Vitamin D3 - also known as cholecalciferol - has a special status among vitamins because the body can produce it itself when the skin is exposed to sunlight. Therefore, a lifestyle that involves little sun exposure can lead to a vitamin D deficiency. To make matters worse, many people who spend time outdoors use sunscreen for fear of sunburn and rapid skin aging. However, this results in a reduction in vitamin D synthesis in the skin. If the supply of vitamin D through food or the skin's own synthesis cannot be ensured to a sufficient extent, a vitamin D deficiency occurs. This can lead to osteomalacia, among other things.
