Searching for Phosphatidylserine shows lecithin as a source but as a soy object that's bad I assume (but cheap!)
I remember reading a MILO article not long ago where someone was promoting lecithin as a supplement...
ends with this nice summation:
When applied to fruits that are nearly ripe – going into puberty, so to speak -- LPE promotes ripening. When applied to picked fruit or cut flowers that are already ripe or blooming, however, it will "reduce senescence by inhibiting some of the enzymes involved in membrane breakdown." This can dramatically extend shelf life.38 Whether the substance could also keep human bodies fresh for funeral home viewings has not yet been investigated.
