Herbalife Zinc Throat Lozenges Are Not Dietary Supplements, FDA Says

Herbalife International's Zinc & Echinacea Throat Lozenges do "not appear to meet the statutory definition of a dietary supplement contained in 21 U.S.C. 321(ff) [of the FD&C Act], and therefore, can not be marketed as a dietary supplement," FDA told the firm in a Nov. 16 "courtesy" letter.
