Description

Product Detail

L-Citrulline / Citrulline is an amino acid that supports the body in optimizing blood flow through its conversion to L-arginine and then nitric oxide. Nitric oxide is involved in vasodilatation, and low levels are associated with mental and physical fatigue and sexual dysfunction.

Citrulline, which is considered a non-essential amino acid synthesized in the intestinal tract from Glutamine, converts to Arginine in the endothelial cells. This biochemical process involves L-Aspartate and the enzymes Argininosuccinate Synthetase and Argininosuccinate Lyase, in the presence of ATP. Arginine is important for Nitric Oxide production for cardiovascular health; however, most Arginine is utilized in the liver and kidneys, and only a fraction is available for this purpose. Since Citrulline is a precursor to Arginine, it allows for increased and sustained Nitric Oxide production in the endothelium for support of circulatory function.

Oral Citrulline supplementation provides a readily available source of Citrulline for this purpose, and some recent research further indicates that Citrulline may be the preferred source of cellular Arginine. In addition Citrulline also increases energy, stimulates the immune system, and is essential for Urea Cycle function as well

Fuction of L-Citrulline:

1.L-citrulline is a naturally occurring amino acid, it is found in some foods like watermelons and is also
produced naturally by the body.
2.L-citrulline is used for Alzheimer's disease, dementia, fatigue, muscle weakness, erectile dysfunction, high blood pressure, and diabetes.

3.L-citrulline is used for heart disease, body building,increasing energy, and for improving athletic performance.

ECHEMI Editorial Reference

L-Citrulline is an amino acid derived from ornithine in the catabolism of proline or glutamine and glutamate, or from l-arginine via arginine-citrulline pathway.
Solid
L-citrulline is the L-enantiomer of citrulline. It has a role as an EC 1.14.13.39 (nitric oxide synthase) inhibitor, a protective agent, a nutraceutical, a micronutrient, a human metabolite, an Escherichia coli metabolite, a Saccharomyces cerevisiae metabolite and a mouse metabolite. It is an enantiomer of a D-citrulline. It is a tautomer of a L-citrulline zwitterion.|Citrulline is an amino acid. It is made from ornithine and carbamoyl phosphate in one of the central reactions in the urea cycle. It is also produced from arginine as a by-product of the reaction catalyzed by NOS family. Its name is derived from citrullus, the Latin word for watermelon, from which it was first isolated.|Citrulline is a non-essential amino acid. In hepatocytes, L-citrulline is synthesized in the urea cycle by the addition of carbon dioxide and ammonia to ornithine. L-citrulline is converted into L-arginine by the enzymes argininosuccinate synthetase and argininosuccinate lyase in the presence of L-aspartate and ATP. Subsequently, L-arginine is converted to nitric oxide by nitric oxide synthase and L-citrulline is regenerated as a by-product.

Its core products include multiple key varieties such as Semaglutide, Tirzepatide, Retatrutide, and Cagrilintide.
Eighty percent of the members in the company's core team possess over 15 years of experience in metabolic drug R&D. Many of them have led the launch of internationally blockbuster antidiabetic drugs. The team has successfully facilitated the approval of 12 innovative drugs, among which 5 have become top 50 best-selling prescription drugs globally. This has enabled the company to establish an irreplicable technical and experiential barrier in fields such as peptide drug molecular modification and long-acting formulation development.
On the R&D front, the company has built four national-level technology platforms, including peptide molecular design and oral formulation innovation, and holds more than 300 authorized patents. Its drug R&D cycle is 30% shorter than the industry average. On the production side, it owns the world's largest intelligent base for peptide drugs, with an annual production capacity of 500 kilograms. The base complies with the triple GMP standards of China, the United States, and the European Union, and achieves a 90% self-sufficiency rate in key raw materials, ensuring stable supply to over 120 countries. Additionally, the company has passed the unannounced inspections by the FDA (U.S. Food and Drug Administration) and EMA (European Medicines Agency) for 10 consecutive years.
Currently, Semaglutide has overcome the challenge of low oral bioavailability, achieving global sales of over 15 billion US dollars within 3 years of its launch. Tirzepatide surpassed 8 billion US dollars in sales in its first year on the market. Retatrutide has entered Phase III clinical trials, while the combination therapy of Cagrilintide is in Phase II clinical development. All these products demonstrate revolutionary therapeutic value. Looking ahead, the company will invest 25% of its annual revenue in R&D, focusing on the fields of metabolism and cardiovascular diseases, and is committed to becoming a global innovation benchmark in the biopharmaceutical industry.
