Function&Application
1 A standard dose of phosphatidylserine (PS) is 100mg, taken 3 times a day to total 300mg daily. This dose seems to be effective as a daily preventative against cognitive decline, and 100mg once daily may provide some degree of benefit (but may be lesser than 300mg).
2 Studies in children and adolescents for the purpose of attention improvement tend to use 200mg, and a dose of 200-400mg has been used in adult non-elderly humans with success. Animal evidence tends to use a dose correlating to 550mg as well.
