Health testing company Function has announced its acquisition of SuppCo, an independent supplement rating platform, in an effort to connect biomarker testing with personalised supplement guidance.
More than half of Americans take dietary supplements, yet the category has long lacked an independent standard for trust, efficacy and safety.
The acquisition reflects increasing pressure on the nutraceutical sector to improve transparency, verification and evidence standards as consumers become more sceptical of marketing-led claims.
Function already offers extensive biomarker testing and recently expanded its lineup to include MRI and CT scans.
SuppCo's supplement ratings platform covers more than 35,000 products and 500,000 routines, using a TrustScore rating system and a dedicated research arm to grade products, which it says adds an "independent layer to guide supplement choices."
Earlier this year, the brand launched TESTED by SuppCo, an independent certification programme that anonymously purchases off-the-shelf supplements and verifies their active ingredients through an ISO 17025-accredited laboratory.
Prior testing initiatives revealed that roughly half of the top-selling supplements failed to meet basic label accuracy standards — a major issue for manufacturers, regulators and ingredient suppliers.
Function's integration of supplement analysis points to a broader trend toward personalised nutrition and precision supplementation based on biological data rather than demographic assumptions.
The deal also demonstrates convergence between digital health platforms, clinical diagnostics and supplement guidance — potentially reshaping how nutraceutical products are recommended and monitored.
"Supplements are powerful when used correctly. The problem is that many people are taking the wrong ones or the wrong dose from sources they have no reason to trust," said Steve Martocci, co-founder and CEO of SuppCo.
"For decades, the public has lacked the tools to know the difference."
We built SuppCo as an independent trust layer to help people build the right supplement stack for their goals. Joining Function pairs that independence with the one thing that's always been missing: a more comprehensive view of your biological data to understand how supplements are actually working for you.
"You are what you put in your body," added Jonathan Swerdlin, CEO and co-founder of Function.
"Food, prescriptions and supplements are inputs that shape your biology."
SuppCo cuts through the noise of supplement marketing by organising your supplement routine using grounded scientific rigour. Function pairs that with your lifelong baseline in one personalised platform.
Function added that the acquisition marked the next step in its build toward the AI health operating system.
