The research I did after my T2 diagnosis suggested that erythritol and stevia - either individually or in combination are the best alternative sweeteners for me. I've now used them for over nine years and I've never had any issues with them raising my glucose levels. I prefer to use the term "alternative" as they occur naturally rather than being artificially produced. Be careful though if you opt to use stevia as it's often bulked out with other stuff due to its extreme sweetness.
