Has the glycemic index been determined for all Herbalife® products?

No. The glycemic index (GI) has not been determined for our products. However, Formula 1 is considered to have a low GI since the carbohydrate source is fructose. Fructose is categorized as a low GI sugar which, when combined with protein and fiber (such as in our Formula 1 shake), can also help provide a lower GI.
