L-Calcium ascorbate (As-Ca), also known as calcium salt of vitamin C, has the chemical formula C12H14CaO12·2H2O and CAS Registry number 5743-28-2. It is a white to pale yellow crystalline powder, odorless, and readily soluble in water. This substance combines the antioxidant function of vitamin C with the nutritional fortification effect of calcium. Its stability is superior to that of ordinary vitamin C, and it is widely used in the food and pharmaceutical industries as an antioxidant and calcium supplement.In applications, it can be used as a fruit preservative, a meat antioxidant, and a nutritional additive in skincare products, and it also has the function of preventing osteoporosis.
Stable Vitamin C and Highly Effective Calcium Supplementation: L-Ascorbate calcium overcomes the oxidative weakness of ordinary vitamin C, significantly improving its stability. Once in the body, it dissociates into ascorbic acid and absorbable calcium, simultaneously fulfilling the physiological functions of both. Its solubility and ionization are higher than other calcium salts such as calcium gluconate, making it more easily absorbed by the body.
Antioxidant and Protein Deterioration Prevention: L-Ascorbate calcium has superior antioxidant properties compared to vitamin C, effectively scavenging free radicals and inhibiting lipid peroxidation. It can be used to prevent protein deterioration in fresh foods such as fish and meat, with significant effects.
Collagen Synthesis and Wound Healing: This component participates in the formation of intercellular collagen, maintaining normal capillary permeability. This helps promote tissue repair, accelerate wound healing, and maintain the health of skin, bones, and blood vessels.
Immunity Enhancement and Anti-Stress Effects: It stimulates the synthesis of adrenocorticotropic hormone, promotes antibody formation and the phagocytic capacity of white blood cells, thereby enhancing the body's immunity. During the body's biological oxidation process, it plays a role in transferring hydrogen and electrons, and has multiple functions such as detoxification, anti-scurvy, and anti-stress.
Food Antioxidant and Color Preservation: L-Calcium Ascorbate is widely used in ham, meat, soups, and wheat flour as an antioxidant to prevent rancidity of oils and denaturation of proteins without altering the original flavor. It can also be used in peeled or pre-cut fresh-cut fruits and vegetables (such as potatoes and burdock) to inhibit enzymatic browning and maintain product color and crispness.
Dietary Supplement and Fortification: Used as a nutritional supplement, it provides both vitamin C and calcium, helping to prevent deficiencies such as scurvy and rickets. Due to its high absorption rate, it is suitable for various populations requiring calcium supplementation, especially beneficial for preventing osteoporosis.
Feed Additive: In animal husbandry, adding it to feed can promote the growth of young animals, improve egg production in laying hens, and prevent deformities and anemia in fish caused by vitamin C deficiency.
Skin Care and Personal Care Products: It can be used as a non-ionic surfactant and nutrient in skin care and hair care products. Furthermore, due to its antibacterial properties, it is also used in lens cleaning.

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
