Does dropshipping work for supplements in the GCC?
It works where the buyer is patient and the item is hard to compare on price. It fails where either of those is untrue — and the second is untrue for anything with a barcode.
Where it works and where it does not
The test worth running before committing: can the customer find the identical item elsewhere in under a minute? If they can, the competition is on delivery speed and price, and a dropshipper controls neither.
Dropshipping trades margin for not holding stock, and the trade only works while traffic is cheap. For a supplements and health store in the GCC, the answer turns on one thing in particular: Subscription behaviour without a subscription: people finish a tub and reorder, often on the same day of the month.
What is different about the GCC
The GCC is not one market. Payment habits, delivery norms and language expectations differ enough that a single approach underperforms in at least one country.
Payment preference varies by country more than most planning assumes.

The part nobody plans for is returns: if the supplier will not take one back, the store is the returns department.
Where a mobile app comes into it
Reorder reminders are the whole opportunity, and they are free through an app and paid through anything else.
