Carnitine Metabolism Gut Flora Phosphatidylcholine

ClinConnect Summary

The principal goal for the study is to examine the role gut flora plays in modulating metabolism of dietary trimethylamine nutrients in humans. We have recently shown that dietary intake of two trimethylamines abundant in animal products, carnitine and the choline group of phosphatidylcholine (PC), are mechanistically linked to cardiovascular disease risk. We wish to further explore the metabolism of these nutrients in humans, and to test the hypothesis that the intestinal micro flora (gut flora) plays a critical role in generation of metabolites from dietary carnitine and choline/PC linked...
