With the ability to break down fat while simultaneously causing an increase in metabolic rate, Advantra Z has proven effective for burning calories, reducing weight, increasing lean muscle mass to total body mass, and suppressing appetite. It is the only patented Citrus aurantium, bitter orange or citrus extract product for weight loss and physical performance on the market today. Advantra Z contains a rare combination of five naturally occurring components that, because they are less likely to cross into the central nervous system, are available to focus their activity where they are most wanted, on fat cells.
