L-Methionine, also known as L-methionine, has the chemical formula C5H11NO2S and CAS number 63-68-3. It is an essential sulfur-containing amino acid. It appears as colorless or white, lustrous flaky crystals or a white crystalline powder with a slightly characteristic odor and a slightly bitter taste. As a food fortifier, it is listed in the national standard GB 1903.74-2025 and is mainly used in the pharmaceutical, food, and feed industries. It has strong hepatoprotective and detoxifying functions. It is used in biochemical research and as a nutritional supplement, and also as an adjunct treatment for pneumonia, cirrhosis, and fatty liver. It can also be used as a feed additive.

L-proline, a core raw material for collagen synthesis, is a major component of connective tissue proteins such as collagen and elastin, accounting for approximately 20% of the total amino acids in collagen. Its cyclic structure stabilizes the triple-helix conformation of collagen, directly affecting the strength and elasticity of skin, bones, and blood vessels.
Promoting wound healing and tissue repair: By accelerating fibroblast proliferation and collagen deposition, L-proline can shorten recovery time after trauma, burns, or surgery. It also enhances angiogenesis and improves local blood circulation.
Antioxidant and anti-stress protection: L-proline acts as an osmotic regulator, helping plants and some microorganisms resist adverse conditions such as drought and high temperatures. In animal cells, its metabolites may reduce oxidative damage by scavenging free radicals.
Supporting joint and cardiovascular health: As a structural component of cartilage matrix and arterial walls, L-proline supplementation helps maintain joint flexibility and vascular suppleness. It may inhibit low-density lipoprotein oxidation, slowing the progression of atherosclerosis.
Skin Anti-aging and Wound Care: As an oral beauty supplement or skincare ingredient, it improves skin elasticity and reduces wrinkles, especially suitable for those experiencing photoaging or collagen loss. Added to wound dressings or repair creams, it accelerates the healing of chronic ulcers and postoperative wounds.
Joint Health and Sports Nutrition: Used as a supplementary nutrient for osteoarthritis and osteoporosis, it synergistically enhances connective tissue repair with vitamin C and lysine. Added to sports supplements, it helps alleviate joint wear and tear and supports ligament repair.
Cardiovascular Health Products: As a component of vascular health formulations, it maintains arterial elasticity and microcirculation function. Combined with antioxidants, it helps prevent arteriosclerosis-related diseases.
Food Industry and Special Uses: Used as a flavor enhancer in beverages and seasonings to mitigate bitterness and enhance umami. Used as a culture medium additive in cell culture to promote the growth of certain mammalian cells. Serves as a research raw material for plant stress resistance agents.
For some products that require special packaging during transportation, we will carry out more delicate packaging. For example, retinal needs to be stored at -20 °C, so we choose cold chain transportation during transportation; deoxyarbutin will change color during transportation, so we will Vacuum packing of deoxyarbutin
