Just wanted to add that RP has stated that when you are not eating PUFA and PUFA storage is depleted, there is zero requirement for vitamin E. Vitamin E was only needed to detoxify PUFA. Is this still the correct thinking?
That is my understanding, but he also said it is almost impossible to be completely PUFA free in the modern world so vitamin E is probably indispensable for most people, even if taken only once weekly.
