Raspberry Ketone Fusion is a natural diet formula that is infused with Razberri-K and EGCG Green Tea Extract. These ingredients support energy and boost metabolism. Razberi-K (4-(4-hydroxyphenyl) butan-2-one) alters fat metabolism in two important ways. First, Razberi-K prevents lipid absorption. Secondly, it processes existing bodily fat by increasing levels of norepinephrine, a lipid burning hormone. With this dual action, Razberi-K burns fat and helps keeps it off! Razberi-K is a novel ketone found in fresh red raspberries. Raspberries are known for their healthy, complex bioactive constituents. Traditionally, raspberries have been used to treat many different ailments and conditions. More recently they have been utilized as an effective aid in weight loss. Raspberries contain a singular ketone isolated in a form given the name: Razberi-K. This unique ketone has the ability to boost body fat reduction and decrease body fat absorption, as mentioned above. It boosts metabolic functionality, while decreasing the production of free radicals in your system. It also operates like a ?fat blocker? – coating dietary lipids in the stomach prior to digestion. Its mucogenic final form is produced through bonds with the fat chemical matrix, thus blocking large percentages of fat from being absorbed into the blood stream. These fat derivatives can then pass through the digestive organs in the form of colonic waste – and not be added to the body’s internal fat load.
