L-Leucine is an essential amino acid, meaning it can not be made by the body, and must be acquired through food or dietary supplements. Leucine is classified as a "branched-chain amino acid" (BCAA). It comprises about 8% of the total amino acid count in your body's protein structures and is the fourth most concentrated amino acid in skeletal muscle tissue.

L-Leucine stimulates muscle protein synthesis and may be the major fuel involved in anabolic (tissue building) reactions. This makes them especially important for body builders and other athletes in sports that demand explosive strength.

The branch chain amino acids valine, leucine, and isoleucine enhance protein synthesis in liver cells and muscle cells and help promote muscle recovery after exercise. They contribute to energy production in the body by being oxidized in the cell’s mitochondria. Branch chain amino acids are used by body builders and athletes to produce an anabolic effect and assist in the repair of micro tears in muscle tissue that are a normal result of exercise. Leucine is thought to be the most effective BCAA for preventing the body’s burning of muscle stores for energy during intense workouts because it is converted to glucose more quickly than isoleucine and valine.

      • Maintains nitrogen balance.
      • Preserve lean muscle tissue.
      • Supplies the body with energy when under stress.
      • Preserves muscle glycogen (glucose stored in muscle used to power muscular contraction).
      • Enhances thinking abilities that can decline as physical activity becomes more intense.

The benefits of L-Leucine Ethyl Ester:  Amino Acid Esters are amino acids with an ester molecule attached. Esters are organic compounds that are formed by esterification, which is the reaction of carboxylic acid and alcohols. Esters are organic compounds that help shuttle the amino acid across lipid membranes of the gut and directly into the bloodstream for direct transport to your cells. This prevents the amino acid from being destroyed in the gut and drives more of the free form amino acid directly into muscle tissue where it can be more efficiently used for its intended purpose.

Free form amino acids have inherent limitations such as limited absorption through the intestine. Whereas amino acid esters can pass through the intestine largely intact, regular free form aminos can be significantly degraded in the intestine, leaving only trace amounts of the ingested dose active. Because of the rapid breakdown of some amino acids
in the intestine, its beneficial effects can be limited. Ethyl ester amino acids are thought to have a much better absorption rate and a longer half-life in the body than regular free from amino acids because it is slightly more lipophilic.

Amino acid ethyl esters are technically amino acids derivatives. Their ergogenic effects are similar to those of their base free form amino acids, but the presence of an ester will make the ergogenic effects of more pronounced. The presence of the ester not only enhances the function of amino acid and overcomes its inherent limitations, but the presence of an ester and increased absorption also reduce the need for large doses, which may put less stress on the body.
