Phosphatidylserine

How does Phosphatidylserine work?

Phosphatidylserine is an important chemical with widespread functions in the body. It is part of the cell structure and is key in the maintenance of cellular function, especially in the brain.

Are there safety concerns?

Phosphatidylserine might be safe for most people. Phosphatidylserine can cause insomnia and stomach upset, particularly at doses over 300 mg.

There is some concern that products derived from animal sources could transmit diseases, such as mad cow disease. To date, there aren't any known cases of humans getting animal diseases from supplements, but look for supplements made from plants to be on the safe side.

Do not take phosphatidylserine if:
  • You are pregnant or breast-feeding.
