Subscription models: recurring revenue with supplements

Reviewed by Dr. Daniel Wallerstorfer, molecular biologist and founder of Novogenia · Updated: 11 October 2026 · Reading time: 8 min

In short

Supplements are taken every day and run out at a predictable point – ideal conditions for a subscription with automatic reorder. What matters is the delivery rhythm (30 or 90 daily servings), billing, good customer care between deliveries and clear information before the contract is concluded. Personalized products add one more advantage: the formula can be updated with every new production run.

Why supplements and subscriptions go together

A supplement is taken every day. That means it is clear from the outset when a pack will be used up – after 30 or after 90 days. Few product categories are as well suited to a subscription with automatic reorder:

For your customers: the next box arrives on time without anyone having to remember. Daily use continues without a gap.
For you: a single sale becomes a lasting customer relationship. Ideally, every customer you win brings in revenue for months or years.
For planning: if you know how many boxes are due over the coming months, raw materials, packaging and production can be planned ahead – avoiding both shortages and overstock.

This is especially clear for companies that sell analyses: a genetic test or a blood test is bought once. A supplement matched to it is consumed and reordered – the analysis becomes the start of an ongoing customer relationship. That is the core of recurring revenue with supplements.

Subscription types at a glance

Not every subscription works the same way. These basic types are common and can be combined:

Type	How it works	What to watch
Automatic reorder on a fixed rhythm	The next box is automatically produced, shipped and billed.	clear information before every delivery
Flexible subscription	Customers can postpone or pause deliveries or switch pack sizes.	more effort in your shop and service, but fewer cancellations
Subscription with a minimum term	Customers commit for a set period.	check national rules on duration and cancellation; can deter new customers
Prepayment for several deliveries	Several boxes are paid for at once and delivered one after another.	good for cash flow; the product still has to convince throughout

The rhythm: 30 or 90 daily servings?

The pack size sets the pace of your subscription – and with it costs, touchpoints and cancellation risk:

Criterion	30 daily servings	90 daily servings
Cost per serving	higher	lower – more cost-effective
Price per delivery	low entry point	a larger amount at once
Shipments per year	more shipping and packaging	less shipping and packaging
Touchpoints	frequent – every delivery is a chance to engage	less frequent – care between deliveries matters more
Occasions to cancel	more frequent, because every charge prompts a decision	less frequent

Many brands use both: 30 daily servings as a low-threshold entry and 90 daily servings for customers who already know the product. More on packaging in Packaging.

Billing: do it yourself or via the manufacturer?

There are two basic models for running a subscription:

Billing via the manufacturer: the manufacturer handles reorders, billing and shipping. You don’t need to build your own subscription technology and can focus on brand, sales and customer care.
Your own billing with a fulfillment partner: you bill through your own shop or system and pass the orders to the manufacturer, which produces and ships directly to your customers. This fits if you already have subscription infrastructure or want to bill several products together.

In both cases, clarify early how order data, address changes, pauses and cancellations flow between you and the manufacturer – and who is the first point of contact for delivery questions.

Personalized products on subscription

With personalized supplements, a subscription is more than a repeat delivery. At Novogenia, the formula is recalculated for every new production run. Reasons the composition can change:

the customer’s age, which is recalculated from the date of birth for every production run,
an updated diet and lifestyle questionnaire,
new analysis results, genetic or from blood,
changes in health status reported by the customer,
new scientific findings.

For your business model, this is a strong argument: a new blood test or an updated questionnaire leads directly to an adjusted formula. Explain to your customers from the start that the composition may change for these reasons – otherwise a box that looks different will prompt questions.

Retention: levers against cancellations

A subscription is only as valuable as it is long-lasting. Most levers are not discounts but good customer care:

A good start: with the first delivery, explain how to take the product and what is in it – factually and without health promises.
A reminder before each delivery: a message before every charge avoids surprises and complaints.
Flexibility: customers who can postpone or pause a delivery cancel altogether less often.
Easy self-service: address, payment method and delivery date should be changeable without a phone call.
Failed payments: expired cards or bounced charges end many subscriptions unintentionally. Plan a process that reminds customers in a friendly way.
Contact between deliveries: especially with 90 daily servings, useful content helps keep your brand top of mind.
Ask why: briefly ask for the reason with every cancellation. You will learn more from that than from any survey.

Metrics to keep an eye on

Metric	What it tells you
Churn rate	how many subscriptions end per period
Retention after the first and second delivery	whether your onboarding convinces – the most critical phase of a subscription
Customer lifetime value	how much revenue a customer brings in on average
Customer acquisition cost	whether your advertising pays off relative to customer value
Failed payments	how many subscriptions are at risk for technical reasons

In a pilot in particular, it pays to track these figures cleanly from day one – more on this in Starting small: minimum order quantities and pilots.

Transparency instead of a subscription trap

A subscription that feels like a trap costs you more than any cancellation: complaints, chargebacks and bad reviews. So make it clear from the start what your customers are signing up for:

Clearly recognizable as a subscription: one-time purchase and subscription are clearly separated, and nothing is pre-ticked.
Price and rhythm at a glance: what each delivery costs and when the next one is due.
Cancelling as easy as ordering: customers who know it is easy to leave find it easier to sign up.

Legal framework: basic rules for subscriptions

Subscriptions sold to consumers are subject to consumer law. In the EU, the Consumer Rights Directive (Directive 2011/83/EU) sets basic rules for distance contracts, which the member states transpose into national law:

Topic	What it means for your subscription	Legal basis
Pre-contractual information	For subscriptions, the total price includes the total costs per billing period; the duration of the contract or the conditions for terminating it must also be stated.	Art. 6, Directive 2011/83/EU
Order button	The button must be easily legible and labeled “order with obligation to pay” or with a corresponding unambiguous formulation.	Art. 8, Directive 2011/83/EU
Right of withdrawal	14 days for distance contracts; for the regular delivery of goods over a defined period, the period starts when the consumer receives the first good.	Art. 9, Directive 2011/83/EU
Exceptions to withdrawal	among others, for goods made to the consumer’s specifications or clearly personalized, and for sealed goods that are not suitable for return due to health protection or hygiene reasons once unsealed after delivery. Have an expert check whether this applies to your product.	Art. 16, Directive 2011/83/EU
Withdrawal function	For distance contracts concluded via an online interface, consumers must also be able to withdraw using a withdrawal function; applicable from 19 June 2026.	Art. 11a, inserted by Directive (EU) 2023/2673

Beyond that, many countries have their own rules on how long minimum terms may be, how subscriptions renew automatically and how easy cancellation must be. Check the consumer-law rules in your target market and have your subscription terms reviewed by an expert before you launch.

Frequently asked questions

Why are supplements well suited to a subscription?

Because they are taken every day and run out at a predictable point. A subscription with automatic reorder ensures your customers never have a gap – and gives you predictable, recurring revenue instead of one-off sales.

Is a subscription with 30 or 90 daily servings better?

Both have advantages. 30 daily servings lower the entry price and create more touchpoints, but mean more shipments. 90 daily servings are more cost-effective per serving, save on shipping and give customers fewer occasions to cancel. Novogenia offers a 90-day subscription with automatic reorder.

Who handles subscription billing when I work with Novogenia?

You have two options: billing runs via Novogenia, or you bill through your own system and Novogenia handles production and shipping as your fulfillment partner.

Does a personalized formula change during a subscription?

Yes, by design. At Novogenia, the formula is recalculated for every new production run: at least with the current age, and with an updated questionnaire or new lab results where available. Explain to your customers from the start that the composition may therefore change over time.

What legal rules apply to a supplement subscription?

In the EU, the Consumer Rights Directive (Directive 2011/83/EU) sets rules on, among other things, pre-contractual information, the wording of the order button and a 14-day right of withdrawal for distance contracts. Many countries have additional rules on contract duration, renewal and cancellation. Check the rules in your target market and have your subscription terms reviewed by an expert.
