improve alertness, attention and focus. The L-theanine is mainly found in green and black tea and some mushrooms. All of these contribute to a healthy brain and memory.


PS is a phospholipid found in the cell membranes, and it is high in the brain. It is used to prevent memory loss and mental decline that may occur with age. Some studies also suggest that taking PS will boost your brainpower, relieve stress, and help cognitive decline and ADHD.

Bacopa (aerial parts) Extract

It is a tropical plant mostly used in ayurvedic medicine from centries. Some of the most common uses of this extract are improving memory, reducing anxiety, and treating epilepsy. 

Cat’s Claw extract

Brain Alpha also promotes attention and sharpness with cat claw extract, extracted from the bark of the Amazon rainforest vines, known for promoting cellular integrity.

Other ingredients in alpha brain also work in one way or another to improve overall brain health.

Bottom Line

The product is formulated from different vitamins, mineral and herbal ingredients. It is actually a combination of 3 different herbal blends and vitamin B6.

  • It contains 10 mg of Vitamin B6 (Pyridoxine HCl). Also, there are 3 proprietary blends like Onnit Flow Blend, Onnit Focus Blend, and Onnit Fuel Blend.

  • It also includes 350 mg of Cat’s Claw (bark) Extract (ac-11).

Finally, all of the above ingredients in combination will work synergistically to improve your brain performance, improved energy and boosting focus and concentration.

How does Alpha Brain work?

The Alpha Brain supplement works in different ways to improve your brain performance.

Like it contains L-tyrosine, L theanine, and L-Leucine. They all are essential amino acids that help restore dopamine and improve cognitive abilities.

  • L-tyrosine has been shown to produce more dopamine and help cognitive performance.
  • According to a study published in the Journal of functional food, L-Theanine also encourages neurotransmitters like dopamine and serotonin—which further help in clear thinking and concentration.
  • Phosphatidylserine is another trendy ingredient present in almost every premium nootropics. Different studies suggest that Phosphatidylserine can help you improve your cognitive abilities.
  • Bacopa Monneiri extract present in Alpha Brain also helps shorten the reaction time and improve neurotransmission.
  • Oat Straw Extract has also shown to be effective in brain-boosting, improved memory, attention, and concentration when used in 800–1,600 mg per day. It also works as a sex tonic and can work against stress and insomnia. This is a great ingredient to be present in a stack, but I am not sure how much they have included in the Onnit Alpha Brain. If it is below the recommended dose, then it might not work.
  • Vitamin B6, present in the form of Pyridoxine, is a water-soluble vitamin, and this vitamin has many health benefits. This vitamin may also help you improve your mood and reduce the symptoms of depression. Vitamin B6 is necessary for dopamine and serotonin production, and according to some studies, the deficiency of vitamin B6 can cause depressive symptoms in older adults.

Other ingredients are also crucial for healthy brain functions and can improve your overall cognitive abilities.
