How does Phosphatidylcholine work?

Phosphatidylcholine is a precursor of a brain chemical called acetylcholine. Acetylcholine is important for memory and other bodily functions.

Are there safety concerns?

Phosphatidylcholine appears to be safe when used appropriately for a short amount of time such as a few weeks. The safety of long-term use is not known.

Phosphatidylcholine can sometimes cause excessive sweating, stomach upset, and diarrhea.

Some people get phosphatidylcholine injections. This can cause irritation, swelling, redness, itching, burning, bruising, and pain at the injection site. These side effects usually go away over a period of several days.

Do not take phosphatidylcholine if:
  • You are pregnant or breast-feeding.
