Phosphatidyl Serine Powder And Liquid 20%, 50% 70%
Phosphatidylserine is a chemical. The body can make phosphatidylserine, but gets most of what it needs from foods. Phosphatidylserine supplements were once made from cow brains, but now are commonly manufactured from cabbage or soy. The switch was triggered by a concern that products made from animal sources might cause infections such as mad cow disease.
