Phosphatidylserine Safety, Risks & Dangers

Initially, many phosphatidylserine supplements were bovine based. As a consequence of the 1990's outbreak of BSE (aka Mad Cows Disease), practically all phosphatidylserine supplements are now soy based to eliminate infection transmission.

There have been no reports from over dosage of phosphatidylserine; oral supplements are safe to take. One study looked at the effects of soy based phosphatidylserine supplements on the elderly [4]. The study found that a dosage of 200mg taken 3 times a day was safe.

Phosphatidylserine Reviews & Testimonials

In some circumstances it may be much cheaper to buy phosphatidylserine supplements in powdered form. However, as dosage is usually low, precision digital scales may be required for accurate measurement of phosphatidylserine powder.
