Stevia Extract

Stevia extract is a high-intensity sweetener derived from the leaves of the Stevia rebaudiana plant. The sweet compounds, called steviol glycosides, are extracted from the leaves and then purified. This process results in a sweetener that is many times sweeter than sugar.

Manufacturers use stevia extract as a sugar substitute to reduce the calorie content of foods and drinks. It is commonly found in products marketed as low-calorie or sugar-free, such as diet beverages, yoghurts, confectionery, and tabletop sweeteners. Its intense sweetness means only small amounts are needed.

Steviol glycosides are authorised food additives in Great Britain and are listed on the Register of Food Additive Authorisations. The European Food Safety Authority (EFSA) has evaluated steviol glycosides and established an acceptable daily intake (ADI). Research into the health effects of stevia extracts is ongoing, with some studies exploring potential benefits for blood sugar management, while others examine its impact on gut microbiota. Evidence is mixed and requires further investigation.
