Democratizing Natural Supplement Research
Join a professionally conducted observational study exploring the use of RTN dietary supplements. This is not a traditional clinical trial but a structured way to gather real-world data on Retisin, Lyastin, Floristen, and Silexil.
How the Study Works
Your role and participation
Participants voluntarily take selected RTN supplements, regularly consult with their doctor or our nutrition specialist, and share information about their health, lifestyle, and subjective experiences, such as energy levels, sleep patterns, and physical activity.
Data Analysis
Turning information into insight
All shared data is anonymized and analyzed to better understand the potential long-term effects of RTN supplements on health, longevity, and chronic inflammatory conditions. This data also supports the digital RTN GPT Assistant platform.
