Stevia. Whether or not you qualify that as "artificial" is up to you.
This is a good basic information site based on the Q&A, but just as a side note, "Stevia.com" is usually not the most reliable place to get information on Stevia, just as "_____.com" is not the best place to get information on whatever substance ______ is. It will ALWAYS be biased.Personally, I do not qualify stevia as "artificial" as it's made from a plant... but that's just me
(for more info, i found this link which you can read... or not .. your choice.. hehe : )
My dietary needs over the last 6 yrs have led me on many paths to find protein powders & RTDs and like you, I try to stay away from the chemicals and stick with natural/organic products.
