i-Health hired Dentsu

2026 · Consumer health / OTC women's and gut health

i-Health's brands were trusted but not part of anyone's daily routine, and that is where the category's growth was going.

Somebody said so

Somebody asserted the problem rather than a document recording it. Who said it, and whether they had a stake, is named below.

How we know

"Our brands are extremely well trusted. But we were losing out on being brands that consumers want to introduce into their everyday lifestyle. That's where the growth in these categories is coming from."

Who says so	Amanda Hines, i-Health's own chief marketing and innovation officer for North America, in Adweek. MediaPost, LBB and the agency's newsroom all carry the appointment. Read it
A second source	MediaPost reported on 11 February 2026 that Dentsu had been named media and creative agency of record for i-Health, listing Culturelle, AZO and Estroven. LBB and Dentsu's own corporate newsroom carried the same appointment and the competitive review.
What the agency was asked to do	Not published as a quoted brief. On record: the appointment covers i-Health's full US portfolio across brand strategy, media planning and buying, creative, social, influencer, and measurement and technology.
How the agency was picked	Competitive pitch
How that happened	Adweek states the appointment was awarded after a competitive pitch. Dentsu's own account adds that i-Health had already worked with dentsu and expanded the relationship, and that the search was prompted by an internal restructure to reduce fragmentation. Rival agencies are not named.
How long it took	Announced 10 February 2026. New creative expected in the second quarter of 2026. Pitch length and contract length not published.
Recorded as	i-Health (AZO, Estroven, Culturelle) (DSM-Firmenich)

Watch out for: The word influencer is one item in a long integrated remit that is mostly media and creative. The richest detail, including the Hines quotes, comes from dentsu X's own insight page, so treat the reasoning as the agency's telling. Adweek independently confirms the pitch and the influencer line. The 2 million dollar spend figure is a COMvergence estimate, not a disclosed budget.

← Every case

Every case here carries the one link that proves it, and names who said it. Where that is the agency describing its own win, the card says so rather than hiding it. Cases where nobody ever documented a reason are not on this page at all. Brought to you by Influencer Advisory, your influencer marketing partner for supplement, health and beverage brands.
