Marine vs. Bovine Collagen — Which One Is Best?

If you're choosing a collagen supplement, you’ve likely come across two main types:

  • Marine Collagen (from fish)
  • Bovine Collagen (from grass-fed cows)

Which one is better? Let’s break it down.


🐟 Marine Collagen

  • Source: Fish skin and scales
  • Type: Primarily Type I
  • Benefits: Great for skin, fast absorption
  • Best for: Pesco-vegetarians, beauty-focused goals
  • Downside: Can be pricier, fishy taste if unflavored

🐄 Bovine Collagen (Glow+)

  • Source: Grass-fed cow hides
  • Type: Type I & III
  • Benefits:
    • Skin + joints + gut + bones
    • Affordable and versatile
  • Best for: Overall wellness, active adults
  • Bonus: Welnel Glow+ is unflavored and odorless

🧪 Which One Absorbs Better?

Both are hydrolyzed, meaning broken down for better absorption. Bovine offers more complete body benefits, while marine is ideal for beauty-only goals.


✅ Verdict: Why We Chose Bovine

Glow+ is made with bovine collagen peptides, enriched with:

  • Hyaluronic Acid
  • MSM
  • Vitamin C

A well-rounded formula for skin, hair, joints, and beyond.
