Functional Food Clinical Trials
Your granola bar says it supports gut health. Based on what?
How does Citruslabs run studies for Functional Food? Citruslabs designs and runs IRB-approved clinical studies tailored to Functional Food 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 foods — from protein bars and superfood powders to gut-health snacks and meal replacements.
Fast growth. Higher expectations.
Food is so 2020. It is functional food now. Every snack brand, cereal company, and cookie manufacturer is slapping "supports immunity" or "supports digestive health" on their packaging and hoping nobody asks too many questions. Spoiler: people are starting to ask. Whole Foods asks. Sprouts asks. Regulators are warming up. Investors definitely ask. Most of your competitors have nothing behind their marketing claims but good copywriting and a mood board. Be the brand that actually has clinical evidence. That is not just a marketing advantage. That is a moat.

Study Types
Consumer Perception Study
The fastest path to retail-ready marketing claims. Participants use your product and report structured outcomes. Quick, efficient, and often the smartest first move before committing to something bigger.
Single-Arm Clinical Study
Everyone gets your product. 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 food 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 food trial cost?
- Consumer perception studies typically start at $20K to $40K. Single-arm studies start at $50K to $100K. RCTs start at $100K to $250K+ and scale with complexity. Final scope depends on biomarkers, sample size, and timeline. No hidden fees. No surprise add-ons. Just a transparent quote built around what your product actually needs.
- Can I use my study to make disease marketing claims?
- No. Functional food marketing claims live in structure and function territory. Disease claims require FDA pre-approval and a completely different regulatory pathway. We help you find the strongest defensible marketing claim within your category. The one that is both bold and compliant.
- What if I already have ingredient research?
- Ingredient studies give you background. Your formulation, dose, and matrix are what actually matter on shelf. We design studies on your finished product so the marketing claims belong to your brand and nobody else can borrow them.
- Can you study multi-ingredient functional foods?
- Yes. Most functional foods combine multiple ingredients. We design studies around the full formulation, measuring outcomes that reflect the product exactly as consumed. No cherry-picking single actives.
- How do you account for dietary variability?
- We control baseline intake, track diet during the study, and select biomarkers that minimize background noise. For tighter control, randomized designs are often the right call.
- Can you support plant-based or allergen-related positioning?
- Yes. We verify ingredient composition and design studies for specific populations when tolerance or sensitivity marketing claims are central to your positioning.
- Do you work with both large CPG and emerging DTC brands?
- Yes. Legacy CPG and early-stage DTC. Study scale varies. The objective does not. Generate clinical evidence aligned with your commercial goals and put it to work everywhere it needs to show up.
