Vitamin A helps to support your normal iron metabolism, immune system and bone health. Although you should be able to get all the vitamin A from the foods you eat sometimes you may need a supplement to support your intake. Taking vitamin A can also support healthy looking skin, a supplement may be beneficial in a diet where dairy products may be limited. Please note you should not take supplements as a substitute for a varied balanced diet or a healthy lifestyle. Always read the label. Ask your local pharmacist for advice.
