Active Iron is a well-known Irish brand specialising in science-backed iron supplements for women. As the brand set out to expand into the United Kingdom and United States, it engaged Terrier Agency to build awareness through authentic voices in the female health, fitness and lifestyle space.
We ran a large-scale outreach campaign targeting thousands of female creators across both markets, securing the participation of 1,000 influencers. Each received Active Iron supplements to test over several weeks before documenting their genuine experiences. The programme generated 556 pieces of content with a combined creator following of 9,170,423.
The volume of authentic, lived-experience content significantly heightened awareness of Active Iron in two markets where the brand previously had limited recognition.
Proving a Supplement Works Over Several Weeks, Not One Post
An iron supplement can’t be judged from a single photo of the bottle — the claim only means something once someone has actually taken it for a while. Active Iron’s brief reflected that: 1,000 influencers across the UK and US received product to test over several weeks before posting, rather than being asked for a same-day unboxing, so every piece of content that followed came from a creator who had genuinely used the product long enough to have an opinion on it.
What 9.17 Million Combined Following Built Across Two Markets
A combined creator following of 9,170,423 is an exposure figure across two new markets, not a sales number for a supplement brand still building recognition outside Ireland. What it demonstrates is scale of authentic, lived-experience content rather than a single hero campaign: 556 separate pieces from 1,000 creators across the UK and US female health, fitness and lifestyle space, each one a genuine account rather than a paid claim repeated at volume.
