No room for interpretation —
QED seeks proof
QED (quod erat demonstrandum) means "which was to be demonstrated" in Latin. This abbreviation is traditionally written at the end of a mathematical proof. By choosing this abbreviation as our brand name, we commit to creating only evidence-based products.
What makes QED different
Open formulas
We believe in full transparency — our supplements contain no proprietary blends, and we publicly disclose every ingredient along with its exact dosage, so you always know what you’re taking and why
