Xanthan Gum... is this really a good product if it has sugar ?

I see lots of people who are on  low carb diets that use this in tons of recipes but from the research i have done and reading on it i think i might just not bother with it. when you wiki this one section says: :Xanthan gum is a "highly efficient laxative," according to a study that fed 15 g/day for 10 days to 18 normal volunteers. This is not a dosage that would be encountered in normal consumption of foodstuffs. This study set out to examine the use of xanthan gum as a laxative. As described above, xanthan gum binds water very efficiently, which significantly aids passing stools.^[13] Some people react to much smaller amounts of xanthan gum with symptoms of intestinal bloating and diarrhea.::::: another one says::::

 xanthan gum seems to be capable of (in adults) is causing some digestive distress in those who are susceptible by increasing stool bulk, water content, and sugar content. But as I just mentioned, those with severe allergies should also be careful . Xanthan gum is a largely indigestible polysaccharide that is produced by bacteria called Xanthomonas Camestris. (1) Manufacturers place the bacteria in a growth medium that contains sugars and other nutrients, and the resulting product of bacterial fermentation is purified, dried, powdered, and sold as xanthan gum. (Makes you wonder who first thought to put it in food, doesn’t it?)     so in conclusion it's gonna make you poop and it has sugar in it then why are people using it? you are replacing one sugar with another
