The Fiber Science of Chitosan

LipoSan Fibers & Vitamin C is a dietary supplement combining bioactive chitosan—a natural fiber derived from cold-water shrimp shells—with Vitamin C. It’s designed to support digestion, weight management, and general well-being. Users are encouraged to take it before or with meals, ideally paired with a glass of water. The Vitamin C also aids collagen production, energy metabolism, immune function, and offers antioxidant protection.  

Chitosan is a natural amino-polysaccharide, chemically similar to cellulose but with a positively charged (cationic) structure, unlike most dietary fibers. In the acidic environment of the stomach, it becomes soluble and viscous—behaving like a soluble fiber.

For this dietary supplement, we use a special blend of chitosan that we manufacture in-house, called LipoSan Ultra®. What sets it apart is its optimized physical properties thanks to a patented, eco-friendly processing method: high density, molecular weight, and exceptional acid solubility. These enhancements enable rapid dissolution (within 3–5 minutes), creating a gel-like emulsion with dietary fats. This gel traps fat, preventing its absorption in the small intestine and allowing it to pass through and exit during bowel movements.  

Lab tests simulating digestion show that LipoSan Ultra® binds notably more triglycerides than standard chitosan—and much more efficiently within a short time frame. Clinical findings support this too: users taking 3 g/day of LipoSan Ultra® experienced measurable weight loss compared to placebo under a non-restrictive diet.  

LipoSan Ultra® Health Benefits 

1. Weight Management & Fat Binding 

Thanks to its rapid solubility and high fat-binding capacity, LipoSan Ultra® helps reduce calorie uptake from fats—making it a natural, low-side-effect alternative to heavy-weight drugs. In clinical trials, supplementation led to significant reductions in both body weight and BMI.  

2. Cholesterol & Blood Pressure Support 

A daily dose of around 3 g chitosan has been approved by the European Food Safety Authority (EFSA) to maintain normal blood LDL-cholesterol levels. Also, supporting weight and fat management indirectly benefits blood pressure regulation.  

3. Prebiotic & Gut Health Effects 

LipoSan Ultra® isn’t digested but is fermented by colonic bacteria. This fermentation produces metabolites—like short-chain fatty acids (SCFAs)—that support gut health and overall metabolic function.  

In vitro and early human studies have shown that chitosan may shift gut microbiota, boosting beneficial bacteria like Bifidobacterium, increasing SCFA production (e.g., butyrate, propionate), and promoting healthier colonic conditions. A 2025 randomized, placebo-controlled trial in Icelandic women (3 g/day for 12 weeks) confirmed bacterial shifts in the gut microbiome (for example, increased Bifidobacterium and others), demonstrating chitosan’s prebiotic capacity without negative health effects.
