Question: Are the PUFAs in phosphatidylcholine supplements a concern?I don't think so. I think that you're looking at fairly low levels of PUFAs in there, but the way that I see it is yes, we want to restrict PUFA beyond what's needed, but what's needed is defined by what do we need to get our essential nutrients in.
