Chitosan is gaining popularity as an alternative method in weight loss. With more and more people using it, especially women, some concerns are brought up regarding its safety and effectiveness. Whether it can be used as a diet tool still remains a controversy waiting for answers. 

Basically, chitosan is a substance found in the shells of crustaceans, like crabs, lobsters and shrimp. It is extracted and taken in the form of a supplement with meals, believing that it encourages weight loss by binding to fat molecules in the digestive tract, preventing the body from absorbing the fat in the end.

Several studies have reported that Chitosan really does work for weight loss, while others have reported that it doesn’t.  No matter what the reports have revealed or suggested, it is best to look at the chitosan warnings.  After all, there is nothing wrong with being skeptical. 

Here are some chitosan warnings you may encounter when you consider chitosan.  These chitosan warnings are really worth noting:

- Although chitosan is quite safe, there is a possibility, in theory at least, that it could block the absorption of the fat-soluble vitamins, such as Vitamins A, D, E and K.  Also, chitosan may block the absorption of the essential fatty acids, like omega 3 and 6.  Therefore, it is necessary to be sure that you take vitamin supplements at least an hour or so before taking the chitosan. 

- Another notable chitosan warning is never take chitosan if you have an allergy to shellfish.  Just note that chitosan is derived from shellfish. 

- Chitosan doesn’t get absorbed into the bloodstream.  This simply means that it is largely free of the side effects that so many people experience with a number of prescription and nonprescription weight loss supplements and medications. 

- Chitosan is not good for pregnant women, so avoid taking it when you’re pregnant.  Also, when you are nursing or taking any medication, consult your health care professional first before taking any product that contains chitosan. 

- Take chitosan with large amounts of fluid.  The reason for this chitosan warning is the fact that without drinking enough liquid, the product may cause constipation.  And, if intestinal discomfort or constipation occurs, discontinue use. 

- Because no extensive safety studies have been done to back up the claimed benefits of chitosan, people must be careful, and must seek guidance from a health care professional before taking any chitosan product. 

Aside from those above mentioned chitosan warnings, there are other factors that must be considered before buying chitosan-based products.  First of those is the fact that the composition of chitin may vary depending on the seawater, the animal from which it is taken, and the time of year.  Note that there is no pure form that can be counted on. 

Another chitosan warning is that the Federal Trade Commission (FTC) won an $8.3 million judgment against a company violating federal consumer protection laws with false claims concerning chitin.  The FTC lawsuit is the first of several additional suits for false claims regarding chitosan. 

These facts are presented to give you precautionary measure when taking chitosan. It is better to be on the safe side than to be sorry. A full knowledge of chitosan products is vital if you are planning to use it. Don’t follow the majority, since what may work for them may not work for you. Better to consult an expert if you are in doubt about chitosan.
