Liposan Ultra
Also known as: Chitosan, LipoSan Ultra™, Chitosan supplement
Overview
Chitosan is a polysaccharide derived from chitin, found in crustacean exoskeletons and fungal cell walls. It's primarily used as a dietary supplement to aid weight loss and reduce fat absorption. LipoSan Ultra™ is a rapidly soluble form of chitosan. Research suggests chitosan may contribute to modest weight loss by binding to dietary fats in the gastrointestinal tract, reducing their absorption. It is generally considered safe, but its efficacy can vary. Studies indicate that chitosan is not absorbed into the bloodstream, acting locally within the digestive system. The quality of available evidence varies, but includes randomized controlled trials and systematic reviews. While some studies show promising results, others suggest the clinical significance may be limited. Further research is needed to fully understand its effects and optimal usage.
Benefits
Chitosan, particularly LipoSan Ultra™, has demonstrated potential benefits for weight management. A randomized, double-blind, placebo-controlled trial showed that subjects taking LipoSan Ultra™ experienced a statistically significant mean weight loss of 1 kg and a 1% reduction in BMI over an 8-week period, compared to a mean weight gain of 1.5 kg in the placebo group. The treatment group also had a higher percentage of subjects who lost weight (63% vs 17% in the placebo group). Additionally, the same study reported a significant decrease in waist-to-hip ratios in the treatment group compared to baseline. These benefits were observed in overweight and mildly obese individuals. While some subjects reported increased stool bulkiness and ease in bowel elimination, these results were not statistically significant.
How it works
Chitosan's primary mechanism of action involves binding to dietary fats within the gastrointestinal tract. This binding action reduces the amount of fat absorbed by the body, subsequently increasing fecal fat excretion. Chitosan interacts with the digestive system by forming a gel-like substance that encapsulates fats, preventing their absorption into the bloodstream. Since chitosan is not absorbed itself, it acts locally within the gut. While the exact molecular targets are not fully defined, it is known to interact with dietary fats and bile acids, contributing to its fat-binding capabilities.
Side effects
Chitosan is generally considered safe for consumption when taken as directed. Common side effects are rare, with studies reporting no significant adverse effects in most participants. Some individuals may experience mild gastrointestinal changes, such as increased stool bulkiness or changes in bowel elimination, although these effects are typically not statistically significant. There are no known significant drug interactions reported in the literature. However, safety and efficacy in special populations, such as pregnant women, children, and individuals with severe gastrointestinal disorders, have not been extensively studied. As with any supplement, it is advisable to consult with a healthcare provider before starting chitosan, especially if you have pre-existing health conditions or are taking other medications.
Dosage
The minimum effective dose of Chitosan, specifically LipoSan Ultra™, is 3 grams per day, divided into two doses of 1.5 grams each. These doses should be taken just prior to the two largest meals of the day to maximize the binding of dietary fats. While there is no established maximum safe dose, studies have used 3 grams per day without significant adverse effects. The rapidly soluble form of chitosan (LipoSan Ultra™) is often recommended for better efficacy. Since chitosan is not absorbed, its effectiveness is not influenced by absorption factors, and no specific cofactors are required for its action. It's important to adhere to recommended dosages and consult with a healthcare professional for personalized advice.
FAQs
Is chitosan safe to use?
Chitosan is generally safe when used as directed, with no significant side effects reported in most studies. However, consult a healthcare provider if you have pre-existing conditions.
When should I take chitosan?
Take chitosan just before meals to maximize its fat-binding effect. A typical regimen involves taking it prior to the two largest meals of the day.
What results can I expect from taking chitosan?
Users may experience modest weight loss and a reduction in BMI over an 8-week period, along with potential improvements in gastrointestinal health. Results can vary.
Is chitosan a replacement for a healthy diet and exercise?
No, chitosan is not a magic bullet for weight loss. It should be used in conjunction with a healthy diet and lifestyle for optimal results.

- https://www.liposan.com/media/documents/Liposan_fullstudy.pdf – This randomized, double-blind, placebo-controlled trial examined the effects of LipoSan Ultra™ on overweight and mildly obese individuals. The study found that subjects taking LipoSan Ultra™ experienced a significant mean weight loss of 1 kg and a 1% reduction in BMI over an 8-week period compared to the placebo group. The treatment group also showed a significant decrease in waist-to-hip ratios compared to baseline.
- https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD003892.pub3/references – This Cochrane systematic review analyzed various studies focusing on overweight and obese individuals to determine the effects of chitosan on body weight. The review concluded that chitosan may result in a small, statistically significant reduction in body weight, but the clinical significance is uncertain due to heterogeneity among the included studies. The quality of evidence varied among the included studies.
- https://skemman.is/bitstream/1946/42013/1/MSc_FINAL.pdf – This randomized controlled trial investigated the effect of LipoSan Ultra on athletic performance and mental health in 64 Icelandic athletes. The study found no significant benefits for athletic performance or mental health. This suggests that LipoSan Ultra is not effective for enhancing athletic performance or improving mental well-being.
