In a comment that soy lecithin may be bad for you I found the following: However, some of the few soy lecithin studies have shown that choline might help treat dementia. Other experiments showed a slight cholesterol decrease in humans and animals taking soy lecithin or choline supplements. Still, moderation is key—people who chronically take more than 3.5 grams of choline per day occasionally have experienced side effects, including low blood pressure, marked by fainting or dizziness.
