The independent soft drinks maker rolls out the new design across its portfolio this month in what it called a "very competitive fixture".
Cues highlighting the 100% natural, sugar-free content have been added, alongside a new 'one of your five-a-day' message. The new Feel Good logo has been made bolder to increase emotional resonance with consumers, MD Dave Wallwork said.
"This refresh is about maximising the positives the brand has, rather than fixing any problem with the design," he said, adding that Feelgood was hearing "more positive noise" over consumer confidence.
"People have had enough of the recession and are looking forward to heading out of grim times and into the summer."
