pslam,
I've taken lecithin off and on for 30 years. I started when I read Adele Davis who swore by it as a way of keeping fat from accumulating in livers, especially in heavy drinkers (which i was.)
Claims for the benefits of phospholipids are EVERYWHERE on the net.
I've been religious about a Tbsp a day (granular) for 4 years now (with my cod liver oil.) It's cheap and delicious (Puritan Pride is the cheapest souce I've found.) The only slightly annoying aspect is it's tendency to paste to the teeth.

Take BEFORE brushing! I used to buy it as a liquid in a can but I don't think it's around that way anymore. Horse capsules are available but expensive to take that way.
It is a potent fat emulsifier and it seems to be implicated in HDL synthesis (hazy here.)
I have GREAT faith in it (and I'm not much one for faith!

)
