Introducing The Role Of Vitamin D And Abundant Foods

Role Of Vitamin D and foods

I will write about vitamin D. Vitamin D is also associated with the prevention of influenza. I will write about the outline, function, foods contained, etc.

Types of vitamin D

There are six types of vitamin D, D2 to D7, but since D4 to D7 are rarely contained in foods & have low activity, vitamin D2 (ergocalciferol) & vitamins generally show high bioactivity. It is roughly divided into two types: D3 (Cholecalciferol).

Vitamin D absorption and function

The main physiological effects of vitamin D are normal skeletal and tooth growth promotion. In addition, it promotes the intestinal absorption of calcium and phosphorus in the small intestine and regulates the blood calcium concentration to be constant so that it has the function of normalizing nerve transmission and muscle contraction.

The following is a summary of the functions of vitamin D in the body.

It enhances the absorption of calcium and phosphorus in the small intestine, maintains the concentration in blood, and promotes the deposition on bones and teeth.

  • It helps the kidneys recover minerals.
  • Improves muscle function.
  • Helps absorb vitamin A.
  • It is involved in the regulation of immunity.

In addition to these, in recent years, attention has also been focused on the effects on cancer, the effects on influenza, and measures against Parkinson’s disease and dementia.

About vitamin D deficiency

Vitamin D deficiency reduces calcium absorption from the intestinal tract and reabsorption of calcium in the kidneys, resulting in calcium deficiency and hypocalcemia. As a result, bone softening occurs, resulting in osteomalacia in adults, especially pregnant and lactating women. In children, bone growth failure occurs, resulting in poor posture, bent leg bones, and rickets. Old people with low bone mass are more likely to develop osteoporosis and are at increased risk of being bedridden due to fractures. Cenforce 150 and Fildena 150 to improve intimate life.

About overdose of vitamin D

Vitamin D is also a fat-soluble vitamin & is known to cause health problems due to overdose. Taking too much vitamin D causes hypercalcemia, which deposits large amounts of calcium in the walls of blood vessels, kidneys, heart muscle, and lungs. As a result, symptoms such as renal dysfunction, loss of appetite, vomiting, and increased neuroexcitatory activity appear.

Be aware that taking large numbers of vitamin D can deposit calcium in tissues and is contraindicated in patients with hypercalcemia. Calcium concentration in the blood is an indicator of health problems caused by excessive intake of vitamin D.

About vitamin D intake

The standard intake of vitamin D is set to 5.5 μg per day.

We meet the vitamin D requirements, but people with a lifestyle that avoids UV rays (use of sunscreen) and the production of vitamin D in the skin. It may be inadequate for older people with reduced abilities. In addition, blood levels of vitamin D have been shown to change with the seasons (high in summer & low in winter).

Recently, there is also an idea to improve QOL by taking more vitamin D than the standard amount.

Vitamin D intake, foods, and ingredients

Our skin has a vitamin D precursor before it becomes “vitamin D,” & when exposed to ultraviolet rays, “vitamin D” is produced. Therefore, make a habit of going out, such as walking or walking for about 20 to 30 minutes a day.

Vitamin D is abundant in mushrooms, seafood (salmon, trout), eggs, and milk.


To the last, supplements are foods that supplement and supplement nutritional components. The most important thing is to eat in a well-balanced manner. In addition, it is important to move your body, avoid stress, and take a good rest. Currently, the living environment has changed, and things are not going well.
