Chromium Intake Calculator
Score daily chromium percent and gap from foods by life stage.
What it does
Chromium helps insulin work in trace amounts. Whole grains, meat, and broccoli carry it across balanced days.
The tool above scores the day. An adult woman target is 25 mcg, so 20 mcg reads 80 % with 5 mcg more to find. Men target 35 mcg.
Whole grains lead most scores. Breads and cereals stack chromium steadily, with meat and broccoli filling behind.
Needs run tiny. Micrograms, not milligrams, so varied plates rarely gap without restrictive diets.
Weeks beat days. Travel and skipped meals swing any single tally, so average seven before acting.
How to use
- Pick life stage.
- Enter food chromium in mcg.
- Read target first.
- Read percent next.
- Read gap and vary the diet.
- Score a week, not one meal.
Formula
- stage
- Life stage setting the target.
- food
- Chromium from foods, in mcg.
Targets follow NIH ODS recommended intakes. Food mcg comes from labels or USDA FoodData entries summed for the day.
Worked example
Example: adult woman, 20 mcg from food
Defaults: adult woman eating 20 mcg. These are also the default values, so the page opens on this answer.
- Stage: adult woman, target 25 mcg.
- Food: 20 mcg from grains and meat.
- Share: 20 / 25 x 100 = 80 %.
- Gap: 25 - 20 = 5 mcg more.
- Tool shows 25 mcg, 80 %, 5 mcg more.
Reference table
| Stage | Target | Example score |
|---|---|---|
| Child | 15 mcg | 12 mcg is 80 % |
| Adult woman | 25 mcg | 20 mcg is 80 % |
| Adult man | 35 mcg | 30 mcg is 85.7 % |
| Pregnancy | 30 mcg | 25 mcg is 83.3 % |
Limits
- Intake scoring only, not medical advice.
- Labels vary by brand.
- Supplement forms differ in uptake.
- Symptoms need clinicians, not math.
Common mistakes
- Scoring one snack instead of the day.
- Refined everything with no whole grains.
- Supplement megadoses for energy.

Quick checks. Answers sit tucked under each question.
Adult man eating 30 mcg?
Target is 35 mcg. Share is 30 / 35 x 100 = 85.7 %. Gap is 5 mcg more.
Child eating 12 mcg?
Target is 15 mcg. Share is 12 / 15 x 100 = 80 %. Gap is 3 mcg more.
Questions
How do I score my day?
Divide food mcg by the stage target. Here 20 / 25 x 100 = 80 %.
What are the targets?
Kids 15 mcg, teens 25 mcg, men 35 mcg, women 25 mcg, pregnancy 30 mcg, breastfeeding 45 mcg.
Which foods carry chromium?
Whole grains, meat, broccoli, nuts, and brewers yeast. Varied plates cover it.
How do I close the gap?
Add whole grains, meat, or broccoli. Here 5 mcg more closes the day.
Do gaps happen often?
Rarely, since needs run tiny against varied diets.
Does this diagnose deficiency?
No. Intake scoring only; blood sugar signs need clinicians.
