Origin of Ingredient
Vitamin D is unique among vitamins as it can be synthesized by the body through exposure to sunlight. It is also found in certain foods such as fatty fish, liver, egg yolks, and fortified foods like milk and cereals. There are two main forms of vitamin D: D2 (ergocalciferol), found in plant sources, and D3 (cholecalciferol), found in animal sources and synthesized in the skin.
History of Ingredient
The importance of vitamin D was first recognized in the early 20th century when it was identified as the key factor associated with rickets, a disease characterized by weak and deformed bones in children. Since then, extensive research has uncovered its broader role in supporting bone health, immune function, and overall well-being. The discovery of vitamin D’s synthesis through sunlight revolutionized our understanding of nutrition and health.
Scientific Makeup of Ingredient
Vitamin D is a fat-soluble vitamin that functions like a hormone in the body. It is converted into its active form, calcitriol, in the liver and kidneys. Calcitriol helps regulate calcium and phosphate levels in the blood, promoting healthy bone formation and maintenance. Additionally, vitamin D receptors are present in various tissues, indicating its wide-ranging effects on health, including immune function and muscle performance.
Research has shown that vitamin D is crucial for bone health by promoting calcium absorption and reducing the risk of osteoporosis and fractures. Studies also highlight its role in enhancing immune function, with evidence suggesting it helps protect against infections and autoimmune diseases. Furthermore, vitamin D is essential for muscle function, with deficiencies linked to muscle weakness and increased fall risk in older adults.
Vitamin D is widely approved for use in dietary supplements and fortified foods in many countries, including the United States, the European Union, and various Asian nations. Legal claims regarding vitamin D include its benefits for bone health, immune support, and muscle function. Always ensure compliance with local regulatory guidelines when making specific health claims.
Health claims on food supplements in the UK and EU must be authorised, and our technical and quality team checks label wording for compliance before a label is approved.
