In December 2008, the U.S. Food and Drugs Administration (FDA) stated it had no question regarding the conclusion of expert panels that rebaudioside A is Generally Recognized as Safe (GRAS) for use as a general-purpose sweetener for foods and beverages. Rebaudioside A is a stevia sweetener isolated and purified from the leaves of the stevia plant.
In June 2009, the FDA gave the same assent to the conclusion of an expert panel regarding another stevia glycoside extract with high rebaudioside A content. It was given the green light as a tabletop sweetener. Similar GRAS notifications are before the FDA for other steviol glycoside extracts isolated and purified from stevia rebaudiana.
In Europe, stevia is approved as dietary supplement and is awaiting clearance as a sweetener. The Europen Food Safety Authority (EFSA) is currently conducting a safety assessment of other stevia-based products.
In Canada, stevia is sold as a natural health product.
Stevia by this time has already a long history of use in several countries, including Korea, Mexico, Taiwan, China, Russia, Australia, Argentina, New Zealand, Colombo, Peru, Uruguay, Brazil and Malaysia.
