Answer
How often do customers reorder supplements?
Most supplement customers reorder every 30 to 90 days, set by container size and daily dose. A standard 30-count or 60-count bottle taken once or twice daily runs out in roughly 30 to 60 days, so the natural reorder window aligns with when a customer physically runs out of product.
How often do customers reorder supplements?
Most supplement customers reorder every 30 to 90 days, set by container size and daily dose. A standard 30-count or 60-count bottle taken once or twice daily runs out in roughly 30 to 60 days, so the natural reorder window aligns with when a customer physically runs out of product.
The exact cadence depends on the format. A 30-day bottle taken once daily empties in about a month. A 60-count bottle dosed twice daily also lands near 30 days, while the same bottle at one capsule a day stretches to roughly 60 days. Larger 90-count or 120-count value sizes push the reorder window out to two or three months. Powders, gummies, and liquids vary more widely depending on serving size and how consistently the customer uses them.
Adherence is the biggest variable. Customers who miss doses, skip weekends, or share a bottle across a household run out later than the label implies. This is why fixed-interval assumptions often miss: two customers who bought the same product on the same day can run out weeks apart. Reorder timing that reflects each customer's actual consumption pace is more accurate than a single brand-wide average.
What drives reorder timing for supplements
Three factors set the per-customer reorder window: serving size (capsules or scoops per day), container count, and adherence. Multiplying dose by days gives a baseline depletion date, but real behavior shifts it. New customers building a habit tend to use product less consistently than long-term users, so early reorders skew later than the math predicts. A large share of buyers also lapse before a second purchase — across DTC, repeat purchase rates run well below half, with a median near 19% — which makes well-timed reorder prompts especially valuable in the first cycle.
How reOtter helps
reOtter predicts each customer's run-out date per SKU based on what they actually bought and how they consume it, then prompts a reorder right before they run out — through a one-click reorder page rather than a generic discount blast. The merchant sets the timing rules; the engine does the per-customer math.
Key takeaways
- Typical supplement reorder windows run 30 to 90 days, driven by container size and daily dose.
- A 30-count once-daily bottle empties in about a month; larger value sizes stretch to two or three months.
- Adherence shifts real run-out dates, so per-customer timing beats a single brand-wide average.

Frequently asked questions
- How long does a 60-count supplement bottle last?
- A 60-count bottle taken twice daily lasts about 30 days; at one capsule per day it stretches to roughly 60 days. Missed doses extend it further, which is why real run-out dates vary by customer even for the same product.
- Why do supplement customers stop reordering?
- Most lapse because nothing reminds them at the moment they run out. Without a prompt timed to their actual depletion, the reorder slips and they drift to a competitor or stop entirely. Inconsistent adherence also makes generic fixed-interval reminders miss.
- Is a subscription better than reorder reminders for supplements?
- Both work, and the strongest brands run them together. Subscriptions suit committed daily users; reorder reminders capture customers who want to stay in control of timing and would cancel a fixed cadence. Offering both captures more repeat revenue than either alone.
- What's the best time to send a supplement reorder reminder?
- Shortly before the customer's predicted run-out date, based on their specific dose and container size rather than a brand-wide average. Prompting a few days early gives them time to reorder before they're out, reducing gaps in usage.
