Varied approaches are taken to evaluate new
nutraceuticals, biotechnologies and devices
to establish their potential health benefits
and safety, including their history of use
as well as laboratory studies using cultured
cell or animal models. Studies involving
human subjects (case reports, observational
studies, and actual clinical trials) can
provide information that is relevant to how
target compounds may be utilized.
Researchers conduct systematic reviews of
scientific literature in order to summarize
relevant data, and to be able to design
clinical trials that meet specific criteria.
This meta-analysis includes a statistical
assessment of scientific data combined from
many studies.
