Artificial sweeteners are a sticky topic. Of all of the sweeteners, we decided that Sucralose is among the safest and best tasting. The only other option would be to use some real form of sugar and we are very against consuming sugary beverages. Our take on it is that you will have much more acute adverse effects from sugar (diabetes/insulin resistance) than from sucralose. Another thing to factor in is that we do not use that much in our formula anyway.
