This is your guide to available sweeteners
Allulose - This sweetener is about 70% the sweetness of sugar. There are some claims of additional health benefits. It is made from corn, so ideally you want to find either a non-gmo version or even better an organic version. There are some name brands like Sweet Leaf's Indulge that use a mix of sweeteners such as adding stevia extract and monk fruit extract to make it a 1:1 sugar replacement, but they are not necessarily non-gmo or organic, but are easier to use to convert your existing recipes.
