Here’s What to Look For in the Best Collagen

With so many collagen supplements on the market, it’s easy to assume they all do the same thing. But the truth is, not all collagen is created equal. Some formulas barely make a difference, while others are backed by research and designed for real results. The key isn’t just taking collagen, it’s also choosing the right type, form, and ingredients to actually support your skin, joints, and overall health.

If you’re spending money on collagen, you want to make sure it’s actually doing something. So, what separates high-quality collagen from an overpriced product? Here’s what you need to know before adding it to your routine.


1. Hydrolysed Collagen (AKA Collagen Peptides) Absorbs Better

Collagen is a large protein, and in its natural state, it’s difficult for the body to absorb. That’s why hydrolysed collagen peptides are the best option, because they have been broken down into smaller amino acids, making them easier for your body to digest and use efficiently.

If your collagen isn’t hydrolysed (or doesn’t mention peptides), it may not be bioavailable enough to deliver noticeable benefits. High-quality collagen supplements always use hydrolysed peptides to ensure maximum absorption.

A good daily dose should be at least 15 g per serving, a strong amount to stimulate collagen production and support skin elasticity, hydration, and overall resilience, while also strengthening hair, nails, and joints.


2. The Type of Collagen Matters More Than You Think

The best collagen isn’t all the same; there are different types, each serving a unique function in the body:

  • Type I – The most abundant, found in skin, hair, nails, and bones. It helps maintain skin firmness, elasticity, and hydration.

  • Type II – Primarily found in cartilage and joints. It’s essential for mobility and flexibility.

  • Type III – Works alongside Type I and is particularly beneficial for skin elasticity and overall tissue strength.

If you’re looking for anti-ageing benefits, go for Type I and III. For joint health, make sure your supplement includes Type II collagen.

The best collagen supplements contain a blend of all three types to support skin, joints, and connective tissues from multiple angles.


3. Collagen Source: Bovine, Marine, or Chicken?

The source of collagen affects its quality and effectiveness. The three most common sources are:

  • Bovine Collagen (From Cows)

    • Contains Type I and III collagen, which are great for skin, hair, nails, and bones.

    • Grass-fed, pasture-raised sources tend to be higher quality.

    • Provides a well-rounded, all-purpose collagen supplement.

  • Marine Collagen (From Fish)

    • Primarily Type I collagen, making it ideal for skin elasticity and hydration.

    • Considered the most bioavailable form, meaning it’s absorbed faster than other types of collagen.

    • Typically more expensive but excellent for beauty-focused benefits.

  • Chicken Collagen

    • Mainly Type II collagen, making it best for joint support.

    • Often found in joint health supplements rather than beauty-focused ones.

If skin health is your main goal, marine and bovine collagen is an excellent option. If you want a multi-purpose collagen, bovine top collagen works well.


4. Does Your Collagen Have Vitamin C? If Not, It’s Less Effective

Collagen production depends on Vitamin C. Without it, your body can’t properly synthesize collagen, meaning even the best supplement won’t be as effective.

Some high-quality top collagen powders already include Vitamin C, but if yours doesn’t, consider taking it separately to maximize absorption.

A good formula should contain at least 250 mg of Vitamin C per serving to support collagen production, immune function, and antioxidant protection.


5. Key Ingredients That Boost Collagen Absorption

Collagen works best when paired with supportive nutrients that enhance its benefits:

  • Hyaluronic Acid – Helps skin retain moisture, keeping it hydrated and plump. Also supports joint lubrication.

  • Biotin – Strengthens hair and nails while supporting healthy skin.

  • Keratin – A natural protein that improves hair elasticity and resilience.

  • Nicotinamide Riboside (NR) – A key ingredient that supports cellular repair and boosts NAD+ levels for long-term skin and metabolic health.

  • L-Glutathione - A powerful antioxidant that helps brighten skin and fight oxidative stress.

A well-rounded top collagen supplement doesn’t just supply protein, it also provides the building blocks for healthy ageing.


6. Watch Out for Artificial Additives and Fillers

Some collagen products contain unnecessary artificial sweeteners, preservatives, and fillers that provide no actual health benefits. A clean formula should be:

  • Non-GMO

  • Free from artificial sweeteners

  • Gluten-free and dairy-free

  • Third-party tested for purity

A clean, research-backed formula ensures maximum effectiveness without unnecessary additives.


7. How Long Does It Take for Collagen to Work?

Top collagen isn’t an overnight fix. With consistent use, here’s what to expect:

  • 4 weeks – Improved skin hydration and a healthier glow.

  • 8–12 weeks – Smoother, firmer skin, stronger nails, and noticeable hair growth.

  • 3–6 months – Visible reduction in fine lines, better joint mobility, and long-term collagen support.


How to Get the Most Out of Your Collagen Supplement

To maximise collagen benefits:

  • Take it daily—consistency leads to better results.

  • Pair it with Vitamin C—this ensures proper absorption.

  • Stay hydrated—collagen needs water to work effectively.

  • Eat a balanced diet rich in protein and antioxidants for added support.
