Which nutrient does what?
Ten questions. Each one describes a job in the body. Pick the vitamin or mineral that does it. You get the answer and the reason straight away.
You know what it does. Now see where it happens.
This page is from the team behind Body Unpacked: Health Atlas for iPhone and iPad. This quiz gives you the headline for each nutrient. According to its App Store listing, the app draws the whole map:
- Choose one of 44 everyday foods and watch a graph draw itself: food, nutrients, their established roles, and where in the body they happen
- Follow each of 14 nutrients after you swallow it on an animated body map
- Values come from USDA FoodData Central, and each percentage shows the reference it uses
- Missing data is shown as missing, never as zero
- A full text view carries the same information for VoiceOver

A quick way to remember them
Blood: iron carries the oxygen, vitamin K makes it clot, B12 and folate build the cells.
Bones: calcium is the material, vitamin D gets it in, fluoride hardens the teeth.
Signals: sodium and potassium work as a pair across every nerve and muscle cell, with magnesium helping muscles relax.
Protection and repair: vitamin C builds collagen, zinc helps wounds close, vitamins A and E look after eyes and cell membranes.
This quiz is for learning, not for deciding what to take. Ask a doctor or dietitian before starting a supplement.
Questions
Where do the facts in this quiz come from?
They are the established, textbook roles of each nutrient, as described in public references such as the US National Institutes of Health Office of Dietary Supplements fact sheets.
Is this suitable for students?
Yes. It covers the level of nutrient function usually taught in school biology, health classes and introductory nursing courses.
Does the quiz tell me what supplements to take?
No. It teaches what nutrients do. Whether you need more of any of them is a question for a doctor or dietitian.
