Vitamin D is an essential nutrient that plays a crucial role in maintaining healthy bones and teeth. It helps the body absorb calcium and phosphorus, which are essential minerals for bone health. Without adequate levels of vitamin D, the body cannot properly absorb calcium, leading to weak bones and an increased risk of fractures.
In addition to its role in bone health, vitamin D also helps support the immune system and may have protective effects against certain types of cancer, autoimmune diseases, and cardiovascular disease. However, many people do not get enough vitamin D from their diet or exposure to sunlight, which is why supplementation is often recommended.
Supplementing with vitamin D is particularly important for those who live in northern latitudes like Ireland, where there is less sunlight, or for those who spend most of their time indoors. Older adults and people with dark skin may also be at increased risk of vitamin D deficiency.
While it is possible to get vitamin D from some foods, such as fatty fish, egg yolks, and fortified dairy products, it can be challenging to get enough through diet alone. By supplementing with vitamin D, individuals can ensure that they are getting the recommended daily intake of this essential nutrient, which can help support bone health and overall well-being.
