If it says pure Maple syrup, then it does not contain any other additives to it. I did my first Master Cleanse with Grade A Maple syrup from Walmart and did just fine. It took awhile to find the Grade B in this rural area and I wanted to get started. Frankly, I have never noticed any differences. I've done more than one cleanse using evaporated cane syrup because I like the flavor better and it contains pretty much the same level of minerals as the Maple syrup, and is not nearly as processed. Master Cleanse needs to be done with a sweetened drink. Having those carbs is one reason this fast is so much easier than water only.
