(Changes source to company and adds details on board changes)

Sept 28 (Reuters) - Hain Celestial Group Inc, under pressure from activist investor Engaged Capital LLC, said it would appoint six new directors to its board, including the hedge fund's founder, Glenn Welling.

Shares of the company, which makes organic foods such as Health Valley bars, Walnut Acres tomato sauces and Tilda basmati rice, rose 6.4 percent to $43 in premarket trading on Thursday.

Hain's board will be reconstituted to comprise 11 directors, with all but one independent, and three current board members will not stand for re-election, the company said.

Engaged Capital in June disclosed it had a 9.9 percent stake in Hain.

The Wall Street Journal, which first reported the news, said Hain will also form a group of directors to examine strategic alternatives. (http://on.wsj.com/2fSO4Pc)
