Swiss pharmaceuticals group Roche will sell its vitamins division to Dutch chemicals group DSM, reported the Badische Zeitung today [Wednesday]. The paper says Roche has decided to sell off the vitamins unit because it is less profitable that its other operating units. The vitamin division is worth around SFr3.5bn (US2.2bn$), accounting for approximately 10% of Roche's overall turnover of SFr29bn, reported Dow Jones.
