Can supplements really improve cognitive function?
Some supplements have solid evidence for modest cognitive benefits. Creatine, omega-3s, and magnesium have multiple controlled trials behind them. No supplement will turn you into a genius overnight, but the best-studied options can meaningfully support focus, memory, and mental clarity.
Are these supplements safe to combine?
Most evidence-backed cognitive supplements are safe to combine at standard doses. However, always check for interactions with any medications you take. Our safety scores reflect each supplement individually — stacking multiple supplements warrants extra caution.
What does research quality X/6 mean?
Our 6-point research quality scale ranges from 1 (anecdotal/preclinical) to 6 (high-quality meta-analyses). A score of 4+ means there's at least one controlled human trial. We only rank supplements we've reviewed — absence from this list doesn't mean something doesn't work.
