What is Marine Collagen?
Collagen is a fibrous protein that acts as a building block for skin, bones, muscles, tendons and ligaments in both humans and animals. It makes up about 30% of the protein in the human body and is the most abundant protein found in mammals.
Collagen has become a popular dietary supplement in recent years, with claims it can improve skin elasticity and hydration, reduce joint pain, support bone health and prevent bone loss. The collagen supplement market was valued at $7.5 billion globally in 2021 and is projected to reach over $10 billion by 2028.
Marine collagen specifically refers to collagen sourced from fish parts that are rich in collagen, such as scales, skin and bones. The main sources of marine collagen used in supplements include fish like salmon, cod, pollock, tilapia, carp and snapper.
Key Benefits of Marine Collagen
Some of the evidence-based benefits associated with marine collagen supplements include:
- Reducing signs of skin aging like wrinkles and dryness
- Supporting bone strength and mineral density
- Alleviating joint discomfort associated with arthritis
- Promoting heart health by reducing arterial stiffness
- Helping manage blood sugar levels and risk factors for diabetes
Bioavailability and Absorption
An important consideration with any collagen supplement is how well it is absorbed and utilized by the body. Studies show marine collagen peptides have higher bioavailability and better absorption compared to collagen from land animals.
The collagen in fish is more soluble and in a form that is easier for the body to break down and make use of. Enzymes naturally present in fish bone and scales pre-digest the collagen into small peptides that can be efficiently absorbed through the gut barrier.
Is Marine Collagen Vegan?
No, marine collagen supplements are not considered vegan because they are an animal-derived ingredient. Veganism strictly prohibits the use or consumption of any products that come from animals.
Vegans do not eat fish or take fish oil supplements. So while marine collagen offers some excellent health benefits, it would go against the ethics and principles of a vegan or plant-based diet.
Why Vegans Do Not Consume Marine Collagen
There are a few key reasons why vegans avoid marine collagen and any other supplements derived from fish or other sea creatures:
- Animal welfare - Vegans are ethically opposed to exploiting, farming or harvesting animals for food, materials or supplements.
- Sustainability - Overfishing threatens many fish species and ocean ecosystems.
- Health - Vegans typically aim to get nutrients only from plant foods, not animal sources.
- Environment - Fish processing for collagen can produce pollution if not properly regulated.
Vegan Alternatives to Marine Collagen
For those following a vegan lifestyle or plant-based diet, it's simple - marine collagen is off limits. However, there are some vegan alternatives that aim to provide similar beauty, health and wellness benefits:
- Vegan collagen boosters - These plant-based supplements contain vitamins and nutrients involved in supporting the body's natural collagen production like vitamin C, copper, zinc, and antioxidants.
- Marine algae collagen - A novel vegan collagen sourced from algae and seaweed that contains similar amino acids found in animal collagen.
- Vitamin C serums - Topical serums with vitamin C, retinoids, peptides and other ingredients can increase collagen in the skin without animal ingredients.
Ethical Considerations With Marine Collagen
If you don’t follow a vegan diet, marine collagen offers clear evidence-backed benefits as a supplement. However, there are still ethical and environmental considerations around the production of collagen from fish.
Responsibly sourced marine collagen aims to support sustainability of ocean resources while also harvesting collagen in an ethical way that minimizes animal suffering.
Sustainable Fishing and Processing
Overfishing is a major concern for the health of global oceans and fish populations. Collagen made from fish scraps and processing byproducts reduceswaste from seafood processing. Ethical marine collagen companies should adhere to programs for sustainable fishing and have transparency around their supply chains.
Animal Welfare in Harvesting
The concept of animal rights is important for some collagen consumers depending on their values and beliefs. Methods that maximize meat yield from fish and minimize waste align with principles of animal welfare. Using all parts of the fish to produce food, supplements and collagen allows the animal’s sacrifice to benefit humans.
Should You Try Marine Collagen?
Marine collagen offers science-backed wellness benefits for skin, hair, nails, bones and joints. Sourced responsibly, it can be an ethical animal-based supplement even if it does not qualify as vegan.
As with any supplement, consult your healthcare provider before starting, and be sure to choose reputable brands that ensure sustainable and ethical sourcing practices.
For those following plant-based diets, marine collagen would conflict with vegan principles. But vegan alternatives like algae collagen and collagen-boosting supplements can provide similar benefits.
FAQs
Is it safe to take marine collagen?
For most healthy adults, marine collagen supplements are considered safe, with very few side effects. As with any supplement, check with your doctor before starting, especially if you have food allergies or take medications.
What are the side effects of marine collagen?
Fish collagen is generally well-tolerated, even in larger doses. Mild side effects can include digestive issues like stomach upset, heartburn, or changes in stool. Allergic reactions are rare but possible if you have a fish allergy.
How long does it take for marine collagen to work?
Research shows it can take around 4-8 weeks of consistent use to notice benefits like improved skin hydration, elasticity, joint comfort or bone mineral density from a marine collagen supplement.
Is marine better than bovine or porcine collagen?
Evidence does suggest marine collagen from fish may be more bioavailable and absorb better compared to collagen from cows (bovine) or pigs (porcine). This leads to enhanced delivery of amino acids to support the building blocks of tissues.
