Red wine and grape polyphenols are considered to promote cardiovascular health and are involved in multiple biological functions. Their overall impact on the human metabolome is not known. Therefore, exogenous and endogenous metabolilc effects were determined in fasting plasma and 24-hour urine from healthy male adults consuming a mix of red wine and grape juice extracts (WGM) for four days in a placebo-controlled, cross-over study. Syringic acid, 3-hydroxyhippuric acid, pyrogallol, 3-hydroxyphenylacetic acid, and 3-hdyroxyphenylpropionic acid were confirmed as strongest urinary markers of WGM intake. Overall, WGM had a mild impact on the endogenous metabolism. Most noticeable were changes in several amino acids deriving from tyrosine and tryptophan. Reductions in the microbial metabolites p-cresol-sulfate and 3-indoxylsulfuric acid and increases in indole-3-lactic acid and nicotinic acid were observed in urine. In plasma, tyrosine was reduced. Our results suggest that short-term intake of WGM altered microbial protein fermentation and/or amino acid metabolism.
