Health Notes

Chitosan

Chitosan
This nutrient has been used in connection with the following health goals
  • Reliable and relatively consistent scientific data showing a substantial health benefit.
  • Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
  • For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.

Our proprietary "Star-Rating" system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.

For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.

This supplement has been used in connection with the following health conditions:

Obesity
Dose: Refer to label instructions
Chitosan is a fiber-like substance that may reduce fat absorption. One study found it to be an effective weight-loss aid.(more)
High Cholesterol
Dose: Refer to label instructions
Chitosan is a fiber-like supplement that has been shown to lower cholesterol and raise HDL ("good") cholesterol).(more)
Kidney Failure
Dose: Refer to label instructions
(more)
Obesity
Dose: Refer to label instructionsChitosan is a fiber-like substance extracted from the shells of crustaceans such as shrimp and crab. Animal studies suggested that chitosan supplementation reduces fat absorption, but controlled human trials have found no impairment of fat absorption from supplementation with 2,700 mg of chitosan per day for seven days or 5,250 mg per day for four days.1, 2 A double-blind study found that people taking 1,500 mg of chitosan three times per day during a weight-loss program lost significantly more weight than did people taking a placebo with the same program.3 Similar benefits were seen in another double-blind study that used 3,000 mg of chitosan per day.4 Other studies using smaller amounts of chitosan have reported no effects on weight loss.5, 6, 7

High Cholesterol
Dose: Refer to label instructions

The fiber-like supplement chitosan appears to reduce the absorption of bile acids or cholesterol; either of these effects may cause a lowering of blood cholesterol. 1 This effect has been repeatedly demonstrated in animals, and a preliminary human study showed that 3 to 6 grams per day of chitosan taken for two weeks resulted in a 6% drop in cholesterol and a 10% increase in HDL ("good") cholesterol.2 Another preliminary trial showed a 43% lowering of total cholesterol in people being treated for kidney failure with dialysis who took 4 grams per day of chitosan for 12 weeks. These people also appeared to have improved kidney function and less severe anemia after chitosan treatment. 3 In a double-blind trial, however, administration of 2.4 grams of chitosan per day for three months to people with high cholesterol had no effect on their cholesterol levels. 4 Another study also found no cholesterol-lowering effect of chitosan when taken in amounts up to 6.75 grams per day for 8 weeks.5

Chitosan in large amounts, given with vitamin C, has been shown to reduce dietary fat absorption in animals fed a high-fat diet.6, 7, 8 However, the absorption of minerals and fat-soluble vitamins was also reduced by feeding animals large amounts of chitosan.9 In studies in humans, chitosan did not reduce the absorption of dietary fat.10, 11
