Pune:The country’s food safety and standards regulator has allowed use of higher levels of caffeine in energy drinks. The set standard of 145 parts per million (ppm) of caffeine has been relaxed up to 320 ppm for energy drinks, said Food and Drugs Administration (FDA) officials on Thursday.

The regulator, however, has stipulated that manufacturers infusing energy drinks with higher amounts of caffeine will have to print warnings such as-—‘caffeinated beverage’, ‘use not more than two cans a day’, ‘ingredients of this product consumed through other sources may also be kept in view’, ‘not recommended for children, pregnant and lactating women’, ‘not for persons sensitive to caffeine,’ and ‘caffeine consumed through this and other sources not to exceed 160 mg per day’—prominently on the label of the energy drink products.
