Alpha-GPC
Alpha-GPC (alpha-glycerophosphocholine) is a highly bioavailable choline compound that occurs naturally in the brain and is also found in small amounts in foods like eggs and organ meats. It rapidly converts to phosphatidylcholine after ingestion, making it one of the most efficient ways to deliver choline to the central nervous system. It is widely used for cognitive support and as a sports performance aid.
