I am personally a big fan of l-carnitine supplementation. This amino acid compound, consisting of lysine and methionine, can be found in a couple of different forms. This article discusses L-carnitine tartrate, which is the form known to benefit athletic performance and recovery.
There are a couple of important points to consider when supplementing with carnitine. First of all, insulin must be present in the body for carnitine to enter muscle. One way of taking carnitine is to ingest carnitine with carbs so that there is an insulin release, but another effective option is to ingest carnitine with omega-3 fatty acids. Omega-3 fatty acids optimize cell membrane health, thus making cells more sensitive to insulin. Carnitine serves as a delivery system for fatty acids, so if carnitine levels are high, more fatty acids will be shuttled into cells to be utilized for energy.
Conversely, when carnitine levels are low, fewer fatty acids are moved into the cells and are instead stored as fat. Supplementation with carnitine before intense exercise, especially cardio, will switch the focus on burning fat rather than utilizing glycogen stores, resulting in longer sessions before glycogen stores are depleted. In addition, the presence of carnitine inhibits production of lactic acid, so recovery from intense exercise is more rapid.
Carnitine is not only an excellent performance supplement, it also serves as an excellent means of addressing metabolic syndrome. Metabolic syndrome, characterized by diabetes, atherosclerosis and high cholesterol, can be countered by carnitine’s ability to induce fat loss, prevent atherosclerosis and minimize the development of diabetes. After several months of carnitine supplementation, carnitine levels reach a level at which energy production and performance are enhanced. For this reason, it is best to consider carnitine an essential supplement in your daily regimen rather than as something taken only periodically.
Take 500 to 2,000 milligrams of l-carnitine tartrate daily, along with omega-3 fatty acids, for best results.
