Alpha Brain falls short.
Onnit's nootropic stack, backed by two clinical studies and NSF Certified for Sport. Sold direct to Australian buyers by the brand. Well suited for Australian athletes and mainstream shoppers.
What it does
Alpha Brain is Onnit's flagship nootropic, first released in 2011 and popularised through Joe Rogan's podcast. It is sold direct to Australian buyers by the brand. National Sanitation Foundation (NSF) Certified for Sport makes it suitable for Australian drug-tested athletes.
How it works
Alpha Brain uses three proprietary blends -- Onnit Flow Blend, Focus Blend, and Fuel Blend -- containing cholinergics (Alpha-GPC), adaptogens (Bacopa), and amino acids (Tyrosine, Theanine). The label states each blend's total and two individual amounts (Bacopa 100mg, Huperzine A 400mcg): Bacopa, Alpha-GPC (at most 140mg) and L-Tyrosine (at most 650mg) fall short of their clinical doses, and the other blend members cannot be checked individually. The two published studies (Onnit-funded, 2016 and 2021) tested the full formula and showed statistically significant improvements in verbal memory and executive function versus placebo.
What to expect
Day one: subtle focus improvement, particularly for users new to cholinergic supplements. It contains no caffeine. Onnit's 30-day money-back guarantee covers the first purchase of each product made directly on Onnit.com. Ships from the US to Australia -- check the delivery estimate for Australia at checkout.

Ingredient quality
Number and quality of evidence-graded ingredients. Trademarked extracts and standardized actives raise this score.
Dosing vs. clinical evidence
The share of ingredients with a reference dose on our ingredient pages whose label-stated daily amount meets that page's minimum. Amounts the label hides (blend shares) or states on a different basis count as not met; ingredients with no reference page are listed but not scored.
Formula transparency
Full disclosure of every ingredient at its exact dose. Proprietary blends are scored as opaque.
Value for money
Cost per month relative to per-serving clinical doses delivered. Cheaper products with underdoses score lower.
Brand trust
Brand reputation, third-party testing, refund track record, and Trustpilot signal across multiple years.
