As more people avoid sun exposure, Vitamin D supplementation becomes even more necessary to ensure that your body receives and adequate supply.

Vitamin D insufficiency affects almost 50% of the population worldwide. An estimated 1 billion people worldwide, across all ethnicities and age groups, have a vitamin D deficiency.
Cholecalciferol and ergocalciferol are the two forms of vitamin D. Vitamin D is not strictly a vitamin since it can be synthesized by the body. Therefore, vitamin D needs can be met by both dietary intake and endogenous synthesis by sun exposure. The main dietary sources of vitamin D are fatty fishes from cold sea: eel, salmon, mackerel and herring. Other dietary sources are mushrooms and dairy products. Fortified foods including milk/dairy products and cereals may also be important contributors to dietary vitamin D intake in many industrialized countries. For the supply of vitamin D lack of foods containing vitamin D can be compensated by endogenous synthesis from the action of sunlight on the skin. During exposure to sunlight there is a conversion of 7-dehydrocholesterol to previtamin D3, rapidly isomerized into vitamin D3 under body temperature. Vitamin D3 is then excreted into the blood bound to vitamin D-binding protein.
There is a body of literature dating back over 80 years which suggests improvements in physical performance in individuals exposed to UV radiation.
Vitamin D deficiency results in poor muscle function, weakness and myalgia that are reversible upon achieving a vitamin D replete state.
Older adults are at high risk of developing vitamin D insufficiency because of aging. Their skin cannot synthesize vitamin D as efficiently, they are likely to spend more time indoors, and they may have inadequate intakes of the vitamin.
Only a few foods are a good source of vitamin D. The best way to get additional vitamin D is through supplementation.
Vitamin D decreases cell proliferation and increases cell differentiation, stops the growth of new blood vessels, and has significant anti-inflammatory effects.
Several studies are providing evidence that the protective effect of vitamin D on the heart could be via the renin–angiotensin hormone system, through the suppression of inflammation, or directly on the cells of the heart and blood-vessel walls.
Vitamin D is known to help the body absorb calcium, and it plays a role in bone health.
Several studies link low vitamin D blood levels with an increased risk of fractures in older adults, and they suggest that vitamin D supplementation may prevent such fractures—as long as it is taken in a high enough dose.
Vitamin D may also help increase muscle strength, which in turn helps to prevent falls, a common problem that leads to substantial disability and death in older people.
If you purchase vitamin D supplements, you may see two different forms: vitamin D2 and vitamin D3. Vitamin D2 is made from plants and is found in fortified foods and some supplements. Vitamin D3 is naturally produced in the human body and is found in animal foods. There is ongoing debate whether vitamin D3 “cholecalciferol” is better than vitamin D2 “ergocalciferol” at increasing blood levels of the vitamin.
