I'll review this, always glad to see a Vital Article come through here. Immediately, I am worried about the handful of citation needed tags and the glaring number of sentences that are missing sources. I will keep the review open for now (until 12/15), since I am familiar with the general quality of your work, but I won't go much further until these issues are resolved. Once this is resolved, we can discuss a time frame for the rest of the page. I understand these topic can take time, vital articles tend to be a long haul. Thankfully, my degree is related close enough to this topic (Human Biology) for me to give a relatively technical review of the article.

Technically, there is nothing inherently wrong with this copyright. That being said, a structural formula copyright (see File:Alpha-Tocopherol Structural Formulae V.1.svg) is more accurate. No other issues noted with the copyrights.
Earwig only flags 3-4 word proper nouns and phrases that really can't be reworded.
The missing citation issue has been raised above.
Intro
Vitamin E deficiency, which is rare and usually...move to the end of the paragraph
Both natural and synthetic tocopherols...Move to end of paragraph
Chemistry
The nutritional content...move to later in the paragraph, it doesn't make sense to introduce a RRR configuration before explaining methyl groups, adding to the end would work.
R" sitesYou and I know what this means but specify this is a functional group. I can potentially read like its a chiral center
Palm oil is a good source of alpha and gamma tocotrienolsout of place sentence
two corresponding centersThis should be reworded
which would have a 2S rather than 2R configuration at the molecules' single chiral centerredundant, also a bit confusing since it hasn't been established prior that dextrorotatory = R.
unlike synthetic dl-alpha-tocopherolkeep the terms consistent. Also, is this needed? perhaps saying an S config is theoretically possible but not commercially made gets the point across just fine.
Function
Vitamin E affects gene expressionNeeds to be expanded significantly. A cursory search has turned up a number of sources
Biosysthesis
chemical family of compounds made up of four tocopherols and four tocotrienolsreword
and plants that through mutations have lost the ability to synthesize α-tocopherol demonstrate normal growth.reword sentence, order of ideas is confusion
Deficiency
Dietary recommendations
The Japan National Institute of Health..sentence is clunky
Overall, this section is very well written. I'd love to see more countries represented.
Sources
Worldwide, consumption is below recommendations according to a summary of more than one hundred studies...repeat sentence, cut the preceding sentence or reword.
common form found in the North American dietany other diets/continents?
Metabolism
and all of the vitamin E vitamers are metabolized and then excreted via urine.unclear on what this means. I assume this means un-excreted bile.
so this appears to be a means of disposing of excess vitamin EI would hope urine is an excretory process. Rather redundant info
A rare genetic defect of the TTPA gene results in people exhibiting a progressive neurodegenerative disorder known as ataxia with vitamin E deficiency (AVED) despite consuming normal amounts of vitamin E. Large amounts of alpha-tocopherol as a dietary supplement are needed to compensate for the lack of α-TTPrepetitive, cut
As an example of a result of the preferential treatment, the US diet delivers approximately 70 mg/d of γ-tocopherol and plasma concentrations are on the order of 2–5 µmol/L; meanwhile, dietary α-tocopherol is about 7 mg/d but plasma concentrations are in the range of 11–37 µmol/LInfo is out of place
Testing for levels
Research Rename section to 'health effects' or something in that same vein
For the conditions described below...What is the purpose of this paragraph. It reads more like a disclaimer than a wiki article.
The European Food Safety Authority (EFSA) reviews proposed health claims for the European Union countries. As of September 2022,, EFSA has not evaluated any vitamin E and cancer prevention claims.missing citation
There are a number of instances where I'd love to see more coverage on other countries, or at least mention that other countries do not have dietary recommendations. On a broader scale, I am concerned that there is a no 'function' section. The Anti-oxidant function is buried in the chemistry section and the specific functions are spread amongst the entire article. This make it somewhat difficult to get a read on what Vitamin E actual does. This review was a beast but here are the first set of edits. I'll put this on hold but there is going to be some serious legwork ahead.
