What the study showed, in plain terms

AppleX is a 2026 industry-sponsored randomized placebo-controlled trial of a proprietary whole-apple polyphenol extract standardized to 15% fisetin. The product also contains other apple polyphenols, including quercetin, chlorogenic acid and procyanidins.

The trial is not yet recruiting in the latest public registry update and has no results. Even after results become available, the intervention is a multi-polyphenol extract, so an effect cannot be attributed to fisetin alone without additional evidence.

Key findings

  • Planned enrollment is 70 adults aged 45-70 years.
  • The intervention is 100 mg/day AppleX extract standardized to 15% fisetin for 24 weeks.
  • Primary endpoint is change in hsCRP; secondary/exploratory outcomes include fatigue, joint comfort and epigenetic aging metrics.

What this study can and cannot tell us

  • No results available.
  • Industry-sponsored proprietary extract rather than pure fisetin.
  • Other apple polyphenols prevent clean fisetin-specific attribution.
