Turn Fat into Fuel: Optimize your body’s ability to convert fat into energy while enhancing performance and recovery*
Closely related to B vitamins and naturally found alongside healthy fats in avocadoes, dairy products, and red meat, L-Carnitine has been used extensively since the 1980s to promote fat-loss, increase energy levels, and protect the brain from free radical damage.1
Primarily found in our muscle and brain tissues, L-Carnitine is essential in the process of transporting long-chain fatty acids into the mitochondria of our cells. Mitochondria (the energy creators of our bodies), is then able to oxidize this fat into adenosine triphosphate (ATP) or the essential fuel that our bodies need to contract muscles and do just about anything else.1
Without L-Carnitine, it’s difficult for fats to be burned as fuel, so our body resorts to other sources of energy like muscle protein and sugar (glycogen). The result is diminished muscle strength, slow growth, and most notably, stubborn fat reserves that may be extremely difficult to remove.1,5,6
By assisting your body to transform long-chain fatty acids into energy, L-Carnitine is used both as a dieting tool and as a pre-workout supplement.8 Since L-Carnitine promotes fat as the primary source of energy, often greater amounts of glycogen are available in your muscles – allowing you to workout harder while ensuring that greater amounts of energy come from fat instead of muscle.4
L-Carnitine also assists the body by preventing lactic acid from accumulating in your muscles (lactic acid creates the burning feeling when you’re near exhaustion), which means you’ll be able to workout longer and recover more quickly.5,6
For Bulking, Dieting, and More
In short, since L-Carnitine can help limit the amount of new fat storage, it’s perfect for bulking or when trying to gain new, lean muscle. Since L-Carnitine also helps mobilize your body’s fat stores and turn them into energy for your workouts, it’s an essential supplement for anyone dieting or trying to lose weight while preserving lean muscle.1
UK researchers found that subjects taking L-Carnitine burned 55% less muscle glycogen, while increasing fat burning by 55%. They also found that subjects taking L-Carnitine could consume an extra 640 calories of fast-digesting carbs a day without gaining any additional body fat.7
Protect Your Brain and Body
In addition to these proposed fat and lactic acid fighting capabilities, L-Carnitine is also thought to be a potent antioxidant – supporting and protecting both brain and muscle functioning at the highest levels.2 By reducing free radical damage in the brain, it’s thought that L-Carnitine may even enhance cognition, reduce depressive symptoms, and improve sleep.*2
L-Carnitine only works if it’s absorbed
NutraKey’s Carnitine provides maximum absorption and bioavailability. Unlike some other forms of L-Carnitine, NutraKey has specially developed their L-Carnitine formula for maximum absorption and bioavailability – meaning that your body will get more out of each and every bottle.
