Short answer: A genuinely trustworthy memory supplement names its specific mechanisms honestly, discloses negative research findings, and clearly states it isn't a substitute for medical assessment.
What to check when evaluating any memory supplement
Whether the brand discloses negative findings (like Ginkgo's GEM Study result) rather than only favorable research, and whether medication interactions are named specifically.
Why this category requires directing serious symptoms elsewhere
Memory problems that are getting worse, difficulty with familiar tasks, confusion about time or place — these warrant proper assessment, not self-treatment with a supplement.
⚠️ Worth knowing: a supplement is not the right first response, and delaying assessment is the real risk.
