Liquid Supps Raspberry Ketones may help aid in fat loss by preventing fat storage. It does this by causing HSL (hormone-sensitive lipase) to enter fat cells. HSL is the enzyme that once inside the fat cell, slices apart fat molecules into various fatty acids in preparation for fat metabolism. In layman's terms, you cannot have maximum lipolysis without ample supplies of HSL inside the fat cell. WARNING Please watch what you are buying. There are a lot of liquids Raspberry Ketones out there that are deluded with multiple cheap ingredients: African Mango, Green Tea, Apple Cider and more.
