Losing weight can be extremely difficult, which is why many people turn to vitamin B12 injections to aid their efforts. The injections, however, require a doctor's prescription and must be administered at a medical office, making them harder to get ahold of than a Michael Jordan rookie card slathered in grease. That's why Super MIC B12+'s team came up with the Super MIC-Lipotropic B12 oral shot, a metabolism-boosting lipotropic injection in liquid form. The sweet-tasting liquid contains everything from chromium, which may help suppress appetite, to carnitine, which may boost metabolism. Because it's in liquid form, it also helps the body absorb as much as the nutrients and super foods from the oral shot as possible.
