Without Carnitine fats cannot be burned for energy. Without energy, cells become weak or die. Because of this optimizing Carnitine levels has been found to have dramatic benefits for low energy, obesity, and fatigue. Controlled trials have demonstrated that Carnitine increases weight loss by promoting optimal fat burning by the mitochondria. Carnitine also helps promote heart health, maintenance of healthy cholesterol levels, and sports endurance and recovery. Acetyl-L-Carnitine is also contained in Carnitine Synergy and has unique brain health enhancing properties. Carnitine Synergy is unique in that it combines both of these valuable forms of Carnitine into one capsule.
