New Delhi/Mumbai Reigning cola brands Coke, Thums Up and Pepsi and energy drinks such as Red Bull are set to lose a bit of their fizz with the government planning to make it mandatory for caffeinated beverages to flash a statutory warning stating they are not the ‘the right thing’ for certain sections of the population.

The Union health ministry may soon ask manufacturers of caffeinated drinks to carry the warning ‘Not recommended for children, pregnant or lactating women, persons sensitive to caffeine’ on the principal display panel of their products in a typeface sufficiently large and bold so that the message doesn’t go unnoticed.
