Home / Our Science
Every ETERNIA formulation is built on a foundation of peer-reviewed clinical evidence, pharmaceutical-grade manufacturing, and unyielding ingredient transparency. Here is exactly how we do it.
Our scientific team systematically reviews thousands of peer-reviewed studies across nutrition science, sports medicine, and pharmacology journals to identify formulation targets with the strongest evidence base.
We select only pharmaceutical-grade active ingredients at clinically validated dosages. Every raw material supplier is audited, and Certificate of Analysis documentation is required before any ingredient enters production.
All ETERNIA products are manufactured in FDA-registered, GMP-certified facilities. Production follows strict SOPs with in-process quality checks at every stage from blending through encapsulation and final packaging.
Each production batch undergoes comprehensive third-party testing by ISO-accredited laboratories. Tests include identity verification, potency assay, microbiological safety, heavy metal screening, and contaminant absence confirmation.
ETERNIA implements a multi-stage quality control framework that begins with raw material auditing and continues through in-process monitoring, finished product testing, and post-release stability studies. No product is released without passing every quality gate in our system.
Confirms the correct ingredient at the declared concentration using validated analytical methods.
Tests for arsenic, cadmium, lead, and mercury against regulatory limits.
Screens for bacterial contamination, mold, yeast, and specified pathogens per USP standards.
Ongoing shelf-life studies confirm potency and safety through the product's full use period.

Pharmaceutical-grade supplement manufacturing means producing nutritional supplements to the quality, purity, and manufacturing control standards required for pharmaceutical drugs. This includes GMP-certified facilities, batch traceability, in-process quality monitoring, and independent finished product testing. It is a higher standard than food-grade supplement manufacturing, which has less stringent documentation and testing requirements.
Third-party testing means having an independent laboratory, not the manufacturer, verify what is in a finished batch of supplements. It tests for ingredient identity, stated potency accuracy, microbial contamination, and heavy metal presence. It matters because a manufacturer testing their own product has an obvious commercial interest in the outcome. An independent laboratory does not.
Every ETERNIA formula has been developed with reference to the doses used in peer-reviewed clinical trials. We do not set doses based on what fits neatly into a standard capsule size or what minimises raw material cost. If the clinical literature demonstrates benefit at 300mg of Magnesium Citrate, that is the dose we use. Our Science page documents the rationale behind our key formulation decisions.
Dietary supplements are not FDA approved in the United States. The FDA regulates dietary supplements differently from pharmaceutical drugs. However, our manufacturing facilities are FDA-registered, meaning they are subject to FDA inspection and must comply with current Good Manufacturing Practice (cGMP) regulations for dietary supplements, which are the highest manufacturing standards applied to this product category.
