As a dietitian, it is my role to ensure that my clients are well informed on numerous emerging supplements. One of the most asked questions popping up lately is: “What is Marine Collagen?” It’s super trendy right now on social media and at health expo, so, does it live up to the hype?

What Is Marine Collagen and How Is It Used?

Marine collagen is a type of collagen derived from the skin, scales and bones of fish and some invertebrates and it is high in type 1 collagen. Type I collagen is the most abundant type of collagen in our bodies. It is found in our skin, hair, nails, and connective tissues. It has a lower molecular weight with high bioavailability facilitating easy and fast absorption.

How Is Marine Collagen Derived from Fish?

The process starts with commonly used fish species, often from wild-caught species like cod, salmon, or tilapia.

Their by-products, including skin and scales, are collected.
The collected skins and scales undergo a thorough cleaning—a crucial step to remove impurities and ensure the safety of the final product.
Cleaned materials are then subjected to an extraction method to isolate the collagen. This process helps break down collagen for easier processing.
The extracted collagen is then hydrolyzed. Hydrolysis breaks down the collagen into smaller peptides, enhancing its bioavailability.

Common Applications of Marine Collagen in Supplements

Marine collagen is widely used in supplements for its biocompatibility, biodegradability and similarity to human matrix composition. Some of its applications include:

Used as a scaffold for skin, tendon, bone and cartilage regeneration.
Applied as membranes for periodontal therapy, bone grafts, and local drug delivery systems.
Utilized in sponges and films for cell adhesion and tissue repair.
Used in sponge-like products to control bleeding and aid in clot formation.
Supports controlled drug release using collagen-based membranes.
Used in skincare products to promote hydration, elasticity and anti-aging effects.
Functions as an additive for texture improvement and as an edible film for food preservation.

What Are the Benefits of Marine Collagen for Skin Health?

Marine collagen has gained popularity for its potential support to skin health. It is rich in peptides and amino acids that help maintain skin elasticity and hydration, promoting a youthful, glowing skin.

As we age, the ability of our body to produce natural collagen decreases, leading to aging signs like wrinkles, sagging face, and skin dryness. Our skin loses its elasticity and hydration, fortunately, marine collagen benefits counter these effects. It is primarily composed of Type I collagen, the most abundant type that provides support to the tissue of the body.

A recent study has shown that supplementing with low-molecular-weight collagen peptide, such as marine collagen, improves skin hydration and wrinkles reduction. Also, it helps stimulate the production of elastin and hyaluronic acid, which contributes to elasticity of skin for a more radiant complexion.

Fact: The cosmetic world is flooded with a variety of self-proclaimed anti-aging products. It is very important to do your own research to avoid any negative reaction.

How Does Marine Collagen Compare to Bovine Collagen?

Marine and bovine collagen are both popular choices for skin health promotion, but which one is more effective? They both may be essential collagen peptides, but their absorption, benefits, and sources differ.

Key Differences Between Marine and Bovine Collagen

Source

Marine collagen comes from fish skin, scales and bones.
Bovine collagen comes from cow hides and bones.

.Type

Marine collagen is rich in Type I collagen, the most abundant in the body, particularly in skin, hair, nails, and tendon.
Bovine collagen primarily contains both Type I and Type III collagen, which are great for skin, bones, joints, tendons and ligaments.

Absorption and Bioavailability

Marine collagen has smaller molecular peptides, making it easier to absorb and considered as more bioavailable than bovine collagen.
Bovine collagen still offers good absorption but may take a while for the body to utilize.

Why Choose Marine Collagen Over Bovine Collagen?

If your primary goal is for skin health improvement, marine collagen is for you. Its superior bioavailability and Type I collagen content, which is great for anti-aging and skin repair. Its sustainability is another factor, it is usually sourced from byproducts of the fishing industry, reducing waste and environmental impact.

Marine collagen is free from land animal associated concerns such as hormones and disease transmission risk compared to bovine collagen that relies upon cattle farming. However, marine collagen is not ideal for everyone. It tends to be more expensive and not suitable for individuals with seafood allergies. Despite this, marine collagen his a compelling choice due to its bioavailability and sustainability compared to bovine collagen.

What Effects Does Marine Collagen Have on the Body?

Marine collagen is an effective alternative to the traditional collagen sources. With its high bioavailability and rich amino acid profile, it can support tissue repair, hydration and elasticity. But how does it really affect our body? Let’s find out.

Collagen Production for Skin and Beyond

Marine collagen doesn’t just work on the surface but also supports your body’s natural collagen production. The amino acids in collagen, like glycine and proline, are the building blocks your body needs to repair and regenerate skin tissue.

As we aged, the collagen production of our body declined, resulting in wrinkles, dryness, and sagging. Marine collagen has gained attention for its high effectiveness in skin regeneration and anti-aging. Studies have shown that marine collagen peptides improve skin structure by promoting collagen synthesis and reducing transepidermal water loss.

Additionally, it supports fibroblast activity that is essential for skin repair and rejuvenation. It helps replenish collagen fibers, improves mechanical stability and mitigates the signs of aging. These properties make it a promising anti-aging formulation helping to maintain a youthful, resilient look.

How to Incorporate Marine Collagen into Your Routine

If you’ve been curious about how to use it, don’t worry, there are plenty of easy ways to make it part of your daily routine without overcomplicating things.

Maximizing the Benefits of Collagen

Consistency is the key, based on research of 8 weeks of daily supplementation of collagen peptide shows a positive result. For effective dosage, 10 grams for skin health goals and 20 grams for joint and muscle health.
Studies have shown that supplementation can enhance collagen production and synthesis. So what are you waiting for, pair your supplement with citrus fruits or a vitamin C-rich smoothie.
Proper water intake helps skin moisture, enhances elasticity and supports natural collagen production. Therefore, hydration and daily supplementation of collagen contributes to a healthier skin. Stay hydrated.

Final Thoughts: Is Marine Collagen Worth It?

Marine collagen presents a compelling option for those seeking skin, joint and bone health benefits. Marine collagen can be used as a tool in a healthy, well-rounded diet. Always remember that nutrition is never a one-size-fits-all.
