Chitosan Fat Blocker Side Effects

According to the National Institute of Health (NIH), chitosan is promoted in the United States and other countries as a dietary aid to curb the absorption of fat. Chitosan is a primary ingredient in various over-the-counter supplements. This purported fat blocker comes from chitin, which is a polymer (a natural or synthetic compound made of many chemically bonded smaller identical molecules). Chitin is derived in the bones of crab, crayfish and squid.
In addition to weight loss, chitoson is also touted as a means of treating anemia (depleted iron in the blood), gum infections, insomnia and improving the immune system. There are also claims that it can help tissue heal after plastic surgery. There are several side effects linked to chitosan.

Allergic Reactions

There are a number of allergic reactions associated with the use of chitosan particularly among people who are sensitive to shellfish. Possible effects include difficulty breathing and/or tightness in the chest or throat. Some individuals may break out in hives, develop a rash or experience a swelling of the skin.
If you suspect you are having an allergic reaction to chitoson, stop taking the supplement at once and consult your doctor.

Side Effects

Chitosan may slow the absorption of minerals and fat-soluble vitamins. It should not be used by people who suffer from intestinal malabsorption syndrome (the inability to absorb nutrients through the gut lining). Chitosan may cause headaches in some individuals.

Precautions

If you plan to take chitosan, inform your doctor of any current health issues you may have (heart disease, high blood pressure). Also provide a list of medicines you are currently taking and whether you are allergic to any prescription and over-the-counter drugs or dietary aids. Tell your doctor if you are pregnant, intend on becoming pregnant or are currently breastfeeding.
If you do decide to take chitosan, be sure to adhere to the directions on the label. If you develop any side effects, discontinue the use of chitosan immediately and speak with your doctor.
