L-Carnitine has been the darling of stimulant-free fat loss supplements for over a decade. The problem is that, while good in theory, regular L-Carnitine never really delivered tangible results in research settings. This is due to the fact that free form L-Carnitine frankly has terrible bioavailability, and really only works if you’re chronically deficient in the essential nutrient. Blackstone Labs has transformed the prototypical L-Carnitine supplement into something elite in Carnitrim. Carnitrim is a stimulant-free energy and weight loss support supplement formulated to promote increased fat burning and weight loss as well as. Carnitrim harnesses the unique fat burning power of three highly bioavailable forms of carnitine, the biological “taxi” that shuttles fatty acids into the mitochondria where they can be utilized for fuel by the cell. It is ideal for any athlete looking to optimize performance, increase energy production, decrease soreness, and enhance recovery.
