Vitamin E Intake Calculator
Vitamin E mg from food and pills against RDA.
What it does
Vitamin E guards cells as an antioxidant on milligrams a day: 15 for adults, 19 nursing, with a 1,000 ceiling. Nuts lead food sources while pills span hundreds.
The tool above takes nut and greens servings with pill IU by life stage. It returns total mg, the RDA share, and the safety verdict.
The default adult with nuts plus greens totals 11 mg, or 73% of RDA, within range. The 1200 IU pill case converts to 804 mg, still inside the ceiling.
NIH supplement guidance fixes the 15/15/19 ladder with the 1,000 adult limit. Federal labeling repeats 15 mg as the Daily Value behind panels.
Natural IU converts at 0.67 with synthetic lower, so labels decide pill math. Blood thinner users treat high doses as medical decisions, not arithmetic.
How to use
- Pick the life stage.
- Type nut servings.
- Type greens servings.
- Type supplement IU.
- Read total first.
- Read share and safety beside it.
Formula
- nuts
- Nut servings near 8 mg each.
- greens
- Greens servings near 3 mg each.
- IU
- Label IU converted at 0.67.
- RDA
- 15 adult and pregnant, 19 lactating.
NIH Office of Dietary Supplements sets adult RDA at 15 mg with 15 pregnancy, 19 lactation, and a 1,000 upper limit. Federal Daily Value rules list 15 mg for labeling. Produce factors are planning estimates; IU converts at 0.67 for natural forms per label math.
Worked example
Example: nuts plus greens
Defaults: adult, 1 nuts, 1 greens.
- Eater: adult, 1 nut serving, 1 greens serving.
- Nuts: 1 x 8 = 8 mg alpha tocopherol.
- Greens: 1 x 3 = 3 mg.
- Total: 8 + 3 = 11 mg.
- Share: 11 / 15 = 73% of RDA.
- Tool shows 11 mg, 73% of RDA, Within safe range.
Reference table
| Group | RDA | UL |
|---|---|---|
| Adults | 15 | 1,000 |
| Pregnancy | 15 | 1,000 |
| Lactating | 19 | 1,000 |
| IU natural | x 0.67 | label math |
Limits
- Estimates; foods vary.
- IU forms differ.
- Not a medical workup.
- Labels beat planning factors.
Common mistakes
- Reading IU as mg directly.
- Ignoring thinner interactions.
- Megadosing past 1,000.
- Counting oils blindly.
- Self treating clotting signs.
Try it yourself
Quick checks. Answers sit tucked under each question.
1,200 IU pill only?
804 mg, 5360% of RDA, within safe range under 1,000.
Nothing logged?
0 mg, 0% of RDA, within safe range but far under goal.
Pill 999,999 IU?
Past 100,000 IU exceeds entry bounds: read the label and retry.
Questions
How much daily?
15 mg adults and pregnancy, 19 lactating, 1,000 upper limit for adults. Pills read IU or mg on labels.
Sources counted?
Nuts near 8 a serving, greens near 3, oils vary. Supplements read exact.
Too much signs?
Bleeding risk climbs past grams a day with blood thinners, plus nausea and headaches.
IU to mg?
1 IU natural is 0.67 mg; synthetic is 0.45. This tool converts natural at 0.67.
Diagnose issues?
No, this estimates intake. Bleeding and clotting questions need clinicians.
Storage losses?
Yes, heat and air degrade it. Fresh nuts and quick cooking keep more.
