XLS - Medical Fat Binder is for the Treatment and Prevention of Excess Weight and General Weight Management XLS - Medical Fat Binder in pack size 60 tablets is an effective weight management tool that helps to reduce more weight than dieting and exercise alone. How XLS-Medical Fat Binder works? XLS - Medical Fat Binder uses Circadian technology to facilitate a sequential release fo first Litramine and secondly fat-soluble vitamins. Firstly, the fibre complex Litramine binds readily with fat from food and becomes a large fat-fibre complex. As the fat-fibre complex is too large to be absorbed in the small intestine, it is eventually excreted from the body. After the fat binding phase, the essential fat-soluble vitamins A, D and E are released and absorbed in the body. This optimizes the availability of fat-soluble vitamins for absorption by the body. Apart from binding fat, XLS - Medical Fat Binder also helps to manage food cravings and appetite.
