A naturopath’s buying guide
How to choose the best collagen supplement — a naturopath’s guide.
Comparing collagen powders and not sure what actually matters? Five things separate a genuinely good supplement from a pretty label: the collagen type, whether it’s hydrolysed for absorption, a meaningful dose, the cofactors that let your body use it, and who formulated it. Here’s the criteria — from Angela Maree Smith, clinical naturopath and Director of the Melbourne Natural Medicine Clinic.

The checklist
The 6 things that separate the best collagen supplements.
Most collagen powders look identical on the shelf. They aren’t. Run any supplement you’re considering — including this one — through these six criteria before you buy.
The collagen type
For skin you want Type I — the collagen most abundant in skin. “Multi-type” blends are often aimed at joints and gut, not radiance.
Hydrolysed for absorption
Look for “hydrolysed” collagen peptides — broken into low-molecular-weight fragments your body can actually absorb. Intact collagen mostly passes through.
A meaningful dose
Under-dosed powders are the most common let-down. A serve should deliver a clinically-relevant amount of peptides, not a sprinkle for the label.
Cofactors that make it work
Collagen alone isn’t enough. Vitamin C and antioxidants are the cofactors your body needs to synthesise and protect collagen — most powders leave them out.
Clean & certified-organic
Check for certified-organic ingredients, no artificial fillers, sweeteners or colours, and honest allergen disclosure. Quality shows in what’s left out.
Who formulated it
The biggest tell of all. Was it built by a practitioner who treats skin from the inside for a living — or by a marketing team chasing a trend?
Meet your guide
Angela Maree Smith — the naturopath who wrote the criteria.
Angela is a clinical naturopath and Director of the Melbourne Natural Medicine Clinic in South Melbourne — a broadcaster, writer and clinical presenter to other naturopaths, and an industry advisor on nutritional and herbal formulations, influencing what many health-care practitioners prescribe today. The six criteria above aren’t marketing — they’re how a practitioner assesses a formula.
A collagen worth buying is clinical-strength and cofactor-complete — not a single ingredient with fairy dust.
Marine vs bovine collagen
Which type of collagen is best — for what?
The first fork in choosing a collagen. Both are ingestible collagen — but the right source depends on your goal. For skin specifically, hydrolysed Type I marine collagen is the source most researched for elasticity, hydration and the look of wrinkles.
What about collagen creams? Topical collagen molecules are too large to absorb through skin — if skin is your goal, hydrolysed marine peptides work from within, inside-out.
The best-collagen scorecard
What to look for — and who actually passes.
The same six criteria as a checklist. This is where most single-ingredient powders fall down — and where a naturopath-formulated system holds up.

Why most collagen powders underdeliver
A scoop of plain collagen was never going to do it.
If you’ve tried collagen and felt nothing, it probably failed the checklist. Most powders are one ingredient with a pretty label — collagen on its own lacks the cofactors your body needs to actually put it to work in the skin, which is why so many women try it, feel nothing, and quietly give up.
One ingredient, no synergy
Plain collagen lacks the vitamin C, antioxidant and nutrient cofactors that skin needs to synthesise and protect collagen.
Marketing, not formulation
Trend-led brands lead with packaging and influencers. Few are formulated by a practitioner who treats skin from the inside for a living.
Under-dosed & poorly paired
If peptides aren’t dosed and paired for bioavailability, most of what you pay for is simply passed through, not used.
What the right collagen supports
Choose well, and here’s what you’re buying.
When a collagen ticks every criterion, this is what it’s for. In clinical research, hydrolysed collagen peptides have been shown to support skin outcomes with consistent daily use. Individual results vary.
Skin elasticity & firmness
May help support the skin’s own collagen and elasticity for a smoother, firmer look over time.
The look of fine lines & wrinkles
Supports skin hydration and density — helping soften the appearance of fine lines with ongoing use.
Beauty from within
Marine collagen paired with certified-organic superfoods makes a considered daily ritual for women investing in their skin from the inside out.
Hydration & radiance
Antioxidant cofactors help skin retain moisture and glow, and protect against everyday oxidative stress.

What should I look for in a collagen supplement?
Five things: the collagen type (Type I for skin), whether it’s hydrolysed into small, absorbable peptides, a meaningful dose, the cofactors that let your body use it (vitamin C and antioxidants), and who formulated it. A supplement that ticks all of these — ideally practitioner-formulated and certified-organic — is worth far more than a cheaper single-ingredient powder.
Is marine or bovine collagen better?
It depends on your goal. For skin, hydrolysed Type I marine collagen is the source most researched for elasticity and hydration, and it tends to be more bioavailable. Bovine collagen (Type I & III) is more often chosen for joint and gut goals.
Is a more expensive collagen supplement worth it?
Not automatically — price alone tells you little. What justifies a premium is a genuinely better formula: hydrolysed Type I peptides at a meaningful dose, cofactors that improve how your body uses them, certified-organic ingredients, no fillers, and practitioner formulation. A cheap powder that’s under-dosed and cofactor-free is the more expensive option if it does nothing.
How can you tell if a collagen supplement is good quality?
Read past the front of the pack. Look for the words “hydrolysed” and the collagen type, a stated serve size and peptide amount, added cofactors like vitamin C and antioxidants, certified-organic ingredients, honest allergen disclosure, and a named formulator with real credentials. Quality shows as much in what’s left out (fillers, artificial colours, sweeteners) as what’s in.
Does the collagen type matter (Type I vs Type III)?
Yes. Type I is the collagen most abundant in skin, so it’s the type you want for skin goals. Type III often accompanies Type I in bovine blends and is associated more with structural and gut tissue. Marine collagen is predominantly Type I, which is why it’s favoured for skin.
Why do cofactors like vitamin C matter?
Your body can’t synthesise or protect collagen on vitamin C-free autopilot — vitamin C is a required cofactor, and antioxidants help defend collagen against everyday oxidative stress. A collagen powder with no cofactors gives your body the raw material but not the tools to use it well, which is why single-ingredient powders so often disappoint.
Does a naturopath-formulated collagen actually make a difference?
It’s the clearest quality signal there is. A clinical naturopath who treats skin from the inside for a living formulates for absorption, dose and synergy — not for a trend or a pretty tin. Collagen Ultimate+ is formulated by Angela Maree Smith, clinical naturopath and Director of the Melbourne Natural Medicine Clinic.
How long until I see a difference?
Skin renews gradually. With consistent daily use, hydration and firmness are typically supported from around 4–8 weeks, with more pronounced results at 8–12 weeks — which is exactly why Subscribe & Save exists. Individual results vary.
