Collagen is a key structural protein that is the primary component of connective tissue in animals, including skin, bones, tendons, ligaments, and cartilage. Its primary role is to provide strength and elasticity to these structures, which is essential for their strength and function. In the case of skin, collagen helps maintain its firmness, elasticity, and moisture levels, which contribute to the animal’s healthy, youthful appearance. In the context of joints, collagen helps maintain the integrity of cartilage, which is key to cushioning the effects of wear and tear and preventing conditions such as osteoarthritis. Collagen’s shock-absorbing properties help protect joints from impacts and stresses that can lead to damage. Collagen also plays an important role in wound healing, as it is essential for the formation of new tissue during the regenerative process. Its presence accelerates the healing process, improving both the speed and quality of tissue regeneration. As animals age, collagen production declines, which can lead to weaker connective tissue, reduced skin elasticity, and decreased joint function. Collagen supplementation may be beneficial to support the health, endurance, and overall well-being of pets, especially older ones.
