Calcium, iron, iodine, and magnesium are important minerals that regulate various bodily functions. Calcium forms bones and teeth and controls heart, blood, and nerve actions. Iron activates blood to carry oxygen throughout the body as part of hemoglobin. Iodine regulates temperature and is necessary for mental development and hair color. Magnesium aids in bone and tooth formation and allows for muscle contraction. A deficiency in any of these minerals can lead to issues like anemia, goiter, stunted growth, or physical retardation.

USES

3. Major mineral items
IRON
*Activates blood to carry oxygen
to the body parts.
*Acts as a part of hemoglobin
*Deficiency causes anemia

4. Iodin
*It regulates temperature
*For mental development and
coloring of hair
*Deficiency create goiter,stunted
growth

5. Magnesium
*Bones and teeth are
formed by magnesium
*Deficiency limits
muscle contraction

6. Calcium
*Formation of bones
and teeth
*It controls the actions
of heart,blood,nerves.
*Physical retardation
take place in its
absence.
