If you’ve been searching for collagen, you’ve probably noticed there’s more than one type. You’ll see “Type 1 collagen”, “Type 2 collagen”, “Type 3 collagen”, marine collagen, bovine collagen, collagen peptides… and it can feel like you need a science degree to pick the right one.
You don’t.
This guide breaks down collagen benefits, what Types 1, 2 and 3 actually mean, and how to choose a collagen supplement that fits your goals.
What is collagen?
Collagen is a structural protein found throughout the body. Think of it as part of the “scaffolding” that supports skin, connective tissues, cartilage, bones, and more.
As we age, collagen production naturally changes. That’s one reason collagen supplements have become popular in wellness routines—especially for people focused on skin, joints, and active lifestyles.
Collagen benefits: why people take it
People choose collagen for a few common reasons:
- Skin support (elasticity, hydration, overall appearance)
- Hair and nail support
- Joint comfort and mobility support
- Support for connective tissues (tendons/ligaments) as part of an active routine
- General healthy ageing support
The key is matching the collagen type (and source) to what you’re trying to support.
Collagen Types 1, 2, 3 explained (simple breakdown)
Type 1 collagen: skin, hair, nails, bones
Type 1 collagen is the most abundant collagen in the body. It’s commonly associated with:
- Skin structure and firmness
- Hair and nails
- Bones and connective tissue
If your main goal is beauty-from-within support, Type 1 is often the first place people start with collagen.
Type 2 collagen: joints and cartilage
Type 2 collagen is found primarily in cartilage. It’s commonly chosen by people focused on:
- Joint comfort
- Mobility support
- Active lifestyle wear-and-tear support
If your main goal is joint-focused collagen support, Type 2 is usually the most relevant.
Type 3 collagen: skin + connective tissue support
Type 3 collagen is often found alongside Type 1. It’s commonly associated with:
- Skin structure
- Connective tissues
- Overall tissue support
Many collagen products contain a blend of Type 1 and Type 3, which is why you’ll often see them paired.
Collagen peptides vs “native” collagen: what’s the difference?
You’ll often see collagen sold as:
- Hydrolysed collagen / collagen peptides: collagen broken down into smaller peptides, designed to mix easily and be convenient to use.
- Undenatured (native) collagen (often Type 2): typically used in smaller doses and commonly positioned for joint support.
You don’t need to memorise the terminology—just know that peptides are the common everyday format (especially for skin/hair/nails), while undenatured Type 2 is often a more joint-specific format.
Marine vs bovine collagen: does the source matter?
Yes—mostly in terms of preference, dietary needs, and which types are most prominent.
Marine collagen
- Sourced from fish
- Often rich in Type 1 collagen
- Popular for skin-focused routines
Bovine collagen
- Sourced from cattle
- Often contains Type 1 and Type 3
- Common “all-rounder” option for skin + connective tissue support
If you avoid fish, marine collagen may not be suitable. If you avoid beef, bovine collagen may not be suitable. Always check labels for allergens and sourcing.
How to choose the right collagen for your goal
Here’s a simple decision guide using the keyword you’re here for: collagen.
Choose Type 1 (or a Type 1 + 3 blend) if your goal is:
- Skin support
- Hair and nails
- General connective tissue support
Choose Type 2 if your goal is:
- Joint comfort
- Cartilage support
- Mobility support
Marine collagen if:
- Your focus is skin
- You prefer a fish-based source
Bovine collagen if:
- You want a broader Type 1 + 3 profile
- You want an easy daily “foundation” collagen
How to take collagen (timing, consistency, and what to pair it with)
Consistency matters most
Collagen is typically used daily for best results. Think in terms of weeks, not days.
When to take it
There’s no perfect time. Take collagen when it best fits your routine:
- In the morning (coffee/smoothie)
- With lunch
- In the evening (hot drink)
What to take it with
Many people pair collagen with vitamin C, because vitamin C contributes to normal collagen formation for the normal function of skin, cartilage, bones, and blood vessels.
You can get vitamin C from food (fruit/veg) or from a supplement—just follow label guidance.
Common collagen mistakes to avoid
- Choosing the wrong type for your goal (e.g., wanting joint support but buying a beauty-focused Type 1 product)
- Taking it inconsistently (a scoop once a week won’t do much)
- Expecting overnight results (give it time)
- Ignoring protein intake (collagen is not a complete protein—keep overall diet balanced)
Collagen and Body by Nature Supplements
Body by Nature Supplements focuses on quality, practical wellness support. If you’re adding collagen to your routine, the best approach is simple:
- Pick the type that matches your goal (Type 1/3 for skin; Type 2 for joints)
- Choose a source that suits your diet (marine vs bovine)
- Take it consistently and pair it with a strong nutrition foundation
Final thoughts
The best collagen isn’t “the most expensive” or “the trendiest”—it’s the one that matches what you’re trying to support.
If you want skin, hair and nail support, look for Type 1 (often with Type 3). If you want joint and cartilage support, Type 2 is usually the most targeted choice.
Choose the right collagen, take it consistently, and you’ll get the most out of your routine.
