Choline Intake Calculator
Score daily choline percent and gap from foods by life stage.
What it does
Choline feeds cell walls and signaling. Eggs, meat, and soy carry most of it, and many adults land short without knowing a number.
The tool above scores the day. An adult woman target is 425 mg, so 300 mg from food reads 70.6 % with 125 mg more to find. Targets shift by stage, from 250 mg for young kids to 550 mg for men and nursing mothers.
Food math starts with eggs. One large egg carries near 150 mg, so breakfast sets the tone for the whole score. Meat, fish, and soy fill the rest, while fruits and most veg add little.
Gaps close with swaps, not pills for most people. An extra egg, a soy serving, or a fish dinner covers 125 mg without restructuring the week.
Single days mislead. Training, travel, and skipped meals swing intake, so a seven day average says more than any one tally.
How to use
- Pick life stage: adult woman suits the default.
- Enter food choline in mg from labels or FoodData.
- Read target first.
- Read percent next.
- Read gap and add an egg or soy serving.
- Score a full week before judging.
Formula
- stage
- Life stage setting the target.
- food
- Choline from foods, in mg.
Targets follow Institute of Medicine adequate intakes as listed by NIH ODS. Food mg comes from labels or USDA FoodData entries for the day.
Worked example
Example: adult woman, 300 mg from food
Defaults: adult woman eating 300 mg. These are also the default values, so the page opens on this answer.
- Stage: adult woman, target 425 mg.
- Food: 300 mg from eggs and meat.
- Share: 300 / 425 x 100 = 70.6 %.
- Gap: 425 - 300 = 125 mg more.
- Tool shows 425 mg, 70.6 %, 125 mg more.
Reference table
| Stage | Target | Example score |
|---|---|---|
| Child 4-8 | 250 mg | 200 mg is 80 % |
| Adult woman | 425 mg | 300 mg is 70.6 % |
| Adult man | 550 mg | 400 mg is 72.7 % |
| Pregnancy | 450 mg | 400 mg is 88.9 % |
Limits
- Intake scoring only, not medical advice.
- Targets are adequate intakes, not personal prescriptions.
- Labels and FoodData entries vary by brand.
- Illness and pregnancy needs need clinicians.
Common mistakes
- Scoring one dinner instead of a week.
- Counting coffee and snacks as choline.
- Skipping eggs, then wondering at the gap.
- Mixing mg and grams on labels.
- Treating percent as a diagnosis.
Try it yourself
Quick checks. Answers sit tucked under each question.
Adult man eating 400 mg?
Target is 550 mg. Share is 400 / 550 x 100 = 72.7 %. Gap is 550 - 400 = 150 mg more.
Child eating 200 mg?
Target is 250 mg. Share is 200 / 250 x 100 = 80 %. Gap is 50 mg more.
Questions
How do I score my day?
Divide food mg by the stage target. Here 300 / 425 x 100 = 70.6 %.
What are the targets?
Adult men 550 mg, adult women 425 mg, pregnancy 450 mg, breastfeeding 550 mg, kids 250 mg, teen boys 550 mg, teen girls 400 mg.
Which foods carry choline?
Eggs lead near 150 mg each, then meat, fish, and soy. Two eggs plus a meat serving pass half the day for many adults.
How do I close the gap?
Subtract food from target. Here 425 - 300 = 125 mg more, about one egg or a soy serving.
Does one day decide?
Yes. Coffee, alcohol, and skipped meals shift real days, so score a week, not one dinner.
Does this diagnose deficiency?
No. This page scores intake only. Deficiency signs need a clinician and labs.
