Nichols, the owner of soft drinks brand Vimto, has acquired healthy beverage maker VitHit in a deal worth €75 million (£64 million), created by former professional rugby player Gary Lavin.
Mr Lavin, who played for Leinster and Harlequins, will step down following the sale of the business. He launched the brand in Dublin 25 years ago as a healthy alternative to sugary sports drinks.
