Krill Protein Peptides

Krill protein peptides are small-molecule active peptides extracted from Antarctic krill. Their main effects include antioxidant, anti-inflammatory, lipid-regulating, immune-enhancing, and skin-health-promoting effects. Combining the high-quality protein and phospholipids of krill, they are more easily absorbed and utilized by the human body, making them suitable as a dietary supplement to help improve sub-health conditions.

Antarctic krill peptides are refined from Antarctic krill powder through a complex gradient enzymatic hydrolysis, multi-stage separation and purification, and spray drying process. Antarctica, known as the "end of the world," is the most isolated continent with the purest waters. Antarctic krill are key species in the Antarctic ecosystem and are considered an inexhaustible protein resource for humankind. Antarctic krill protein peptides are extremely nutritious, with a protein content exceeding 50%. In addition, Antarctic krill contains abundant essential amino acids, vitamin A, and astaxanthin, which effectively protect the cardiovascular system and prevent aging.

Antioxidant and Anti-aging Effects

Krill protein peptides are rich in astaxanthin and polypeptides, which can neutralize free radicals and reduce oxidative damage. Studies have shown that their antioxidant capacity is hundreds of times that of vitamin C, which can slow down cell aging, protect skin collagen, and improve skin elasticity. Furthermore, astaxanthin can penetrate the blood-brain barrier, offering some protection to the nervous system.

Anti-inflammatory and Cardiovascular Protection
EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) in krill protein peptides have significant anti-inflammatory effects, inhibiting the release of pro-inflammatory factors (such as IL-6 and TNF-α). Clinical trials have found that long-term supplementation can reduce blood viscosity, help regulate blood pressure and cholesterol levels, and has potential benefits in preventing cardiovascular diseases such as atherosclerosis and coronary heart disease.

Regulation of Metabolism and Immune Function
Their unique phospholipid-binding protein structure promotes lipid metabolism, helping to lower triglycerides and low-density lipoprotein (LDL). Simultaneously, the small molecule peptides can be directly absorbed by the intestines, stimulating immune cell activity and enhancing the phagocytic capacity of macrophages. For individuals with weakened immunity or those recovering from surgery, it may shorten the recovery period.

Skin Repair and Cosmetic Support

Collagen peptides and amino acids (such as proline and glycine) in krill protein peptides can promote the regeneration of dermal fibroblasts and accelerate wound healing. Experimental data show that after 8 weeks of continuous intake, the skin moisture content of subjects increased by approximately 15%, and the area of ​​UV-induced erythema decreased by 30%.

Anti-fatigue, hypoxia tolerance, and enhanced immunity

Antarctic krill peptides significantly increased the survival time, oxygen consumption, and swimming time of mice, increased LDH, liver glycogen content, LA clearance rate, and liver and spleen weight; and decreased LA and BUA content. Immunological experiments demonstrated that Antarctic krill peptides could increase the proliferation rate of splenic lymphocytes, delayed-type hypersensitivity, antibody-producing cell number, serum hemolysin levels, phagocytic cell carbon clearance capacity, and NK cell activity in mice. These results indicate that Antarctic krill peptides have significant effects in improving anti-fatigue, hypoxia tolerance, anti-aging, and enhancing immunity.

Lowering Blood Pressure and Blood Sugar

Krill peptides contain ACE inhibitory peptides and DPP-IV inhibitory peptides, which can lower blood pressure and blood sugar.

Preventing Osteoporosis

Krill peptides can improve intestinal calcium absorption in ovariectomized osteoporotic mice and increase bone mineral content in ovariectomized mice. Antarctic krill peptides can significantly improve osteoporosis in bilaterally ovariectomized rats, and its mechanism of action is related to downregulating the Wnt/β-connector protein pathway and reducing the high bone turnover rate in osteoporotic rats. Phosphorylated krill peptides can significantly inhibit bone resorption in osteoporotic rats, possibly related to inhibiting the secretion of inflammatory factors.

Antibacterial Effects

Antarctic krill peptides have a significant inhibitory effect on Staphylococcus aureus. The mechanism is to disrupt the bacterial cell wall and cell membrane, change cell membrane permeability, cause a large amount of intracellular material to leak out, and thus cause bacterial death.

• Functional Foods: Krill protein peptides can be added to sports nutrition products, senior nutritional supplements, and beauty foods to enhance immunity, combat fatigue, and improve skin health.

• Health Foods: Several brands have launched dietary supplements containing krill protein peptides, suitable for groups such as those with weakened immunity, high blood pressure, high cholesterol, high blood sugar, osteoporosis, those engaged in mental work, and the elderly.
