Vitamin A is found in foods that come from animals such as fortified dairy products, liver, eggs, fortified margarine, fish. Vitamin A is also found in carrots, leafy greens, cantaloupe, broccoli, squash, sweet potatoes, peas. The vitamin A found in foods from animals is used more efficiently and more well-absorbed in the body than the vitamin A found in plants.1
Vitamin A plays an important role in healthy skin, teeth, skeletal and soft tissue, mucus membranes, and skin; as well as preventing or fighting off infections by regulating the immune system. It is also known as retinol because it produces the pigments in the retina of the eye.2
Vitamin A is not normally involved in fluctuations of INR values. As always, consult with your doctor before making any changes to your diet.
