choline is also very high in organic free-range eggs (where the hens are in grass and can hunt)
And a herb al tea also exceptionally high in choline is chickory root (a flower-root, tea is bitter, but really makes one feel good!)
Lecthin granules can be a good source of choline, but you need to have a strong production of stomach acid to be able to win the phosphatidylcholine out of it!
