NCT07678346

Brief Summary

The goal of this clinical trial is to learn if AppleX™ Apple Extract can help lower systemic inflammation in adults aged 45-70 with signs of low-grade inflammation. It will also look at the extract's effects on fatigue, joint comfort, and biological aging metrics. The main questions it aims to answer are:

  • Does taking AppleX™ Apple Extract daily lower high-sensitivity C-reactive protein (hsCRP) levels, a key marker of inflammation in the blood?
  • Does AppleX™ Apple Extract improve participant-reported fatigue and joint comfort?
  • Does the extract slow down biological or epigenetic aging metrics compared to a placebo? Researchers will compare AppleX™ Apple Extract to a placebo (a look-alike capsule that contains no active ingredients) to see if the apple extract has a measurable anti-inflammatory and healthy aging effect.
