Get to Know Vitamin D: Vitamin D is an organic substance that belongs to both vitamins and hormones. It has been nicknamed "the sunshine vitamin" and is naturally produced by our body when sunlight comes into contact with our skin.

Biochemistry: Vitamin D is fat-soluble and affects the function of nearly 2,000 different genes. Its most important properties include:

• regulating the absorption of calcium and phosphorus
• facilitating the function of the immune system
• supporting the proper development of bones and teeth
• resisting certain diseases

Vitamin D can also play a crucial role in:

• reducing the risk of multiple sclerosis
• reducing the risk of heart disease
• reducing the risk of developing flu symptoms

Deficiency: Vitamin D deficiency has been observed in Greece mainly due to:

• Skin pigmentation (in Mediterranean countries, darker skin hinders its absorption)
• not consuming foods that contain vitamin D, as the main fat in the diet is olive oil

Sources of intake and recommended intake: We can get vitamin D from foods such as:

• salmon
• sardines
• egg yolk
• shrimp
• fortified cereals
• fortified orange juice

If we do not meet our daily needs, it is good to take a vitamin D supplement. According to the Institute of Food and Agricultural Sciences, the amounts of vitamin D we should take daily are:

• Children and teenagers: 600 IU
• Adults up to 70 years: 600 IU
• Adults over 70 years: 800 IU
• Pregnant and breastfeeding women: 600 IU
