Phosphatidylcholine
From the Wikipedia treatment section of vitamin a hypervitaminosis:
- Phosphatidylcholine (in the form of PPC or DLPC), the substrate for Lecithin retinol acyltransferase, which converts retinol into Retinyl esters (the storage forms of vitamin A).
Any thoughts?
That might explain why I seem to benefit from eating sunflower seeds and also why a Nutella spread made with sunflower oil instead of palm oil seems to support my body better.
I also remember when reading about the Lutein-free diet, the author stressed the importance of lecithin and other acetylcholine precursors. It recommended the use of soybean oil which contains soy lecithin for cooking.
The ratio of retinyl esters to serum retinol is the best indication (besides biopsy) of toxicity. The higher the ratio of esters to retinol, the more likely it is that toxicity is present. So I think it would depend on how much storage capacity a person had, as to whether it was beneficial or not. I'm not sure it's what i'd choose.

That's an interesting observation. Lecithin is used as an emulsifier... maybe that's part of the benefit too?
I think the vitamin E in the sunflower seeds would also be very helpful.
I love how their last recommendation is liver transplant..thats how serious VA poisoning is.
