About Life Extension® Protocols
Science-based educational health information from Life Extension
What Are Life Extension® Protocols?
Life Extension Protocols are in-depth, freely accessible educational resources that review a wide range of health concerns and wellness topics. Each Protocol is designed to help readers understand what the current scientific and medical literature says about conventional care, lifestyle measures, laboratory markers, and integrative approaches.
Our goal is to provide clear, science-based information intended to support general health literacy and informed discussions with qualified healthcare professionals. We aim to explain the evidence accurately and with appropriate context, especially in areas where the science is evolving, mixed, or limited.
Editorial Approach
Protocols are developed according to editorial standards that prioritize scientific accuracy, context, balance, and source fidelity. The purpose of Life Extension® Protocols is educational: to help readers understand the evidence, including what is known, what remains uncertain, and what limitations or safety considerations may be important. Editorial decisions about what evidence to include, how findings are characterized, and what conclusions are supported are based on scientific merit, relevance to the topic, and the strength and applicability of the evidence.
How We Evaluate Evidence
Life Extension® Protocols rely primarily on peer-reviewed research published in reputable scientific and medical journals, along with clinical guidelines, consensus statements, and other authoritative sources from relevant professional or scientific organizations.
