The Shopify subscription app built for supplement brands.

Why supplement subscriptions are their own problem

A supplement bottle is a 30-day unit, and results depend on not missing a day. That makes the subscription the product experience, not just a discount: the whole point is that the next bottle arrives before the current one is empty, so the regimen never breaks.

Supplements also sell as stacks, not single SKUs — a base plus add-ons a customer builds over time. So build-your-own selection and multi-product bundles matter, and because the category runs on repeat volume, a tool that takes a percentage of every recurring charge is a direct tax on the model that makes supplements profitable.

What you can run

Built on Shopify's native rails

Every recurring charge runs on Shopify Subscription Contracts and Shopify's own checkout — there's no third-party billing processor, no redirect, and Curobi never touches or stores card data. Your reviews, loyalty, email/SMS, and analytics apps see subscription orders exactly the way they see any other Shopify order. It also keeps your products on the same native product and checkout layer Shopify exposes to its agentic-commerce and AI shopping features, instead of behind a proprietary widget those agents may not read.

Setting up a supplement subscription

1. Create replenishment plans

   Set cadences that match the dose (a 30-, 60-, or 90-count bottle depletes on its own schedule) and any subscribe-and-save discount, and apply them to your products or variants.

2. Add the purchase-option widget

   The widget renders inside your existing theme so shoppers can buy once or subscribe from the same product page — no separate checkout or redirect.

3. Set the cutoff for stacks and bundles

   For build-your-own stacks, set the cutoff so each selection is locked before the recurring charge and before fulfillment.

4. Turn on the portal and recovery

   A self-service portal (skip, pause, adjust the stack, change frequency) and automatic failed-payment recovery are included, so customers manage their regimen without emailing support.

Keeping supplement subscribers (reducing churn)

The biggest churn drivers in supplements are bottles piling up when someone doses less often than expected, wanting to adjust the stack, and failed payments that silently cancel customers mid-regimen. Curobi counters each — a self-service portal to skip, reschedule, or change frequency so bottles never stack up, build-your-own stacks so a customer adjusts instead of leaving, save flows that offer a pause instead of a cancel, and automatic dunning that retries declined cards before a regimen lapses. Keeping a customer on the protocol through a skip beats re-acquiring them — see churn for why.

Switching from another app

Moving off a tool that takes a cut of every recurring charge is free: Curobi provides CSV-based migration from Recharge, Appstle, Loop, Bold, or Seal without interrupting active subscriptions. Compare the specifics: vs Recharge, vs Appstle, or vs Loop.

Supplement brands FAQ

Is there a Shopify subscription app for supplement brands?

Yes. Monthly replenishment, build-your-own stacks, bundled protocols, and prepaid regimens are all native features in Curobi. With 0% transaction fees and CSV migration from Recharge, Appstle, Loop, Bold, or Seal on the Pro plan, it fits supplement brands that run high-repeat replenishment and don't want a percentage taken from every recurring charge.

Can customers subscribe to a stack of multiple products?

Yes. Customers can build their own recurring stack from your eligible products, or you can sell a fixed multi-product protocol as a single bundle that ships together on one cadence and one price. Either way the whole regimen is managed from one customer portal, so a subscriber can adjust the stack without cancelling.
