  • Low levels are associated with the risk of several diseases
  • An important vitamin for the normal development of bones and teeth
  • Affects protein synthesis in muscles, which is in turn responsible for muscle size, strength, reaction time, coordination and resilience

D-vitamins are fat-soluble steroid hormones. The most well-known are vitamins D2 and D3. The body does not synthesise vitamin D2 (ergocalciferol) and it can only be consumed with food (plants and some mushrooms). Vitamin D3 (cholecalciferol) is of animal origin (primarily fish), but the largest portion of vitamin D3 is synthesised in the skin upon exposure to ultraviolet light. Ultraviolet B (UVB) radiation in summer around midday on the hands and face for 10-15 minutes results in the synthesis of 800-1000 units of previtamin D3 in the skin, which is enough to cover the daily needs of an adult person. 25(OH)D or calcidiol, the circulating metabolite of vitamin D, is measured in blood. Calcidiol is considered the best indicator of vitamin D supply to the body. Low levels of vitamin D cause the disturbed absorption of calcium and phosphate from the intestines, which in turn increases the risk of osteoporosis. Vitamin D also affects blood clotting, nervous tissue function, helps avoid infectious diseases and diabetes, and has immune modulating, antidiabetic and anti-infective effects, among others. There is an association between vitamin D deficiency (< 50 nmol/l) and the incidence of cancer, multiple sclerosis, various infections, hypertension, rheumatoid arthritis, diabetes and other autoimmune diseases.

Vitamin D also helps to improve physical performance. The effect that vitamin D has on striated muscle cells is the primary way of reducing falls and bone fractures. Striated muscle cells control the position of the body and help to maintain balance. Long-term vitamin D deficiency may impair the physical growth of children, cause lower bone density, and in the case of a severe deficiency, rickets.
