Aster glehni extract powder,
does it really help with Improvement of age-related cognitive decline?
research showsAster glehni extract powder is a specific ingredient that passed an individual-recognition review including human evidence, but the sample, design, and cognitive efficacy results could not be verified in publicly available academic literature, and no independent replication was identified. It is therefore rated C. Published papers are mainly cellular or animal cognition studies, while a 12-week human trial for another indication did not test cognition.
ads claimProducts may present improvement of age-related memory, concentration, and cognitive function, but the publicly identifiable evidence extends only to nonpublic human evidence submitted for the specific recognized ingredient.
Useful facts when choosing a product
- The stated daily intake for the recognized ingredient is reported as 960 mg/day.
- The cognitive claim applies to a specification-defined extract powder, not ordinary Aster glehni food.
- Without a published cognitive clinical paper, the sample size and primary-endpoint details cannot be independently verified.
- A 12-week human trial for another indication reported no adverse events or changes in safety parameters.
What the research actually shows
The Kang 2026 regulatory review lists Aster glehni extract powder as a Korean individually recognized ingredient for cognitive-function improvement and explains that human intervention evidence is part of an individual-recognition dossier. Liao 2019 reported improved memory behavior and signaling in mice with scopolamine-induced impairment, but it was not a human study. The 12-week Lee 2020 RCT assessed uric acid in mild hyperuricemia, found no between-group benefit at the final time point, and did not measure cognition.
Why this is classified as C (42)
The existence of a human trial is accepted from the individual-recognition process, while regulatory recognition itself is not used as efficacy evidence. With no public results or independent replication and evidence concentrated in an applicant-specific ingredient, the rating is low C at 45 points.
Counterpoint. A cognitive signal may remain possible for the specific standardized ingredient, but extrapolation to ordinary Aster glehni or other extracts is a separate issue.
Rejudgment record. New judgment — Human evidence for individual recognition exists, but public cognitive clinical results and independent replication are lacking and evidence is concentrated in an applicant-specific ingredient

| Study | Design | Sample | Funding | Endpoint | Result | Weight |
|---|---|---|---|---|---|---|
| Kang P et al. 2026 | Review of the regulatory system and individually recognized ingredients | Korean government research support | Classification of individually recognized ingredients and dossier evidence requirements | Listed Aster glehni extract powder as an individually recognized cognitive ingredient and described the requirement for human intervention evidence. | Confirms existence of human evidence; effect size unknown | |
| Liao Y et al. 2019 | Preclinical study in mice with scopolamine-induced cognitive impairment | Included authors from the Koreaeundan R&D center | Water maze, passive avoidance, Y-maze, AChE, and signaling proteins | Reported improvement in memory behavior and selected signaling pathways. | Preclinical, manufacturer-linked | |
| Lee S et al. 2020 | Randomized double-blind placebo-controlled trial for another indication | Multiple authors were affiliated with Koreaeundan | Uric acid, xanthine oxidase, inflammatory markers, and safety | No between-group uric-acid benefit was found at 12 weeks, and no adverse events or safety-parameter changes were reported. Cognition was not measured. | Supportive for safety, outside the efficacy claim |
