Function Buys SuppCo: What Independent Supplement Testing Really Reveals

Function.health is acquiring SuppCo — a platform that independently purchases supplements off-the-shelf and verifies their contents through an ISO 17025-accredited laboratory — and the rationale for the deal rests on a finding that most supplement users have not internalized: roughly half of top-selling supplements fail basic label accuracy standards.

The Trust Problem in the Supplement Stack

The supplement industry operates under a lighter regulatory framework than pharmaceuticals. The FDA does not require pre-market testing for efficacy, and label accuracy enforcement is reactive rather than systematic. For the biohacking practitioner building a precise supplement protocol around biomarker data, this creates a structural problem: the dose on the label may not be the dose in the capsule.

SuppCo’s TESTED program addresses this directly. The company anonymously purchases supplements from retail shelves, sends them to an ISO 17025-certified laboratory for independent analysis, and publishes the results through its consumer app — which has accumulated ratings across more than 35,000 products and analysis of over 500,000 supplement routines. The ISO 17025 standard is significant because it applies to the laboratory’s measurement and testing competence specifically, not just its management processes — it means the analysis itself meets a validated accuracy threshold.

The finding that roughly half of top-selling supplements failed basic label accuracy standards is not new to academic researchers, but it is striking in a consumer context. A magnesium glycinate product that contains 60% of the labeled dose delivers a different physiological effect than a product with accurate labeling — and the consumer has no way to distinguish them at point of purchase.

What the Acquisition Combines

Function operates a comprehensive biomarker testing platform offering more than 160 lab tests — including panels covering metabolic health, hormones, cardiovascular markers, and nutrient status — available to members across all 50 states. The platform pairs test results with clinical interpretation and has positioned itself as the infrastructure layer for proactive health monitoring.

SuppCo adds a verification layer that Function has lacked: independent evidence that the supplements a user is taking actually contain what the label claims. Combined, the platforms create a feedback loop — Function’s blood tests show what your magnesium or CoQ10 or omega-3 levels actually are, while SuppCo’s database shows whether the product you’re taking is accurately dosed enough to move those markers. The acquisition also surfaces a curation function: supplement recommendations from within Function can now be filtered by TESTED verification status, removing a category of recommendation uncertainty.
