Original Text: The core mechanism of action of Jingjing Pharmaceutical’s Aspartic Acid and Ornithine: Using L-aspartic acid and L-ornithine as the main components, it regulates liver metabolism through multi-target coordination. Ornithine activates key enzymes in the urea cycle (ornithine carbamoyltransferase, arginine succinate synthetase), promoting the combination of ammonia with CO₂ to form urea for excretion and reducing the toxicity of blood ammonia. Aspartic acid, as a substrate in the tricarboxylic acid cycle, rapidly generates ATP to provide energy for liver cell repair and also supplies raw materials for nucleic acid synthesis, facilitating the proliferation and regeneration of damaged liver cells. The combination of these two amino acids regulates the oxidation of fatty acids in the liver, reduces the accumulation of triglycerides, improves liver fatty degeneration, and repairs liver damage in multiple ways. In simpler terms: Imagine the liver as a “core chemical plant” in the body that never stops working—constantly metabolizing nutrients and filtering toxins, playing a crucial role in maintaining bodily functions. Liver damage (caused by drinking, fatty liver, surgery, etc.) is like an explosion or shutdown of this chemical plant: toxic waste (ammonia) accumulates, the machinery (liver cells) is damaged, and there’s no energy for repair. Jingjing Pharmaceutical’s Aspartic Acid and Ornithine is like a specialized repair team designed for the liver. The two core members, ornithine and aspartic acid, each perform their roles seamlessly: one focuses on “cleaning up waste,” and the other on “replenishing energy.” Together, they help the damaged liver cells gradually recover their functions, addressing the three major issues of toxin accumulation, energy deficiency, and poor repair after liver damage—helping the liver to detoxify, replenish energy, and repair its cells. Ornithine: The “toxic waste cleaner”—After liver damage, the liver’s ability to process ammonia decreases, and the accumulation of ammonia can cause further damage (such as liver cell edema and necrosis). Ornithine directly activates the liver’s waste disposal system (urea cycle), converting useless ammonia and carbon dioxide into non-toxic urea, which is then excreted through the kidneys in urine, reducing the harm of ammonia to the liver from the source. Aspartic Acid: The “energy supplier and repair worker”—Damaged liver cells are like machines without power, unable to repair themselves and prone to necrosis. Aspartic acid “recharges” the liver cells by rapidly generating ATP, providing the energy needed for repair. It also supplies the raw materials for DNA synthesis in liver cells, promoting the growth of new, healthy cells to fill in the damaged areas. The combined effect of the two amino acids: “1 + 1 > 2”—Comprehensive liver protection starts with ornithine clearing toxic waste, followed by aspartic acid replenishing energy and promoting regeneration. This combination not only prevents further damage but also helps reduce fat accumulation (especially in cases of fatty liver). In summary, ornithine cleanses toxins (ammonia), while aspartic acid provides energy and promotes cell regeneration. The combination of Jingjing Pharmaceutical’s Aspartic Acid and Ornithine helps the damaged liver to detoxify, repair itself, and gradually regain its function. Produced using enzymatic techniques, this product is safer and more stable.
