Vitamin A
Vitamin A supplements provide a convenient way to support daily intake of this essential fat-soluble nutrient. Vitamin A plays an important role in several normal physiological processes within the body, particularly those related to vision, immune system function and skin health.
Vitamin A refers to a group of compounds including retinol, retinal and retinyl esters. These forms are commonly found in animal-based foods such as liver, dairy products and eggs. Plant foods such as carrots, sweet potatoes and leafy green vegetables contain carotenoids such as beta carotene, which the body can convert into vitamin A.
The Role of Vitamin A
Vitamin A contributes to the maintenance of normal vision and helps support the normal function of the immune system. It also contributes to the maintenance of normal skin and plays a role in the process of cell specialisation.
Because vitamin A is a fat-soluble vitamin, the body stores it primarily in the liver and uses it as needed to support normal physiological functions.
Vitamin A Supplements
This category includes a range of vitamin A supplements available in different forms such as tablets, capsules and combination formulas. Some supplements provide pre-formed vitamin A such as retinol, while others provide plant-based carotenoids like beta carotene.
Further information about vitamin A and its role in nutrition can be found in the NHS vitamin A guide.
