Onnit Alpha Brain claims to support memory, focus, and mental processing speed, thereby promoting overall cognitive function. It is marketed as a nootropic supplement, designed to enhance brain performance.

2. Ingredient Justification

The supplement contains a blend of well-known nootropic ingredients such as Bacopa Monnieri, Huperzia Serrata, and L-Tyrosine. Bacopa Monnieri has been used traditionally to enhance cognitive ability and recent scientific research supports its use for this purpose. For instance, a study by Stough et al. (2013) showed that Bacopa Monnieri improves memory performance in healthy adults. L-Tyrosine is an amino acid known to enhance cognition under stressful conditions, supported by a study by Deijen et al. (1999).

3. Recommended Dosage

The clinically recommended dosage for Bacopa Monnieri varies between 300mg to 450mg per day (Calabrese et al., 2008). Each serving of Onnit Alpha Brain contains 100mg, potentially requiring multiple servings to reach the clinically effective dose.

4. Clinical Trial Evidence

A randomized, double-blind, placebo controlled trial on Alpha Brain itself was conducted by Solomon et al. (2016). The study found that compared to a placebo, Alpha Brain significantly improved verbal memory and executive function. The dosages used in this study matched those found in the product.

5. Brand Transparency and Credibility

Onnit has been in business since 2010 and is transparent about its ingredients, providing a full list on their website. The founder, Aubrey Marcus, and current CEO, Jason Havey, are also publicly known. While they claim that their products are tested for safety and efficacy, specifics about these tests or their results are not readily available on their website.

6. Summary Verdict

Onnit Alpha Brain appears to be a reputable nootropic supplement with ingredients supported by scientific evidence. However, the dosage of some ingredients may be lower than the clinically effective dose. While the brand has a positive reputation, more transparency on product testing would further enhance their credibility. As with any supplement, it's recommended to consult with a healthcare professional before starting a regimen.
