Dutch food and nutrition group Royal Numico has had several enquiries from potential buyers of its troubled US food supplement chain GNC, according to company CEO Jan Bennink.

Bennick also acknowledged that the sale of the US unit could leave Numico vulnerable as a takeover target itself, reported Reuters.

For several years, Numico was the world’s biggest food supplement maker but is now shifting focus to its former core businesses of baby food and hospital feeding.

Bennick is also selling another US unit Rexall Sundown, leaving Numico with its highly-profitable core business that could become a takeover target.

“You are obvious prey for somebody (if GNC goes) – you’re a small company, your market cap is small…somebody will start looking at you,” Bennink told Reuters in an interview.

“It’s all about timing…If you possibly divest GNC, how do you make sure your core business is really performing in a way that you can show your shareholders that it is better as a stand-alone rather than as part of a bigger entity,” he said.
