Questions & Answers

When supplementing with Life Extension products, please rest assured that you are taking the highest-quality products. In fact, Life Extension's quality control and quality assurance measures are regarded as the most stringent and advanced in the industry. Please note that we use raw materials that have scientific validation for dosage, safety, and effectiveness. All our raw materials go through stringent testing to meet our high-quality standards. Testing is performed for microbes, heavy metals, disintegration, potency, and quantity of active ingredients in the finished product. Testing methods are High-Performance Liquid Chromatography, Gas Chromatography, or ICP-Mass Spectrometry but other methods may be used. Only when raw materials meet Life Extension's specifications are they released for production. This information is available on our Certificate of Analysis (COA), which can be provided upon request.

Based on research studies, some effects were seen as early as 30 days with lasting effects seen after 90 days. We suggest following the study duration to determine efficacy. Nonetheless, the amount of time to see benefits can also be influenced by one's unique biochemistry, use of medications, and the extent of support needed. Biochemical individuality is the concept that each person's nutritional and chemical makeup is unique and that dietary and other needs, therefore, vary from person to person.
