World's only API & MCP-first supplement company

Supplement manufacturing,
built for developers and AI agents.

We're the only supplement company offering a true API-first platform — and the first with a Model Context Protocol (MCP) server. Build custom checkouts, integrate with your EHR, or let AI agents formulate, order, and fulfill packs autonomously.

API-First

Every capability — formulation, ordering, fulfillment, tracking — exposed as a clean REST API. No legacy dealer portals.

Coming Soon

MCP Server

The first supplement MCP server. Plug OK Capsule directly into Claude, ChatGPT, and any agentic workflow.

Coming Soon

Agent-Ready

AI agents can design, validate, and ship personalized supplement protocols end-to-end — programmatically.
