Immunity Clinical Trial
Official title:
Effect of Protocatechuic Acid on Biochemical Markers of Immunity Status in Healthy Adults
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.
In this pilot study, the Investigator will utilize a double-blind placebo-controlled randomized design. Fifty (50) healthy men and women will be randomized into one of two arms: either agreeing to take placebo or 1000 mg PCA oral capsules daily. Study treatment will continue for 2 weeks (14 days). At baseline and end of 2 weeks treatment period, various clinical and laboratory measurements will be performed. Vital signs, a 2-chair test, and personal health assessment will be measured, and blood will be drawn. The following endpoints will be evaluated in blood: erythrocyte sedimentation rate (ESR), high sensitivity C-reactive protein (hsCRP), C-X-C motif chemokine ligand 9 (CXCL9), 25-hydroxy vitamin D. ;
