Vitamin A (Retinol)
Vitamin A, also known as retinol, is a fat soluble vitamin. It is found in the diet in two distinct chemical forms; retinoids are found in animal foods such as meat, poultry, fish and dairy products, while cartotenoids, such as beta-carotene, are found in plant foods, such as fruit and vegetables. Since it's discovery in 1913, the significance of vitamin A to human health has become increasingly apparent. It is known to serve crucial roles in a variety of systemic functions, helping to keep the skin and mucous membranes (the smooth muscle tissue that lines the eyes, nose, mouth, throat, vagina and rectum) smooth and supple and vital for optimal immune system function, vision, reproduction, growth and development.
