Clinical trials are vital to the success of branded nutraceutical ingredients and supplements, demonstrating their efficacy in a wide range of population groups. However, traditional trials can be costly in time and resources, often requiring participants to travel to a research center multiple times to take a supplement or ingredient and test its impact. US-based People Science offers an alternative. The clinical research company addresses a need for affordable, rigorous clinical science through its mobile app, Chloe, which allows people to join a clinical trial from home.
