Lecithin is an ingredient in Metabolife that, alone, has been reputed for its beneficial effects upon plasma cholesterol (LeBlanc et al., 1998). Other benefits of a lecithin-enriched diet include prevention of "intrahepatic chlestasis induced by cholic acid infusion" and it's ability to extensively metabolize into lysolecithin, fatty acids and choline" (LeBlanc et al., 1998). LeBlanc and associates concluded in their study that choline, a component of lecithin, is responsible for the beneficial attributes of lecithin itself (1998). Lecithin has also been shown to enhance the flow of bile, as well as bile acid transport. The final conclusion of the study was that "diets enriched in lecithin or choline exert a beneficial effect against bile acid-induced cholestasis" (LeBlanc et al.,1998). Thus, given the data of this study, lecithin can assumedly be considered a "safe" ingredient in Metabolife. Moreover, the connection between lecithin and cholesterol and such offers an explanation as o where the lecithin fits within the weight-loss supplement. However, the study did not look for, nor mention any negative side effects of the lecithin. Without this information, lecithin cannot truly be considered a safe product. As is, it would be more accurate to consider it to be low risk.
