📅 Last updated: April 2025The information, tools, articles, and content on IQ Healthspan are intended for educational and informational purposes only. Nothing on this site constitutes medical advice, and nothing should be construed as a substitute for the advice of a qualified physician, registered dietitian, pharmacist, or other licensed healthcare professional.
Do not use information from this website to self-diagnose, self-treat, or make decisions about your medical care without consulting a qualified healthcare provider.
IQ Healthspan was built to translate peer-reviewed longevity research into accessible, accurate content for motivated adults. Every article, tool, biomarker guide, supplement database entry, and protocol comparison on this site is designed to educate — not to diagnose, treat, cure, or prevent any disease or medical condition.
Understanding longevity science is valuable. But that understanding should inform conversations with your healthcare provider, not replace them. The difference between reading about ApoB and having your ApoB managed by a physician who knows your full health history is significant — and matters in ways that no website can replicate.
Using this website, its tools, or its content does not create a physician-patient relationship between you and IQ Healthspan, its founder, or any person associated with this site.
All content on this site is researched against peer-reviewed scientific literature, with factual claims sourced to published studies via numbered citations. This editorial process ensures accuracy against published research — it does not constitute clinical consultation with individual readers and should not be relied upon as personal medical advice.
Longevity research describes population-level associations and averages. Your individual response to any intervention — dietary change, exercise protocol, supplement, or medication — may differ substantially from what population studies show. Factors that affect individual response include:
This is why we consistently recommend discussing any significant change to your diet, exercise, supplement regimen, or health practices with a qualified physician who knows your specific situation — not because we doubt the evidence, but because the evidence describes averages and your situation is individual.
Our Supplement Evidence Database provides evidence grades, mechanism descriptions, dosing ranges, and safety considerations based on published human clinical research. This information is educational. It does not constitute a recommendation to take any specific supplement, and it is not a substitute for:
Prescription compounds (Grade Rx in our database) — including rapamycin, metformin, GLP-1 agonists, and acarbose — require physician prescription and supervision. They carry real risks, real drug interactions, and real contraindications. Using them without medical supervision is dangerous. The fact that we discuss their longevity evidence does not constitute a recommendation to obtain them outside the medical system.
On drug interactions: Many supplements interact with prescription medications in clinically significant ways. Berberine can substantially raise statin blood levels. High-dose omega-3s have antiplatelet effects that matter if you take blood thinners. St. John's Wort dramatically reduces levels of many medications. Before adding any supplement to your regimen, discuss it with your prescribing physician or pharmacist, particularly if you take any prescription medication.
Tools on this site — including the Biological Age Calculator, the Lab Results Interpreter, the Personal Longevity Dashboard, and the Longevity Stack Builder — are educational estimation and tracking tools, not diagnostic instruments.
Produces a proxy estimate based on self-reported lifestyle factors. It is not a clinical biological age measurement. True biological age requires laboratory testing (epigenetic clocks, validated biomarker panels). Uncertainty is ±3–5 years. Do not use this result to make medical decisions.
Provides educational context comparing your values to longevity-optimal ranges from published research. It does not diagnose any condition. Any result flagged as "Needs Attention" should be discussed with your physician — the tool's output is not a clinical assessment.
A personal tracking tool for longitudinal trends. Trend data is informative but not diagnostic. Share your dashboard export with your physician to inform your conversations — do not use it as a substitute for physician-ordered testing and clinical interpretation.
Summarises population-level evidence for various health interventions. The "winning" protocol in a comparison may not be optimal for your individual situation, health status, or goals. Individual responses vary substantially from population averages.
IQ Healthspan's content is written and edited by Derek Giordano, with all factual claims sourced to peer-reviewed studies via numbered citations.

Reviewer involvement means that claims in our content are consistent with peer-reviewed science as understood at the time of publication. It does not mean that any reviewer is endorsing any intervention for any specific individual.
We strongly encourage you to seek the guidance of a qualified physician or other licensed healthcare professional with any questions you may have regarding a medical condition, before undertaking any diet, exercise, supplement, or other health regimen, and before discontinuing any medication or treatment your physician has recommended.

We make every effort to ensure the information on this site is accurate, complete, and current. Longevity science is a rapidly evolving field. Research findings can change, be refined by new studies, or be superseded by subsequent evidence. While we update our content when significant new evidence emerges, we cannot guarantee that every page reflects the most current state of research at any given moment.
Our Research Radar publishes monthly updates covering the most important new findings. Evidence grades in the Supplement Evidence Database carry a last-reviewed date. Articles display their publication and review dates.
