Phosphatidylserine is taken to try to prevent memory loss and mental decline that may occur as you get older.

Phosphatidylserine is a phospholipid that protects the cells in your brain. This fatty substance transmits messages in your brain to help your memory and cognitive function. Phosphatidylserine is available as a supplement. It isn't U.S. FDA-approved to treat any medical conditions, but is generally recognized as safe.

CAUTION: Phosphatidylserine supplements may pose potential risks for pregnant or breastfeeding women, individuals with blood clotting disorders or those taking certain medications, and may cause allergic reactions or mild digestive upset in some individuals.

DIRECTIONS FOR USE: For cognitive support, a typical phosphatidylserine dosage ranges from 100 mg to 300 mg per day, with some studies indicating increased efficacy when divided into two daily doses.
