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. 

You can use some products. Many of the shakes contain milk ingredients, which are not lactose-free. If you are lactose intolerant, you should use products that indicate "lactose-free" or “free from dairy” on the label. Currently, the water-mixable Instant Formula 1 Vanilla Dream and Chocolate are labeled as "lactose-free". Also, the Formula 1 Allergen-Free Healthy Meal Nutritional Shake Mix is “free from dairy” and other allergens.
