Phosphatidylcholine makes up a large portion of lecithin and is a source of choline, an essential nutrient. Your body uses this choline to construct cell membranes and produce acetylcholine, a neurotransmitter tied to memory and focus.
Many people take phosphatidylcholine to bolster cognitive function and brain health. It also assists fat metabolism by helping transport fats out of the liver, which supports liver function.
Phosphatidylcholine comes in softgels or powder and is best taken with meals. The right dose depends on the person and the specific product. Some take it mainly as a choline supplement to help with focus.
Phosphatidylcholine rarely causes side effects. High doses can bring mild stomach discomfort. Check the source if you are allergic to soy or eggs. Talk to a healthcare provider before using if you are pregnant or nursing.
