Vitamin D promotes
the absorption of calcium in the bones

How does Vitamin D work?

Vitamin D is a fat-soluble vitamin, synthesized - in part - by the body. The two forms of vitamin D are vitamin D2 and vitamin D3 (cholecalciferol and ergocalciferol respectively). Both perform almost the same function in the body. Sunlight is the main source of vitamin D. The exposure to sunlight in fact allows the skin to produce this vitamin.

Vitamin D is important for maintaining strong bones and teeth. In fact, it aids in the absorption of minerals like calcium and and phosphorus in the body. Vitamin D also plays an important role in the proper functioning of the muscles and the maintenance of high levels of resistance in the body.

Vitamin D in the diet

The amount of vitamin D produced from the skin is not sufficient for all individuals. Therefore, we also need to take vitamin D through our diet. This vitamin is present only in animal products such as meat, fish and eggs. Often, vitamin D is also added to vegetable fats, margarine and fats for cooking.

Lack of vitamin D

One of the functions of vitamin D is to promote the absorption of calcium in the bones. Any deficiency of vitamin D does not allow adequate absorption of calcium in the bones, sometimes resulting in osteomalacia (weakening of the bones). A prolonged deficiency of vitamin D can also cause osteoporosis. Bones become more fragile and that increases the risk that they break more easily.

Excess of Vitamin D

An excess of vitamin D is very unlikely. In the case of long-term use of a high quantity of vitamin D, higher than 100 micrograms per day, damage may be caused to the heart, kidneys and blood vessels. Among the possible symptoms are nausea, drowsiness, lack of appetite and constipation.

Following the placement of a gastric band or sleeve

If you have recently undergone a gastric band or sleeve procedure, it is essential to take a quantity of vitamin D of between 5 and 20 micrograms per day. This value corresponds to 100-400% of the Recommended Daily Allowance.

Because of changes made to the small intestine as a result of this type of intervention your need for vitamin D increases. However, vitamin D is absorbed in the section affected by the surgery. Therefore, it is necessary to assume an amount between 20 and 60 microgram daily, ie including between 200 - 1200% of the recommended daily requirement, to provide your body with an adequate daily intake of this vitamin.
