Smartkid is an Istanbul-based digital marketing agency that grows online sales for food supplement and vitamin brands. The defining constraint in this category is regulation: a food supplement cannot claim to treat, prevent or cure a disease. Advertising platforms reject such claims automatically as well. That is why growth for supplement brands does not come from bolder sentences, but from writing the right sentence and systematizing repeat purchase. Our work with Fema Farma is our published case study on how supplement and health brands scale.
The limits of marketing in food supplements are clear: the product is not a medicine, and promising treatment is prohibited. That constraint is actually an opportunity — because most competitors either push the line and get their ads rejected, or write generic copy that says nothing at all. The right path is to build language that clearly explains what the product contains, how it is used and who it suits, and to build sales on repeat purchase.
At Smartkid we know that profit in food supplements comes not from the first sale but from the customer who uses your product regularly. And building a compliant narrative is the precondition for winning that customer.
In this category the wrong agency choice means more than a wasted budget: it creates the risk of a suspended ad account and of non-compliance. Ask your candidate: do you know the claim limits in food supplement regulation, do you have experience resolving rejected ads, can you build subscription and repeat-purchase models, and do you have published work in this category?
We package our services around three needs: a compliant narrative, sustainable customer acquisition and a repeat-purchase system. When all three are built together, the category's constraints stop being an obstacle and turn into a competitive advantage.
We build visibility on ingredient, usage and need-based searches. With guide content and the right product page architecture we bring users still in the research phase together with your brand — search is the channel least affected by advertising restrictions.
We build trust through educational content, usage explanations and expert collaborations. We keep content inside regulatory limits and make sure collaborations are transparently disclosed as advertising.
We structure Google and Meta campaigns by need segment, and prepare creative and landing pages in line with platform policies to lower rejection risk. We manage budget against the subscribing customer rather than the one-off sale.
