Does soy lecithin contain isoflavones

Soy lecithin typically does not contain significant amounts of isoflavones. Lecithin is primarily a fat extracted from soybeans, and the process of extracting lecithin usually removes most of the isoflavones, which are a type of phytoestrogen found in whole soy products. Therefore, while soy lecithin is derived from soy, it is not a notable source of isoflavones.
