I am looking for a bovine source of Phosphatidylserine anyone can point me in the right direction? I have been researching phosphatidylserine for it’s cortisol lowering effects.
There are two supplement sources of PS one from bovine and the other from soy/lecithin. The bovine source is the one that has the positive results (from what I have read so far) in relation to cortisol. Thanks in advance. Love this site great resources.
