Some time ago, we changed one of the ingredients of our flavored protein powders....we replaced the sucralose with stevia. Both items have a higher sugar taste than just plain sugar; however, stevia is the only "natural" option as it's made from a plant native to South America. Sucralose's downside is that your body can absorb the chlorine atoms, which can attack the good bacteria in your body. Few people noticed the difference because the flavor isn't as sweet as before, but no major complaints. A lot of folks even praised the change. We're happy because this falls in line with our "pure" ingredients objective. We hope you all enjoy?
