For health platforms & fitness chains
Stacked gives health apps, longevity platforms, and fitness chains a white-label API to recommend, price, and fulfill evidence-based supplements — without building it themselves.
Molecule pricing API
GET /v1/products?molecule=creatine
{
"molecule": "creatine monohydrate",
"price_per_g": 0.0042,
"sources": [...],
"interactions": ["phenytoin"],
"examine_score": 8.3
}The problem
No unified European distributor. Platforms must manage 4–6 supplier relationships just to stock a basic stack.
US platforms like Fullscript have no European presence and no API access. Health apps cannot integrate supplement fulfillment.
End users cannot compare supplements by molecule. Price per active gram is invisible — making trust and conversion hard.
EFSA claims,跨境 compliance, country-specific rules — too complex for any single platform to navigate alone.
The solution
Stacked is the infrastructure layer between supplement science and end-user conversion. We handle the database, the fulfillment, and the compliance — you bring the audience.
Every product indexed by active ingredient. Price per gram, interaction flags, examine.com scores. Structured, not scraped.
Embed supplement recommendations, protocol management, and checkout flows directly in your app — under your brand.
One order, one delivery. Consolidated inventory from EU- certified warehouses. No more managing six supplier accounts.
Health claims pre-validated against EU regulations. Your app stays compliant, your users stay safe.
GTM Channels
We don't need thousands of B2C customers. We need 3–4 fitness chains or health app publishers to sign.
€5,000/mo
Integrate our recommendation engine and product catalog via API. Your users get science-backed stacks; you get a new revenue line.
€300/mo per gym
White-label supplement feature inside their member app. One integration serves thousands of active users without their own supply chain.
€500/mo
SaaS tool for prescribing personalized stacks. Combined with training programs — stickier, higher lifetime value.
Developer-first
Clean REST endpoints. Structured product data. Interaction checking built in. Ship the integration in days, not months.

€300–€5,000/mo
Access to API, white-label UI components, recommendation engine, and compliance database. Tiered by volume and feature set.
8–12%
On the gross merchandise value of supplements fulfilled through the platform. Aligned incentives: we grow when you grow.
€200kby year 1
4 app publishers × €5k/mo + 20 gym locations × €300/mo + coaches = realistic, non-heroic growth.
Fullscript processed $1B+ in the US. No one has built the equivalent for European health platforms. Stacked is the infrastructure layer — the boring, defensible, high-margin kind that makes sense once you see it.
Built for platforms. Powered by science. Deployed in Europe.
