Medicine Grade L-Leucine Amino Acid Slows Muscle Degradation by
Facilitating the Creation of Muscle Proteins
Leucine is an essential amino acid, and it cannot be synthesized by
the human body. It is one of the three branch-chained amino acids.
It makes up one of the components of the collective term protein.
The human body is roughly 16 percent protein. Protein plays an
essential role in every cell of our body.
There are 20 amino acids used by the human body and eight of them
cannot be synthesized. Leucine is one of those that must be
acquired by diet. Leucine is manufactured by plants and
microorganisms. Leucine can be found in high concentrations in the
following foods: soybeans, lentils, cowpeas, beef, peanuts, fish,
chicken, nuts, almonds, and eggs.

Leucine slows muscle degradation by facilitating the creation of
muscle proteins. Leucine is used by the liver, body fat, and
muscle. Leucine increases energy and endurance. It also plays an
important role in the synthesis of hemoglobin. Leucine helps
maintain proper blood sugar and plays a role in human growth
As we age, the process of protein synthesis (rebuilding new and
existing tissue) begins to slow. Unfortunately the process of
breaking down existing tissue continues at a normal pace. A study
performed with eight month and 22-month old rats showed that
increased intake of l-leutine actually reversed the imbalance of
protein sysnthesis and breakdown.
When we consume protein, our body begins to breakdown the protein
that already exists and replaces it with the newly synthesized
protein. As we age, the process of synthesizing newly consumed
protein slows. However, the process of breaking down protein in our
muscles and bones does not. This leads to muscle loss and bone
frailty as a result. Increased consumption of l-leucine has shown
promise in that it helps to rebalance this equation in rats. This
research suggests that it would have a similar affect in humans.
