How to read this ranking
This page compares Calcium (Calcium, Ca), in mg per 100 g of food.
Chemical forms and measurement methods remain separate. “Not reported” means a value is unavailable, not that the food contains zero. A food’s rank does not determine your individual needs or diagnose a deficiency.
This NIH fact sheet concerns this nutrient. Its recommended amounts describe daily intake for the stated population, not a 100 g food portion. Keep food and supplement exposure separate as the source specifies.

What is calcium and what does it do?
Calcium is a mineral your body needs to build and maintain strong bones and to carry out many important functions. Calcium is the most abundant mineral in the body.
Almost all calcium in the body is stored in bones and teeth, giving them structure and hardness.
Your body needs calcium for muscles to move and for nerves to carry messages between your brain and every part of your body. Calcium also helps blood vessels move blood throughout your body and helps release hormones that affect many functions in your body. Vitamin D helps your body absorb calcium.
How much calcium do I need?
The amount of calcium you need each day depends on your age and sex. Average daily recommended amounts are listed below in milligrams (mg).
