The supplement industry is facing a crisis of trust, and one company is stepping up to bridge the gap between what's promised and what's actually delivered. SuppCo has just unveiled a groundbreaking certification program designed to independently verify the active ingredients in dietary supplements. This initiative isn't just another rating system; it's a direct response to alarming findings that roughly half of popular supplements purchased off the shelf failed to meet basic label accuracy standards.
But here's where it gets controversial: This isn't a minor issue of 'close enough.' SuppCo's initial testing revealed some products contained 0% to 3% of their listed active ingredients, particularly in brands boasting the largest serving sizes. This suggests systemic failures in quality control, from sourcing raw materials to final product verification. "Whether the cause was manufacturing shortcuts, supplier variability, lack of internal testing or intentional deception somewhere in the supply chain, the end result was the same: products that made confident claims yet delivered almost none of what they promised," SuppCo stated in their 2025 testing retrospective.
And this is the part most people miss: Unlike many existing certifications that might rely on manufacturer-provided samples, TESTED by SuppCo purchases products anonymously, directly from retail shelves. This ensures the testing reflects what a typical consumer would actually buy, closing a significant loophole where a product could pass a certification test with a specially selected batch. This new program builds upon SuppCo's existing TrustScore system, which already evaluates formulation, manufacturing, and transparency before a product even hits the lab. Together, TrustScore helps users identify potentially trustworthy products, and TESTED by SuppCo confirms that trust with real-world verification.
The program debuts with a strong lineup of reputable brands including Momentous, Thorne, Metagenics, Gaia Herbs, Designs for Health, Fatty15, Solaray, Niagen, Integrative Therapeutics, and Pendulum, signaling a growing industry commitment to transparency. To earn the TESTED by SuppCo certification, products must meet or exceed 95% of their labeled active ingredient claims, verified by an independent ISO 17025–accredited laboratory. All test results, win or lose, are publicly available on SuppCo's product pages, empowering consumers with crucial information.
The supplement industry is indeed at an inflection point, as Jordan Glenn, head of science at SuppCo, explained. "Consumer expectations are rising, regulatory scrutiny is increasing, and independent verification is becoming a baseline expectation rather than a differentiator." Brands are realizing that transparency is the only truly durable competitive advantage in an increasingly noisy market. Jeff Byers, CEO of Momentous, echoed this sentiment, stating, "It’s easy for brands to talk about quality and boast big claims about their products, but it’s much harder to prove it. We chose to participate in TESTED by SuppCo because trust and accountability are how this industry moves forward. Transparency should not be optional."
SuppCo's approach is reminiscent of efforts by organizations like ConsumerLab and NSF International, but it tackles a fundamental structural issue. By purchasing products off the shelf, they are directly addressing the concern that some products might be 'certified' using batches that are not representative of what reaches consumers. This is a critical distinction that aims to close a meaningful loophole in supplement verification.
Now, here's a thought-provoking question for you: With such a significant portion of supplements failing basic accuracy tests, and with programs like TESTED by SuppCo aiming to bring more transparency, should the onus be solely on companies to prove their product's integrity, or should regulatory bodies like the FDA be more proactive in ensuring label accuracy before products even hit the market?
