Certificates of Analysis

Why Certificates of Analysis Matter

At Longevix, we believe you have the right to know exactly what's in your supplements. That's why we subject every batch of every product to rigorous third-party testing and publish the results for everyone to see.

Our Certificates of Analysis (COAs) verify the purity, potency, and safety of each product, ensuring they meet our strict quality standards and contain exactly what we claim on the label—nothing more, nothing less.

Frequently Asked Questions

What is a Certificate of Analysis (COA)?

A Certificate of Analysis (COA) is a document issued by an independent laboratory that confirms a product's specifications. It verifies that the product contains the ingredients in the amounts claimed on the label and is free from harmful contaminants.

Why should I care about COAs?

Studies have shown that many supplements don't contain what's claimed on their labels. COAs provide proof that you're getting exactly what you pay for—nothing more, nothing less. They're your assurance of product safety, potency, and quality.

How often do you test our products?

We test every single batch of every product. No exceptions. When a new batch is produced, samples are immediately sent to our third-party laboratories for comprehensive analysis before being made available for purchase.

What do you test for?

Our comprehensive testing includes: Potency (to verify ingredient amounts), Purity (to confirm identity and composition), Heavy metals (lead, mercury, cadmium, arsenic), Microbiological contaminants (bacteria, yeast, mold), and Solvent residues (when applicable).
