Function Buys SuppCo: Transparency Is Now a Brand Asset

On May 12, 2026, Function — the digital health platform built around continuous biomarker monitoring — acquired SuppCo, a supplement intelligence company known for its TrustScore system and ISO 17025-accredited label verification program. The deal didn't make mainstream financial headlines, but inside the supplement industry, it should.

This isn't a story about two companies merging. It's a story about what the market is demanding from supplement brands right now, and what happens to the brands that don't respond.

What the Deal Actually Combines

Function's platform tracks real physiological data. Members get regular blood panels covering dozens of biomarkers, and the platform translates those results into actionable health guidance. SuppCo's infrastructure does something different but complementary: it audits what's actually inside supplement products and assigns verified quality scores based on ISO 17025-accredited third-party lab testing.

Put those two capabilities together and you get something that hasn't existed at scale before. A consumer can now track whether a supplement is moving their biomarkers in the right direction, while simultaneously verifying that the product label reflects what's actually in the capsule. That's a closed loop of accountability that no single player in the supplement space has been able to offer.

For brands, the implication is direct. If your product is inside Function's ecosystem and it doesn't perform or doesn't pass verification, that data is visible. If it does perform and it does pass, that data becomes a conversion tool.

A $164 Billion Market With a Trust Problem

The global vitamins and supplements market was valued at $164.4 billion in 2025. It's projected to reach $284.26 billion by 2034, growing at a 6.29% CAGR. That's a generational commercial opportunity, and it's being built on a foundation that still has serious credibility issues.

Independent audits have repeatedly found that a significant portion of supplement products contain inaccurate label claims. Some products are underdosed. Others contain contaminants not listed on the label. A few high-profile FDA warning letters each year keep consumer skepticism alive, even among buyers who purchase regularly.

The trust gap isn't just a reputational inconvenience for brands. It's a structural drag on category growth. When consumers don't trust labels, they churn. They switch brands on price rather than loyalty. They don't upgrade to premium SKUs. The ceiling on customer lifetime value stays low.

Function's acquisition of SuppCo directly addresses this. By pairing biomarker outcomes with verified label data, the platform creates a credibility infrastructure that premium brands can plug into. That's not charity. It's a toll road, and the brands that want access to high-trust, high-retention consumers will pay to be on it.

Plant-Based Supplements Are Raising the Bar Further

Within that broader market, plant-based supplements are growing faster than the overall category. Consumer demand for natural sourcing, cleaner ingredient decks, and verifiable origin is driving this segment ahead of synthetic alternatives. It's a trend that rewards transparency at every layer of the supply chain.

That's a challenge for brands operating on legacy formulations with opaque sourcing. And it's an opening for brands that can prove purity at scale. Verification platforms like SuppCo's TrustScore become more valuable, not less, as the plant-based segment expands, because the complexity of validating botanical ingredients is significantly higher than validating synthetic compounds.

This connects to a broader shift in how wellness-focused consumers make purchasing decisions. Brands like Cymbiotika have already demonstrated that transparent formulation, clean sourcing, and community-driven credibility can generate serious investor confidence. Cymbiotika's $25M seed round backed by celebrity investors showed that the market rewards brands with a verifiable story, not just a compelling product photo.

Vertical Integration Is Accelerating in Parallel

The Function-SuppCo deal didn't happen in isolation. Five days earlier, on May 7, TopGum announced a $35 million acquisition of PL Developments' U.S. gummy manufacturing operations. That deal is structurally different but signals the same underlying pressure: brands are moving to control quality from production through to point-of-sale.

TopGum's move is about manufacturing control. Function's move is about verification and outcomes. Together, they illustrate the two strategic directions available to serious supplement brands right now. You either own the production process so you can guarantee what goes in, or you invest in verified proof systems that demonstrate quality to consumers after the fact. The most credible brands will eventually need both.

This vertical integration dynamic mirrors what's happening in other fitness industry segments. EōS Fitness acquired 14 gyms in Q1 2026 and reinvested $10 million in existing locations, applying a similar logic: own more of the value chain, then upgrade it from within. The supplement category is following the same playbook, just with capsules instead of squat racks.

Third-Party Testing Is No Longer a Checkbox

Here's where the Function-SuppCo acquisition has its most direct commercial implication for supplement brands. Third-party testing has historically been treated as a compliance activity. You test to avoid legal exposure. You put a seal on the label to satisfy retail buyers. You archive the certificates of analysis in a folder nobody opens.

That model is becoming obsolete. Function's platform turns verified testing data into a consumer-facing asset. When a product's TrustScore and lab results are embedded in a platform that millions of health-conscious consumers use to manage their biomarkers, that verification becomes a direct-to-consumer conversion tool.

Think about what that means for retail. A brand with verified, outcome-linked data doesn't just satisfy a buyer's compliance checklist. It gives the retailer a story to tell on shelf and in digital listings. It reduces return rates. It generates the kind of earned credibility that no advertising budget can replicate directly.

For brands targeting premium positioning, this matters enormously. The consumers who spend the most on supplements are the same consumers most likely to be using platforms like Function. They're tracking their health with real data. They're not satisfied with marketing claims. They want proof.

What This Means for Your Brand Strategy

If you're running a supplement brand, this acquisition reshapes how you should be thinking about verification investment. Here's the operational reality:

ISO 17025-accredited testing is the new floor. Basic third-party certification is no longer sufficient differentiation. Accredited lab verification tied to a recognized scoring system is what premium retail buyers and digital health platforms will expect.
Data needs to be consumer-accessible. Lab reports buried in a compliance folder don't drive conversion. Verification data embedded in the platforms your customers already use does. That's the integration Function is building.
Biomarker linkage is the next frontier. The most defensible brand position in the next five years will belong to supplement companies that can demonstrate measurable outcomes in real consumer health data. That requires partnerships with platforms that hold that data.
Plant-based sourcing requires deeper audit trails. If you're formulating with botanical ingredients, your supply chain documentation needs to be robust enough to withstand ISO-level scrutiny. That investment pays back in premium pricing and retail access.
Subscription retention improves with verified outcomes. Brands operating subscription models have the most to gain from outcome-linked verification. When consumers see their biomarkers improve alongside a product they're taking, churn drops significantly.

That last point connects to a broader pattern in health and wellness monetization. Subscription models built on demonstrable outcomes outperform those built on habit alone. The mechanics of that dynamic are explored in detail in subscription pricing models that actually work for recurring revenue in 2026, and the logic applies directly to supplement brands moving toward outcome-tied retention strategies.

The Broader Signal for the Supplement Industry

Zoom out and the picture is consistent. Consumer expectations around health product transparency are rising across every channel. Strength training is 2026's top health priority according to current consumer data, and the supplement products that support performance and recovery are under increasing scrutiny from buyers who take their training seriously.

These consumers are not passive. They read labels. They cross-reference ingredients. They share reviews. They distrust vague claims and reward specificity. Function's platform, now augmented by SuppCo's verification infrastructure, is designed exactly for this consumer profile.

The broader FMCG sector has already read the signal. Unilever's acquisition of Grüns placed a major corporate bet on the greens supplement category precisely because consumer demand for transparent, functional nutrition is real and growing. That kind of institutional capital doesn't move on trends. It moves on structural shifts.

The Function-SuppCo acquisition is that kind of structural shift. Transparency has moved from a marketing differentiator to a market infrastructure requirement. The brands that invest in verified, outcome-linked proof systems now will hold a durable advantage in a market heading toward $284 billion. The brands that treat testing as a checkbox will find that the checkbox is no longer enough to get through the door.
