Stevia comes from a South American plant that produces incredibly sweet leaves. Said to be 200 times sweeter than sugar, but no calories or carbohydrates and no effect on blood sugar.
Not only does it help make things taste sweeter it might also help your skin. Stevia contains retinoic acid which prevents the breakdown of collagen and elastin in the skin. This breakdown is what is responsible for wrinkles as we age.
It also has antibacterial properties that can prevent cavities and tooth decay.
