Vitamin-enhanced and energy drinks do not boost physical or mental health, a new study shows.

Scientists from Canada's University of Toronto and Ryerson University studied the products, sold in local supermarkets, especially energy drinks, vitamin waters and juices with added nutrients, most commonly the vitamins B6, B12, C and niacin.

A lot of young people use these kinds of drinks hoping to gain vitamins, improve mood or concentration, The Daily Mail reports. 

The findings of researcher, however, have shown that consumers stand to reap little or no benefit from the nutrient additions, while their labels indicate the advantages of nutrient additions.

The brands are aimed at young adults, and the drinks, promising vigour, energy, concentration or recovery, attract them. Specialists say, their ingredients do not 'address existing nutrient inadequacies in the population'. They mention that measures are needed not to mislead consumers and avoid practically useless drinks.
