        You may have already heard about L-carnatine. It's a popularly commercialized fat-burner. But did you know that your body can produce it on it's own. So, why is there a need to take l-carnatine supplement?

        L-carnatine is an amino acid that our kidneys and liver can normally produce from  amino acids "lysine" and "methionine." That means, your body is able to produce all the l-carnatine it needs. But there are times when it's production does not meet our body's requirement, such as during periods of strenuous exercises, renal failure, and certain genetic defects. Premature babies are also unable to produce enough l-carnatine.


        L-carnatine burns fat by transporting long-chain fatty acids found in the blood into the "power house" of cells called mitochondrias. Inside the mitochondias, these fatty acids are processed to produce energy for the body.
    L-carnatine serves a crucial role in transporting fatty acids inside of cells for energy production.


        Aside from this, did you know that L-carnatine also helps increase your body's endurance during exercise. This is due to the fact that it prevents the build-up of lactic acid within your body. When lactic acid accumulates on your muscle, it's acidity increases resulting to the burning and aching sensation you feel.

        In fact, it has been used by athletes as a supplement to enhance their performance.

 According to the National Academies's Food and Nutrition Board (FNB), l-carnatine is not an essential nutrient
