Vitamin D is essential for overall health and is commonly found in fish oils, butter, egg yolks, and leafy green vegetables. However, it can also be produced by the action of UV rays on lanolin found in sheep's wool. Vitamin D3 supplements typically contain vitamin A as well, which may need to be considered in cases where vitamin A intake needs to be restricted, such as during pregnancy.
As we become more aware of the importance of protecting our skin from sunburn and UV rays, the use of sunscreen and protective clothing has increased, leading to a decrease in natural vitamin D production in the skin. This has resulted in a higher prevalence of vitamin D deficiency, especially among the elderly who are less exposed to sunlight.
Vitamin D is unique among essential nutrients as it can be converted into a hormone in the body. Once ingested, vitamin D is converted into 25-hydroxycholecalciferol [25-OH-D3] in the liver, and then into its active form, 1,25 dihydroxycholecalciferol [1,25-(OH)2-D3], in the kidneys. This active form acts as a hormone, regulating various functions in the body, particularly calcium balance and bone health.
