Vitamin A: Sources, benefits & deficiency


Vitamins are crucial for building, repairing and maintaining healthy tissues and cells, and vitamin A is particularly important for vision, skin and bones. Also known as retinol (because it produces the pigments in the retina of the eye), vitamin A is a fat-soluble nutrient. This means it’s absorbed into the body with dietary fat, and then stored in body tissue for later use. 

Taking big doses of vitamin A can be toxic, but your body only converts as much as it needs. You can get vitamin A naturally from foods or take it in supplement form. It has several functions, from helping the body’s immune system to fight against illness and infection, to supporting healthy vision, teeth, skin and skeletal and soft tissue.
