Claire Donovan

Claire leads supplement research at Health Verdict. She built and maintains the framework behind every ranking on the site.

What she does

Claire's work centers on three things: reading the clinical-dosing literature for each category, analyzing what's actually on product labels, and cross-checking brand claims against third-party Certificates of Analysis. She spends most of her time on the unglamorous part of supplement reviews — matching milligrams on a label to the doses that produced results in published trials.

Her focus areas span the metabolic, cognitive, longevity, and daily-nutrition categories, where the gap between marketing and clinical evidence tends to be widest.

The methodology she maintains

Every Health Verdict ranking follows the same framework: read the research and identify the dose and form that produced measurable results, then test each product label against that bar. Proprietary blends and undisclosed doses are flagged rather than guessed at, and aggregated user outcomes inform the limitations section of each ranking.

Editorial independence

Health Verdict earns affiliate commissions when readers buy through our links, but Claire's rankings are built before any commercial relationship is considered — and commission never changes the order. If a top-ranked product has no affiliate program, it still ranks first.
