Herbalife Ltd. reported strong earnings but lower guidance late Monday. Its stock declined in trading Tuesday morning.

For the third quarter, the Los Angeles-based herbal supplement company reported earnings of $108 million, or 87 cents a share. That represents a 37 percent gain from the third quarter last year, when earnings were $79 million or 63 cents per share.

Analysts expected the company to report a profit of 76 cents a share, according to FactSet.

However, much of the growth came from overseas, particularly in Asia and Latin America. Herbalife cautioned that going forward, volatile currency exchange rates will decrease earnings per share by about 10 to 12 cents per quarter.

By mid-day Tuesday, shares of Herbalife traded at $57.01, a decline of $5.35 or 9 percent on the New York Stock Exchange.
