1 serving daily (as directed on label, typically 1-2 tablets/capsules)
With breakfast, With lunch (if GI sensitive)
Capsule or softgel
100-400 IU daily (natural d-alpha-tocopherol)
With fat-containing meal, Any time of day
Natural mixed tocopherols (d-alpha, beta, gamma, delta)
Combined intake above 400 IU/day has been associated with increased all-cause mortality in meta-analyses (though causality debated). Anticoagulant effect is clinically meaningful at combined doses above 400mg/day, especially with anticoagulant medications.
Keep combined vitamin E below 400mg/day (approximately 600 IU). Avoid combining with blood-thinning medications without medical supervision. Use mixed tocopherol forms rather than isolated alpha-tocopherol to avoid tocopherol displacement.

Vitamin E supplementation in pregnancy
The Cochrane database of systematic reviews (2015) · Meta analysis · n=19023
Women supplemented with vitamin E in combination with other supplements compared with placebo were at decreased risk of having a placental abruption (RR 0.64, 95% CI 0.44 to 0.93, seven trials, 14,922 participants, I² = 0%; high quality evidence).
Based on COSMOS trials (n=5765) showing equivalent of 2.0 years cognitive decline prevention. Effects most pronounced in those with cardiovascular disease. Study duration was 3 years. Effectiveness reflects conservative interpretation of memory and global cognition improvements.
Based on meta-analysis showing 14.14 mmHg reduction in SBP. Effect size is modest and bleeding risk increases above 400 IU daily. Natural d-alpha-tocopherol preferred over synthetic forms.
AI-estimated from published studies. Interpret as directional guidance.
Multivitamin has a higher evidence score (6/10 vs 5/10) and wins in 3 of 3 categories.
Both Multivitamin and Vitamin E score equally (50) for reduce inflammation.
Combined intake above 400 IU/day has been associated with increased all-cause mortality in meta-analyses (though causality debated). Anticoagulant effect is clinically meaningful at combined doses above 400mg/day, especially with anticoagulant medications. Keep combined vitamin E below 400mg/day (approximately 600 IU).
