Studies for nutritional supplements

These are Leon Research’s services

In studies with food supplements, it is very important to have a partner who can advise and support you throughout the study: from the design of the study and the strategy to follow-up the analysis of the data and the final report.

After a meeting, our business development team prepares a detailed budget with all the tasks we think are necessary, as well as an estimated Gantt chart to know how long it will take.

We must keep in mind that the adherence of the participants in the nutritional supplement study is much lower than in a clinical trial and that the sites are not hospitals, so they are not as familiar with the clinical process.

We believe that the sites selection and the monitoring are two key elements for the quality and relevance of the data collected.

Studies for cosmetic products

These are Leon Researchs’ services

At León Research we offer solutions that include all the activities from the design and start-up of a study with a cosmetic product to data management and the final report or article.

To work together, we start with a meeting, after which we can prepare a budget with all the services detailed and with estimated timelines that include the time necessary for approval, recruitment, monitoring and data management.

In this type of cosmetic study, it is essential to select the right sites and their correct monitoring to ensure that the data is well collected, since the participants are usually less compromised than in a clinical trial.

We also offer Cosmetovigilance, essential to be able to follow-up after authorization.
