As with so many market statistics, estimates of the size of the sports nutrition market vary widely, depending on types of products included and distribution channels monitored. Nutrition Business Journal, for example, reported that sports nutrition products—in the form of supplements, bars and drinks—racked up $4.7 billion in consumer sales in 1999, a 10% rise over 1998. Slightly over half of this category consists of sports beverages.
In contrast, a Frost & Sullivan report places revenues from the U.S. sports and fitness nutrition market at nearly $2 billion in 2000, and projects it to reach nearly $4.5 billion by 2007.
