How I Test

Products covered here are selected based on what's circulating in the brain health supplement space: things appearing in forums, in reader questions, or in the ingredient research already being tracked. Paid placements, sponsored reviews, and products sent in exchange for positive coverage don't get published. If something arrives as a PR sample, the review says so and runs on the same evaluation rubric as anything purchased at retail.

Nothing gets reviewed on fewer than three weeks of daily use, and most evaluations run four to five weeks. The first week of any new supplement is nearly useless for assessment. Novelty effects, expectation, and ordinary day-to-day variation in focus and energy make early impressions unreliable. The question I'm answering is whether a consistent signal shows up across a full testing window, not whether something felt different on day three.

Each cycle covers one product at a time, purchased at retail without advance notice to the manufacturer. Running two untested supplements simultaneously makes attribution impossible, the same way a financial audit can't assign variance to a single line item when multiple accounts changed at once. Every morning before coffee: a short log entry. Word recall, processing speed in the first hour, effort required for routine tasks, any side effects worth noting. Same four questions, same time of day, every day of the testing window. That consistency is what makes the data comparable across products and months. Cost-per-day is logged throughout alongside the subjective entries. If something costs more than a decent lunch per day and produces no consistent signal distinguishable from background noise, it goes in the rejected tab. The rejected tab currently holds eighteen entries. That number is a sign the method is working, not a complaint.

Before I buy anything, I check what's actually available about sourcing: third-party certificates of analysis when a brand publishes them, full ingredient disclosure over proprietary blends whenever there's a choice. Proprietary blends without disclosed doses don't carry the same confidence weight as products with fully labeled formulas. When an ingredient claim in a product description conflicts with what published research actually says about that compound, the review notes the discrepancy directly.

Affiliate Relationships

Some links here are affiliate links. Click one, buy the thing, and I get a small commission at no extra cost to you. The commission doesn't get a vote in which products end up reviewed or how the review comes out. Eighteen rejected entries and counting say a product being junk gets written up as junk, commission or not.

Limitations

Everything here reflects one person's direct experience and personal observation, tracked with the methods described above. The information on this site is based on personal experience and research for informational purposes only and is not a substitute for professional medical advice. Anyone weighing supplements for cognitive health, particularly those with neurological conditions, existing medication protocols, or a medical history that intersects with cognitive function, should consult a qualified clinician before making changes. The tracking methodology and cost math are genuinely useful for evaluating claims made about a product. Medical guidance is not what's on offer here, and the site doesn't position itself as a substitute for professional care.

Get in Touch

If a product reviewed here gets reformulated or recalled, or if a factual error turns up in a published piece, the post gets updated and the correction is noted with a date. For substantive changes, the original text stays visible with a strikethrough so the revision is transparent. For questions, corrections, or feedback, see the contact page.
