  1. It is easy to get enough vitamin D from a balanced diet – Myth

  1. Just go out at any time of the day and I will have enough Vitamin D - Myth

Vitamin D is also called solar vitamin, as it is obtained mainly from the sun. However, this is not always enough. It very much depends on factors such as season, time of day, clouds, skin pigment or the use of sunscreen.

For example, people who have darker skin are not able to take in as much vitamin D through the sun as people with paleer skin.

Experts have agreed that a sufficient amount of vitamin D is enough for about 15-30 minutes daily staying outside (between 10:00 and 16:00). Of course, the sun should fall directly on the skin, so clothing and sunscreens prevent it.

On the other hand, you need to watch out for skin cancer. Sunlight increases the risk of skin cancer and also promotes and makes wrinkles more visible.

  1. Vitamin D supports the immune system – Fact

To keep your immune system functioning as it should, make sure you have enough amount of Vitamin D. It actually helps to reduce harmful inflammatory reactions in the body and increases the production of immune cells.
