The Bioage Reversal Breakthrough
1 day ago
- Dr. Fitzgerald’s 2018 clinical study was the first to show a diet and lifestyle intervention could reverse biological age — by over three years compared to controls — a finding even epigenetic clock pioneer Steve Horvath hadn’t thought possible.
- Follow-up research pinpointed polyphenol-dense “methylation adaptogens” as the primary drivers of that effect, and she’s now pursuing an NIH grant to explore whether polyphenols can influence not just exposomic aging (environmental wear and tear) but also programmed aging itself.
- Functional medicine providers already hold the toolkit that many newer “longevity” practitioners lack — community, mentorship, and in-person connection remain essential for translating that expertise into a thriving, resilient career.
