Sales had halved by 2001, and the drink was redesigned and re invented in March 2003 as "SunnyD". In the United Kingdom, SunnyD was again relaunched in March 2009, with a new formulation containing 70% fruit juice and no artificial ingredients or added sugar.

Did SunnyD change its formula?

To be fair, she was drinking 1.5 litres of the stuff a day but this was the straw that broke Sunny Delight's back. Sales halved, causing the company to have to rebrand in 2003. It was then relaunched again in 2009 with a new formula containing 70 per cent fruit juice and no artificial ingredients or added sugar.

What's wrong with SunnyD?

SunnyD is colored with artificial colors that have been subject to considerable controversy. There's some evidence they may cause developmental disorders, hyperactivity, and thyroid dysfunction. There's also some indications that they may be carcinogenic.
