NOS Energy Drink is named after a brand of Nitrous Oxide, and is popular with car and racing enthusiasts.

We just received a tip that NOS has lowered the caffeine content of their energy drinks from 260mg to 160mg per 16 fl.oz. can.

It looks like some versions are now 160mg, but others are still 260mg/can like Charged Citrus and Loaded Cherry

However there still may be some older product still in stock at some locations. The original NOS Energy Drink is grapefruit/citrus flavored and comes also in a 22 fl.oz resealable bottle.

Other flavors of NOS include:

  • NOS Zero- sugar-free version (sweetened with ace-k and Splenda) : 160mg of caffeine
  • NOS Loaded Cherry: 260mg of caffeine
  • NOS Grape: 160mg of caffeine
  • NOS Charged Citrus: 260mg of caffeine
  • NOS Active (non-carbonated sports drink): 122mg/12 fl.oz. bottle.

NOS is manufactured by the High Performance Beverage Company. This is owned by Fuze Beverages LLC, which has now been purchased by Coca-cola.

Note: Consumer Reports r tested NOS and they found it to only contain 224mg of caffeine per can instead of the 260mg NOS used to have.

Perhaps the recent increased FDA scrutiny concerning the caffeine in energy drinks is why NOS adjusted their caffeine amounts to more moderate levels.
