Taking daily multi-vitamins may not have the benefits we think. 

British GP James Le Fanu has sparked a debate after suggesting even tiny amounts of added vitamins exceed what most people require. 

Nutritionist Nikki Hart says taking copious amounts of vitamins could actually do more harm than good. 

She told Ryan Bridge people think they need to up their intake over winter, but a balanced diet on its own is usually enough. 

Hart says instead of remembering to take lots of supplements, often the answer is just having an orange.
