In the US, a new chewing gum packed with as much caffeine as half a cup of coffee is set to be launched.
Wrigley's will release its Alert Energy Caffeine Gum, an energy product pitched as a "portable solution" for flagging energy and an alternative to energy drinks, coffee and tea, across the US next month.
AdvertisementOne piece of sugar-free gum contains 40 mg of caffeine - the equivalent of half a cup of coffee, and is available in fruit and mint flavours, the New York Daily News reported.
It follows the footsteps of AeroShot, a caffeine inhaler, received a lot of buzz when it was first announced in 2011.
The portable tube-like device, currently sold in the US, contains 100 mg of caffeine, about the same amount as a large cup of coffee.
The new caffeine gum isn't the first developed to do more than freshen bad breath.
A Swedish chewing gum made with Vitamins A, B1, B6, B12, C and beta carotene, Vigo Gum, claims to help build stronger nails, hair, and healthy, elastic skin, while Trident's Vitality line claims to 'rejuve,' 'awaken' and 'vigorate' with Vitamin C, white tea and ginseng.
