Answer Capsule

Thorne is the dominant recommendation leader in the Sleep and Stress Supplements category, holding 91.21% valid recommendation coverage in September 2026 across 535 qualified AI observations. The brand appears in 96.64% of all qualified responses and is recommended in the top three positions 83.93% of the time, with a rank-one rate of 49.53%. Its clearest strength is near-universal presence combined with the highest top-three placement rate in the category. Its clearest weakness is a notable decline in rank-one recommendations, which fell 11.3 points from 60.8% in August 2026. The clearest opportunity is defending first-choice positioning in high-intent prompts where competitors are beginning to capture the top recommendation slot.

Executive Summary

Thorne holds the strongest recommendation position in the Sleep and Stress Supplements category. The September 2026 benchmark shows Thorne with 91.21% valid recommendation coverage, meaning the brand receives a clear recommendation in more than nine out of ten qualified AI responses. This places Thorne 9.0 percentage points ahead of Nature Made, the second-ranked brand at 82.2% coverage.

Thorne's raw mention presence rate is 96.64%, essentially universal across the qualified benchmark set. The brand was mentioned in 517 of 535 qualified observations and received valid recommendation credit in 488 of those. Positive mentions totaled 510, with 7 neutral mentions and zero negative mentions, producing a net sentiment score of 0.9865.

The strongest cluster for Thorne is Best Vitamins and Dietary Supplements, the only buyer-intent cluster with qualified observations in the current benchmark. All 535 qualified observations fell into this recommendation-driven cluster. Thorne's top-three recommendation rate in this cluster is 83.93%, and its rank-one rate is 49.53%.

The clearest weakness is a decline in rank-one recommendations. Thorne's rank-one rate fell from 60.8% in August 2026 to 49.53% in September 2026, an 11.3-point drop. While overall coverage remained stable within normal variation, the brand is being named as the single first-choice option less often than in the prior month.

Platform-level performance shows Thorne leading across all six tracked AI surfaces. The strongest platform signal is Perplexity, where Thorne achieved a 95.9% valid recommendation coverage rate and a 56.2% rank-one rate. ChatGPT also shows strong performance with a 91.7% coverage rate and an 83.3% rank-one rate. The weakest platform signal is Copilot, where Thorne's rank-one rate is 40.3%, lower than its category average.

The clearest platform gap is the decline in rank-one positioning across multiple surfaces. While Thorne remains the most recommended brand overall, competitors are beginning to capture first-choice moments in prompts where Thorne previously led. This pattern warrants focused investigation into which prompt types and evidence sources are driving the shift.

What Thorne Is Winning

Questions This Section Answers

  • How far ahead of Nature Made and Pure Encapsulations is Thorne on valid recommendation coverage?
  • Which platforms show Thorne's strongest coverage and rank-one performance?
  • What does Thorne's zero negative mentions and 0.9865 net sentiment reflect about its recommendation positioning?

Thorne holds the highest valid recommendation coverage in the category at 91.21%, ahead of Nature Made at 82.2% and Pure Encapsulations at 74.0%. The brand is recommended in the top three positions 83.93% of the time, more than 23 percentage points ahead of the next closest competitor.

Thorne's rank-one rate of 49.53% is more than three times higher than Nature Made's 15.7% and nearly six times higher than Pure Encapsulations' 8.4%. When AI systems recommend a sleep or stress supplement brand first, Thorne is the answer nearly half the time.

The brand shows zero negative mentions across all 535 qualified observations. Net sentiment stands at 0.9865, reflecting overwhelmingly positive framing when Thorne appears in AI responses.

Thorne leads on every tracked platform. On Perplexity, the brand achieves 95.9% coverage and a 56.2% rank-one rate. On ChatGPT, coverage reaches 91.7% with an 83.3% rank-one rate. On AI Mode, coverage is 90.8% with a 43.3% rank-one rate. On AI Overviews, coverage is 89.6% with a 42.2% rank-one rate. On Copilot, coverage is 86.1% with a 40.3% rank-one rate. On Gemini, coverage is 95.5% with a 56.1% rank-one rate.

Where Thorne Has the Clearest AI Visibility Gaps

Questions This Section Answers

  • Why is Thorne's 11.3-point rank-one decline significant even though overall coverage stayed stable?
  • On which platforms is Thorne most vulnerable to losing first-choice positioning?
  • Which competitors are gaining rank-one ground in the Sleep and Stress Supplements category?

Thorne's primary gap is not presence but first-choice positioning. The brand's rank-one rate declined 11.3 points from August 2026 to September 2026, even as overall coverage remained stable. This suggests that while Thorne remains the most recommended brand, competitors are increasingly capturing the single top recommendation slot in certain prompts.

The gap is most visible on Copilot, where Thorne's rank-one rate is 40.3%, compared to 83.3% on ChatGPT and 56.2% on Perplexity. Copilot represents the platform where Thorne is most vulnerable to losing first-choice positioning.

On AI Mode, Thorne's rank-one rate is 43.3%, and on AI Overviews it is 42.2%. These rates are strong in absolute terms but represent a meaningful gap compared to the brand's performance on ChatGPT and Perplexity.

The competitive landscape shows Nature Made as the strongest challenger, with 82.2% coverage and a 15.7% rank-one rate. While Nature Made's rank-one rate is significantly lower than Thorne's, the brand's 60.19% top-three rate indicates it frequently appears alongside Thorne in recommendation lists. Pure Encapsulations, despite a 7.4-point coverage decline in September 2026, maintains a 55.33% top-three rate and an 8.41% rank-one rate.

Ritual showed a notable rank-one gain in September 2026, rising 4.2 points to 9.35%. While still far below Thorne's rank-one rate, the increase suggests Ritual is converting a higher share of its mentions into first-choice placements.

Biggest Opportunity

Thorne's biggest opportunity is defending and recovering rank-one positioning in high-intent recommendation prompts. The brand already dominates overall coverage and top-three placement. The path from reference to recommendation is complete. The remaining opportunity is ensuring Thorne remains the first brand named when AI systems answer questions like "What is the best supplement company to buy from?" or "Which melatonin is best for sleep?"

This requires understanding which prompts and platforms saw rank-one declines in September 2026, which competitors captured those first-choice moments, and what evidence sources or answer formats drove the shift. The brand's near-universal presence means the foundation is strong. The work is in reinforcing the signals that position Thorne as the single best answer, not just one of several recommended options.

Competitive Landscape

Questions This Section Answers

  • How large is Thorne's lead over Nature Made and Pure Encapsulations on top-three and rank-one rates?
  • Where do Ritual, Nordic Naturals, and the remaining tracked brands stand in the recommendation hierarchy?
  • What do the average recommended rank and sentiment columns reveal about the gap between Thorne and the rest of the field?

Thorne holds dominant recommendation power in the Sleep and Stress Supplements category, with Nature Made as the strongest challenger and Pure Encapsulations as the third-ranked brand. Ritual leads the middle tier, while the remaining tracked brands show limited recommendation-stage visibility.

Average recommended rank covers rank-eligible recommendations only.

Thorne's position at the top of the table reflects its dominant recommendation power. The brand's 83.93% top-three rate is more than 23 percentage points ahead of Nature Made, and its 49.53% rank-one rate is more than three times higher than any competitor. The gap between Thorne and the rest of the field is substantial across every placement metric.

Prompt Evidence

ChatGPT / Best Vitamins and Dietary Supplements Prompt: "What is the top rated women's multivitamin?" Result: Thorne was recommended as the first option, with strong positive framing and a rank-one placement.

Perplexity / Best Vitamins and Dietary Supplements Prompt: "What is the best supplement company to buy from?" Result: Thorne appeared as the top recommendation, with the brand cited alongside quality and trust signals.

AI Mode / Best Vitamins and Dietary Supplements Prompt: "Which melatonin is best for sleep?" Result: Thorne was recommended in the top three, though not as the first option in this instance.

Copilot / Best Vitamins and Dietary Supplements Prompt: "Best multivitamin for women" Result: Thorne appeared in the recommendation list but ranked lower than on other platforms, reflecting the brand's weaker rank-one performance on Copilot.

What CiteWorks Studio Would Do Next

Phase 1: AI Market Discovery Audit Map Thorne's recommendation footprint across all six tracked platforms, identifying which prompt types and clusters show rank-one declines and which competitors are capturing first-choice moments.

Phase 2: Recommendation Readiness Plan Prioritize the prompts and platforms where Thorne's rank-one rate has declined, focusing on Copilot and AI Mode where the gap to the brand's ChatGPT and Perplexity performance is largest.

Phase 3: Owned Answer Layer Buildout Strengthen the owned content and structured data that AI systems retrieve when forming recommendations, ensuring Thorne's first-choice positioning is reinforced across high-intent prompt types.

Phase 4: Citation / Authority Layer Development Expand the public evidence layer that supports Thorne's recommendation strength, including third-party reviews, expert citations, and comparison content that AI systems may synthesize when forming answers.

Phase 5: Monthly AI Visibility and Recommendation Tracking Monitor Thorne's rank-one rate, top-three rate, and coverage across all platforms to detect shifts in first-choice positioning and respond to competitor gains in real time.

Why This Matters

AI presence alone is not enough. Thorne already appears in nearly every qualified AI response in the Sleep and Stress Supplements category. The brand's challenge is not visibility but recommendation conversion at the highest level. Being named as one of several recommended options is valuable. Being named as the single best option is more valuable.

The September 2026 benchmark shows Thorne losing ground on rank-one recommendations even as overall coverage remains stable. This pattern suggests that competitors are finding ways to position themselves as the first-choice answer in certain prompts. The next move is targeted correction of the prompt, page, and citation layers that drive first-choice positioning. Thorne's dominance is not in question. The work is in defending the top spot.

Sentiment Score

Sentiment Score = (positive mentions × 1 + neutral mentions × 0 + negative mentions × -1) / total mentions

Thorne's sentiment score for September 2026 is 0.9865. This is calculated from 510 positive mentions, 7 neutral mentions, and 0 negative mentions across 517 total mentions.

This score matters because unclassified mention counts are misleading. A brand can appear frequently in AI responses without being recommended, and a neutral reference is not the same as a positive recommendation. Counting all mentions as wins is bad measurement. Classified sentiment is required before interpreting AI visibility.

Thorne's near-perfect sentiment score reflects overwhelmingly positive framing when the brand appears in AI responses. The 7 neutral mentions represent instances where Thorne was referenced without clear positive or negative framing. The absence of negative mentions indicates that AI systems are not surfacing cautionary or critical content about the brand.

Methodology

  1. This report is a benchmark-based analysis of Thorne's AI recommendation performance in the Sleep and Stress Supplements category. It is not a client implementation case study.
  2. The reporting window is September 2026, with comparison to August 2026 baseline data where available.
  3. Six AI platforms were tracked: ChatGPT, Copilot, Gemini, Perplexity, AI Overviews, and AI Mode.
  4. The September 2026 benchmark analyzed 535 qualified observations from an initial collection of 800 prompt-surface observations.
  5. The competitor universe includes 10 tracked brands: Thorne, Nature Made, Pure Encapsulations, Ritual, Nordic Naturals, Olly, HUM Nutrition, Momentous, Gaia Herbs, and Moon Juice.
  6. All 535 qualified observations fell into the Brand Recommendation buyer-intent cluster. No qualified observations fell into Pricing and Value or Multi-Brand Comparison clusters in the current benchmark.
  7. Stage 0 extraction identified brand mentions, recommendation placements, sentiment, and cited evidence sources where exposed.
  8. A mention is defined as any instance where Thorne appears in an AI response, regardless of whether the brand is recommended.
  9. A valid recommendation is defined as an instance where Thorne receives a clear recommendation with a rank position of 1 through 10.
  10. Brand-level percentages use the 535 qualified observations as the public denominator, not the raw collection of 800 prompts.
  11. Unique question count for September 2026 was 577. The public benchmark does not expose the full prompt list.
  12. Movement between months identifies changes worth investigating. It does not by itself establish the cause of those changes.

Understanding AI search visibility.

AI search experiences create answers by pulling information from many places online and summarizing it into a single response.

What Is AI Citation Intelligence?
AI citation intelligence is the process of measuring where AI platforms source their information and how frequently a brand is mentioned or referenced in AI-generated responses. Because LLMs synthesize across multiple sources, the sites and brands that appear repeatedly tend to influence how a topic or company is framed. This practice focuses on identifying which sources shape AI outputs and tracking brand visibility across different AI systems.
What Is Citation Architecture?
Citation architecture describes the set of sources that consistently inform how AI systems talk about a brand, product, or topic. LLMs draw from websites, articles, forums, and public discussion, and the sources they rely on most often become the backbone of their answers. Building strong citation architecture means ensuring that accurate, credible, high authority sources are the ones most likely to shape the way AI tools summarize and recommend a brand.
What Is Generative Engine Optimization?
Generative engine optimization (GEO) is the practice of improving the chances that AI systems use and cite your brand or content when generating answers. While traditional SEO is centered on ranking pages in search results, GEO focuses on how LLMs retrieve, interpret, and combine information when responding to a question. The objective is to strengthen the content and sources AI systems rely on, so your brand is treated as a trusted reference in AI responses.
What Is AI Share of Voice?
AI share of voice tracks how often a brand appears in AI-generated answers compared with competitors in the same category. It reflects visibility across AI platforms such as ChatGPT, Gemini, Claude, and Perplexity. Monitoring AI share of voice helps organizations see whether AI systems consistently include and recommend their brand for key queries or whether competitor brands are showing up more often.
