Au revoir, arthritis.

Bullfrog partnered with Interpath to launch Epijoint®, a joint pain relief supplement designed to liberate people from the limitations of mild osteoarthritis. Our challenge: overcome deep scepticism in a category filled with broken promises and tired advertising.

By defining a credible brand, co-creating a digital experience with the community, and building a distinctive campaign around the proposition “Move how you feel”, we gave people a reason to believe again, and drove results fast.

IMPROVEMENT IN QUALITY OF LIFE SCORES FOR CUSTOMERS

Phase 1:

Defining the brand

We positioned Epijoint® as a trusted, liberating solution to the limitations of osteoarthritis. A calming colour palette, dynamic flexible visual elements were inspired by the customers needs for a sympathetic solution that worked. A close link between pack design and brand mark created instant recognition and credibility. The identity signalled quiet confidence, the opposite of the overpromising category norms.

Phase 2:

Elevate the product

We positioned Epijoint® as a trusted, liberating solution to the limitations of osteoarthritis. A calming colour palette, dynamic flexible visual elements were inspired by the customers needs for a sympathetic solution that worked. A close link between pack design and brand mark created instant recognition and credibility. The identity signalled quiet confidence, the opposite of the overpromising category norms.

Phase 3:

Share your brand story

At the heart of our work was the promise: “Move how you feel.” Rooted in research and community insight, this proposition reframed Epijoint® as a way to reclaim freedom and expression, not just relieve symptoms.

We brought it to life through the Blacksmithery campaign, telling the irreverent story of Patricia, a septuagenarian who returned to her passion for blacksmithing once freed from pain. This playful, human story stood out in a sea of generic category advertising, while embodying the emotional power of the “Move how you feel” platform.

Phase 4:

Optimise for conversion

We scaled impact by reinforcing value, surfacing proof points, and highlighting research-backed claims to build trust. Every touchpoint, from packaging to Chemist Warehouse activity reinforced credibility and made purchase simple.

The result: a brand that turned disbelief into devotion, and a product that sold out in its very first month.
