L-proline (or simply proline) is one of the twenty amino acids essential for the synthesis of proteins in the human body. At room temperature, it is a colorless to white crystal or crystalline powder with a slightly odorous and slightly sweet taste. Amino acids are a general term for a class of organic compounds containing amino and carboxyl groups. The presence of amino acids in the human body not only provides important raw materials for protein synthesis but also provides the material basis for promoting growth, carrying out normal metabolism, and maintaining life.
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
