Chitosan Plus 90 capsules - Progressive labs.

Now with Vanson's Patented LipoSan Ultra.

Chitosan is a naturally occurring marine fiber extracted from shellfish shells. It has the unique capability of binding up to 12 times its own weight in dietary fat. LipoSan Ultra is 90% soluble in stomach acid in one minute...compared to an hour or more for regular chitosan products.

Each capsule contains:
LipoSan Ultra (high density chitosan marine fiber concentrate) 250 mg.
Citric Acid 75 mg.
Lipase (3000 units) 25 mg.

Other ingredients: gelatin, magnesium stearate.

Suggested Use:
As a dietary supplement, take 2 to 4 capsules with 8 ounces of water, three times daily, before or immediately after meals, or as directed by a doctor.

Chitosan-What does it do?
Like dietary fiber, chitosan is not digestible but may have beneficial effects on the gastrointestinal tract. Chitosan may reduce the absorption of bile acids or cholesterol, either of which may cause a lowering of blood cholesterol.1 This effect has been repeatedly demonstrated in animals, and a preliminary human study showed that 3 6 grams per day of chitosan taken for two weeks resulted in a 6% drop in cholesterol and a 10% increase in HDL (the good”) cholesterol.2 Another preliminary study 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 twelve weeks. This group also appeared to have improved kidney function and less severe anemia after chitosan treatment.3

Chitosan in large amounts given with vitamin C has been shown to reduce dietary fat absorption in animals fed a high-fat diet.4, 5, 6 Unfortunately, mineral and fat-soluble vitamin absorption is also reduced by feeding animals large amounts of chitosan.7 No studies have been done on the effects of chitosan on dietary fat absorption in humans.

Animal and preliminary human research suggests that chitosan may prevent the blood pressure-elevating effects of a high-salt meal, possibly by reducing the absorption of chloride. A small study showed that men taking 5 grams of chitosan with a meal high in salt resulted in no elevation in blood pressure, while the same meal without chitosan significantly elevated systolic blood pressure.8

Chitosan may also have an effect on bacteria in the intestines. A small human study found that taking 3 6 grams per day of chitosan for two weeks reduced indicators of putrefaction in the intestines,9 a change that might help prevent diseases, such as colon cancer.10

Where is it found?
Chitosan is a supplement commonly extracted from the shells of crustaceans, such as shrimp and crab. Chitosan has been used in connection with the following conditions (refer to the individual health concern for complete information):

• High blood pressure
• High cholesterol
• Kidney failure
