The 51-year-old 'X Factor' boss acquired a taste for the beverage, which is made up of lingonberry, chokeberry, aronia juice and acerola berry, during his recent visit to Miami.
He ordered the concoction's ingredients to be imported from around the world so that he could have it when he is on the road in America watching 'X Factor' auditions.
"He's obsessed with staying healthy and wants to look after himself. The drink is an extension of that," Contactmusic quoted a source as telling the Daily Mirror.
"It is not cheap to make and involves lots of hard-to-buy fruit which we need to take on the road. But for someone like Simon it is not a big deal if it costs a lot.
"He is also eating lots more salad and raw vegetables and has them cut up in his dressing room to try to avoid the chocolate biscuits he used to snack on," the source added. (ANI)
