Case in 60 seconds

VitaHealth was launching its new Asta-Glutathione formula into the supplements category, where people research, hesitate and buy on trust rather than impulse, so a single launch-week spike would fade before the purchase decision was made.

SushiVid treats the supplement purchase as a slow decision formed through repeated, trusted exposure, so the campaign turns on duration and credibility rather than launch-week volume, because potential buyers sit at different points in their consideration at any given time.

The organising thesis was a sustained review programme long enough for creators to speak to real, ongoing use rather than a one-off unboxing, with personal promo codes turning that credibility into sales accountability for each creator.

SushiVid ran a three-month programme in which 10 influencers reviewed VitaHealth's new Asta-Glutathione formula, each carrying a personal promo code, with the reviews spaced across the full three months so the brand stayed present through the consideration period.

SushiVid reports that over the three months the campaign reached 1.8 million people and generated 221,000 views, and says the promo codes gave VitaHealth visibility into which creators drove purchases, although the page publishes no sales figure.

Strategy Breakdown

Potential supplement buyers who research and hesitate before purchasing, reached at different points in their consideration.
Supplements are researched and bought on trust rather than on impulse, so the page treats a short burst of launch content as insufficient because it fades before the decision is made.
The brand's role was to stay present and credible across the whole decision arc, while personal promo codes tied the awareness creators built to tracked purchases.
SushiVid says supplement decisions form through repeated, trusted exposure, which is why the reviews were spaced across three months to catch potential buyers at different points in their consideration.

Why SushiVid's strategy worked

  1. 1

    For a considered purchase such as a supplement, spreading reviews across months rather than concentrating them in launch week keeps the brand in view while buyers move through research and hesitation at different times.

  2. 2

    Per-creator promo codes make each voice accountable for sales rather than impressions, which gives a brand a basis for judging which creators actually move purchases on a sustained programme.

  3. 3

    A review window long enough to cover ongoing use lets creators speak from experience rather than first impressions, which carries more weight in a category that people buy on trust.
