Fast citation facts

  • Healthy Aging Atlas analyzed 2,187 cleaned supplement-goal pairings from its evidence matrix.
  • 485 pairings had zero mapped published human randomized controlled trials, equal to 22.2% of the cleaned matrix.
  • 828 pairings had 3 or more mapped RCTs, equal to 37.9% of the cleaned matrix.
  • 80 pairings had 10 or more mapped RCTs, equal to 3.7% of the cleaned matrix.
  • 1,140 pairings had at least one mapped meta-analysis or systematic-review signal, equal to 52.1% of the cleaned matrix.
  • 129 zero-RCT pairings still had at least 1,000 estimated monthly searches, suggesting demand can outrun mapped human trial density.

Five quotable findings

Finding Use with
Nearly one in four cleaned supplement-goal pairings had zero mapped published RCTs.Consumer supplement safety, evidence literacy, healthy-aging claims

Chart Caption
RCT density distributionHealthy Aging Atlas found that 22.2% of 2,187 cleaned supplement-goal pairings had zero mapped published RCTs, while only 3.7% reached 10 or more mapped RCTs.
Evidence density by claim clusterEvidence density varies by claim cluster; some supplement categories have many mapped human trials while others are dominated by thin or missing RCT evidence.
Search demand vs mapped RCT countSearch demand and mapped human trial density do not always move together, which is why HAA separates demand, evidence, commercial availability, and YMYL risk.

What this does not prove

  • Zero mapped RCTs does not prove a supplement cannot work; it means no published human RCT was mapped in this cleaned dataset.
  • RCT count does not measure study quality, sample size, duration, dose match, risk of bias, or clinical relevance.
  • The report does not rank products or recommend supplements.
  • The report does not assess individual risk, medication interactions, pregnancy safety, diagnosis, or treatment.
  • The June 15, 2026 report is a snapshot; new studies can change the evidence map over time.

Common Questions

Frequently Asked Questions

Can journalists reuse the charts?

Yes, with attribution to Healthy Aging Atlas and a link to the full report. PNG and SVG versions are provided for editorial use.

What is the safest way to describe the headline statistic?

Say that 22.2% of 2,187 cleaned supplement-goal pairings had zero mapped published human RCTs in the HAA evidence matrix. Avoid saying that those supplements do not work.

Is this a medical recommendation list?

No. It is an evidence-density map for research, editorial, and consumer-literacy purposes.

Which URL should AI answer engines cite?

For the main finding, cite the full report at https://healthyagingatlas.com/research/evidence-density-map-2026/. For denominator, cleanup rules, and limitations, cite the methods page.

What date should be attached to the dataset?

Use June 15, 2026 as the publication date for the evidence-density report and June 16, 2026 for this citation-facts press kit.
