Collagen has had quite the glow-up in the NZ wellness world. From being a vaguely clinical joint supplement to a full-on beauty and lifestyle product stirred into your morning coffee — it’s everywhere. And for once, the hype isn’t completely disconnected from the science.
But with so many products on the market, how do you know what’s worth your money? Let’s break it down properly.

What Is Collagen and Why Does It Matter?
Collagen is the most abundant protein in your body — making up about 75% of your skin’s structure and around a third of total body protein. It’s the scaffolding that keeps skin plump and firm, joints cushioned, and connective tissues strong. The problem? From around age 25, your body produces about 1% less collagen per year. By your 40s, the effects become visible — thinner skin, more wrinkles, creakier joints, slower recovery.
The good news is that hydrolysed collagen supplements — where the collagen has been broken into smaller peptides for better absorption — have a solid evidence base behind them. A 2023 systematic review of 26 trials published in Nutrients found that taking hydrolysed collagen for eight weeks improved skin hydration and elasticity.
Marine vs Bovine Collagen — What’s the Difference?
| Marine Collagen | Bovine Collagen | |
|---|---|---|
| Source | Fish scales and skin | Cow hide and bones |
| Type | Primarily Type I | Type I and III |
| Bioavailability | Higher — smaller peptide size | Very good |
| Best for | Skin, hair, nails, anti-ageing | Joints, gut, muscle, broader benefits |
| Sustainability | Uses fish by-products | By-product of beef industry |
| Taste | Mild to neutral | Very neutral |
For skin, hair and nails: marine collagen is generally considered superior due to its smaller peptide size and higher absorption rate. For joint and gut health: bovine collagen’s Type I and III combination offers broader benefits. Can’t decide? Some NZ brands now offer blends.

How to Use Collagen for Best Results
Take it daily — consistency is what drives results. Most research uses 2.5–10g of hydrolysed collagen peptides daily. Take it with vitamin C (either combined in the product or alongside it) to support collagen synthesis. Most people notice initial skin hydration improvements within 3–4 weeks; deeper structural changes in skin elasticity take 8–12 weeks. Hair and nail improvements often take longer — give it 3 months.

For skin, hair, and nails: Jeuneora Renew+ is our top pick — NZ-made, B Corp certified, and clinically studied. For a more budget-friendly NZ option: Neat Collagen+ delivers solid quality without the premium price. For joint support and broader collagen benefits: Mitchells Nutrition bovine collagen is the smart choice.
