Can You Take Marine and Bovine Collagen at the Same Time?

December 19, 2025 •

4 min read

Over 90% of the body's collagen is type I, found primarily in skin, tendons, and bones, and many supplements focus on this type. You can, in fact, take marine and bovine collagen at the same time, a strategy that is not only safe but often recommended to broaden the spectrum of health benefits. This approach leverages the unique properties of each source for more comprehensive support.

Quick Summary

Combining marine and bovine collagen is a safe and effective strategy for holistic wellness. Marine collagen offers enhanced skin benefits due to its high bioavailability, while bovine collagen provides comprehensive support for joints, gut, and connective tissues. Together, they create a broader amino acid profile to target multiple health goals simultaneously.

Key Points

Safety: It is completely safe to take both marine and bovine collagen at the same time.
Broader Benefits: Combining both sources provides a wider range of collagen types (Type I and III) and a more comprehensive amino acid profile for full-body support.
Targeted Action: Marine collagen (Type I) is highly bioavailable and excellent for skin, hair, and nail health, while bovine collagen (Type I and III) offers more robust support for joints, bones, and gut integrity.
Dosage Flexibility: You can take them together or split the doses throughout the day, depending on what best fits your routine.
Consistency is Key: For optimal results, regular, consistent intake is more important than the specific timing.
Allergy Check: Individuals with fish or beef sensitivities should choose a single source or a plant-based alternative.
High Bioavailability: Ensure both supplements are hydrolyzed for better absorption by the body.

Why Combining Collagen Sources is Beneficial

Yes, it is perfectly safe and often advantageous to take marine and bovine collagen simultaneously. While both are excellent sources of type I collagen, they also offer distinct amino acid profiles and benefits that, when combined, provide more comprehensive support for your entire body. This dual-approach is designed to address a wider range of wellness goals, from enhancing skin elasticity to strengthening joints and improving gut health.

Marine collagen, sourced from fish scales and skin, is primarily type I collagen and has a smaller molecular size than bovine collagen. This smaller size gives it higher bioavailability, meaning it's absorbed more quickly and efficiently by the body, making it particularly effective for skin, hair, and nails. The amino acids in marine collagen are often praised for their ability to boost skin hydration and elasticity, reduce fine lines, and support healthier hair and nail growth.

Bovine collagen, derived from cow hides and bones, is rich in both type I and type III collagen. Type III collagen is essential for the structure of organs, muscles, and blood vessels, and it works synergistically with type I to promote skin plumpness and elasticity. More importantly, the combination of type I and type III in bovine collagen makes it especially beneficial for supporting joint, bone, and gut health. The presence of type III is particularly valuable for strengthening the gut lining and improving overall digestive function.

By taking both supplements, you get a full-body approach to collagen supplementation. For instance, you could be giving your skin a quick, bioavailable boost with marine collagen while providing more sustained, comprehensive support for your joints and gut with bovine collagen. The idea is that instead of choosing one or the other, you maximize the potential benefits of both.

How to Combine Marine and Bovine Collagen

There are several ways to incorporate both marine and bovine collagen into your daily routine. The most common and straightforward method is to simply take them together. Since they don't compete for absorption, you can mix both powdered forms into your morning coffee, smoothie, or tea. Many multi-collagen products on the market already combine different sources for convenience.

Alternatively, you could split the dosages throughout the day. Some people prefer taking marine collagen in the morning to kickstart their day with a beauty boost, and bovine collagen in the evening to support overnight tissue repair and aid sleep. You could also cycle between them, alternating between marine and bovine collagen on different days or weeks. For instance, focusing on bovine for a month to address joint concerns, then switching to marine for skin health. Consistency, rather than timing, is the most crucial factor for seeing results.

Comparison of Marine vs. Bovine Collagen


Feature	Marine Collagen	Bovine Collagen
Primary Types	Primarily Type I	Type I and Type III
Source	Fish skin and scales	Cow hides and bones
Best For	Skin hydration, elasticity, fine lines, hair, and nails	Joint, bone, gut health, and muscle recovery
Bioavailability	Very high due to smaller peptide size	High, but slightly less than marine
Absorption Speed	Faster absorption	Slightly slower absorption
Dietary Suitability	Pescatarian-friendly, not suitable for fish allergies	Not suitable for pescatarians or vegetarians
Common Side Effects	Mild digestive upset, fishy aftertaste (rare)	Mild digestive upset (rare)

Potential Side Effects and Considerations

When combining supplements, the total dosage is an important consideration. While both marine and bovine collagen are generally well-tolerated, excessive intake could potentially lead to mild digestive issues such as bloating or stomach discomfort. It is essential to adhere to the recommended dosage on the product labels and to start with smaller amounts if you are new to collagen supplementation. For most people, a daily intake of 10-30 grams of combined collagen is considered safe and effective.

Allergic reactions are another factor to consider. If you have a fish or shellfish allergy, marine collagen is not a suitable option. Similarly, those with beef sensitivities or who follow a pescatarian or vegetarian diet should stick to marine collagen or plant-based alternatives. As with any new supplement, it's wise to consult a healthcare professional, especially if you have existing health conditions or are taking other medications.

Lists of Benefits from Combining Collagens

Comprehensive Skin Support: Marine collagen works on skin elasticity and hydration, while bovine supports skin firmness and structure by providing both type I and III collagen.
Enhanced Joint Health: While bovine collagen supports the cartilage and joints, marine collagen's anti-inflammatory properties can aid in reducing joint discomfort.
Improved Gut Integrity: The combination of type I and type III collagen from bovine sources is highly beneficial for strengthening the intestinal lining and supporting a healthy gut.
Balanced Amino Acid Profile: Combining the two sources provides a wider range of amino acids, which more closely mirrors the body's natural collagen composition and supports overall wellness.
Increased Bone Density: Both marine and bovine collagen contribute to bone strength, with bovine supporting the bone matrix and marine potentially stimulating osteoblast activity for stronger bones.

Conclusion

To conclude, incorporating both marine and bovine collagen into your daily regimen is not only safe but also a highly effective strategy for achieving broader health and beauty benefits. By leveraging the complementary strengths of each source, you can provide comprehensive support for your skin, joints, bones, and gut health. Always prioritize high-quality, hydrolyzed supplements, and be mindful of your total dosage to avoid any potential side effects. Whether you combine them in your morning routine or split them throughout the day, consistency is the ultimate key to success. This powerful combination offers a synergistic approach to wellness, delivering the advantages of both sources for maximum results.
