- Bios Life Slim™ is a proprietary fat loss formula. Its unique matrix of soluble and insoluble fiber, vitamins, minerals and anti-oxidants work together to improve our body's ability to regulate fat. br br As we age, our bodies slowly lose their ability to regulate fat. As a result, our bodies end up storing excess fat. Bios Life Slim™ not only helps prevent our bodies from storing excess fat, but it also allows existing fat to be burned away - naturally...no jitters, no starving, no stimulants. br br The most noticeable changes you can expect at first are an increase in energy and a reduction in appetite and cravings.
