Carnitine is an amino acid that is naturally synthesized in the body from the amino acids lysine and methionine and found in high quantities in animal products such as beef, dairy, chicken and fish. It has been studied for its health benefits and it is now considered to be a very important nutrient for heart health, brain function, and its other benefits.
Studies have found that the amino acid may be effective for managing low blood flow to the heart (ischemia) and may improve poor circulation in general. Heart muscle that has been damaged is low in carnitine, so supplementing with the amino acid may be beneficial to patients with failing hearts. It may also reduce the chance of mortality for patients who have suffered a heart attack.
Mayo Clinic found that carnitine can reduce abnormal heart rhythms
A study by the Mayo Clinic found that the amino acid can reduce abnormal heart rhythms for patients who are having a heart attack. The study found that the amino acid had several benefits for patients who had suffered a heart attack. Mayo Clinic found that carnitine reduced mortality by 27% for patients who had a heart attack. There was also a 40% reduction in angina (heart pain) and a 65% reduction in abnormal heart rhythms compared to the group that did not take it.
Carnitine may be effective for managing peripheral artery disease
There have also been studies on the effect of the amino acid on patients who suffer from peripheral artery disease which causes a restricted blood low in the limbs among several other health issues. Patients with this disease have difficulties exercising and walking. A European study found that carnitine supplements may help patients with peripheral artery disease by improving the performance of skeletal muscle in the limbs.
The European study found that patients who took the amino acid at 2 g/day showed a major improvement in their maximum walking distance and their quality of life compared to patients who did not take carnitine. This study and many others continue to confirm that carnitine is a vital nutrient for the healthy function of the heart and other muscles in the body.
