Citric acid in exante choc orange bars?

[ItIsLucy]

As title says - I've just noticed that there's citric acid in the Exante choc orange bars (which makes sense as they're orange flavour!) but as I thought we weren't supposed to have any citric acid, I'm a bit nervous about having any more! Can anybody advise? Thank you!

Dont worry theres literally a trace in the bars, not like coke etc

Its totally safe
