Frequently asked questions
How does FocusCheckup choose which products to review?
We review products in three categories: sleep, focus, and cognitive wellness. Selection is based on user demand, scientific plausibility of the mechanism, and the quality of available evidence. We do not accept payment from manufacturers to review or rank products. Editorial assessment is independent of any affiliate relationship.
Are the reviews on FocusCheckup independent?
Yes. We are an affiliate publisher — meaning we may earn a commission when readers purchase through our links — but editorial judgment is separate from commercial relationships. Scores, recommendations, and limitations are based on the same evaluation framework regardless of affiliate payout.
How often are reviews updated?
Each review carries an Updated date. We revisit reviews when a product reformulates, when new evidence becomes available, or when user reports shift significantly. Substantial updates trigger a republish; minor edits update the dateModified field without changing the review's score unless warranted.
What's the difference between a Review and a Comparison?
A Review is a complete editorial assessment of a single product — mechanism, evidence, pros and cons, who it's for. A Comparison places two products side by side, identifying overlap and the specific cases where one fits a profile better than the other. Comparisons are most useful when readers are already considering both options.
Does FocusCheckup provide medical advice?
No. All content is for informational and educational purposes only and does not constitute medical advice, diagnosis, or treatment recommendations. Products covered are not evaluated by the FDA for the treatment of any condition. Readers with health conditions or who take medications should consult a qualified healthcare professional before using any wellness product.
