The potential dangers of marine collagen

Marine collagen has become a popular dietary supplement, widely recommended for its beneficial effects on skin, joints, and overall health. But despite its growing popularity, questions remain about its safety and possible side effects. This article explores the safety of marine collagen, analyzing both its benefits and the potential risks associated with its consumption.

What is marine collagen?

Marine collagen is a protein extracted primarily from fish scales and bones. It is highly prized for its high bioavailability , meaning it is more easily absorbed by the body compared to other forms of collagen, such as bovine collagen from cows. Type II collagen, often extracted from chicken cartilage, is also popular, but marine collagen is specifically sought after for its anti-aging potential and skin elasticity benefits .

Benefits of marine collagen

Marine collagen, extracted mainly from fish scales and bones, is recognized for its multiple health benefits. Regarding the skin, it promotes hydration and improves elasticity and firmness , thus reducing the signs of aging such as wrinkles and fine lines.

For bones, marine collagen stimulates bone collagen production , improves bone density , promotes fracture healing , reduces inflammation and protects against osteoporosis , helping to maintain strong, healthy bones.

When it comes to joints, marine collagen is essential for the regeneration of cartilage tissue , which helps maintain its flexibility and mobility. It also reduces joint pain associated with osteoarthritis and improves the health of tendons and ligaments , contributing to better elasticity and strength of these tissues. Regular intake of marine collagen can therefore be beneficial for supporting the overall health of joints , bones and skin , especially as natural collagen production declines with age.

Concerns and potential dangers

Despite its many benefits, consuming marine collagen is not without risks:

Digestive Disorders: Some users report side effects such as abdominal pain, bloating or allergic reactions, especially if the product is poorly purified or comes from questionable sources.

Risk of contamination: As the collagen is extracted from fish, there is a risk of contamination by heavy metals or other marine pollutants, depending on the quality of the water from which these fish come.

Kidney failure: Excessive protein consumption, including collagen, can put extra strain on the kidneys , which is especially concerning for people with a history of kidney disease.
