Isomalt
Also known as: isomalt, palatinit, hydrogenated isomaltulose, sugar alcohol, polyol
Effective Dosage
No established dose from provided studies
What the Science Says
Isomalt is a sugar alcohol (polyol) derived from sucrose, commonly used as a low-calorie sweetener and food ingredient. Because it is only partially digested and absorbed in the gut, it produces a much smaller rise in blood glucose and insulin compared to regular sugar, making it a popular ingredient in diabetic-friendly foods. The provided studies primarily used isomalt as a placebo ingredient or excipient in pharmaceutical formulations, and one review notes that polyols like isomalt may support blood sugar management in diabetic diets.
What It Doesn't Do
Not proven to directly treat or manage diabetes on its own. No evidence from these studies that it improves hormones, reduces inflammation, or boosts gut health by itself. Don't confuse its role as a placebo ingredient in studies with it being an active therapeutic agent. It is not a probiotic or prebiotic.

Absorption & Bioavailability
Poor — isomalt is only partially absorbed in the small intestine; the remainder is fermented by gut bacteria in the colon. This is why it has a low glycemic index but can cause digestive side effects at higher doses.
Red Flags to Watch For
- Can cause bloating, gas, and diarrhea at higher doses — FDA guidelines warn against excessive consumption
- Most studies in this dataset used isomalt as a placebo or inactive excipient, not as an active ingredient being tested for health benefits
- Marketed in 242 supplement products despite very limited direct clinical evidence for health benefits
- Laxative effect possible at doses above ~20-30 g/day; individual tolerance varies
