In July 2026, the FTC approved a final order against TruHeight, a Nevada-based supplement company that marketed height-growth products to kids and teens with claims like "The Only Supplement Clinically Proven to Help Height Growth." The company had no competent scientific evidence to back that claim. It also had thousands of fake five-star reviews written by employees, vendors, and incentivized customers, plus bot-run fake social profiles. The judgment was $4 million, suspended to a $750,000 payment based on the company's inability to pay, along with a permanent ban on unsupported health claims and fake reviews.
That case, plus a June 2026 FTC suit against Amare Global Holdings over claims that supplements could treat depression, anxiety, and ADHD, and a March 2025 wave of joint FDA and FTC warning letters to ten companies over diabetes claims, tells you something specific about where enforcement attention is right now. It is not aimed at supplements generally. It is aimed at disease claims dressed up as wellness claims, and at reviews used as fake evidence. If you are marketing a supplement brand in 2026, both of those are marketing decisions, not just legal ones. Here is how to grow without becoming the next case study.
Why Is the FTC Cracking Down on Supplement Marketing Right Now?
The FTC is targeting two specific failure points: unsubstantiated health claims and fake or incentivized reviews, and recent cases show it is treating them as separate violations, not one combined issue. TruHeight was penalized for both the height-growth claim itself and for the fake review network built to support it. Amare Global Holdings is being sued for allegedly telling parents and adults its supplements could boost serotonin and dopamine and lower cortisol enough to treat depression, anxiety, and ADHD. Notably, the FTC also filed a contempt motion against a former Chief Science Officer who was already bound by a prior 2005 FTC order, meaning past enforcement history follows individuals, not just companies.
The standard behind all of this comes from the FTC's Health Products Compliance Guidance: any health-benefit claim needs "competent and reliable scientific evidence," which in practice means randomized controlled human trials. Epidemiological evidence only counts as a substitute in narrow cases where a trial genuinely isn't feasible. If your marketing team is writing copy that implies a clinical outcome and you cannot point to an RCT behind it, that copy is a liability, not just a growth lever.
What Health Claims Can You Actually Make About a Supplement?
You can make structure/function claims about how an ingredient supports the body, but you cannot claim your product treats, cures, or mitigates a disease unless it has government approval to do so. "Supports immune function" is a structure/function claim. "Treats anxiety" or "helps manage diabetes" is a disease claim, and the March 2025 warning letters to Live Good Inc., Pharmaganics, Lysulin, Nuturna International, Phytage Labs, Ar-Rahmah Pharm, Metamune, Holistic Healer & Wellness Center, Radhanite, and Aceva were all triggered by exactly that line getting crossed on diabetes claims.
Practical rule for your copywriters: before a headline or ad claim ships, ask whether the underlying evidence is a peer-reviewed RCT or a customer testimonial. If it's the latter, the claim needs to be softened to general wellness language. This isn't just an ad-platform requirement, it's the FTC standard itself, and it applies to your website, your packaging, and your organic content, not just paid media.
How Should You Handle Reviews and Influencer Content Without Creating Legal Risk?
Reviews need to be real, unincentivized, and unedited for sentiment, because fake or incentivized reviews are now an independent FTC violation separate from the health claim they support. The TruHeight case is the clearest example of this: the fake review network was penalized on its own terms, not just as evidence supporting the unsubstantiated height claim. If your brand is running review-generation campaigns that offer discounts for five-star reviews, or if an agency or growth team is writing reviews internally, that is the exact pattern the FTC just fined a company $750,000 over.
The same logic extends to influencers. Under the FTC's Endorsement Guides, an influencer making a health claim needs the same level of substantiation the brand itself would need. If a creator says your product "cured my anxiety" or "fixed my gut," that statement creates the same liability as if your brand had written it in an ad. Brief every influencer and UGC creator on what they can and cannot claim, and keep records of those briefs. It is cheap insurance against a very expensive problem.
Meta vs Google for Supplement Brands: Where Should the Budget Actually Go?
Meta is generally the stronger platform for supplement brands because of its targeting depth and creative flexibility, but it comes with age-gating and language restrictions that Google's search-based model doesn't force you into as directly. Google Ads treats dietary supplements as a restricted, not banned, category. No certification is required for standard over-the-counter supplements, unlike CBD or online pharmacies. But Google has a flat prohibition on implying a supplement prevents, cures, or treats a disease unless government-approved, and it maintains a list of more than 150 specifically banned substances and products, covering things like steroid precursors and certain weight-loss and sexual-enhancement products. If your product or a competitor's private-label version resembles anything on that list, expect account-level scrutiny.
Meta requires ads for dietary, health, weight-loss, or weight-gain products to target users 18 and older, and any before/after or results-based claim must clearly state the time it took to achieve those results. A notable shift happened on Meta's July 22, 2026 policy changelog: multiple industry trade sources describe this as a move from product-based enforcement to claims-based enforcement, meaning before/after imagery is no longer automatically rejected, and plain vitamins, general supplements, and protein products may no longer trigger the blanket 18+ requirement unless the ad itself makes a weight-loss or weight-gain claim. Treat that "why" as directionally true but not confirmed by Meta's own language. What is confirmed directly on Meta's policy pages: words like "cure," "treat," "heal," "fix," "diagnose," and "symptoms" get flagged unless the advertiser is a licensed professional with regulatory approval. LegitScript certification isn't mandatory for general supplements, but without it, your copy is effectively locked into general wellness language rather than clinical-sounding claims.
For budget allocation, use Meta for top-of-funnel discovery and retargeting, where its targeting and creative testing loop earns its keep, and use Google primarily for high-intent branded and category search plus Shopping, where people are already looking for a solution and disease-claim restrictions matter less because you're answering a search, not interrupting a scroll. Worth noting for planning purposes: Triple Whale's 2025 data on tracked Health & Wellness brands showed category ROAS down about 15.6% year over year to 2.12, with CPM inflation the steepest of any tracked category at roughly 24.7%, pushing CPMs to around $19.69. That's platform-reported data from an ad-analytics vendor, not an independent audit, but it's a useful signal that acquisition costs in this category are climbing across the board, which makes retention economics (below) even more important than they used to be.
Why Does Subscription Retention Matter More for Supplement Brands Than Other DTC Categories?
Subscription retention matters more here because supplements are a replenishment product where the habit, not the initial signup, is the hard part, and the data on that first stretch is worse than most marketers assume. Recharge, a subscription-commerce platform, analyzed cohorts across roughly 1,800 supplement brands from July 2025 through June 2026 and found only 86.6% of first-time subscribers make it to a second order, and just 1.4% make it to a twelfth reorder, about a year in. Recharge describes this as the leakiest first reorder of any consumable category it tracks.
That means your highest-leverage marketing spend usually isn't the ad that gets someone to subscribe. It's the email, SMS, and packaging experience that gets them through months two and three, before the habit is formed. Build a dedicated retention sequence for days 1 through 90 that addresses "did it work," reorder timing education, and an easy pause option instead of a hard cancel, since a paused subscriber is far easier to win back than a canceled one.
Should a Supplement Brand Prioritize Amazon or Its Own DTC Site?
DTC should be the priority for margin, but Amazon still matters for discovery and trust signals, so most supplement brands need both rather than choosing one. The math is mechanical: Amazon's referral and fulfillment fee stack runs around 30% against typical supplement cost of goods, which eats materially more margin than an owned site with a healthy subscription base. That's a real structural reason, not just a branding preference, that supplement companies lean harder into DTC and subscription than a comparable apparel or home-goods DTC brand would. Context for the broader opportunity: CRN's long-running annual survey with Ipsos found 74 to 75% of Americans currently take dietary supplements, with median monthly spend at $50, up from $48, and 71% reporting brand loyalty once they find a product that works. That loyalty is exactly what a well-run DTC subscription is built to capture, and Amazon is comparatively bad at reinforcing.
Getting the Marketing and Compliance Pieces Working Together
Supplement marketing in 2026 rewards brands that treat substantiation and retention as marketing strategy, not just legal checkboxes bolted on afterward. The category is growing (Grand View Research estimates the global market at roughly $209.5 billion in 2025, on a trajectory toward the low $400 billions by 2033, with the U.S. market around $68.7 billion, though these are modeled projections and different research firms land on different numbers). Growth is there. The brands that capture it will be the ones whose claims can survive scrutiny and whose retention flows are built for the specific first-90-day gap this category has.
This is the kind of work we do for DTC brands at PELORA Marketing, building the paid media, retention, and creative strategy together instead of treating compliance as an afterthought to growth.

Can I say my supplement "boosts immune health" in an ad?
Yes, that is a structure/function claim describing how an ingredient supports the body, which is allowed. What you cannot do is imply the product treats, cures, or prevents a specific disease, since that crosses into a claim requiring government approval and the level of scientific evidence the FTC expects, generally a randomized controlled human trial.
Does Meta require all supplement ads to target users 18 and older?
Under Meta's policy, dietary, health, and weight-management product ads must target 18+, and results-based claims must state the time taken to achieve them. Trade sources describe a July 2026 Meta policy update moving toward claims-based rather than product-based enforcement, meaning plain vitamins and general supplements without weight-loss or weight-gain claims may not trigger the blanket age requirement, though this mechanism is confirmed by secondary sources rather than Meta's own explanation.
Are incentivized reviews illegal for supplement brands?
The FTC's TruHeight settlement shows fake and incentivized reviews are treated as their own violation, separate from any underlying health claim. Offering discounts for positive reviews, editing review sentiment, or having employees write reviews creates direct legal exposure, on top of any risk from the product claims those reviews are meant to support.
Why do so many supplement subscribers cancel after their first order?
Subscription data from Recharge, covering roughly 1,800 supplement brands, found only 86.6% of first-time subscribers reach a second order, since supplements typically take weeks to show noticeable effects and customers cancel before the habit or the results have had time to form. The fix is a dedicated retention sequence in the first 90 days rather than relying on the initial subscription signup alone.
