Data-backed product claims.
Ready for marketing.

A clinical trial is a structured, scientific study designed to measure objective outcomes, like changes in bloodwork, microbiome composition, or data from wearable devices such as CGMs, sleep trackers, or blood pressure monitors. Clinical trials often include validated questionnaires to assess specific health outcomes, such as cognitive performance, sleep quality, digestion, or mood, using standardized, peer-reviewed tools. These studies are typically used to support health claims or structure/function claims, and follow strict protocols, usually with IRB approval, lab testing, and longer timelines. A consumer perception study is faster, more flexible, budget-friendly, and focused on how customers experience your product in their daily lives. Instead of objective metrics or lab data, participants report on how the product looks, feels, or performs, allowing you to generate credible, data-backed marketing claims based on real-world feedback. Both approaches involve real people. The difference lies in what you’re measuring and how you’re using the results.

Most brands see results within 2–14 weeks, depending on product type and how quickly you recruit customers.

You can make marketing claims based on how real customers experience your product, for example (the following is not an exhaustive list): • “Visible results in 7 days” • “93% would buy again” • “89% said their skin felt smoother and more hydrated” • “81% noticed improved energy throughout the day” • “76% fell asleep faster and stayed asleep longer” • “85% said their gut felt more balanced” • “90% reported reduced bloating after two weeks” • “94% would recommend to a friend” • “Skin looked more radiant in just one week” • “Stronger nails and healthier-looking hair after consistent use” • “8 out of 10 said the product became a staple in their routine” • “Improved focus and mental clarity during the workday” We analyze your data and deliver claims you can confidently use across PDPs, ads, packaging, and retail decks, all based on real-world feedback, not just assumptions. Disclaimer: The example claims listed above are for illustrative purposes only and do not constitute legal advice. All claims used in your marketing materials should be reviewed for compliance with relevant regulatory and advertising standards. Citruslabs provides data to support product claims, but final responsibility for claim usage rests with the brand.

You invite your own customers, typically post-purchase buyers, at checkout, via email, SMS, or a custom link. This ensures feedback comes from real users of your product.
