What is Chitosan?
Chitosan is a dietary fiber derived from chitin. Chitin is an aminopolysaccharide (combination of sugar and protein) that comes from the shells of shellfish. Commercial chitosan is derived from the shells of shrimp and other sea crustaceans, including Pandalus borealis(fish). Chitosan is a naturally occurring substance that is chemically similar to cellulose which is a plant fiber. There are no calories in Chitosan. Like plant fibers, Chitosan possesses many of the some properties as fiber, however unlike plant fiber; it has the ability to significantly bind fat, acting like a "fat sponge" in the digestive tract.
What is the effective dosage of Chitosan supplementation?
The effective dosage is 2-6 grams per day - usually consumed in divided doses of about 1 gram with each meal.
What are the benefits of Chitosan supplementation?
Because Chitosan is a positively charged compound, it is able to attract and bind to fatty acids (which carry a negative charge). As such, chitosan can absorb up to 4-6 times its weight in fat (including cholesterol) and prevent that fat from being absorbed into the body. This means that for every gram of chitosan that you consume as a supplement, you'll prevent the absorption of about 4-6 grams of fat
• It traps the fat and prevents its absorption in the digestive tract. The fat binds to the Chitosan fiber and becomes a large mass, which the body cannot absorb.
• It reduces the absorption of bile acids or cholesterol.
• It promotes weight loss.
What are the side effects of Chitosan supplementation?
Some studies have proven chitosan causes gas, bloating, and diarrhea (due to fermentation of the fat in the large intestine).more long term and short term studies are required to established side effets.
• Because Chitosan is derived from shellfish; it should not be consumed by anyone with an allergy or sensitivity to any form of shellfish. Pregnant or nursing women should not use Chitosan.
• Chitosan supplements should not be consumed within two hours of taking the fat-soluble vitamins A, D, E and K, carotenoids (e.g., lycopene, lutein), flavonoids (e.g., genistein, quercetin, ipriflavone) or prescription medication.
Is Lecithin is good source of choline?
The bad news is that this (about Choline cotain) research was carried out more than 50 years ago - with fairly poor experimental designs. And lecithin is not such a great source of choline after all: The truth is that the choline in lecithin is found only in a chemical called phosphatidylcholine, and phosphatidylcholine makes up just 25 to 35 per cent of lecithin. In turn, only about 12 per cent of phosphatidylcholine is actually choline. 12 per cent of 35 per cent adds up to a paltry 4-per cent choline content for lecithin.
