The recent years have seen one of the biggest trends in health and longevity which is collagen supplements. Collagen is becoming more and more popular to help fight wrinkles, joint health, tightening skin and creating a youthful glow. When it comes to researching the different types of collagen, one of the first question that everyone tend to ask is: Marine Collagen vs Bovine Collagen – Which is better?
We will discuss and compare both forms in this article which considering the scientific research, may preferably be used when.
What Is Collagen and Why Is It Important?
Collagen is the most abundant protein in the body and comprises a critical component of all connective tissue such as skin, bones, tendons (1). As we age, collagen production decreases, leading to signs such as wrinkles in the skin, joint pain, and loss of tissue elasticity (2). For this reason, collagen supplementation—especially after the age of 30—has become an essential part of healthy aging.
So far 28 collagen types have been described, whereof type I, II and III are the most abundant in humans.
-
Type I: Found in skin, bones, hair, etc.
-
Type II: Essential for cartilage tissue and directly related to joint health.
-
Type III: Found in the intestines, surrounding tissues of organs, and muscle connective tissue.
We also have a detailed article where we previously explained the functions of collagen in the body, the health issues that may arise from its deficiency, and the proper ways to use it. If you’re interested, you can access that article here.
Marine Collagen: Skin-Friendly
Marine collagen is derived from the skin, bones, and scales of cold-water fish. It largely contains Type I collagen, making it especially ideal for skin, hair, and nail health (3).
Advantages of Marine Collagen
-
Great bioavailability: This structure is considered to be more easily absorbed by the body (3).
-
Skin health benefits: It is thought that marine collagen peptides may have a positive effect on hyaluronic acid production, which helps the skin retain moisture, promoting elasticity and a youthful appearance.
A clinical study found that women aged 45–60 who used hydrolyzed marine collagen for 12 weeks experienced a 35% reduction in wrinkles, a 10–20% increase in skin elasticity, and a 9–25% improvement in overall skin appearance (4).
-
Suitable for dietary restrictions: Marine collagen is suitable for people who do not eat beef or pork.
-
Sustainability: Around 75% of fish weight becomes processing by-products, which can be repurposed into collagen,a more sustainable use of materials that would otherwise go to waste. The use of collagen-rich parts such as skin, bone and scale is eco-friendly and sustainable (5).
Disadvantages of Marine Collagen
-
Cost: It is generally more expensive than bovine collagen.
-
Limited applications: Its benefits are mostly restricted to skin and cosmetic purposes; joint or gut support is not as strong as with bovine collagen.
-
Taste and odor: Some users may notice a slight taste or smell from seafood sources.
Bovine Collagen: Support for Joints and the Body
Bovine collagen is derived from the skin, bones, and tendons of cows. Containing both Type I and Type III collagen, it contributes to the health of the skin, joints, and connective tissues (1).
Advantages of of Bovine Collagen
-
Skin Health: Types I and III collagen increase skin elasticity and moisture. Studies have shown that individuals using bovine collagen peptides experienced a 27% increase in skin hydration and a 60% reduction in wrinkle depth (6).
-
Joint Health: Bovine collagen is rich in glycine, proline, and hydroxyproline. These amino acids are critical for cartilage repair and reducing joint pain.
In a clinical study involving 274 patients with rheumatoid arthritis, those who took low-dose oral Type II collagen (20 µg/day) showed improvements in joint pain and function, with no reported side effects (7).
-
Gut Health: Glycine supports the integrity of the intestinal wall and may help prevent conditions like “leaky gut.” (1).
-
Cost: Generally more economical compared to marine collagen.
Disadvantages of Bovine Collagen
-
Bioavailability: Compared to marine collagen, its molecule size may be slightly larger, which can result in slower absorption.
-
Ethical and religious concerns: Not suitable for vegans, vegetarians, or individuals avoiding beef for religious reasons.
-
Animal-derived disease concerns: Although modern production processes are generally safe, some people may be cautious due to its animal origin.
Which One to Choose in Different Situations?
-
If skin health is the priority: Marine collagen stands out. Its smaller peptide structure may contribute more quickly to improving skin elasticity and moisture.
-
If joint and gut health are the priority: Bovine collagen is more advantageous due to its Type III collagen content.
-
If there are sensitivities: Marine collagen is more suitable for those avoiding beef products.
Does Bioavailability Really Make a Difference?
Many consumers ask, “Is marine collagen really absorbed better?”
Research indicates that marine collagen peptides have smaller molecular sizes, which may allow for faster absorption during digestion. However, some scientists note that this difference does not create a dramatic advantage in everyday use. In other words, both types of collagen can provide similar benefits when used regularly (1, 3).
Since collagen naturally exists as long and large protein fibers, it is difficult for the body to digest and absorb. Hydrolyzed collagen, or collagen peptides, are broken down into smaller fragments by enzymes, allowing them to be easily absorbed through the intestines and enter the bloodstream.
Research shows that consuming hydrolyzed collagen can increase skin hydration and elasticity, as well as support joint and connective tissue health (8).
Based on this scientific foundation, Augment Life Collagen Peptides contain highly bioavailable, easily absorbable proteins and essential amino acids, thereby optimizing the body’s natural collagen production and supporting skin, hair, and joint health.

Conclusion: Which Should You Choose?
There is no definitive “winner” between Marine Collagen and Bovine Collagen. The choice depends entirely on personal priorities and health goals.
-
For younger-looking skin → Marine Collagen
-
For stronger joints and gut health → Bovine Collagen
Remember: Collagen supplementation is not a miracle. The best results are achieved when combined with a balanced diet, adequate hydration, regular exercise, and healthy lifestyle habits.
