If I take phosphatidylserine supplements, how much should I take?

Adults (18 years and older):

• Although phosphatidylserine derived from bovine cortex (BC-PS) has been used in studies, it is currently not administered to humans because of possible transfer of infectious diseases, including bovine spongiform encephalopathy (commonly known as mad cow disease). Soybean phosphatidylserine (PS) is currently used instead of BC-PS.

• For age-related memory disorders, 100 milligrams of BC-PS has been taken by mouth three times daily for three months, and 200 milligrams of phosphatidylserine has been taken by mouth twice daily for six months.

• For stress, 200 milligrams of soy-based phosphatidylserine has been taken by mouth daily for 42 days, and also, 600 milligrams of soy-derived phosphatidylserine has been taken by mouth daily for 10 days.
