Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this voluntary research study is to determine if a dietary supplement containing a substance called protocatechuic acid (PCA) can change markers in blood related to immunity (a body's natural ability to fight diseases and infections) over a 14-day study period. Blood tests and other assessments will be completed before and after taking either 1,000 milligrams a day of protocatechuic acid (PCA) or a placebo (i.e., a sugar pill) for 14 days.
