What is Marine Collagen and Why You Should Consider Using It?

Marine Collagen Source and Benefits

Marine collagen is sourced from oceanic elements such as fish scales, skin, and bones. I’ve found this type to be particularly remarkable for its extensive health benefits, notably in improving the beauty of skin and hair, as well as in enhancing joint and bone health.

I’ve learned that  marine collagen peptides are fundamental in supporting the structural integrity of various connective tissues in the body.  The US market for marine collagen, which was valued at over $253 million in 2022, is on the rise, expected to expand significantly in the coming years.

This surge is an indicator of the growing popularity of collagen products and the widespread recognition of its benefits.

For all these reasons, I feel it is important to discuss this subject in greater detail.

Today, I will address numerous important things to know about marine collagen, like:

  • Marine collagen source and composition
  • It is more bioavailable than its bovine counterpart
  • All the major benefits
  • Potential side effects

Without further ado, let us begin.

Source and Composition of Marine Collagen

Marine Collagen Source

Marine collagen is primarily sourced from the depths of the ocean. It is extracted mainly from the skin of wild-caught cod, a sustainable choice considering these fish are not endangered.  This sourcing method not only ensures the preservation of marine biodiversity but also provides a high-quality collagen source.

As a Type I, marine collagen stands out for its exceptional bioavailability, which is the highest among collagen sources. This means that once ingested, the body can absorb and utilize it more efficiently than other types. In contrast to marine variant, bovine, derived from cowhides, comprises both Type I and Type III.

While bovine is known for its benefits to joint health,  marine is specifically lauded for its effectiveness in enhancing the beauty and health of skin, hair, and nails.  This difference is partly due to the smaller size of the protein particles in marine, which significantly enhances its digestibility and effectiveness in the body.

The unique composition of marine collagen, with its high concentration of amino acids, makes it a highly sought-after ingredient in the beauty industry. .

Bioavailability and Effectiveness

Marine Collagen Bioavailability and Effectiveness

The bioavailability and effectiveness of marine collagen are central to its growing popularity as a health supplement. As a Type I, it stands out for its remarkable bioavailability, which is about 1.5 times higher than that of bovine variant.

This superior bioavailability means that when you consume marine collagen, your body can absorb and utilize it more efficiently, making it a more effective choice for those seeking the health benefits of collagen. This high bioavailability of marine collagen is largely due to the smaller size of its protein particles.

These smaller particles are easier for the body to break down and assimilate, facilitating Marine Collagen Comparing Effectiveness with Dietsmoother digestion and more efficient absorption.[/su_highlight] Once ingested, it peptides undergo a process of breakdown into amino acids.

These amino acids then circulate in the bloodstream, where they play a crucial role in various bodily functions. One of the most significant impacts of these circulating amino acids is their potential to signal the skin’s cells to ramp up new production. This signaling is vital in combating the natural decline of collagen in the body due to aging and other factors.

By stimulating the production of new collagen, it peptides can significantly improve skin health, enhancing its elasticity and overall appearance. This process is not just beneficial for the skin but also contributes to the health of joints and connective tissues.

The effectiveness extends beyond skin and joint health. Its role in supporting the overall structural integrity of the body, including the health of hair and nails, makes it a comprehensive health ingredient. Finally, bioavailability can depend on the form of your choice.

Dosage and Consumption

Marine Collagen Dosage and Consumption

The appropriate usage and dosage of marine collagen are pivotal in harnessing its full spectrum of benefits. Typically, the recommended daily intake of marine collagen varies between 2.5 grams and 15 grams. This range allows individuals to tailor their intake based on personal health goals and needs.

For instance, someone focusing on skin health might opt for a different dosage than someone looking to support joint health. It’s essential to opt for high-quality products from reputable brands. These brands often use wild-caught fish as their source, ensuring the purity and effectiveness.

 Products sourced from wild-caught fish are generally considered superior in terms of nutritional value and are less likely to contain contaminants compared to farmed fish.  Before adding marine collagen into your routine, consulting with a healthcare professional is highly recommended.

This is particularly important for individuals with specific health concerns, dietary restrictions, or allergies, especially to fish. A doctor can provide personalized advice, taking into account your health history and any potential interactions with existing medications or conditions.
