L-alpha Glycerylphosphorylcholine

L-alpha Glycerylphosphorylcholine, also known as Alpha-GPC, is a compound naturally found in the brain and in some foods like eggs and soy. It is typically produced commercially through chemical synthesis or extraction from soy lecithin.

Alpha-GPC is often added to beverages and supplements marketed for cognitive support. Manufacturers use it as a functional ingredient, believing it may support brain health and memory function.

In the United States, Alpha-GPC is generally recognized as safe (GRAS) for use in certain food categories. Regulatory bodies like the European Food Safety Authority (EFSA) have evaluated its safety, but specific intake limits are not always set. Research into its effects is ongoing, with some studies suggesting potential benefits for cognitive function, while others show mixed results.
