Health and wellness influencers on Instagram, TikTok and YouTube included a product or service promotion in 38% of their posts during a three-month stretch this spring, according to a Pew Research Center analysis published this week.
The study also found that most people who follow this content end up spending money or changing their habits because of it.
What the data shows
Pew examined 535,512 posts published by 6,334 health and wellness influencers from February to April 2026 , looking specifically at who recommends products and what kinds of products show up most often.
Among the posts that contained a recommendation, the most common promotion category is informational resources, cited in 45% of these posts , making information products the single most common type of pitch. Roughly a third of posts promoted physical products such as supplements, skincare or fitness gear.
The free guide has become a particularly common hook, with free offers appearing most often among posts that promote physical products, according to Pew’s analysis.
That free download or email signup often functions as the first step toward a paid relationship between creator and follower, similar to the way lead magnets work across other corners of the internet, including the forums and groups Pew has previously mapped in its hobby and interest community research.
Most creators sell something eventually
The reach of these promotions is broad. A companion Pew report released in October found that about 92% of the influencers made at least occasional promotional appeals, and roughly a third did so in at least half their posts .
Pew’s methodology counted both paid sponsorships and free offers in that tally, since posts that contain a promotion include those that recommend both paid and free products and services . Those figures describe the content Pew analyzed, not the share of all social media health posts or the quality of any promoted product.
Not every influencer promotes at the same rate. Promotions appeared in about two-thirds of posts about supplements and over-the-counter medications , a far higher rate than other categories.
Influencers who described themselves as health care professionals discussed conditions, mental health and supervised treatments more often than those without a stated medical background , with health and wellness influencers tending to recommend products and services that align with their professional backgrounds .
Followers often act on the pitch
The commercial content appears to translate into real spending. Among people who get health and wellness information from influencers, 55% say they have bought a health or wellness product after encountering it.
That follow-through pattern tracks with broader consumer research on influencer marketing. A separate industry survey from PYMNTS Intelligence found that among consumers who have bought an influencer-recommended product, 95% said they usually do additional research before buying, often consulting more than one source .
That mirrors the deliberate, delayed-purchase behavior GCN has reported among online shoppers who pause before checking out, as seen in cart abandonment research showing a waiting period can change how buyers feel about a purchase.
Why it matters
The methodology limited the analysis to individual influencers with at least 100,000 followers on one of the three platforms, primarily English-language content, a U.S. audience and posts about health or wellness during the study period , so the figures describe a slice of the largest wellness creators rather than the entire influencer economy.
Still, the scale of the sample, more than half a million posts, offers one of the most detailed looks yet at how often health advice online doubles as a sales pitch, and how often followers end up opening their wallets as a result.
