about Vitamin D
    
    
    Vitamin D is a term used to describe a group of fat-soluble vitamins that play an important role in bone health and the regulation of calcium and phosphorus levels in the blood. Vitamin D is also known as cholecalciferol, and is mainly produced via the skin’s conversion of sunlight into a hormone, known as calciferol.
    
    Vitamin D helps to improve bone health by promoting the absorption of calcium, which is needed to form and maintain healthy bones. It is also involved in immune system support, helps protect against muscle weakness and joint pain, and helps regulate cell growth and improves overall health. In addition, Vitamin D is important for healthy skin, hair and nails, and plays a role in the production of hormones, enzymes and proteins.
    
    The risk of Vitamin D deficiency is higher among those living in northern climates, because the sun’s intensity is lower and there is less exposure to its ultraviolet rays. While Vitamin D can be found in fish, eggs, fortified milk and cereals, supplements may be required if levels in the body become too low.
    
    The European Food Safety Authority (EFSA) recommends a daily intake of at least 5 micrograms (μg) of Vitamin D for adults, and of 10μg for children aged 7-10 and 15μg for those aged 11-17. The U.K.’s Department of Health & Social Care also recommends the same levels. In the U.S., the Institute of Medicine recommends 600 IU (International Units) of vitamin D per day for individuals up to 70 years old, and 800 IU for those over age 70.
    
    Symptoms of Vitamin D deficiency are wide-ranging, including tiredness, muscle weakness, joint pain and poor concentration. In more serious cases, low Vitamin D levels can increase the risk of developing rickets and osteomalacia, both diseases that affect the development of bones. If left untreated, poor calcium absorption and weakened bones can occur.
    
    Although Vitamin D can be found in both food and supplements, a healthy diet is the best source. Consuming oily fish such as salmon and mackerel, along with dairy, eggs and fortified foods such as orange juice, is recommended. Additionally, spending some time outdoors each day to increase exposure to sunlight can help synthesize Vitamin D in the body.
    
    A diet adequate in Vitamin D and safe exposure to the sun is an essential factor in ensuring optimal bone health. When everyday living habits cannot provide sufficient amounts of Vitamin D, supplementation may be necessary.
