Glucosamine Sulfate is an amino monosaccharide which exists in the body, especially in articular cartilage. It selectively ACTS on osteoarthritis, blocks the pathological process of osteoarthritis, stimulates chondrocytes to produce glycoproteins with normal polysaccharide polymer structure, and also inhibits the activity of enzymes that damage cartilage, such as collagenase and phospholipase A2.Collagen peptide is a kind of repairing collagen. With the growth of human age, collagen will gradually decrease and lose. Taking collagen peptide can moisturize the skin, restore its elasticity, resist aging, resist oxidation and prevent the generation of fine lines. It can improve the microcirculation of the body, and remove spots, sunburn, chloasma and senile plaque. It can increase skin moisture, brighten skin tone, and make skin more compact, shiny and delicate. It can also enhance human immunity and regulate endocrine function.
