had changed its name from Herbalife Ltd. to Herbalife Nutrition Ltd. The company also announced that its shareholders had approved a two-for-one stock split. In January 2019, Herbalife announced that it was replacing Goudis after learning of comments he had made before taking over as CEO that was “contrary to the company’s expense-related policies and business practices” and inconsistent with the company's standards and culture.” Former CEO Johnson subsequently took over the role on an interim basis. In March 2020, John Agwunobi was named as its next chief executive. Agwunobi departed Herbalife Nutrition in October 2022 and Michael O. Johnson was named Chairman and interim Chief Executive Officer. Products Herbalife Nutrition's products include weight-loss and protein shakes, as well as protein bars, teas, aloes, vitamins, and sports hydration, energy, and personal care products. The company's original product is the Formula 1 protein shake, a soy-based meal-replacement shake. The product debuted in 1980 and, as of 2015, was the company's best selling product accounting for nearly 30% of total sales. Herbalife's products are produced at the company's five manufacturing facilities in the U.S. and China, as well as by third-party manufacturing partners. The company's production process is based on a 'seed to feed' strategy, which the company initiated in the 2010s that allows it to trace where the ingredients in its nutritional products originated. Since 2013, the company has operated a botanical extraction facility in Changsha, Hunan Province, China. The facility produces botanical extracts, including teas, guarana, chamomile, broccoli, and bilberry, for use in many of the company's products. Before extracts are processed, they undergo a botanical identification program and are tested several times throughout the production process. The processed raw materials from the extraction facility are used at all of the company's branded manufacturing facilities as well as by its partners. As of 2015, 58 percent of the company's nutrition products were manufactured at Herbalife-owned facilities. In China, the company's manufacturing sites are located in Suzhou and Nanjing. In the U.S., the company has manufacturing facilities in Lake Forest, California and Winston-Salem, North Carolina. Herbalife's claims of health benefits from its products have met scrutiny from the medical community, consumers, and government agencies. In 2008, Herbalife was sued after laboratory tests indicated that levels of lead in several Herbalife products were in excess of California state law and could lead to liver problems over an extended period of time.
