Origin of Ingredient
Vitamin A is found in both plant and animal sources. Animal-based sources include liver, fish oils, and dairy products, which provide preformed vitamin A (retinol). Plant-based sources, such as carrots, sweet potatoes, and spinach, contain provitamin A carotenoids, which the body converts into retinol.
History of Ingredient
The significance of vitamin A was recognized in the early 20th century when researchers identified its role in vision and maintaining overall health. Historically, liver, rich in vitamin A, was used as a remedy for various ailments. As scientific understanding evolved, the importance of this vitamin in immune function and skin health became well-established.
Scientific Makeup of Ingredient
Vitamin A encompasses a group of compounds including retinol, retinal, and retinoic acid, as well as provitamin A carotenoids like beta-carotene. These compounds are essential for vision, as they form part of the visual pigment rhodopsin, and for cellular growth and differentiation. Retinoids and carotenoids also function as antioxidants, protecting cells from oxidative damage.
Studies have demonstrated that adequate vitamin A intake is crucial for maintaining good vision, particularly in low-light conditions, by supporting the function of the retina. Research also shows that vitamin A is vital for immune system performance, helping to ward off infections by maintaining the integrity of skin and mucosal cells. Additionally, vitamin A is essential for skin health, promoting cell production and repair.
Vitamin A is approved for use in food products and dietary supplements in many countries, including the United States, the European Union, and various Asian nations. Legal claims regarding vitamin A include its benefits for vision health, immune support, and skin health. When making specific health claims, ensure compliance with local regulatory guidelines.
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.
