MetaFixer may support a healthy weight management program by helping to increase your body's metabolic rate without causing any stimulant-associated side effects. While dieting helps with weight loss, it ultimately slows down your metabolism, affecting fat-burning. Supplementation may help raise your metabolism, or the rate at which your body burns calories. As we get older, our metabolism starts to slow down, mainly thanks to the loss of lean muscle tissue. This professional, gluten-free dietary supplement contains several natural ingredients -- including naringin, green tea, fucoxanthin, bitter orange and hesperidin -- to support healthy weight management. Naringin, for example, is a phytochemical derived from citrus grandis osbeck, or buntan pumelo, which resemble grapefruit but are a species in their own right.
