Top supplement ads in Belgium
We found 50 supplement ads from 33 brands whose main market is Belgium and that ran for 60 days or more on Facebook and Instagram. Brands only keep paying for ads that sell, so a long run is the best public sign that an ad works.
Half of them ran longer than 68 days, longer than the 67-day median for supplement ads across Europe, and 8% passed six months. The longest has been running for 256 days.
Most run on Facebook and Instagram (98%). The median ad text is 63 words long, and 54% use emoji. NovoVita. has the most long-running ads here (9), followed by Amacx Sports Nutrition and Fuelyourbody.

How we count
Every night adthief.ai collects the Meta ads running in the EU and the UK and keeps the ads that have run for 60 days or more, one per creative. An ad counts for its main market, the country where it reached the most people. Markets and industries with fewer than 50 such ads get no page. Meta doesn’t publish spend or sales, so a long run stands in for “profitable”: a strong signal, not a guarantee. Data as of 3 November 2026.
