- 0.9% of products don't disclose an amount because Vitamin E is declared inside a proprietary blend.

Search interest over time
How often people search for vitamin e on Google, US only, the last 5 years. This is public interest, not DSLD label data — a spike here doesn't necessarily line up with anything on this page, and Google's own index (100 = that term's peak popularity in the chosen window) is relative, not an absolute search-volume count.

Forms explained
Natural RRR-alpha-tocopherol has roughly double the human bioavailability/tissue retention of synthetic all-rac-alpha-tocopherol -- the basis for FDA's 1mg-natural=2mg-synthetic label-claim conversion.
Source: Burton GW et al. 1998, Am J Clin Nutr 67(4):669-84, PMID 9537614
Ester efficiently hydrolyzed to free tocopherol on absorption; same natural-vs-synthetic bioavailability edge applies.
Source: Burton GW et al. 1998, PMID 9537614
Same rationale as the acetate ester -- esterification does not meaningfully change post-hydrolysis bioavailability; natural-form advantage over synthetic still applies.
Source: Burton GW et al. 1998, PMID 9537614 (acetate esters); NIH ODS Vitamin E fact sheet / IOM 2000 for succinate ester equivalence
Synthetic all-rac form has roughly half the biological activity/tissue retention of the natural RRR form, explicitly reflected in FDA's 2:1 label-claim discount.
Source: Burton GW et al. 1998, PMID 9537614
A mixed alpha/beta/gamma/delta blend has different overall biological activity than isolated alpha-tocopherol (RDA/label math counts only the alpha fraction), and no comparative-potency study for this specific commercial blend was located.
Source: NIH ODS Vitamin E fact sheet (IOM 2000): only alpha-tocopherol counts toward requirements; no comparative-potency study of mixed blends located
Reference values
- RDA (adult): 15 mg
- Tolerable Upper Intake Level (adult): 1000 mg — Applies to any form of supplemental alpha-tocopherol. 1,000 mg/day of any supplemental form = ~1,500 IU natural or ~1,100 IU synthetic (NIH ODS); the UL is set on the mass of supplemental alpha-tocopherol of any form, not on RRR-equivalent label-claim mg.
- Studied clinical dose range: ?–180 mg
- Klein EA et al. 2011 (SELECT trial), JAMA 306(14):1549-1556, PMID 21990298 -- 400 IU/day (180mg) synthetic all-rac-alpha-tocopheryl acetate significantly increased prostate cancer risk (HR 1.17, 99% CI 1.004-1.36) vs placebo in 35,533 healthy men at median ~7yr follow-up (the first 2009 report at 5.5yr was not significant, HR 1.13). No single pinned low-dose comparator RCT was confidently identified -- left null rather than guessed.
- Note: IU->mg conversion depends on natural vs synthetic form: 1 IU natural (RRR-alpha- tocopherol, incl. esters) = 0.67mg; 1 IU synthetic (all-rac-alpha-tocopherol, incl. esters) = 0.45mg (FDA Guidance for Industry, Aug 2019, Tables 5-6). Equivalently, 1mg natural label-claim = 2mg synthetic.
