The Use of Marine Collagens: Applications and Benefits

Abstract

Collagen is an important structural protein found in the human body, functioning as a fibrous protein that provides durability, flexibility, and strength. Additionally, it serves as a fundamental building block that holds cells and tissues together, maintaining their integrity and resilience. Various types of collagen perform different functions in the body. Type I collagen is found in the skin, bones, tendons, connective tissues, and organs, providing durability and flexibility. Type II collagen, on the other hand, is located in cartilage and is essential for maintaining joint health. Type III collagen surrounds muscles, organs, and blood vessels, supporting tissue repair and elasticity. Type IV collagen is a component of the basal membranes beneath cells, providing cellular support.

Marine collagens are proteins obtained from fish and other marine organisms and stand out as environmentally friendly and sustainable sources. In recent years, marine collagen has become a significant component in the health, beauty, and dietary supplement industries. It is particularly widely used in areas such as skin health, joint support products, and wound healing.

Marine collagen has a smaller molecular structure compared to other animal-based collagens, making it more easily absorbed by the body and known for its higher bioavailability. These properties make marine collagen an effective supplement that provides quick results.

Primarily obtained from fish and shellfish, fish are among the most common sources of this protein. Fish skin, scales, bones, and fins, often considered waste, are utilized for collagen production. Species such as cod, salmon, tuna, and tilapia are frequently preferred for this purpose. Additionally, shellfish, such as crabs and shrimp, contribute to collagen production, and some species of jellyfish are also rich in collagen.

Marine collagen possesses hypoallergenic properties, meaning it has a lower risk of allergic reactions compared to animal-based collagens derived from cattle and pigs. This makes it a safer option, particularly for individuals without seafood allergies. Furthermore, marine collagen exhibits antioxidant effects, protecting the skin from damage caused by free radicals, which can help keep skin cells healthier and delay signs of aging.

All these properties contribute to the growing preference for marine collagen as a key ingredient in health and beauty products.
