Health Supplements
Supplements are bought once and paid for over months.
Acquisition cost that looks indefensible on the first order can be the right price for a customer who reorders for a year. It can also be a disaster. The only way to know is your own cohort data.
Why this changes the advertising decision
What is different here isn't the channel. It's the economics underneath it.
Payback is a cohort question
A first-order target either caps growth or hides losses, depending on the product. Neither is a decision you want made by default.
Reorder rates differ sharply by product
Daily-use products and occasional-use products cannot share an acquisition target, however similar the margin looks.
Claims are constrained
What you can say is regulated, which restricts the queries and assets available and changes what competing for attention actually costs.
Cash pays before the customer does
Spending against twelve-month value requires the cash to cover the gap. Payback period is a real constraint, not a modelling detail.
One product, one decision
The decision looks like this.
Illustrative example. Not a client result.
Daily magnesium, 90 capsules
- Contribution, first order
- Thin
- Reorder cycle
- Roughly quarterly
- Cohort payback
- Months, not days
- Cash cover
- The real constraint
What changed
Cash cover tightened before payback completed.
The LTV case for scaling was sound. The cash case was not, so the job changed until it was. That is a human decision, made with you.
Nothing here happens automatically. The data flags the change; the job change is a decision we make with you.
What we do about it
The execution follows the economics, not the other way round.
Targets are set on measured cohorts
Repeat purchase is read from your order data over a defined window and stated openly, rather than taken from a platform LTV model.
Payback period is treated as a constraint
Spending ahead of cash is a decision you make deliberately, with the cash gap visible, or not at all.
Compliance shapes the query set
Claim constraints are built into what we compete for, rather than discovered when something is disapproved.

Wilsons Pet Food
Customer lifetime value, measured on subscription cohorts rather than modelled in the ad platform.
Pet food rather than supplements, but the same economics: a consumable bought on repeat, where lifetime value measured on real cohorts changed what acquisition was worth.
- Period
- Year on year, after the commercial restructure.
- Basis
- Contribution measured after COGS and shipping. Lifetime value measured on subscription cohorts, not modelled in the ad platform.
- Source
- Client account and subscription data, client-reported.
The Method - BOI®
How BOI® applies here.
The problem
Repeat purchase dominates supplement economics, and bidding to a single first-order target ignores it entirely.
The BOI® answer
Subscription-eligible SKUs run as Scale against measured cohort value. One-off purchases run as Profit. Trial sizes run as Gateway.
Next step
We'll tell you what your account is doing to your health supplements margin.
A commercial review reads your account against your own product economics, and tells you where the next pound should go. Brands we work with typically spend around £10k a month on Google Ads, but that is guidance, not a gate. If you are below it and the question is real, ask anyway.
