Semaine uses Citruslabs to substantiate their product claims
The Challenge
Semaine’s primary goal was to be taken more seriously by the medical community. Secondary, the brand was also looking into increased website conversions and wholesale listings of their products. They were looking for a clinical trial partner to help them with substantiating product claims for their website and packaging, all while being on a budget. Apart from validated questionnaires, the studies also included a set of blood markers, as well as before and after pictures.
The Solution
Semaine chose Citruslabs for its simplified and budget-friendly approach to clinical trials. Just 6 months after project kick-off, Semaine was able to publish product claims for their PMS pain relief product. The study helped Semaine to be taken more seriously by the medical community and drove business growth through increased website and ad conversions. Additionally, the study helped Semaine to have an easier conversation with wholesalers, and helped the brand to get listed at Target and Anthropology. Semaine also conducted a second study with Citruslabs, for their Daily Supplement, in which Citruslabs also provided before and after photos.

FAQ about biotech trials
What are the different types of studies for dietary supplements?
There are many different study designs available for dietary supplement clinical trials. Typically, brands start with pilot studies, which are single group (one study arm) and don’t involve a placebo or a control group. Larger brands that already did in-house research also opt for a randomized-controlled trial (RCT) as their pilot study. Studies like these involve at least two study groups (one intervention group and one control or placebo group). The gold standard is a double-blinded randomized-controlled clinical trial, which involves three or more arms (intervention, placebo, and control arm) and neither the study participant, nor the study team knows which participant received the placebo and who received the actual supplement. Another possibility is a crossover study, which belongs to the RCT family, but only includes one study group that serve as their own control group. A crossover study gives you the advantages of an RCT, while staying on a budget. Lastly, consumer perception studies are also an option to consider for supplement brands. These students are less scientific than clinical trials, but still a good way to create robust product claims.
Do vitamins go through clinical trials?
Generally, vitamins can be found on the FDA GRAS list, which lists substances and chemicals that are Generally Recognized As Safe (GRAS). Chemicals and substances on this list are considered safe by experts under the conditions of their intended use and typically underwent clinical studies that were looking at primarily safety. Vitamins or multivitamins sold as dietary supplements can typically be found on that list. However, dietary supplements don’t have to go through clinical trials before reaching shelves and being sold to consumers. However, some brands choose to go the extra mile and pursue clinical trials when launching new products. Brands use these studies to create science-backed product claims that drive trust as well as business growth.
