A Deep Dive into Alpha Brain's Formula
Alpha Brain, developed by Onnit, is a nootropic supplement designed to support memory, focus, and overall cognitive function. Unlike many supplements that list individual ingredients and their precise dosages, the core of the Alpha Brain formula consists of three proprietary blends, making it more challenging to determine the exact amount of each component. Alongside these blends, the supplement includes specific individual ingredients known for their cognitive benefits.
The Onnit Flow Blend
This 650mg blend is designed to promote the production of alpha brain waves, which are associated with a state of relaxed alertness and creativity. The ingredients include:
- L-Tyrosine: An amino acid and precursor to the neurotransmitters dopamine, norepinephrine, and epinephrine. During stressful or demanding situations, supplementing with L-Tyrosine may help maintain cognitive function.
- L-Theanine: Found naturally in green tea, this amino acid promotes relaxation and can help reduce stress and anxiety, potentially improving attention and working memory.
- Oat Straw Extract: Derived from the stems and leaves of oats, this herbal extract is included for its potential anxiolytic properties, though clinical research supporting its effectiveness in this specific context is limited.
- Phosphatidylserine: A vital fat for cell membranes, especially in the brain, it is involved in nerve cell signaling and has been studied for its potential to improve cognitive performance, particularly in older adults. The source is often soy, which is a consideration for those with allergies.
The Onnit Focus Blend
At 240mg, this blend is formulated to aid the production of acetylcholine, a key neurotransmitter involved in memory, attention, and muscle control. The components are:
- L-Alpha glycerylphosphorylcholine (Alpha GPC): A compound that acts as a precursor to acetylcholine. It has been studied for its potential role in improving cognition, though more research is needed, especially in healthy individuals.
- Bacopa (leaf & stem) Extract: An herb used in Ayurvedic medicine, Bacopa monnieri has been traditionally used to enhance memory. Studies suggest it may help with visual processing speed and memory consolidation. However, the 100mg dosage in Alpha Brain is noted to be lower than amounts used in some studies.
- Toothed Clubmoss Extract: This is a source of Huperzine A, which blocks the enzyme that breaks down acetylcholine. By preserving acetylcholine, it may help improve cognitive function. The 400mcg dosage is consistent with clinical trial amounts. Caution is advised against taking more than the recommended dose due to potential acetylcholine overload.
The Onnit Fuel Blend
This is the smallest blend at 60mg and is intended to support nervous system communication. It contains:
- L-Leucine: An essential branched-chain amino acid important for protein synthesis. Its inclusion for nervous system communication is based on research, but the dosage in the blend is likely far lower than effective amounts used in studies.
- Pterostilbene: An antioxidant similar to resveratrol, it may offer neuroprotective benefits by protecting against oxidative stress. It is more commonly associated with benefits in individuals with neurodegenerative disorders.
Other Key Ingredients
In addition to the proprietary blends, Alpha Brain contains two notable individual components:
- Vitamin B6 (as Pyridoxine HCl): At 10mg per serving, this essential vitamin is crucial for the synthesis of neurotransmitters and overall brain function. While a deficiency can impair cognition, supplementing beyond the recommended daily intake might not offer significant extra benefits in healthy individuals.
- Cat's Claw (bark) Extract: A herbal extract with antioxidant and anti-inflammatory properties, traditionally used for various ailments. Animal studies have suggested cognitive benefits, but more human research is necessary.
Alpha Brain vs. Other Formulations: A Comparison

Conclusion: Understanding the Formulation
Alpha Brain is a complex nootropic supplement composed of three proprietary blends—Flow, Focus, and Fuel—along with individual ingredients like Vitamin B6 and Cat's Claw. These components are intended to work synergistically to support cognitive functions such as memory, focus, and verbal recall. However, the use of proprietary blends obscures the exact dosages of many key ingredients, making it difficult to verify their individual efficacy based on available clinical data. While some users report noticeable benefits like enhanced focus and more vivid dreams, others experience side effects such as headaches or gastrointestinal issues, and the effectiveness can vary widely among individuals. As with any dietary supplement, consulting with a healthcare provider is recommended before starting Alpha Brain to discuss safety and suitability.
