Frequently Asked Questions
What is Metagenics and are its supplements safe to use in Canada?
Metagenics is a science-based supplement brand founded in 1983, with Canadian operations headquartered in Mississauga, Ontario. All Metagenics products sold in Canada carry Health Canada Natural Product Numbers (NPN), confirming they have been reviewed for safety, efficacy, and quality under Canada's Natural Health Products Regulations. Manufacturing facilities are audited by USP GMP, NSF International GMP, and Canada's Natural and Non-Prescription Health Products Directorate (NNHPD). Metagenics is also a certified B Corporation (since 2022) and offers lot-level quality transparency through its TruQuality® Guarantee, allowing customers to verify testing results for every formula by lot number.
How is Metagenics different from regular supplement brands sold in stores?
Metagenics differs from typical retail supplements in three ways. First, it is a practitioner-grade brand — formulated for therapeutic use and traditionally distributed through licensed healthcare providers, not mass retail, making it the #1 Doctor Recommended Professional Supplement Brand in North America. Second, its formulas are built on nutrigenomics research — the science of how nutrition interacts with genes — backed by hundreds of clinical studies, with a focus on bioavailability-optimized ingredient forms rather than generic powders. Third, it maintains multi-layer independent quality verification: USP GMP, NSF GMP, and NNHPD Canada audits, with every formula's testing results accessible online by lot number via the TruQuality® Guarantee.
How Metagenics products tested for quality and safety?
Every Metagenics product undergoes rigorous testing at every stage of production, including raw ingredients, finished formulas, and final encapsulation. We don’t just meet industry standards—we exceed them.
While the FDA requires minimal oversight for supplements, we invest over $1.5 million annually into quality assurance. That includes nearly 50,000 tests per year conducted by more than 70 global quality experts to ensure purity, safety, and potency.
Each product is triple-tested for identity, strength, and consistency—so what’s on the label is exactly what’s in the bottle. And to hold ourselves to an even higher standard, we also voluntarily submit every product for third-party testing to confirm quality and transparency you can trust.
