Dietary supplement containing phospholipid-DHA derived from eggs
Described herein are manufactured dietary supplements that contain a phospholipid extract and the extract contains two forms of phospholipid-docosahexanoic acid. One form of phospholipid-docosahexanoic acid is phosphatidylcholine-docosahexanoic acid, and another form of phospholipid-docosahexanoic acid is phosphatidylethanolamine-docosahexanoic acid.
