Fibersol® (Digestion-Resistant Maltodextrin — ADM/Matsutani)

Evidence Level
Moderate
1 Clinical Trial
3 Documented Benefits
3/5 Evidence Score

Fibersol® is a digestion-resistant maltodextrin, a soluble prebiotic fiber made from cornstarch, co-developed by ADM and Matsutani. It dissolves clear and tasteless, making it easy to add to foods and drinks, and is studied for supporting satiety, healthy blood sugar, and regularity.

Studied Dose Acute satiety and glycemic trials used 6 to 10 g per dose; the visceral-fat trials used 15 to 27 g per day in three divided doses.
Active Compound Digestion-resistant maltodextrin, a soluble dietary fiber that resists digestion and is partly fermented in the colon.

Benefits

Satiety and appetite

In clinical research, the soluble fiber reduced hunger and increased fullness, supporting appetite control and weight management.

Supported by Trial 1

Healthy blood sugar

Fibersol can blunt the rise in blood sugar and insulin after meals, supporting steadier post-meal glucose.

Supported by Trial 1

Regularity and gut health

As a fermentable soluble fiber, it is fermented in the colon to short-chain fatty acids such as butyrate and can raise beneficial bacteria like bifidobacteria. Effects on stool frequency in healthy adults are modest.

Supported by Trial 1

Mechanism of action

1

Soluble fiber bulking

The resistant maltodextrin adds soluble bulk that slows gastric emptying and nutrient absorption, supporting fullness and steadier glucose.

2

Colonic fermentation

Part of the fiber is fermented into short-chain fatty acids that nourish the colon and support a healthy microbiome.

Clinical trials

Study of the soluble dietary fiber Fibersol-2 on hunger and satiety. (Ye et al. 2015, Nutrition Research)

Adults.

The soluble fiber decreased hunger and increased satiety versus control, supporting its appetite and weight-management uses.

Side effects and drug interactions

Common Potential side effects

Generally well-tolerated — well tolerated even at higher fiber intakes.
Mild gas or bloating can occur as intake rises.
Increase the dose gradually.

Important Drug interactions

Diabetes medication — fiber may affect blood sugar; monitor.
May slow absorption of some medications; separate dosing if advised.
Tell your doctor if you have a digestive condition.

Nutr Res. 2015;35(5):393-400..PubMedUsed to support: Randomized double-blind placebo-controlled crossover trial in 19 healthy adults: 10 g of Fibersol-2 taken with a meal delayed hunger and increased fullness for 1.5 to 2 hours and raised the satiety hormones peptide YY and GLP-1, while 5 g had no effect. It measured appetite ratings and hormones, not body weight. One author is employed by the manufacturer.
