Litesse Fiber
Also known as: Litesse Fiber, Litesse, polydextrose, Polydextrose
Overview
Polydextrose, marketed as Litesse Fiber, is a synthetic, non-digestible carbohydrate classified as a soluble dietary fiber and prebiotic. It is manufactured from glucose polymers and is not naturally occurring. Its primary uses include increasing dietary fiber intake, improving digestive health, modulating appetite, and supporting weight management. Polydextrose is a low-calorie, soluble fiber with prebiotic properties, meaning it promotes the growth of beneficial gut bacteria and the production of short-chain fatty acids (SCFAs). Research on polydextrose is extensive, with multiple randomized controlled trials (RCTs) and meta-analyses supporting its effects on appetite reduction and gut microbiota modulation. It is generally recognized as safe (GRAS) and well-tolerated at recommended dosages.
Benefits
Polydextrose offers several evidence-based benefits. Its primary effect is appetite reduction, with meta-analyses showing it significantly reduces subjective feelings of desire to eat during the satiation period and can decrease voluntary energy intake at subsequent meals. This effect is dose-dependent, typically observed with 4-12 g/day, and is supported by statistically significant effect sizes and confidence intervals. Another key benefit is gut microbiota modulation; clinical studies demonstrate that 4-12 g/day of polydextrose increases fecal bifidobacteria and lactobacilli counts, reduces fecal pH, and boosts butyrate production after four weeks. These changes contribute to improved digestive health. Secondary benefits include potential lipid metabolism improvements, as suggested by animal models showing altered gut microbiota composition and reduced triglycerides and cholesterol. Polydextrose is particularly beneficial for healthy adults and overweight individuals seeking appetite control and weight management. The appetite suppression effects are statistically significant with moderate effect sizes, leading to clinically relevant reductions in calorie intake. Acute appetite effects are observed post-meal, while microbiota changes typically manifest after four weeks of consistent daily intake.
How it works
Polydextrose exerts its effects primarily through fermentation by colonic bacteria. As a non-digestible carbohydrate, it passes through the small intestine unabsorbed and reaches the colon, where it is fermented. This fermentation process produces short-chain fatty acids (SCFAs) such as acetate, propionate, and butyrate. These SCFAs play a crucial role in satiety signaling by influencing the release of gut hormones like Glucagon-like peptide-1 (GLP-1) and Peptide YY (PYY). These hormones interact with the gut-brain axis, thereby influencing central appetite regulation. Polydextrose also directly modulates the gut microbiota composition, promoting the growth of beneficial bacteria like bifidobacteria and lactobacilli, which further contributes to SCFA production and overall gut health. Its interaction with the body is localized to the gastrointestinal tract, specifically the colon, where it acts as a prebiotic substrate.
Side effects
Polydextrose is generally recognized as safe (GRAS) and exhibits a good safety profile, particularly at doses up to 12 g/day. The most common side effects, occurring in more than 5% of individuals, are mild gastrointestinal symptoms. These include bloating, flatulence, and mild diarrhea, which are more likely to occur at higher dosages or when first initiating supplementation as the gut adjusts to increased fiber intake. Uncommon side effects, reported in 1-5% of users, include rare instances of general abdominal discomfort. Serious adverse events have not been reported in clinical trials. There are no significant drug interactions known for polydextrose. Contraindications have not been formally established, but caution is advised for individuals with severe pre-existing gastrointestinal disorders. Data on its use in pregnant or lactating women is limited, though it is generally considered safe for healthy adults. Users are advised to start with lower doses and gradually increase to the recommended range to minimize potential gastrointestinal discomfort.
Dosage
The minimum effective dose for observing appetite modulation effects with polydextrose is approximately 4 grams per day. The optimal dosage range for both appetite and microbiota benefits is between 4 to 12 grams per day. Benefits, particularly for appetite suppression and gut microbiota modulation, are dose-dependent within this range. The maximum safe dose, as demonstrated in clinical studies, is up to 12 grams per day; exceeding this amount may increase the likelihood and severity of gastrointestinal side effects such as bloating and flatulence. For optimal appetite suppression, polydextrose should be consumed with meals. It is available in various forms, including powder and as an ingredient incorporated into food products. Polydextrose is not absorbed in the upper gastrointestinal tract but is fermented in the colon, which is key to its mechanism of action. No specific cofactors are required for its efficacy.
FAQs
Is Litesse fiber safe for daily use?
Yes, clinical trials have shown that polydextrose (Litesse fiber) is safe and well-tolerated for daily use at doses up to 12 grams per day.
How quickly does it reduce appetite?
Effects on the desire to eat are typically observed acutely during the satiation period, meaning shortly after consumption with a meal.
Can it help with weight loss?
By reducing calorie intake through its appetite-suppressing effects, polydextrose may support weight management efforts and contribute to weight loss.
Does it cause digestive discomfort?
Mild gastrointestinal symptoms like bloating or gas can occur, especially when starting supplementation or at higher doses, but these are usually transient.
Is it a natural fiber?
No, polydextrose is a synthetic soluble fiber, manufactured from glucose polymers, rather than being naturally occurring.

- https://pmc.ncbi.nlm.nih.gov/articles/PMC4728658/ – This systematic review and meta-analysis by Ibarra et al. (2016) analyzed multiple randomized controlled trials on polydextrose's effect on subjective appetite ratings. It found a significant reduction in the desire to eat during satiation with a moderate effect size, supporting polydextrose's role in appetite suppression. The study was of high quality, addressing variability in study designs through a random effects model.

(2000), describes a clinical study with 120 healthy adults. It demonstrated that daily consumption of 4, 8, or 12 g of Litesse for 4 weeks led to dose-dependent increases in beneficial gut bacteria (bifidobacteria and lactobacilli), decreased fecal pH, and increased butyrate production, highlighting its prebiotic effects.
