NUTRIENT-ENHANCED water drinks are ''expensive lolly waters'' with exaggerated health claims, says a damning review by the consumer group Choice.

Choice says some of the drinks, with names such as Nutrient Water, Smart Water and Vitamin Water, contain enough sugar in a 500 millilitre bottle to provide the average Australian woman with a third of her recommended daily intake.

It says many of the nutrient-enhanced drinks spruik ''over-the-top health claims'' - touting ''nature approved ingredients'' and ''natural flavours'' that mean little.

A Choice spokeswoman, Ingrid Just, said the labelling on several nutrient drinks created the impression they are healthy when often an apple and a glass of water is more beneficial.

''The marketing of these products is often quite tongue-in-cheek, and we are not against creative copy, but when it comes to possibly misleading consumers about the health benefits of these drinks … that's when we start to get concerned,'' she said.
