Collagen & Longevity: How to Choose the Best Collagen for Healthy Ageing
By Eryn Behan – Founder of NEE-V
For years, collagen has been positioned primarily as a beauty supplement.
But the conversation around collagen is changing.
As longevity and healthy ageing become two of the biggest movements in wellness, we're becoming less interested in simply looking younger and much more interested in supporting how we feel, move and age over time.
And that raises an interesting question:
What role does collagen actually play in longevity, and how do you choose the best collagen supplement for your body?
Collagen Is About More Than Beauty
Collagen is the body's most abundant protein and provides structural support throughout the body, including the skin, bones, tendons and connective tissues.
This is why collagen has moved beyond the beauty aisle and into the broader healthy ageing conversation.
For women in particular, this becomes increasingly relevant as we age.
Natural collagen production declines with age, with particularly significant changes occurring around menopause.

For me, that's why collagen isn't about anti-ageing.
It's about healthy ageing.
So, What Is the Best Collagen for Healthy Ageing?
This is where things can become confusing.
Search for the best collagen supplement in Australia and you'll find marine collagen, bovine collagen, powders, liquids, gummies, high-dose formulations and products containing long lists of additional ingredients.
But more isn't necessarily better.
When choosing collagen, I look at four things:
| What to look for | Why it matters |
|---|---|
| Clinically researched collagen peptides | Look beyond the word "collagen" and ask whether the specific peptides have human clinical research behind them. |
| An evidence-based daily serving | More collagen isn't automatically better. The relevant question is whether the dose reflects the research behind the ingredient. |
| Ingredient transparency | Know exactly what you're taking and why every ingredient is there. |
| A format you'll actually take | Marine or bovine, flavoured or unflavoured, the best collagen is ultimately one you can take consistently. |

Marine vs Bovine Collagen: Which Is Better?
This is another question I hear constantly.
The truth is, marine collagen and bovine collagen can both have a place in a healthy ageing routine.
Rather than assuming one source is universally superior, look at the specific collagen peptides, their research, the formulation and what you're hoping to support.
Marine collagen can be a great option for people who prefer a marine source and want a clean, simple collagen as part of their skin health routine.
Bovine collagen is another widely used source and can provide bioactive collagen peptides with specific clinical research behind them that not only supports skin health and structure but intestinal health also.
At NEE-V, we offer both because wellness isn't one-size-fits-all.

What About Collagen for Skin?
This is where the evidence becomes particularly interesting.
Specific bioactive collagen peptides have been studied for their effects on skin elasticity, hydration and the appearance of wrinkles.
And importantly, dose matters differently depending on the ingredient being studied.
A product containing 10 or 20 grams of generic collagen isn't automatically superior to a smaller serving of a specific clinically researched peptide.
That's an important distinction when comparing collagen powders in Australia because the biggest number on the label doesn't necessarily tell you which product has the strongest evidence for your goal.

Collagen and Gut Health
Another increasingly popular search is collagen for gut health.
Research into collagen and gut health is still developing, and I think brands need to be careful about overstating what we know.
Collagen provides amino acids, including glycine, but that doesn't mean we should market collagen as a cure for bloating or digestive problems.
Instead, I see collagen as one component of a broader nutrition and wellness routine.
A diverse diet, fibre, hydration, movement, sleep and looking after your gut microbiome all matter.

Flavoured or Unflavoured Collagen?
There's no scientifically superior answer here.
The best option is the one that fits naturally into your routine.
Some people want an unflavoured collagen powder they can add to coffee, water or smoothies.
Others prefer a flavoured collagen that becomes a daily ritual they genuinely enjoy.
Consistency matters more than making your routine unnecessarily complicated.
It's exactly why NEE-V offers both.
Where Does Collagen Fit Into Longevity?
This is where I believe the conversation is heading next.
Longevity isn't simply about adding years to your life.
Increasingly, we're talking about healthspan: staying strong, mobile, independent and well for as much of our lives as possible.
Collagen isn't a magic longevity supplement and there isn't evidence that taking collagen makes you live longer.
But collagen is a major structural protein in tissues that change as we age.
That's why I believe it belongs within a much broader conversation about healthy ageing alongside:
Strength training.
Adequate protein.
Movement.
Sleep.
Nutrition.
Gut health.
Sun protection.
And evidence-based supplementation.
The Next Generation of Wellness
This is also where things are becoming particularly exciting for me personally.
I've never wanted NEE-V to simply be another collagen brand.
NEE-V began with skin health and beauty from within, but my vision has always been broader: helping people make simple, evidence-based choices that support how they look, feel and age.
And that means looking beyond collagen.
Behind the scenes, we're currently developing something new in the cellular wellness and longevity space.
I can't reveal too much just yet.
But it's designed around something I believe will become increasingly important in the conversation around strength, vitality and healthy ageing.
The next chapter of NEE-V is coming.
Final Thoughts
So, what is the best collagen supplement?
I don't think the answer is necessarily marine versus bovine.
Flavoured versus unflavoured.
Or even the product containing the most grams of collagen.
Look for quality.
Look for transparency.
Look for clinically researched ingredients.
Look for a formulation that aligns with what you're trying to achieve.
And most importantly, choose something you can consistently make part of your life.
Because whether we're talking about collagen, movement, nutrition or longevity, healthy ageing is rarely built through one dramatic intervention.
It's built through the small things we choose to do every day.

Frequently Asked Questions
What is the best collagen supplement in Australia?
The best collagen supplement depends on your individual goals. Look beyond the total grams of collagen and consider whether the product contains clinically researched collagen peptides at an evidence-based dose, has transparent ingredients and is easy to take consistently. Both marine and bovine collagen can form part of a healthy ageing routine.
Is marine collagen or bovine collagen better?
Neither marine nor bovine collagen is automatically better. The source matters, but so do the specific collagen peptides, clinical research, formulation and intended benefit. Marine collagen may suit those who prefer a marine source, while bovine collagen can provide clinically researched bioactive peptides such as VERISOL®.
What is the best collagen for women over 40?
As natural collagen production declines with age, particularly around menopause, women over 40 may want to look for clinically researched collagen peptides designed to support skin elasticity, hydration and firmness. Consistency, an evidence-based serving and overall lifestyle are more important than simply choosing the product with the highest number of grams.
Is collagen good for longevity?
Collagen hasn't been shown to extend lifespan and shouldn't be considered a magic longevity supplement. However, collagen is an important structural protein found throughout the skin, bones, tendons and connective tissues. Supporting these tissues can form part of a broader healthy ageing approach alongside strength training, nutrition, sleep and regular movement.
What is the best collagen for skin?
For skin health, look for collagen peptides that have been specifically studied in human clinical trials for outcomes such as skin elasticity, hydration and wrinkles. VERISOL® bioactive collagen peptides, used in NEE-V formulations, have been specifically researched for skin health.
Is collagen good for gut health?
Research into collagen and gut health is still developing. Collagen provides amino acids including glycine, but it shouldn't be viewed as a treatment for bloating or digestive conditions. Gut health is best supported through a broader approach including a varied diet, fibre, hydration, movement and quality sleep.
Is unflavoured collagen better than flavoured collagen?
Not necessarily. An unflavoured collagen powder can be convenient for adding to coffee, smoothies or water, while a flavoured collagen can make a daily routine more enjoyable. What's most important is the quality of the formulation and choosing something you'll take consistently.
How much collagen should I take each day?
The appropriate amount depends on the specific collagen ingredient and the outcome it has been studied for. More isn't automatically better. Some clinically researched bioactive collagen peptides have demonstrated benefits at relatively small daily servings, so it's important to follow the recommended serving for the specific product.
Does collagen help during menopause?
Collagen isn't a treatment for menopause, but declining oestrogen is associated with significant changes in skin collagen. Clinically researched collagen peptides may help support skin hydration, elasticity and firmness as part of a broader healthy ageing routine during and after menopause.
What should I look for when buying collagen powder?
Look for a clearly identified collagen source, clinically researched peptides where relevant, an evidence-based serving, transparent ingredients and a formulation without unnecessary additions. Whether you choose marine or bovine, flavoured or unflavoured, the best collagen powder is ultimately one that matches your goals and that you can take consistently.
