Vitamin D is a fat-soluble
vitamin found in certain foods and is manufactured in the skin as a
result of direct exposure to sunlight. The liver and kidneys convert
vitamin D from food sources or sunlight to its active form,
calcitriol. Vitamin D helps the body maintain healthy levels of
calcium and phosphorus and is therefore essential for building and
maintaining healthy bones. Calcium, which is the principal element
in bone, can be absorbed by the body only when vitamin D is present.
Vitamin D and calcium are involved in many body functions, including
keeping the immune and nervous systems healthy.

Two forms of vitamin D,
cholecalciferol and ergocalciferol, are naturally found in foods and
are added to milk. It is important to note that the milk used to
make yogurt and cheese is usually not vitamin D fortified. Foods
sources of vitamin D include the following: cod liver oil, fatty
fish such as salmon, mackerel, tuna, sardines, herring; Vitamin D
fortified milk and cereal, eggs. |
Rickets, a vitamin D deficiency
disease responsible for softening and weakening bones in children,
used to be quite common but now is rarely seen in countries that
have adopted the practice of fortifying milk products. |
