Life Extension's Commitment to Quality
Life Extension is known for its high-quality nutritional supplements developed with scientific research. The company prioritizes transparency and stringent manufacturing practices to ensure product purity, potency, and effectiveness.
Rigorous Manufacturing and Ingredient Sourcing
Life Extension follows Good Manufacturing Practices (GMP). Their facilities are GMP registered by NSF International, an independent body that audits them bi-annually. This registration confirms compliance with federal standards. Ingredients are selected based on purity, potency, and scientific validation, not just cost. While sourcing ingredients globally, 99% of their supplements are manufactured in the USA. Ingredients are also checked for contaminants such as heavy metals and pesticides, and most products are non-GMO.
Third-Party Testing and Transparency
Life Extension uses independent, third-party labs to test finished products for potency and purity, surpassing minimum FDA requirements. The brand's quality has been acknowledged by organizations like ConsumerLab.com. Their fish oil products are part of the International Fish Oil Standards Program (IFOS), which tests each batch for contaminants, stability, and potency. A Certificate of Analysis (COA), detailing test results, can be requested by customers for any product.
Science-Based Formulation
Formulations are based on current scientific research. They often use highly bioavailable, patented ingredient forms like Bio-Quercetin phytosome or Crominex® 3+. Life Extension supports research and provides scientific details for its products online, aiming for optimal nutritional support.
A Critical Look at Life Extension
Despite a strong focus on quality, some aspects of Life Extension products warrant consideration.
Tablet Disintegration Concerns
Innerbody.com conducted an independent review which found that some Life Extension tablets did not fully disintegrate in simulated stomach conditions, which could potentially affect absorption. They recommended opting for capsules or softgels instead of tablets. Life Extension's FAQs mention excipients for dissolution, but the external tests raise questions about actual performance.
Past Regulatory Scrutiny
Life Extension has faced regulatory issues with the FDA in the past due to ambitious health claims. While showing a commitment to wellness research, this highlights the need for consumers to evaluate supplement claims critically and focus on the scientific evidence for individual ingredients.
