Phosphatidylcholine, or PC, is an integral component of cell membranes and, as a source of choline, is also a precursor of the neurotransmitter acetylcholine. It also plays a role in liver health. In a multi-center, randomized, double blind, placebo-controlled trial conducted in Germany, investigators reported that PC helped support liver health by promoting healthy enzyme activity. Animal studies also report that soybean PC may promote healthy lipid metabolism at the hepato-billiary level. Additional animal studies indicate that PC promotes healthy liver and pancreatic antioxidant activity. PC has also been studied in the context of cognitive support and moderating stress. A long-term double-blind placebo controlled trial suggested that high dose soy lecithin containing phosphatidylcholine may lessen mild memory loss associated with aging.
