Clinical proof that sells product
The supplement market is drowning in unsubstantiated claims. We help you become the brand that can actually prove it — with clinical trials designed around what your marketing team needs, not what a scientist publishes.
How does Citruslabs run studies for Supplements? Citruslabs designs and runs IRB-approved clinical studies tailored to Supplements brands — consumer perception studies (4–8 weeks, $15K+), single-arm clinical studies (8–12 weeks, $40K+), or randomized controlled trials (12–16 weeks, $80K+). Each study uses category-appropriate endpoints and biomarkers, ships with a marketing claims appendix reviewed for FTC and FDA best practices, and earns the optional Citruslabs Tested Seal if the data supports product claims.
Clinical trials and consumer studies for vitamins, minerals, adaptogens, and functional supplements.
Your competitors are making claims they can't defend
The FDA and FTC both require that supplement brands substantiate their health claims with scientific evidence. That's not optional — it's the law. But most brands skip this step, relying on ingredient-level research or generic "studies show" language that wouldn't survive a challenge letter. Clinical trials change the math entirely. They give you product-specific evidence — not borrowed science from someone else's ingredient supplier. Your product, tested on real people, with statistically significant results you can put on your packaging, your PDPs, and your retail pitch decks. That's the difference between a claim that sounds good and a claim that holds up under FTC scrutiny, Amazon review flags, or a Whole Foods buyer asking "where's the data?"
"Contains ashwagandha, which has been shown to support stress response"
"In a clinical study, 89% of participants reported reduced stress within 30 days"
Categories
Cognitive & Nootropics
Focus, memory, mental clarity, brain fog reduction. We pair subjective questionnaires with cognitive battery testing for claims that have both the data and the story.
Gut Health & Probiotics
Digestive comfort, bloating reduction, microbiome diversity. We coordinate stool sample collection and pair it with symptom tracking for multi-dimensional proof.
Sleep & Relaxation
Sleep onset, duration, quality, next-day energy. We integrate wearable data from Oura and Fitbit alongside validated sleep questionnaires like the PSQI.
Energy & Performance
Sustained energy, exercise recovery, endurance. Pre- and post- bloodwork for inflammation markers plus validated fatigue scales give you claims with teeth.
Beauty & Hair/Skin/Nails
Skin hydration, hair growth, nail strength, collagen support. Standardized photography, expert grading, and device-measured skin markers give you visual and quantitative proof.
Stress & Adaptogens
Cortisol reduction, stress resilience, mood balance. We can measure cortisol via saliva collection and pair it with validated instruments like the PSS-10.
Study Types
Perception Study
Consumer-reported outcomes via validated questionnaires. Fastest path to "9 out of 10 users agree" claims.
Single-Group Trial
Add bloodwork, biomarkers, or wearable data for quantitative proof. The sweet spot between speed and rigor.
Randomized Controlled Trial
Treatment vs. placebo with random assignment. The most defensible design for high-stakes claims and retail.
Crossover Study
Participants serve as their own control — giving you RCT-level evidence with a smaller (and more affordable) sample size.
Frequently Asked Questions
- How long does a typical supplement study take?
- Most supplement clinical studies run 4–12 weeks, depending on the study design and endpoints. Perception studies can wrap in as little as 4 weeks, while RCTs with biomarkers typically take 8–12 weeks.
- Can you test multiple SKUs in one study?
- Yes. We can design multi-arm studies or sequential protocols that test multiple products, dosages, or formulations. This is common for brands with a lineup they want to substantiate efficiently.
- What biomarkers can you measure?
- We measure 50+ biomarkers including full blood panels, hormonal markers, microbiome composition, inflammatory markers, and more. We also integrate wearable data and continuous glucose monitoring.
- Do you handle IRB approval?
- Yes, we manage the entire IRB submission and approval process. Every study we run goes through a full Institutional Review Board review before enrollment begins.
- What's the difference between a perception study and a clinical trial?
- A perception study captures consumer-reported outcomes — how people feel after using your product. A clinical trial adds objective measurements like blood panels, biomarkers, or device data to validate those claims quantitatively.
- Will my claims hold up with retailers like Whole Foods or Target?
- That's what we design for. Every claim we deliver includes the underlying data, statistical analysis, and a formatted study report that retail buyers expect during product review.
Testimonials
Citruslabs gave us the data we needed to go from 'may support' to '92% of users reported improvement.' That single claim change increased our conversion rate by 34%.
Sarah Chen, VP Marketing at NutriVive
We were skeptical about the timeline, but they delivered our complete study report — with marketing-ready claims — in just 8 weeks. Our Whole Foods buyer was impressed.
Michael Torres, Founder & CEO at Adaptogen Labs
The biomarker data was the game-changer. Having actual blood panel results backing our claims made our Amazon listing untouchable during compliance reviews.
