The Brief
Supplements are a considered purchase — people research, hesitate, and buy on trust, rarely on impulse. So for the launch of its new Asta‑Glutathione formula, VitaHealth needed sustained, credibility‑building content over time, not a single launch‑week spike that fades before the decision is made.
The Approach
SushiVid ran a three‑month programme with 10 influencers reviewing the new formula — long enough for creators to speak to real, ongoing use rather than a one‑off unboxing. Each carried a personal promo code, so the brand could track exactly which creators were driving actual sales, not just impressions.
The Execution
Spreading content across three months let the message build credibility the way supplement decisions actually form — through repeated, trusted exposure. The per‑creator promo codes turned that credibility into accountability, tying awareness directly to purchase and revealing which voices genuinely moved the needle. Spacing the reviews across the full three months also kept the brand present through the whole slow arc of a supplement decision, catching potential buyers at different points in their consideration rather than all at once.
The Results
Over the three months, the campaign reached 1.8 million people and generated 221,000 views, with promo codes giving VitaHealth clear visibility into which creators drove real purchases.
The Takeaway
High‑consideration products need patience and proof. A sustained programme builds the trust a supplement purchase requires, and trackable codes tie that trust to sales you can measure. The lesson: for considered categories, run long, build credibility over time, and attribute rigorously so you know what's actually working.
