Natural minerals originate as elements in the earth. Living beings cannot make minerals. Humans consume minerals from eating plants and animals. Plants take up the natural minerals from the soil, and herbivorous animals eat the plants. Minerals are also present in the water supply. The amount of minerals consumed depends on the soil and water content; this varies geographically.
