We help you source L-Leucine in China

Our Advantages:

We are currently dealing in lipoic acid, calcium gama-hydroxybutyrate and hyaluronic acid.

We have a great advantage in the supply chain of amino acids, a good amino acid plant needs to have fermentation advantages, high costs and barriers, and also high environmental requirements.

We know every amino acid plant in China and can provide you with the most accurate information.

We have a 20+ year track record of working with suppliers in China and rating reports on them, and we keep our suppliers updated with the latest news so our customers can get the latest supplier reports. We know the market well and have early warning notifications on upstream raw material prices to help you build a stable supply chain.

When selecting suppliers, our procurement specialists will audit the qualification of suppliers, conduct thorough investigations such as field visits and sample testing, and make ratings to ensure the authenticity and legality of supplier information.

We have a long-term stable cooperation with GLP laboratories, encounter customer test results and supplier test results do not match the situation, we will commission a third party to test to ensure the accuracy, authenticity and reliability of the experimental results. In this way, we can effectively control the product quality problems.

We have a long-term cooperative warehouse and can follow up packaging and labeling according to safety regulations and customer requirements. In order to effectively prevent damage to the goods in transit, we have prepared various reinforcement measures and packaging solutions.

We have a number of international freight companies with whom we have long-standing cooperation, and we can choose several route options according to the customer's requirements.

Introduction:

L-Leucine is an essential amino acid that consists of two other Amino Acids - L-Isoleucine and L-Valine.

It is not synthesized by the human body and must be ingested through diet. It is the most abundant free-form amino acid in muscle tissue, representing 35% of all amino acids.

It can find it naturally in food sources such as soy, red meat, and fish. A good source of L-Leucine is eggs and soy proteins.

L-Leucine is a white crystalline powder that has a strong, fishy odor and an acidic taste. It belongs to the alpha amino acids group, and it contains both L-isomer of Leucine and D-isomer of Isoleucine.

Applications:

L-Leucine is a branched-chain amino acid that plays a building block role in muscle development.

It plays a crucial role in the complete synthesis of proteins that build muscle mass. Scientists believe that the building blocks of proteins are responsible for muscle growth and L-Leucine is a crucial component in this process.

In the body, L-Leucine is converted to L-Isoleucine and L-Valine. These three amino acids play a significant role in muscle metabolism and control protein synthesis. In terms of functions, L-Leucine has been found to improve glucose tolerance and utilization and decrease the risk of obesity.

Furthermore, L-Leucine may also be beneficial to patients with liver cirrhosis, as it can help regulate the metabolism of fat and proteins. Again, a growing body of research shows that L-Leucine can effectively improve athletic performance and recovery.
