We prefer this brand because…...

L-Carnitine is the therapeutic form of the amino-acid carnitine, and we like the purity of this encapsulated version from Metabolic Maintenance. It is crucial to be sure that there are no traces of D-carnitine, the mirror image isomer, whichcan cause muscle pain or weakness: probably because it displaces and interferes with use of the natural L- form. Metabolic Maintenance has long experience producing a wide range of highly bio-available amino-acids and related nutrients: this brand has no fillers, is allergen-free, and easy to take. For cardiovascular benefits, men's health, muscle and energy, L-carnitine is more effective than the acetyl-L form used for brain health (see “Memoractiv”).

About L-carnitine

L-carnitine has a key role in energy generation, as it is essential for transporting long-chain fatty acids across the mitochondrial membrane for subsequent fat breakdown and energy generation. Its major health benefits are for cardiovascular and men's health, and athletic performance. Human heart muscle gets 70% of its energy from fat breakdown: congestive heart failure, cardiomyopathy, angina and mitral valve prolapse are associated with low carnitine and poor energy production. L-carnitine boosts fatty acid use, helps promote healthy rhythm, speeds recovery from a heart attack, and improves myocardial blood flow and cardiac output. Also L-carnitine can help blood flow in vascular disease, and improve blood lipids. In studies, with four months or more of use total cholesterol dropped by up to 20%, triglycerides lowered by up to 28%, and “good” HDL increased 12%, and lipoprotein(a) was reduced.

L-carnitine also has important roles for male fertility: low body carnitine levels are linked with reduced sperm count and motility. Several months of L-carnitine in studies has led to more live sperm released that move faster and in a more linear fashion. It can also help erectile dysfunction and libido.

For athletic performance, L-carnitine may improve running speed, decrease average oxygen consumption, heart rate, and lactic acid, and increase maximal oxygen uptake. Studies on high-repetition exercise suggest improved muscle recovery after L-carnitine supplementation.

L-carnitine also has useful roles for weight management and appetite control, healthy aging, and for individuals on dialysis or who are HIV-positive.

Cautions

Always take natural remedies under the supervision of your health care provider. Do not use L-Carnitine without the advice of your physician if you are taking propafenone and mexiletine as L-carnitine may potentiate their anti-arrhythmic effect in patients with ischemia. Mild gastrointestinal symptoms have been reported at higher levels of intake. Otherwise, L-Carnitine is considered remarkably safe. Some people may have an increased need for dietary Carnitine due to high-fat diets, certain medications, genetic predisposition, and low dietary levels of the precursor amino acids lysine and methionine. Do not use L-Carnitine during pregnancy without medical guidance.
