Hey guys i am looking for a carb source to put into my shakes, something sugar-free or very low in sugar that is easy to digest and nutritious. I have used powdered oats but i think i am either gluten or avinin sensitive. Right now i am using brown rice flour but it seems to cause heartburn for me and stomach upset (this may not be the case for others, i have a sensitive stomach).
I was thinking, non-gmo organic potato starch (but i cannot find any), or sprouted brown rice flour. However nothing i can find in a powdered form or liquid for that matter fits the category of low in simple sugar, high carb with some nutritional perk, and easily digestible.
I may be asking for something that does not exist, or maybe you know of something. Thanks in advance.
