The hedge fund battle over Herbalife (HLF) intensified on Wednesday as George Soros has taken a large long position in the nutritional supplements maker, according to sources.

Soros' position in Herbalife is one of his top three holdings, sources said.

The hedge fund manager had no comment on the position.

This puts Soros on the side of billionaire investor Carl Icahn, who is also long the stock. Bill Ackman of Pershing Square Capital, meanwhile, is short the stock, telling CNBC earlier on Wednesday that he has not covered a single share of that position.
