Optimum brain function and fat metabolism

Andrew Lessman's Acetyl L-Carnitine-500 is an ultra-high potency source of Acetyl L-Carnitine (ALC), which has long been recognized for its essential role in all fat and energy metabolism as well as healthy brain function. Acetyl L-Carnitine's importance for fat and energy metabolism stems from carnitine's role in the movement of all fat to the specific site in each cell where it can be burned. Not surprisingly, the highest levels of carnitine are found in organs performing the greatest amount of energy metabolism, including our brain, heart and skeletal muscles where over 98% of the body's precious reserves of Carnitine are found. Fat burning and weight loss are challenging and as long as we are making the appropriate dietary and lifestyle changes, we should also ensure an adequate supply of those nutrients required for optimum fat metabolism. Acetyl L-Carnitine's overall importance is underscored by its role in the brain where it can bypass the blood-brain barrier to deliver its benefits directly to the brain. At only 2% of bodyweight, the brain is relatively small, yet it consumes more than 20% of the body's total energy. A healthy brain requires an abundant and uninterrupted supply of energy and ALC supports those extreme energy requirements. ALC also supports healthy blood flow to the brain, which in turn promotes adequate oxygen and nutrient availability. ALC also facilitates the production of our brain's most vital neurotransmitter - acetylcholine. In short, Acetyl L-Carnitine (ALC) is not just essential for all fat metabolism, but it also plays a critical, central role supporting optimum brain function.
