Marine Collagen vs. Bovine Collagen

When it comes to collagen, the internet is full of “advice,” confusing claims, and skincare influencers swearing by yet another pastel powder.

But what’s actually the difference between marine collagen powder and bovine collagen?

And more importantly, which one should you be taking?

Let’s break it down.

Bovine vs Marine Collagen: What’s the Deal?

Collagen is the most abundant protein in your body. Think of it like your body’s glue; it keeps your skin firm, your joints cushioned, your hair glossy, and your gut lining strong.

But as we age (yep, even in our 20s), our natural collagen production starts slowing down.

Now here’s where things get juicy. Most collagen supplements come from two main sources:

• Bovine collagen (from cow hides and bones)
  
• Marine collagen (from fish skin and scales)

Both offer benefits, but they’re not created equal.

Marine Collagen Powder: The Glow-Up Star ⭐

Let’s talk marine collagen; the ultimate overachiever.

• Sourced from fish (like wild-caught cod), marine collagen is made up mostly of Type 1 and 3 collagen peptides; the same types found in your skin, bones, and tendons.
  
• It has the smallest molecular size, which means your body can absorb it faster and more efficiently than bovine collagen.
  
• Studies show marine collagen has 1.5x higher bioavailability compared to bovine collagen; translation: it works faster and better.

So...What About Bovine Collagen?

Bovine collagen is the OG. It’s widely available and also rich in Type 1 and 3 collagen. But:

• It comes from cow parts (which some people avoid for religious, ethical, or health reasons).
  
• The peptide size is larger, meaning your body takes longer to break it down and absorb it.
  
• Some users report digestive discomfort or a strong aftertaste.

That doesn’t make it bad; just not quite as effective or well-tolerated for everyone.
