Collagen is the main structural protein found in the body's various connective tissues. As the main component of connective tissue, it is the most abundant protein in mammals, making up 25% to 35% of the body’s protein content. There are many different types of collagen. The five most common types are:
Type I: skin, tendon, vasculature, organs, bone
Type II: cartilage
Type III: reticular fibre found in connective tissue, commonly found alongside type I
Type IV: forms basal lamina, the epithelium-secreted layer of the basement membrane
Type V: cell surfaces, hair, and placenta
Over 90% of the human body’s collagen is type 1.
Your body naturally produces collagen, and you can also consume it through dietary sources such as chicken skin and fish skin as well as collagen supplements. Certain foods, such as animal skin and ligaments as used in bone broth, are rich in collagen. Vitamin C is needed for collagen synthesis, so having low levels of vitamin C may lead to impaired collagen production.
Collagen production naturally declines with age however, certain dietary and lifestyle factors can accelerate this process such as smoking or excessive alcohol intake.
Collagen supplements come from two main sources, bovine or marine.
Marine Collagen:
Skin Health: Marine collagen is known for its benefits to skin health. It helps improve skin elasticity, hydration, and reduces the appearance of wrinkles, promoting a youthful appearance.
Bioavailability: Marine collagen has a smaller particle size and lower molecular weight compared to other types of collagen, which enhances its absorption and bioavailability in the body.
Joint Health: Marine collagen supports joint health by providing the necessary amino acids to repair cartilage and reduce joint pain and inflammation.
Bone Strength: It helps maintain bone density and strength, making it beneficial for individuals at risk of osteoporosis or bone-related issues.
Sustainability: Marine collagen is often sourced from fish by-products, which makes it a more sustainable option compared to other sources of collagen.
Bovine Collagen:
Skin Health: Bovine collagen, like marine collagen, supports skin health by improving elasticity, hydration, and reducing wrinkles. It promotes a smoother and more youthful complexion.
Joint Health: Bovine collagen is rich in type I and III collagen, which are essential for maintaining healthy joints and connective tissues. It can help reduce joint pain and improve mobility.
Muscle Mass: Bovine collagen contains glycine, an amino acid that supports muscle repair and growth. It can be beneficial for athletes and individuals looking to increase muscle mass and strength.
Gut Health: Bovine collagen supports gut health by aiding in the repair of the gut lining, which can help alleviate symptoms of leaky gut syndrome and improve overall digestive health.
Bone Health: It helps in maintaining bone density and strength, providing support for those at risk of osteoporosis or other bone conditions.
Common Benefits of Both Marine and Bovine Collagen:
Hair and Nail Health: Both types of collagen can strengthen hair and nails, reducing brittleness and promoting growth.
Anti-Aging: Collagen supplementation, whether marine or bovine, supports overall anti-aging benefits by promoting skin, joint, and bone health.
Wound Healing: Collagen aids in the body's natural healing processes, making it beneficial for faster recovery from wounds and injuries.
Protein Source: Both types of collagen are excellent sources of protein, which is essential for various bodily functions, including muscle repair and enzyme production.
Hydration: Collagen helps improve skin hydration and overall moisture retention, contributing to a healthier and more radiant appearance.
While both marine and bovine collagen offer similar benefits, the choice between the two may depend on individual dietary preferences, potential allergies, and sustainability considerations.
