Functional Beverage Clinical Trials
Everyone's selling "energy." Who's measuring it?
How does Citruslabs run studies for Functional Beverage? Citruslabs designs and runs IRB-approved clinical studies tailored to Functional Beverage 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 functional beverages — from prebiotic sodas and energy drinks to adaptogenic elixirs and wellness shots.
The functional beverage market doesn't need another SKU. It needs <em>evidence</em>.
Consumers are getting smarter. Retailers are getting pickier. The brands pulling ahead are the ones who can show you the cortisol data. The cognitive performance scores. The energy markers tracked over time, on their actual product. That is the difference between a marketing claim and a fact. Facts get you the shelf space. Facts get you the buyer. Facts build brand equity that does not collapse the moment the next trending ingredient hits TikTok.

Study Types
Consumer Perception Study
The fastest path to retail-ready marketing claims. Consumers drink your beverage and report structured outcomes. Quick, efficient, and often the smartest first move before committing to something bigger.
Single-Arm Clinical Study
Everyone drinks your beverage. We measure changes over time using biomarkers and validated instruments. Strong clinical substance without the full complexity of a placebo arm. The sweet spot for a lot of functional beverage brands.
Randomized Controlled Trial
Placebo or control. The highest level of substantiated evidence available. For the brands that want to walk into a Whole Foods buyer meeting or an investor room with something nobody can argue with.
Frequently Asked Questions
- How much does a functional beverage trial cost?
- Consumer perception studies typically run $35K to $75K. Single-arm studies run $80K to $180K. RCTs start around $150K and scale based on biomarker complexity and sample size. Transparent pricing. No "book a call just to find out if you can afford us" energy.
- Can I study multiple marketing claims in one trial?
- Yes. If your beverage targets energy and focus, we design one study that measures both. More efficient than running separate trials and your budget will thank you.
- How do you handle beverages containing caffeine?
- Caffeine is a known active. Depending on your positioning, we include it in both arms or evaluate a caffeine-free formulation. Design depends on what you want to isolate and what marketing claims you want to own.
- What if results show a trend but not statistical significance?
- We do not dress up data. If results show directional benefit or subgroup effects, we help you frame marketing claims that are accurate and defensible. Honest positioning is better than bold positioning that falls apart when someone reads the study.
- Do you assess taste and palatability?
- Taste is evaluated within consumer perception studies alongside compliance tracking. If palatability is central to your positioning, we build structured evaluation into the protocol. Turns out people drink more of the things that taste good. Wild.
- Can I use data from a powder format if I sell ready-to-drink?
- Formulation matters. If bioavailability and stability are equivalent, data may transfer. Ideally studies are run on the exact format your consumers actually buy. The can is not the same as the sachet.
- How do you manage participants using competing beverages?
- We screen for competitive product use and build in washout periods where needed. In some cases we intentionally recruit category-engaged consumers to reflect real-world use. It depends on your target audience and what you need the data to show.
Testimonials
We needed clinical proof for our prebiotic soda before our Whole Foods pitch. Citruslabs delivered the study and claims in under 4 months. We got the listing.
