Quick answer: The best collagen in NZ is one that matches your goal (skin, joints, gut support), uses hydrolysed collagen peptides, clearly states the collagen type and daily serve in grams, keeps ingredients simple, and fits your preferences such as bovine vs marine, flavour, and capsule vs powder.

Collagen is the most abundant protein in the body and a popular supplement for skin, joints, and everyday ageing support. In this guide, we walk through what to look for when shopping for collagen in New Zealand, how to take it, and what to watch for.

What collagen is and what it does

Collagen is a structural protein found in skin, cartilage, tendons, ligaments, and bone. As we age, collagen production naturally declines. Collagen supplements usually provide hydrolysed collagen peptides, meaning the protein is broken into smaller pieces that are easier to dissolve and digest.

Most people take collagen for one or more of these reasons:

Skin support such as hydration and elasticity

Joint and connective tissue support for active lifestyles

Protein top-ups when dietary protein is low

How to choose the best collagen in NZ

There is no single perfect product for everyone. We recommend choosing based on ingredient quality, dose, and how you will actually use it day to day.

1) Pick the collagen type that suits you

Bovine collagen is commonly rich in Type I and Type III collagen and is often chosen for skin and general support.

Marine collagen is sourced from fish and is often marketed for skin support. It can be a good option if you prefer fish-based ingredients.

Multi-collagen blends may combine types, but check the label for actual grams per serve.

2) Check the daily serve in grams

Many studies on collagen peptides use gram-level doses. Look for a label that clearly states grams of collagen peptides per daily serve. If a product is in capsules, make sure the total daily collagen amount adds up to your target.

Prefer a simple powder you can add to drinks or recipes? Our Raw collagen powder is designed for easy daily mixing.

3) Look for hydrolysed collagen peptides

Hydrolysed collagen peptides dissolve more easily and are the form most commonly studied. Avoid products that do not specify the form or that rely mainly on fillers and flavours.

4) Keep the ingredient list simple

If you have sensitivities, choose formulas with minimal extras such as sweeteners, gums, or added herbs. If you want capsules for convenience, choose a product that is clear about what is in the capsule shell and what else is included.

For an easy capsule option, see our Collagen infusion capsules.

5) Check quality signals

Clear country of origin and manufacturer details

Batching, traceability, and good manufacturing practices

Third-party testing or transparent quality statements where available

A quick checklist for comparing collagen products

Use this list when you are scanning labels online or in store.

Goal fit: skin, joints, training recovery support, or general protein top-up

Source: bovine or marine, plus any relevant allergy notes

Form: hydrolysed peptides for easy mixing and digestion

Dose clarity: grams of collagen per daily serve, not just per scoop or per capsule

Ingredients: minimal extras, clear allergens, no hidden blends

Value: cost per gram per day, not just cost per tub

Quality: traceability, manufacturing standards, and any testing statements

How much collagen should you take?

There is no single official dose for everyone, and needs vary based on diet and your reasons for supplementing. Research commonly uses collagen peptide doses in the range of a few grams up to around 10 grams per day, depending on the outcome being studied.

We recommend starting with the label directions, choosing a dose you can take daily, and adjusting only if it suits you and your budget. If you have specific health goals, consider talking with a professional who can factor in your diet and training.

Tips to make collagen easier to use every day

Make it part of something you already do

Habit beats willpower. If you already have a morning coffee, smoothie, or yoghurt, that is often the easiest place to add collagen powder. If you travel a lot, capsules can be more practical.

Mixability matters

If you dislike clumps, mix powder into a small amount of liquid first, stir, then top up. Warm liquids can help some powders dissolve faster, but always follow storage and preparation guidance on your product.

Food ideas

Stir into oats, chia pudding, or yoghurt

Blend into a smoothie with fruit and greens

Add to baking where the flavour is neutral, such as muffins or protein balls

How to judge value for money in NZ

Price tags can be misleading because serving sizes vary. The simplest comparison is cost per daily collagen gram.

1. Find the grams of collagen per serve on the label.

2. Check how many serves are in the pack.

3. Estimate the total grams of collagen in the pack, then divide the price by total grams.

This makes it easier to compare powders and capsules side by side.

Powder vs capsules: which is better?

Both can work well. The best choice is the one you can take consistently.

Powder is usually the easiest way to reach a higher gram dose and can be mixed into coffee, smoothies, yoghurt, or baking.

Capsules are convenient for travel and routine, but may require more capsules to reach a comparable collagen dose.

How to take collagen for best results

Choose a routine you will stick to

Daily consistency matters more than the time of day. Many people take collagen with breakfast, in a coffee, or after training.

Pair it with a balanced diet

Collagen is a protein, but it is not a complete protein by itself. Aim for overall protein intake from foods such as meat, fish, eggs, legumes, and dairy. Vitamin C also supports normal collagen formation, so include fruit and veg like kiwifruit, capsicum, broccoli, and citrus.

Be patient

Collagen is not a quick fix. If you are tracking changes such as skin feel or joint comfort, give your routine time and reassess after several weeks.

Potential side effects and who should be cautious

Collagen supplements are generally well tolerated, but some people report mild digestive upset, a lingering taste, or feelings of fullness. You should be extra cautious if you:

Have a fish allergy and are considering marine collagen

Have known sensitivities to flavours, sweeteners, or additives

Are pregnant or breastfeeding, or taking prescription medicines and want personalised advice

If you have a medical condition or you are unsure, we recommend checking with a qualified health professional.
