Do Collagen Supplements Really Work? Evidence & Science (2026 Update)

Last updated: January 2026

It’s clear that collagen supplements are everywhere right now but as to whether they actually work, is still a little inconclusive. While they sound great in theory, can taking a bit of powder each morning really result in collagen enhancement that gives an improved complexion? Below, we consult NEE-V’s founder Eryn Behan on whether collagen supplements actually work (for all the things they say it does).

FIRSTLY, WHAT IS COLLAGEN?

In simple terms, collagen is a thing that is already in our bodies, it makes up a big part of our skin and is also a crucial component of the human body’s joints, bones, muscles, ligaments, tendons, hair and nails. Collagen is actually the most abundant protein in the human body, making up about 30% of our body protein. If we look at it in more detail, it’s a fibre-like structure that is used to make connective tissue. What’s more, it’s also in our blood vessels, intervertebral discs, the blood-brain barrier, the cornea, dentin and the intestinal wall, it really is a vital component of our whole body.

IF IT’S ALREADY IN OUR BODIES, WHY DO WE NEED TO SUPPLEMENT IT?

In short – as we age, our bodies start producing less collagen (life can be cruel can’t it?!). This unfortunate truth starts happening usually once we reach the 25 - 30 years of age mark. At this age, the body starts slowing down collagen production over time and the older we get, the less collagen our bodies produce. The result of this collagen production slow down tends to leave us with thinner and less elastic skin (hello fine lines and wrinkles). Internally, that lack of collagen in our bodies can leave us with stiff joints and gut issues. The good news? Collagen supplements can work towards replenishing this loss of collagen and in turn support the affected areas in our bodies.

BUT DO COLLAGEN SUPPLEMENTS ACTUALLY WORK?

Despite often conflicting information online, they do actually work (but not always). The reason we say not always is that it really just depends on the brand that you’re using (not all collagen supplements are made equal). For example, some “collagen” supplements don’t actually contain collagen, and may contain plant based nutrients instead. While this sounds great in theory, sometimes brands are great at marketing tactics and clever jargon, instead of actually producing a desired result. When choosing a collagen supplement, look for one that has been clinically proven, such as NEE-V collagen Powder. NEE-V Collagen Powder targets skin, hair and nails, but also supports the gut, digestion and joint health because it is made from bovine collagen. Both fish and bovine (beef collagen) have skin benefits so if you were just after improvements in the skin, you could take either collagen. However, to support joint health and the gut, bovine collagen is considered a superior collagen type. NEE-V Collagen Powder is also made from hydrolysed collagen which is a form of collagen that is broken down into smaller protein fragments called amino acids. Collagen peptides are the building blocks of collagen, and they're found in the hydrolysed form. When collagen peptides are broken down into smaller pieces, they become available for use by our body to help with our skin, hair and nail health. Some research shows that our bodies may absorb hydrolysed collagen more efficiently.

Collagen supplements are one of the most popular wellness products in Australia, promoted for benefits ranging from skin hydration and elasticity to joint comfort and healthy ageing. But with so much marketing noise, a key question remains:

Do collagen supplements really work?

In this updated 2026 guide, we look at the scientific evidence behind collagen supplementation, what outcomes are supported by research, where evidence is limited, and how to make an informed choice.

What Is Collagen and Why Does It Decline With Age?

Collagen is the most abundant protein in the human body. It plays a structural role in skin, joints, tendons, ligaments, bones and connective tissue.

From our mid-20s onwards, natural collagen production gradually declines. Factors such as ageing, sun exposure, stress, smoking and poor nutrition can accelerate this process, contributing to visible skin ageing and reduced joint resilience.

This decline is one reason collagen supplements have gained attention as a potential support for skin and musculoskeletal health.

How Do Collagen Supplements Work?

Most collagen supplements contain hydrolysed collagen peptides. These are collagen proteins broken down into smaller amino acid chains to improve digestion and absorption.

After ingestion, collagen peptides are absorbed into the bloodstream and provide amino acids and bioactive peptides that may help stimulate the body’s own collagen production over time. Collagen does not go directly to the skin or joints, but instead supports the body’s natural repair and renewal processes.

Do Collagen Supplements Work in Australia?

For Australians considering collagen as part of their wellness routine, the question is increasingly common: do collagen supplements work in Australia, and is there scientific evidence to support their benefits?

The research behind collagen supplementation is global and applies equally to Australian consumers. Effectiveness depends less on location and more on collagen type, dosage, consistency and overall lifestyle factors.

What Does the Science Say About Collagen Supplements?

Skin Hydration and Elasticity

This is the area with the strongest evidence.

Clinical studies suggest collagen peptide supplementation may improve skin hydration, elasticity and the appearance of fine lines when taken daily for at least 8 to 12 weeks. Improvements are typically gradual and subtle rather than dramatic.

Joint Comfort and Mobility

Moderate evidence suggests collagen supplementation may support joint comfort and function, particularly in physically active individuals and older adults. Benefits appear more likely with consistent use over several months.

Hair and Nails

Evidence here is mixed. While collagen provides amino acids involved in keratin production, results for hair thickness and nail strength vary between individuals and studies.

Gut and Internal Health

Emerging research suggests collagen may support gut lining integrity due to its amino acid profile, but more high-quality research is needed before firm conclusions can be drawn.

Evidence Snapshot: What Collagen Supplements Can Support

Why Results From Collagen Supplements Vary

Not everyone experiences the same results. Factors that influence outcomes include:

• Type and quality of collagen peptides

• Daily dosage and consistency

• Length of use

• Overall protein intake and nutrition

• Lifestyle factors such as sun exposure, sleep and stress

• Age and baseline collagen levels

Consistency matters more than high doses, and collagen works best alongside healthy habits.

Choosing a Collagen Supplement That Aligns With the Science

If you are comparing collagen supplements in Australia, look for:

• Hydrolysed collagen peptides for better absorption

• A clearly stated daily dose

• Transparent ingredients with no unnecessary fillers

• A formulation suitable for long-term, daily use

For those seeking a clinically researched option, NEE-V Ingestible Collagen is formulated with VERISOL® collagen peptides, a patented ingredient studied for its role in supporting skin hydration and elasticity when taken consistently as part of a balanced routine.

Common Myths About Collagen Supplements

Myth: Collagen works instantly
Reality: Most benefits appear after weeks of consistent use.

Myth: Collagen goes straight to the skin
Reality: Collagen supports the body’s overall collagen synthesis processes.

Myth: More collagen means faster results
Reality: Quality, consistency and absorption matter more than excessive dosing.

How Long Does Collagen Take to Work?

Most clinical research measures outcomes after 8 to 12 weeks of daily supplementation. Skin hydration often improves first, followed by elasticity and joint comfort over longer periods.

Are Collagen Supplements Worth Taking?

Based on current evidence, collagen supplements may provide modest but meaningful benefits, particularly for skin hydration and joint comfort, when taken consistently and in appropriate forms.

They are not a miracle solution, but when used as part of a broader wellness routine, collagen supplements can play a supportive role in healthy ageing.
