Technical Data Sheet


Function and Effects

Increase muscle and lose weight
L-Ornithine is one of the growth hormone releasers used to increase lean muscle mass while decreasing body fat. Another important function of L-Ornithine is its use in detoxifying cells from harmful ammonia buildup.


Liver detoxification
Ornithine is a prerequisite for the metabolism of many other amino acids. It is mainly involved in the synthesis of urea and has a detoxifying effect on ammonia accumulated in the body. Therefore, ornithine is of great significance to human liver cells. On the basis of conventional treatment for patients with acute alcoholism, treating them with ornithine aspartate can help them regain consciousness faster and protect their liver function.

Anti-fatigue and improve immunity
Studies have found that supplementing with ornithine can increase strength and endurance. Ornithine can promote cells to use energy more efficiently and is often used as an anti-fatigue health supplement.

In addition, ornithine can increase the synthesis of polyvinylamine, promote cell proliferation, and play a certain role in improving immune function and anti-cancer function.


Application Fields


Nutritional supplements:
L-ornithine hydrochloride is a nutritional supplement that can provide the body with the ornithine it needs and is considered to have some potential health benefits. It is commonly used in sports nutrition and performance products.

L-ornithine hydrochloride is sometimes used as an ingredient in medications to treat some medical conditions or as a component of adjuvant therapy. For example, in the treatment of some liver and kidney diseases, L-ornithine hydrochloride is used to regulate amino acid metabolism and the urea cycle.

L-Ornithine HCl is sometimes added to cosmetics for its believed to have moisturizing and antioxidant properties that contribute to skin health and care.

Biological Synthesis Pathway

L-Ornithine is made in our bodies through a process that involves two other amino acids, L-Arginine and L-Proline. This synthesis requires the help of enzymes like Arginase, Ornithine Carbamoyltransferase, and Ornithine Aminotransferase.

♦ L-Arginine is transformed into L-Ornithine by an enzyme called Arginase.
♦ L-Ornithine plays a vital role in the urea cycle, where it helps convert ammonia byproducts into urea, which is then excreted from the body.

    1. What is the role of L-Ornithine in the urea cycle and ammonia detoxification?

    L-Ornithine plays a critical role in the urea cycle, a fundamental metabolic process responsible for the conversion of ammonia, a toxic waste product from the breakdown of proteins, into urea. The urea cycle occurs primarily in the liver and involves several enzymatic reactions. L-Ornithine functions at a key junction in this cycle. Here’s a simplified overview of L-Ornithine’s role:

    First, ammonia is converted into carbamoyl phosphate through the action of the enzyme carbamoyl phosphate synthetase I.
    L-Ornithine comes into play when carbamoyl phosphate combines with it, forming citrulline with the help of ornithine transcarbamoylase. This reaction takes place in the mitochondria.
    Citrulline is then transported into the cytosol, where it reacts with aspartate to form argininosuccinate, catalyzed by argininosuccinate synthetase.
    In the final steps, argininosuccinate is further broken down into arginine and fumarate. Arginine undergoes hydrolysis to produce urea and regenerate L-Ornithine.
    The urea, synthesized in the liver, is subsequently transported to the kidneys for excretion in the urine, thus effectively removing excess ammonia from the body.

    2. How does L-Ornithine supplementation affect muscle recovery and athletic performance?

    L-Ornithine supplementation may offer benefits to muscle recovery and athletic performance through several mechanisms:

    ♦ Ammonia Buffering: During intense exercise, ammonia levels in muscles can rise, contributing to fatigue. L-Ornithine can act as an ammonia buffer, helping to reduce ammonia levels and potentially delaying the onset of muscular fatigue.
    ♦ Enhanced Energy Production: L-Ornithine is involved in the synthesis of creatine, a compound important for ATP (cellular energy) regeneration during short bursts of high-intensity exercise. This can lead to improved performance during activities like weightlifting or sprinting.
    ♦ Improved Recovery: L-Ornithine may assist in muscle recovery by reducing post-exercise muscle soreness and promoting tissue repair. This can lead to quicker recovery times and less discomfort after strenuous training sessions.
