Different Types of Collagen

There are at least 28 varieties of collagen, but five are predominant and vital to our health.

Type I Collagen

Description and Sources: Type I collagen is the most abundant, found in skin, bones, tendons, and ligaments, sourced from bovine and marine collagen.

Benefits: It enhances skin elasticity, hydration, and wound healing.

Type II Collagen

Description and Sources: Predominantly located in cartilage, Type II collagen is chiefly derived from chicken.

Benefits: It bolsters joint health, benefiting those with arthritis.

Type III Collagen

Description and Sources: Present in skin, lungs, and blood vessel walls, it’s commonly sourced from bovine collagen.

Benefits: It helps maintain organ structure and skin elasticity.

Type IV Collagen

Description and Sources: Found in skin layers, Type IV collagen is crucial for forming the basement membrane.

Benefits: It aids in filtration and structural support to various tissues.

Type V Collagen

Description and Sources: Located in the cornea, certain skin layers, hair, and placenta, typically sourced alongside Type I and III.

Benefits: It is essential for cell surfaces and hair health.

Sources of Collagen

Collagen can be procured from various animals, each offering distinct benefits.

Animal-Based Collagen

Bovine Collagen: Derived from cows, rich in Type I and III, beneficial for skin, hair, and nails.

Porcine Collagen: Obtained from pigs, similar to human collagen, effective in skin and cartilage repair.

Chicken Collagen: Rich in Type II, ideal for supporting joint health and reducing inflammation.

Marine Collagen

Sources and Extraction Process: Extracted from the skin, bones, and scales of fish. The process involves hydrolyzation, breaking down collagen into more digestible peptides.

Why Marine Collagen is the Best

Higher Bioavailability

Marine collagen peptides are smaller, facilitating easier absorption by our bodies, leading to quicker and more effective results.

Sustainability and Environmental Impact

Marine collagen is sourced from fish parts that would otherwise be discarded, making it an eco-friendly option. This sustainable approach minimizes waste and supports environmental conservation.

Purity and Safety

Marine collagen is less likely to harbor contaminants compared to land animal collagen. It’s also free from bovine spongiform encephalopathy (BSE).

Health Benefits Specific to Marine Collagen

Marine collagen is renowned for enhancing skin elasticity, hydration, and reducing wrinkles. It also benefits joint health, bone strength, and overall vitality.

Comparing Marine Collagen to Other Collagen Types


Marine collagen stands out for its superior absorption and bioavailability, leading to more rapid and noticeable results.

Absorption Rate

The smaller peptide size of marine collagen ensures it is absorbed up to 1.5 times more efficiently than other collagen types.

Environmental Factors

Marine collagen, a byproduct of the fishing industry, is more sustainable compared to bovine or porcine collagen, which require more resource-intensive farming practices.

Consumer Preferences

With growing environmental consciousness, more consumers favor marine collagen for its eco-friendly benefits and superior efficacy.

How to Incorporate Marine Collagen into Your Diet


Marine collagen supplements are available in powder, capsule, and liquid forms, easily integrating into your daily regimen for a convenient collagen boost.

Food Sources

Incorporate fish such as salmon and tuna into your diet. Fish skin and bones are rich in collagen, so consider making fish broth or soups.


Add marine collagen powder to smoothies, coffee, or yogurt. It can also be used in baking for collagen-boosted treats.

Potential Side Effects of Collagen Supplements

Allergic Reactions

Although rare, some individuals may experience allergic reactions to marine collagen. Always check for potential allergens before consumption.

Digestive Issues

Some might encounter mild digestive discomfort when starting collagen supplements. It’s advisable to begin with a small dose and gradually increase it.

Safety Considerations

Opt for high-quality, tested products to avoid contaminants. Consult your healthcare provider if you have underlying health conditions.

Choosing the Right Collagen Supplement

Factors to Consider

Look for hydrolyzed marine collagen for better absorption. Consider source, purity, and brand reputation.

Reading Labels and Ingredients

Check for additives, fillers, and artificial ingredients. Choose supplements with minimal and natural ingredients.

Trusted Brands

Research and select brands known for quality and transparency. Read reviews and check for third-party testing certifications.
