About Derek
Derek Giordano is the founder and editor of IQ Healthspan. He is a father of four with a lifelong interest in athletics and staying fit, and a long-standing interest in the supplement industry.
As he got older, his questions changed: less about how to perform and more about how to stay healthy for longer, and less about what the supplement industry was selling than about what the research actually shows. IQ Healthspan grew out of those questions. It is the resource he wanted for himself: plain-language explanations of longevity science, with the evidence on the page.
Derek is not a physician or a scientist, and the site does not ask you to take his word for anything. Articles link their claims to the published studies behind them, say plainly when the evidence comes only from animal or laboratory work, and are corrected in public when they get something wrong. Nothing here is medical advice: talk to your doctor before changing a medication, supplement or treatment.
How IQ Healthspan Works
Articles cite peer-reviewed research with numbered references that link to PubMed and the journal, so you can read each source yourself. Citations are checked against their PubMed records, and the strength of the evidence is described honestly: a randomized trial is not a mouse study, and the articles say which is which. Every article and guide was re-checked claim by claim against its sources in 2026, and every substantive change is listed on the corrections page. The full process is on our methodology page. Articles are researched, drafted and fact-checked with the help of AI tools, and every claim is checked against the studies it cites.
Editorial Principles
Primary Literature First
Articles start from peer-reviewed studies, not press releases or secondary coverage.
Evidence Weight Disclosed
Randomized trials, observational studies and animal or lab studies are clearly distinguished.
No Conflicts of Interest
No supplement partnerships, affiliate relationships or other financial conflicts.
Verifiable Citations
Numbered references with PubMed and DOI links, so you can check claims for yourself.
Topics Covered
IQ Healthspan covers biomarkers and testing, brain and cognition, cellular and mitochondrial health, epigenetics and aging, exercise and performance, hormones and peptides, longevity supplements, nutrition and fasting, research and clinics and sleep and circadian biology.
Editorial Independence
IQ Healthspan does not accept sponsorship or affiliate commissions from supplement makers, drug companies, longevity clinics or anyone whose products the site evaluates, and it does not currently carry advertising or sponsored content.
The Supplement Evidence Database rates each compound on published human research alone. Resveratrol, a heavily marketed longevity supplement, carries a harm signal there because of its effect on exercise training, while creatine, cheap and unglamorous, is rated as supported for strength.
