What is Collagen?
Collagen is the most abundant protein in the human body, making up 30% of total protein. It forms a structural scaffolding that provides strength and elasticity to connective tissues like skin, bones, cartilage, ligaments and tendons.
Collagen production starts declining around age 25, leading to common signs of aging like fine lines, sagging skin, and joint problems. Supplements aim to counteract this by delivering extra collagen.
Understanding the Different Collagen Types
There are at least 16 different types of collagen in the body, but around 90% consists of types I, II, and III. Different collagens serve various functions:
Type I
- Most abundant, making up 70-80% of collagen in the body
- Forms fibrous tissues like tendons, ligaments, bones, skin, GI tract
Type II
- Primary collagen of cartilage
- Helps build strong flexible joints
Type III
- Forms connective tissues along with type I collagen
- Plays a role in skin elasticity
What is Marine Collagen?
Marine collagen, as the name implies, is sourced from fish parts like scales and skin. It typically contains a higher concentration of type I collagen. Marine organisms like fish have similar collagen structures to humans, allowing for better absorption.
Benefits of Marine Collagen
Research indicates marine collagen supplementation may provide perks like:
- Reducing signs of skin aging like wrinkles and dryness
- Improving skin elasticity and moisture retention
- Speeding wound healing
- Relieving joint pain and inflammation
- Strengthening nails and hair
Marine Collagen Sources
Fish commonly used for marine collagen include:
- Tilapia
- Salmon
- Cod
- Haddock
- Flounder
Scales, skin, and fins are processed to extract marine collagen powder or liquid supplements.
What are Collagen Peptides?
Collagen peptides, also called hydrolyzed collagen, are derived from collagen-rich animal parts such as hides and bones. The collagen is broken down into small peptides for better absorption.
Benefits of Collagen Peptides
Potential benefits associated with collagen peptides include:
- Increased skin hydration, elasticity, and dermal collagen density
- Reduced joint pain and degeneration
- Building lean muscle mass when combined with exercise
- Accelerated wound healing
- Strengthening nails and hair
Collagen Peptide Sources
Common sources for collagen peptides include:
- Bovine hide and bones
- Porcine hide and bones
- Chicken cartilage
- Eggshell membrane
- Marine fish
Comparing Marine Collagen vs. Collagen Peptides
Marine collagen and collagen peptides share some similarities but also have key differences that impact benefits:
Absorption
- Marine collagen molecules are larger so take longer to digest and absorb.
- Collagen peptides have enhanced bioavailability with up to 90% absorption rate.
Collagen Types
- Marine collagen contains primarily type I collagen.
- Collagen peptides provide a more complete collagen profile with types I, II, III, V and X.
Joint Health
- Marine collagen provides abundant collagen type I for bone and joint stability.
- Collagen peptides additionally supply collagen type II to rebuild cartilage.
Skin Benefits
- Both deliver collagen types I and III to nurture skin elasticity and hydration.
- Peptides may be more quickly utilized for enhanced dermal collagen production.
Muscle Building
- Marine collagen lacks evidence for muscle protein synthesis support.
- Peptides help boost muscle mass gains, especially when paired with exercise.
Bioavailability
- Marine collagen molecules are larger so take longer to digest and absorb.
- Collagen peptides have enhanced bioavailability with up to 90% absorption rate.
Taste
- Marine collagen is relatively tasteless and easily mixes into liquids.
- Collagen peptides have a more distinctive taste and texture.
Cost
- Marine collagen tends to be pricier than collagen peptide supplements.
- Collagen peptides provide cost savings due to sourcing from byproducts.
Which is Better: Marine or Peptide Collagen?
So when it comes down to marine collagen versus peptides, which collagen supplement is the winner? Here's a quick recap:
Choose Marine Collagen If You Want:
- A concentrated type I collagen source
- Fast joint relief
- A mild flavor
- Rich skin hydration
Choose Collagen Peptides If You Want:
- A more complete collagen profile
- Maximum bioavailability
- Muscle building support
- Affordability
Both types of collagen offer proven benefits for common aging concerns like skin changes, brittle nails, hair thinning, and joint discomfort. For a well-rounded approach, a blend may be optimal.
How to Choose a Collagen Supplement
When comparing collagen supplements, keep these tips in mind:
Check the Collagen Source
- Marine collagens should be sustainably sourced from wild fish.
- Look for peptide collagens derived from pasture-raised, hormone-free animals.
Consider Added Ingredients
- Vitamin C may help with collagen absorption.
- Hyaluronic acid, ceramides, coenzyme Q10 provide added skin perks.
Look for Third Party Testing
- Reputable brands validate purity with independent lab testing.
- Ensure no contaminants like heavy metals, pesticides or toxins.
Watch Out for Additives
- Avoid collagen with artificial flavors, sweeteners and preservatives.
- Steer clear of vague ingredient labels.
Read the Label for Dosage
- Aim for 10-20 grams daily for best results.
- Stick with the recommended serving size.
The Takeaway
Both marine collagen and collagen peptides provide scientifically-proven benefits. Marine collagen shines for abundant type I collagen to support skin, hair, nails, bones and joints. Collagen peptides offer highly bioavailable types I and III collagen along with types II, V, and X for comprehensive support.
The collagen supplement you choose can depend on your main concerns. But a safe bet is combining marine and peptide collagen for the best of both worlds. Focus on quality sources and ingredients for optimal outcomes. With the right collagen, you can defy aging and keep your body feeling its best.
FAQs
What is the difference between marine collagen and collagen peptides?
Marine collagen comes from fish and is primarily type I. Collagen peptides come from animal byproducts and contain a blend of collagen types I, II, III, V and X.
Which is better for skin: marine or peptide collagen?
Both support skin health thanks to collagen types I and III. Marine may provide faster hydration while peptides boost long-term dermal collagen density.
Does marine collagen help build muscle?
No, marine collagen does not appear effective for muscle protein synthesis. Collagen peptides do help increase lean muscle mass when combined with exercise.
Is one type of collagen better absorbed?
Yes, collagen peptides have a higher bioavailability around 90-95% thanks to hydrolysis. Marine collagen absorption ranges from 10-40%.
Can you take both marine and peptide collagen?
Yes, combining both marine and peptide collagen supplements can provide complementary benefits.
