What is Marine Collagen?
With high bioavailability, marine collagen is a popular protein supplement that is exceptionally rich in Type I collagen.Marine collagen is derived from the skin, scales and bones of fish, making it a good choice for pescetarian lifestyles.
Type I collagen is the most abundant collagen in the body and is crucial for maintaining healthy skin. Adding a marine collagen supplement to your routine is an effective solution to help support your skin’s structure and elasticity as the natural production of collagen decreases from around age 25.

How is Marine Collagen Sourced?
Marine collagen protein is derived from parts of the fish that otherwise go to waste, including skin and scales. These parts have high collagen content and are extracted through a process called hydrolysis, which produces hydrolysed collagen (or peptides).
The hydrolysis process breaks the larger collagen molecules down into smaller, more bioavailable peptides. Expect high-quality marine collagen in powder or liquid form for maximum benefits.

Key Supplement Benefits of Marine Collagen
Thinking about taking marine collagen supplements? Here are some of the main benefits:
● Anti-ageing – helps reduce wrinkles, hydrates skin and boosts skin firmness by adding high-quality collagen back into the skin.
● Superior absorption – marine peptides are smaller than other collagens, such as bovine (cow) or porcine (pig), which makes them more easily absorbed by the body.
● Stronger nails and hair – supplies the amino acids that create keratin, which improves nail strength and hair loss.
● Gut and muscle health – supports a healthy gut lining and aids muscle recovery, making it perfect for athletes and active people.
At Meaghers Pharmacy, we ensure our shelves are stocked with the most popular and effective collagen supplements. We offer marine collagen products in both powder and liquid sachet formats for added convenience and on-the-go intake.

What is Bovine Collagen?
Bovine collagen is a popular protein supplement extracted from cows, particularly their hides, bones, and connective tissue. Perfect for overall body support, this supplement is unique for being packed with both Type I and Type III collagen.
As mentioned above, Type I collagen is vital for healthy skin, whereas Type III is a key component for your muscles, organs, and blood vessels. This combination of collagen types makes bovine collagen peptides support a wide range of health benefits, including bone strength and gut health.
How is Bovine Collagen Produced?
The primary source of bovine collagen is cow hides, which are rich in connective tissue and sourced from grass-fed cows. The hydrolysis process breaks down collagen into smaller peptides, creating a tasteless, odourless collagen powder that dissolves easily, making it an incredibly bioavailable, high-quality supplement.
Key Benefits of Bovine Collagen Supplements
If you experience joint discomfort or want support for your mobility, bovine collagen is an excellent choice. Its blend of Type I and Type III collagen provides comprehensive support for your body's connective tissues.
● Reduces joint pain and inflammation
● Improves bone strength
● Helps with muscle recovery
Comparing Marine vs Bovine Collagen: Main Differences
The main difference between marine and bovine collagen is how the sources are sourced and the types of collagens they provide:
| Marine Collagen | Bovine Collagen |
|---|---|
| Derived from fish skin, scales and bones | Derived from cowhides, bones and connective tissue |
| Type I | Type I & Type III |
While both collagen supplements are highly absorbable due to hydrolysis into collagen peptides, marine and bovine supplements may also differ in bioavailability. Marine collagen peptides have a smaller molecular size, making themapproximately 1.5x more bioavailable than bovine collagen supplements.
Both marine and bovine collagen supplements are typically sold as hydrolysed collagen, but the naturally smaller marine collagen gives them an edge, allowing them to be broken down and absorbed into the bloodstream more quickly.
Choosing the Best Collagen Supplements for Your Needs
The best choice ultimately depends on your personal health goals. Do you want to focus on reducing fine lines and tackling other anti-ageing concerns? Or, are you seeking support for joints and muscle recovery?
Consider these points:
● Health Goals: Are you targeting skin, joint, muscle recovery, or gut health? Marine is best for skin concerns, whereas bovine is great for joint and gut health.
● Lifestyle & Dietary Restrictions: If you are a pescatarian, marine collagen is a suitable choice. If you have a fish allergy, you should opt for bovine collagen.
● Age: Younger individuals might focus on skin health with marine collagen, while those seeking joint support as they age may prefer bovine collagen.
Should You Combine Marine and Bovine Collagen?
Can't decide between marine and bovine collagen? The good news is you don't have to.
Combining marine and bovine collagen gives you the advantages of both Type I and Type III collagen, offering a broad spectrum of support for your entire body.
You can easily incorporate both into your routine by alternating between them each day, taking marine one day and bovine the next. Another option is to take a half dose of each collagen protein daily to cover all your bases, helping to improve visible signs of ageing, such as fine lines, while also supporting your joints and overall health.
Many high-quality supplements contain both marine and bovine collagen, combining benefits to support skin elasticity, joint health, and muscle recovery.

Frequently Asked Questions
Are Marine Collagen Supplements Better Absorbed Than Bovine Collagen?
Yes, marine collagen peptides generally have higher bioavailability. Due to their smaller molecular size, they are absorbed up to 1.5 times more efficiently than bovine collagen. This means your body can utilise the hydrolysed collagen more effectively, leading to faster results from your collagen peptides.
Are There Any Taste or Smell Differences Between Marine and Bovine Collagen Powders?
Thanks to modern processing techniques, high-quality marine and bovine collagen powders are typically formulated to be tasteless and odourless. This ensures you can easily mix your collagen powder into coffee, smoothies, or other foods without affecting the flavour or smell, making your daily supplementation a seamless experience.
Can People with Dietary Restrictions (such as pescatarians or vegetarians) Take Either Type of Collagen Supplement?
Pescatarians can take marine collagen as it's derived from fish. However, both marine and bovine collagen are animal-based, so they are not suitable for vegetarians or vegans.
Those following a plant-based diet should look for vegan collagen boosters that support the body's collagen production.
