Rasva is a nonprescription pill product that is marketed as being a fat binder. This weight loss supplement is manufactured by Holland and Barrett. It was created in Europe, where its official website claims that it is clinically tested. This site is designed in a way that suggests that it is a safer alternative to other products that make similar weight loss claims.
Overall, the claims regarding Rasva are that it helps to decrease the fat absorption from food that is consumed, and the product helps to reduce cholesterol absorption. These goals are achieved by taking the pills while following a diet that focuses on nutrition, a proper balance of fats and carbohydrates, as well as vitamins and minerals. It also recommends physical activity to help to break down deposits of fat, despite the fact that it can increase caloric consumption.
There is only one active ingredient in Rasva. It is a trademarked complex that is based on a number of ingredients, but that is primarily chitosan. The other ingredients other than chitosan are not active, as they are simply to compose the capsule itself. This ingredient is commonly found in fat blocking formulas and although it has a moderately good reputation for being able to block the absorption of some amounts of fat, according to medical studies, its actual level of effectiveness is not proven. There is no firm clinical or scientific evidence that this ingredient actually works.
Equally, though, there are many positive reviews available for products containing chitosan for this purpose. They claim that the substance binds fat into a fibrous compound that the body is not capable of absorbing. This causes it to pass through the body and be expelled with waste so that it will not be added to the stored fat in the body.
Chitosan is a type of polysaccharide that is made up of d-glucosamine, which is a carbohydrate that occurs naturally in the shells of shrimp and crab. However, there is a variant of chitosan that is also produced by a fungus that is called aspergillus niger mycelium – a natural type of mold, which is the same form that is found to be toxic in damp houses and those that have been flooded. It is this second form that is used within the Rasva ingredient so that vegetarians and people who are sensitive to seafood will be able to take it. This product contains 500 mg of the substance.
