Stevia is a 100% natural sweetener, which is completely safe for everyone. It has been used as a sweetener in Japan and South America for decades. Today, stevia has been approved by major food authorities across the globe.
The WHO's Joint Experts Committee on Food Additives has also approved an acceptable daily intake of steviol glycosides of up to 4 mg/kg of body weight.
In the United States, high-purity stevia glycoside extracts have been generally recognized as safe since 2008 as per Food and Drug Administration (USA). The European Food Safety Authority also approved stevia additives in 2011. In November 2015, Food Safety and Standards Authority of India (FSSAI) allowed the usage of steviol glycosides as a sweetener in food products.
Overall, stevia is approved for consumption as a sweetener in over 130 countries.
