The Role of Prebiotic Inulin

The Role of Prebiotic Inulin

Each serving of IsoNatural includes inulin, a prebiotic fiber derived from chicory root. A randomized controlled trial by Guess et al. found that 30 g/day of inulin supplementation significantly reduced prospective food consumption (a marker of improved satiety) in adults with prediabetes over 18 weeks. The inulin group also experienced a 2.3% reduction in body weight during the weight-maintenance phase (weeks 9–18) and a 9.6% reduction in intrahepatocellular liver fat after just 9 weeks, compared with −0.5% in the placebo group.

FAQ

IsoNatural is produced through cross-flow ultrafiltration and ion filtration, preserving native protein fractions. It contains no artificial sweeteners, colors, or flavors and includes prebiotic inulin for digestive support—distinguishing it from standard whey isolates that rely on synthetic sweetening systems.

Whey protein isolate is naturally very low in lactose due to the filtration process used to remove fat and carbohydrates. ALLMAX IsoNatural is 99% lactose-free, making it a suitable option for most individuals with lactose sensitivity.

Yes. IsoNatural is 99% lactose-free. Many dairy sensitivities stem from casein rather than whey, and because IsoNatural contains no casein protein, it is generally well tolerated by lactose-sensitive individuals.

Yes. IsoNatural is sweetened with stevia (Stevia rebaudiana leaf extract—no sucralose, no acesulfame potassium, no artificial sweeteners).

Inulin is a prebiotic fiber from chicory root. It supports healthy intestinal microflora, may improve satiety, and has been associated with modest reductions in body fat in clinical research.
