Difference between marine vs bovine

Our Marine vs. Bovine Collagen Comparison

  1. Source and Type of Collagen
  • Bovine Collagen: Comes from cows (often skin, bones, or cartilage). It primarily contains Type I and Type III collagen, which are excellent for skin, bones, and joints.
  • Fish Collagen (Marine): Derived from fish scales or skin. It mainly contains Type I collagen, the most abundant type in the body, responsible for skin health and anti-aging benefits.

Since Type I collagen is the most bioavailable and crucial for skin structure, marine collagen is often seen as superior for beauty benefits.

  1. Absorption and Bioavailability

  • Marine Collagen has a smaller molecular size (4,000 Daltons in Crushed Tonic's marine collagen compared to 5,000 Daltons for bovine).

    • Smaller peptides = faster and better absorption.
    • This makes marine collagen particularly effective for skin health and anti-aging.

  • Bovine Collagen is still very effective, but it absorbs slightly slower because the peptides are larger.

  1. Health Benefits

  • Marine Collagen:

    • Better for skin hydration, elasticity, and reducing wrinkles.
    • Popular for beauty-focused results (hair, skin, nails).
    • Also supports bone density and joints.

  • Bovine Collagen:

    • Excellent for joint health, gut support, and general body repair.
    • Combines Type I and III, making it great for tissues, muscles, and bones.
  1. Price Difference
    Marine collagen is more expensive because:
  2. Fish-derived collagen production is more costly.
  3. It’s generally considered purer and less likely to cause inflammation or allergy compared to bovine.
  4. It offers superior absorption and beauty benefits, which increases demand.
  1. Purity and Sourcing

  • Crushed Tonic’s marine collagen is:

    • Tested for zero heavy metals (a risk in some fish sources).
    • Kosher and halal certified, making it suitable for more consumers.

  • Crushed Tonic’s bovine collagen is also high-quality:

    • Free from growth hormones, antibiotics, BSE, and TSE.

Which is Better?

  • If your main focus is skin, hair, and nails, marine collagen may be worth the extra investment because of its superior absorption and Type I concentration.
  • If you’re looking for overall health benefits, such as joint and gut support, bovine collagen is excellent and cost-effective.
Feature Marine Collagen Bovine Collagen
Source Wild-caught fish skin and scales Grass-fed, pasture-raised cow hides
Molecular Size ~4,000 Daltons (smaller, faster absorption) ~5,000 Daltons (slightly harder to absorb, but still easier to absorb than other bovine collagens which are 9,000 Daltons)
Key Benefits - Skin hydration, elasticity, and anti-aging
- Hair and nail strengthening		 - Joint, bone, and muscle health
- Gut health and workout recovery
Absorption Higher bioavailability due to smaller molecules High bioavailability, slightly larger molecules
Certifications Halal, kosher, tested for heavy metals Free from hormones, antibiotics, BSE, TSE, and other impurities
Sustainability Eco-friendly, uses discarded parts of fish Ethically sourced from high-quality cattle
Flavor Profile Flavorless Flavorless, a little bit "saltier" tasting
Best For Beauty: Skin, hair, and nails Overall wellness: Joints, gut, and recovery, but still relevant for beauty
