Vitamin D and its effects on the body have been the subject of intense research in recent decades, with thousands of published studies.

Vitamin D, also known as Vitamins A, D, E, and K, requires the presence of fat for its Absorption by the body. Its positive role in various pathological conditions has been clarified, and experts now consider it the "Vitamin of the future."

However, it is estimated that more than 1 billion people worldwide suffer from this Vitamin deficiency.

What factors affect the Absorption of Vitamin D?

Although Greece is one of the sunniest countries in Europe, the rates of deficiency and deficiency of Vitamin D are high and unusual for the data of a Mediterranean country.

So what factors inhibit the synthesis of Vitamin D, and which individuals are most at risk?

  • Latitude: The distance of an area from Ecuador is a determining factor in the creation of Vitamin D. This happens as the power of ultraviolet rays decreases significantly depending on what they have in Ecuador. The farther away an area is from the equator, the weaker the UVB rays it receives.
  • Season of the year: The months from April to October are the ones that offer the highest amount of Vitamin D per person.
  • Atmospheric pollution: The atmosphere polluted by various pollutants, from burning hydrocarbons or other materials in a classic European city, is no longer suitable for producing Vitamin D. Air particles prevent the Sun's ultraviolet rays from reaching the surface. Skin and therefore have Vitamin.
  • Various pathological conditions: Obesity, chronic kidney disease, liver failure, use of drugs that increase the consumption of Vitamin D (e.g., anticonvulsants), pathological conditions of the gastrointestinal tract, or due to diseases (such as celiac disease, Crohn's disease), cystic or due to surgeries that remove or bypass parts of the stomach or intestine (e.g., gastric bypass)
  • Time of day: The composition of Longas does not exceed 10-15 minutes.
  • Skin color: The substance that colors the skin is called melanin, a natural pigment produced by specialized skin cells. It is the substance that protects the skin from the Sun's harmful ultraviolet rays. Indeed, it is believed that dark-skinned people may need ten times as much time to produce the same amount of Vitamin D that would be made in lighter-skinned people.
  • Age: The elderly show a 50% reduced production of provitamin D3. Also, the fact that most people dress in many clothes and cover a large part of their body even during the summer months makes the situation even more difficult.
  • The use of sunscreens: For example, a sunscreen with a protection index of SPF30 blocks 97% of harmful radiation (UVB), so the body has incredible difficulty synthesizing Vitamin D when using sunscreens with a very high protection index.
  • Staying indoors: Staying indoors or behind windows for extended periods (e.g., for work or medical reasons) leads to reduced levels of Vitamin D in the body.

Which foods contain Vitamin D?

It is found in fatty fish, Salmon, mackerel, tuna, cod, trout, Sardines, Cod Liver Oil, egg yolk, shrimp, margarine, fortified Cereals,  and dairy products.

Although fatty fish such as Salmon, mackerel, trout, tuna, and Sardines are decent sources of Vitamin D.

How is Vitamin D deficiency diagnosed?

Vitamin D levels in our body are measured by a blood test called 25-hydroxy Vitamin D or 25 (Oh) D3. Its prices are determined as follows:

  • values ​​of 25 (Oh) D3 > 30 ng / ml are considered normal
  • 25 (OH) D3 values ​​of 20-30 ng/ml are considered indicative of Vitamin D deficiency
  • values ​​of Vitamin D

What is Vitamin D deficiency?

  • Anxiety-Depression: Research has shown that psychological fluctuations are associated with a lack of Vitamin D in the blood.
  • Hair loss: Hair Loss or autoimmune gyroid alopecia.
  • Muscle pain: Research has shown that 71% of people with chronic muscle pain have a significant deficiency in Vitamin D may be involved in signaling the body's pain pathways, which could play a role in chronic pain.
  • Back and bone pain: Calcium Absorption, which implies reduced bone density (seen in menopause).
  • Fatigue
  • Common Infections-Vulnerable to Vitamin D has an excellent contribution to strengthening the Immune System. Its deficiency has been shown by studies to be responsible for frequent infections of the upper and lower respiratory tract.

What Health Problems Can Vitamin D Deficiency Cause?

Vitamin D deficiency can contribute to bone loss, leading to osteoporosis and fractures (broken bones).

Severe Vitamin D deficiency leads to osteomalacia. Osteomalacia causes weak bones, pain, and muscle weakness.

Researchers are now studying Vitamin D and its possible links to various Severe medical conditions, including diabetes, high blood pressure, and autoimmune diseases such as multiple sclerosis. Of course, the findings so far are incomplete, and further studies are needed to draw Safer conclusions.

How can a Vitamin D deficiency be treated?

High-risk groups should be screened for possible Vitamin levels twice a year. The first measurement should be done after the summer months (September-October) and the Second after the winter (March).

An opinion is that 80-90% of Vitamin D plagues modern society.

The recommended dose of Vitamin recovery treatment is Safe, and usually, its administration has no problems.
