Onnit Alpha Brain - Does It Work?-Review

What is Onnit Alpha Brain?

Onnit Alpha Brain is a supplement which is designed to enhance the performance of the brain. The brain is one of the most important organs in the entire body and it plays a major role in our daily living. If our brains become fatigued, our health and wellness can easily suffer. In this review we examine the ingredients in Onnit Alpha Brain and determine their effectiveness to decide whether this product presents a good value for money.

Ingredients & How It Works

  • Vitamin B6
  • L-Tyrosine
  • L-Theanine
  • Oat (straw) Extract
  • Phosphatidylserine
  • Cat’s Claw (bark) Extract (ac-11)
  • L-Alpha Glycerylphosphorylcholine
  • Bacopa Extract
  • Huperzia Serrata Extract
  • L-Leucine
  • Vinpocetine
  • Pterostilbene

Vitamin B6 is important in brain cell metabolism, specifically for the substance homocysteine.  Research has shown that lower levels of homocysteine are associated with decreased brain degeneration. L-tyrosine and L-theanine are important precursors for neurotransmitters and phosphatidylserine is an important component of brain cell membranes which regulate the functions of these neurotransmitters. Oat straw extract does contain many vitamins and alkaloids but there has been little scientific study on its effects in the brain. Cat’s claw extract is quite similar in that scientifically it has been determined that it contains many important substances but there is little scientific evidence to conclude that it has any health benefits. Alpha glycerylphosphorylcholine, is an ingredient for neurotransmitter synthesis. Bacopa extract and Huperzine extract have both been shown to enhance the effects of neurotransmitters and protect the brain. Vinpocetine and Pterostilbene are both said to protect the brain as well but there is only some evidence in rabbits for this in scientific literature.

Daily Serving

Two capsules must be taken daily with a light meal preferably in the morning or early afternoon.  Two capsules may be taken in evening to enhance dream state. However, it is quite important that customers do not take more than three capsules in 24 hours.

The manufacturer groups the ingredients as proprietary blends so the amount of each ingredient is not specifically given.

The Cost

A bottle of 30 capsules can be bought online for $29.71. Onnit offers deals for buying in bulk. The first is the purchase of two bottles for $50.50.  Otherwise, a bottle of 90 capsules can be purchased for $67.96.


Onnit offers a guarantee which is valid for three months. Essentially customers must inform the manufacturer of their dissatisfaction and their money will be returned. The customer need not return the package at all.

Our Review Summary Of Onnit Alpha Brain

Onnit offers their supplement with a decent guarantee. Their directions for use are quite clear too.  However,  we have major doubts in the possible effectiveness of this product because their ingredients lack sufficient research. The customer reviews for this product also express quite significantly that many customers are not that impressed with this product.

We also think that the price of this supplement is quite high compared to many similar supplements which actually have better research about their ingredients. We therefore don't find this product to be one of the best brain boosting supplements out there.
