Skinnybik do not contain laxative sweeteners like mannitol, maltitol, sorbitol or xylitol found in other low carb/sugar free products.  Polydextrose fibre may have a laxative effect if you consume 15 bikkies or more in one day!  As for the bloating, lupin is a legume which may cause bloating in some people, especially in those with IBS.  Diarrhoea and bloating has been rarely reported by my patients over the last 10 years!
