European Probiotics specialist Probi has acquired a stake in US supplements firm Vital Nutrients, in a deal which will see the companies collaborate on new product development. 

Probi's probiotic "significantly decreased" plasma levels of two inflammatory markers coupled to acute stress in study, with the firm planning further research into the gut-brain axis.

Probiotics player Probi will use deals and organic growth to double its sales over five years; Belgium's Oysershell strikes deal with Bayer for head-lice brand; and Doetsch Grether acquires Swiss supplements firm Vita.

With its focus firmly on oncology, the Swedish biotech, and its outgoing chief, believe the company now needs someone with more scientific skills in the CEO role.
