Name and Basic Overview

NOW Foods Chitosan is a dietary supplement primarily marketed for weight management and cholesterol support. It contains 500 mg of chitosan per capsule, a polysaccharide derived from the shells of crustaceans, and is enhanced with chromium. Chitosan is naturally sourced from marine crustaceans, while chromium is a mineral found in various foods and supplements. People commonly seek chitosan for its potential to bind dietary fats and cholesterol, aiding in weight management and maintaining cholesterol levels within a healthy range.

Historical Background / Traditional Use

Chitosan has been used in various applications, including water purification and as a food preservative, due to its ability to bind with fats and other substances. While not traditionally used in ancient medicine, its fat-binding properties have made it a popular supplement in modern weight management practices.

Composition and Active Components

The primary active component in this supplement is chitosan, a polysaccharide that can bind to fats and cholesterol in the digestive tract, potentially reducing their absorption. Chromium, included in the form of chromium nicotinate glycinate, is essential for normal glucose metabolism and may help regulate blood sugar levels.

Research and Evidence Base

Research on chitosan's efficacy in weight management and cholesterol support is mixed. Some studies suggest that chitosan can modestly reduce body weight and cholesterol levels, but results are not universally conclusive. A clinical study on LipoSan ULTRA®, the form of chitosan used in this supplement, indicated it might bind more fat than conventional chitosan, potentially enhancing its effectiveness in weight management. Chromium's role in glucose metabolism is well-documented, with evidence supporting its use in maintaining normal blood sugar levels, although its impact on weight loss is less clear. Overall, while some evidence supports the use of chitosan and chromium for weight management and cholesterol support, further research is needed to confirm these benefits conclusively.

Potential Health Benefits

• Weight Management: Chitosan is often marketed for its ability to support weight management. It is a polysaccharide that can bind to dietary fats in the digestive tract, potentially reducing fat absorption and promoting weight loss. The inclusion of LipoSan ULTRA® in this product claims to enhance this fat-binding capacity significantly.
• Supports Cholesterol Levels: Chitosan may help maintain cholesterol levels already within a healthy range by binding to cholesterol in the digestive system, thus reducing its absorption.
• Chromium for Glucose Metabolism: Chromium is an essential mineral that plays a role in normal glucose metabolism, which can be beneficial for maintaining stable blood sugar levels.

Safety, Side Effects, and Precautions

• Gastrointestinal Effects: Some users may experience gastrointestinal upset, such as bloating, gas, or constipation, due to the fat-binding action of chitosan.
• Allergic Reactions: Individuals with shellfish allergies should avoid this supplement, as chitosan is derived from crustacean shells.
• Specific Populations: Pregnant or breastfeeding women, children, and individuals with specific health conditions should consult a healthcare provider before using this supplement.
• Nutrient Absorption: There is a potential for chitosan to interfere with the absorption of fat-soluble vitamins and other nutrients, so it may be advisable to take it at a different time than other supplements or medications.

Summary and Takeaway

Main Benefits: Supports weight management and cholesterol levels; includes chromium for glucose metabolism.

Caveats: Potential gastrointestinal side effects; not suitable for those with shellfish allergies; may affect nutrient absorption.

Potential Risks: Allergic reactions and nutrient absorption interference.

Worth Trying?: This supplement may be beneficial for those looking to support weight management and cholesterol levels, provided they do not have shellfish allergies and are aware of potential nutrient absorption issues.

Rating Among Similar Supplements: 7/10. The inclusion of LipoSan ULTRA® and chromium offers a unique formulation, but the effectiveness of chitosan for weight loss is still debated.

Rating Based on Research: 6/10. While there is some promising research, more comprehensive studies are needed to fully validate the weight management claims of chitosan.
