A 42-year-old supplement company that once sold exclusively to doctors is now on pace to hit $650 million in annual revenue — and the shift from boomer prevention to Gen Z performance is the engine behind it.
When Thorne launched in 1984, its business model had no room for the average consumer. Products moved through healthcare practitioners, not grocery aisles or Amazon listings. For over three decades, that approach held. Then something changed — not inside the company, but inside an entire generation’s relationship with health.
From Clinic to Consumer: Thorne’s Structural Shift
Thorne is on pace to reach $650 million in annual revenue in 2026, fueled by Gen Z and millennial shoppers who are increasingly focused on improving their health. The 42-year-old brand, which L Catterton took private in 2023, has sustained a compound annual growth rate of over 30% since the acquisition. Between 2022 and 2025, its revenue more than doubled from $229 million to over $500 million. The number of consumers who shop directly with the brand has grown to approximately 7 million, up from around 4 million at the end of 2023, fueling a 63% surge in direct-to-consumer sales.
That kind of revenue trajectory does not happen by accident. It requires a deliberate transition from one business model to another — and Thorne executed it over a decade-long arc. Thorne launched in 1984 and sold its supplements exclusively through healthcare practitioners until 2015. In 2018, it launched its own direct-to-consumer website. Healthcare practitioners still refer customers, and about 20% of the brand’s sales flow from a healthcare provider referral.
The take-private by L Catterton in 2023 accelerated the transition. Private equity ownership gave Thorne the capital structure to invest in brand infrastructure, marketing, and direct-to-consumer logistics at a scale the company could not have reached organically. The results are in the compounding growth figures.
The Generational Shift Reshaping a $125 Billion Market
The broader context for Thorne’s growth is a category undergoing a structural demographic transformation.
The U.S. vitamins, minerals, and supplements market reached $125 billion in 2025 and is projected to grow 11% by 2027, according to data from consulting firm AlixPartners. Once dominated by older consumers focused on preventative health, the category is now increasingly driven by younger shoppers interested in performance, personalization, and daily wellness routines.
That shift is fundamental, not cosmetic. The boomer consumer was buying supplements to manage decline — joint support, calcium for bone density, multivitamins to fill nutritional gaps. The Gen Z and millennial consumer is buying to optimize a baseline they already consider important. Sleep. Energy. Cognitive performance. Anxiety management. The mental model is entirely different, and it changes what products get purchased, how often they are purchased, and how a brand earns trust.
Thorne CEO Paul Watts, who has worked in the supplement market for 25 years, described the shift plainly in an interview with CNBC: “When I started looking and working in this market 25 years ago, this was a boomer-driven market; you basically focused on servicing the boomers, that’s how you won in the market. So the reality is, today’s market is a Gen Z, millennial market.” About 60% of Thorne’s total revenue now comes from shoppers under the age of 40, who are spending approximately 1.5 times more than their parents did on wellness.
Prevention vs. Performance: The Mindset That Changed Everything
The distinction Watts draws between prevention and performance is worth examining, because it explains why legacy supplement brands with strong clinical credibility — like Thorne — are positioned differently than brands built on trend-chasing.
Watts described the core generational insight: “One of the big Gen Z millennial trends is, they don’t think about supplementation as prevention. They think about it as performance. It’s like, ‘I want to sleep better. I want to have more energy. I want to deal with my anxiety. I want to work out better.’ These are the kinds of things that they’re very, very focused on.”
That language of optimization maps directly onto how Gen Z talks about health on social media — the sleep stack, the morning routine, the magnesium-before-bed ritual. Supplements have entered the self-improvement conversation in a way they simply did not occupy when the category was primarily sold through doctor’s offices.
For Thorne, that is a structural advantage. The brand’s 40-year clinical heritage gives it a credibility floor that newer consumer wellness brands cannot replicate quickly. Third-party testing, NSF Certified for Sport designations, and in-house manufacturing from its South Carolina facility are marketing assets in a market where younger consumers, despite their enthusiasm, are increasingly skeptical about what they are actually buying.
The Subscription Model and the Pricing Discipline Behind It
One of Thorne’s more counterintuitive decisions has been maintaining consistent pricing across channels — a discipline that directly addresses a Gen Z behavioral quirk.
Watts acknowledged that Gen Z is broadly resistant to subscriptions because they dislike finding a product cheaper elsewhere after committing to a recurring order. “We are very disciplined about our pricing. We don’t, you know, high, low, promote the brand. It is fairly consistent.” To incentivize subscriptions, Thorne offers free shipping and a 10% discount on each refill order. When shoppers subscribe to three or more products, they can save 20%. Subscriptions can come as often as every two weeks or as far apart as four months.
That flexibility — and the absence of pricing games — builds the kind of trust that converts a one-time buyer into a 7-million-strong direct customer base.
Addressing the Confidence Gap
The most pointed challenge Thorne identified heading into 2026 was not competition or pricing — it was confusion.
In January 2026, Thorne launched its nationwide “Now I Know” campaign, built around what the company calls the “Wellness Confidence Gap.” Internal research found that more than one in two consumers are unsure which wellness products are best for them due to too much conflicting information. Sixty-five percent of consumers told Thorne it is easier to figure out how to file their taxes than to choose a supplement. Chief Growth Officer Mary Beech described the campaign as designed to position Thorne as a trusted category leader — “helping people make more confident, informed decisions through scientific rigor, transparency, and decades of expertise.”
The campaign ran on connected TV across platforms including Prime Video, Hulu, Paramount+, ESPN, and NBA League Pass — a media mix that tracks exactly where the under-40 audience spends its screen time.
What Thorne’s Growth Signals for the Broader Market
The trajectory that Thorne is on — a 30%-plus CAGR, $500 million in revenue and climbing, a billion-dollar brand aspiration — is not a standalone company story. It is a signal about where the U.S. supplement market is heading and which brands are positioned to capture the next wave of that growth.
The brands that will win are the ones with scientific credibility, clean manufacturing, transparent pricing, and the ability to speak the language of performance to a generation that has made wellness a daily practice rather than a response to illness. Thorne has been building those assets for four decades. The timing of the generational shift, it turns out, aligned with exactly the moment the brand was ready to go direct.
