March 31 (Reuters) - Canada's GLG Life Tech Corp swung to a quarterly loss as costs soared, but the sweetner maker said China's plan to tackle a sugar shortage and address health concerns over too much sugar consumption would bode well for future growth.
The company -- which supplies Stevia, a natural, zero-calorie sweetener used in food and beverages -- said it plans to provide China's Sugar Reserve with a blend of sugar and Stevia.
GLG forecast higher revenue of C$160-C$200 million and capital expenditures of C$5-C$10 million for 2011. In 2010, it posted total revenue of C$58.9 million.
For the October-December quarter, GLG posted a net loss of C$3.2 million, or 12 Canadian cents a share, compared with a net income of C$488,000, or 2 Canadian cents a share, last year.
Revenue rose 46 percent to C$19.3 million.
Cost of sales was $15.6 million compared with $8.3 million in the same period last year.
The company said pricing incentives given to new distributors raised the cost of sales as a percentage of revenue.
Vancouver, British Columbia-based GLG Life's shares, which have gained nearly 27 percent in value since reporting a third-quarter profit in November last year, closed at C$10.28 on Wednesday on the Toronto Stock Exchange.
