Vitamin D and Body System Health
Vitamin D and Body System Health
Vitamin D is one of the fat-soluble vitamins. It is found in milk, salmon,
eggs, cheese, fortified cereals, beef, and tuna. It can also be made in the
skin, when a person is exposed to sunlight. Once it is produced in a
person’s skin, it must be converted to its most active form in the body by
the liver and kidneys. Once activated, vitamin D stimulates the absorption
of calcium and phosphorus in the gut. It is essential for the maintenance
of adequate calcium levels in the body. Calcium is necessary to
maintain strong bones.
A recent study highlighted the role of vitamin D in the maintenance
of body systems. The reviewer highlighted the role of vitamin D as being
essential in the regulation of the immune system, insulin secretion, heart
function, blood pressure, muscle strength, and brain function. The recommended
daily intake for adults aged 51 years and older is 400 units per
day. Taking too much can cause nausea, vomiting, constipation, weakness,
and weight loss. Vitamin D deficiency is associated with an increased
risk of falls, decreased muscle strength, and increased risk of
certain cancers.
