Why Collagen Works: The Science Behind Glowing Skin, Strong Hair & Healthy Joints

Collagen has become one of the most talked-about ingredients in the world of natural health and beauty — and for good reason. Often referred to as the "glue" that holds our body together, collagen is the most abundant protein in the human body and plays a vital role in maintaining skin elasticity, joint flexibility, gut integrity, and overall strength. But what exactly is collagen, and why are collagen supplements becoming a daily ritual for so many Australians?

In this article, we’ll unpack the science behind collagen, its health benefits, and how you can use it to support your skin, hair, nails, joints, and more.

What is Collagen?

Collagen is a structural protein found in connective tissues such as skin, cartilage, tendons, ligaments, and bones. It makes up about one-third of the body’s protein content and is crucial for maintaining the strength and elasticity of tissues.

There are at least 28 types of collagen, but the three most common types are:

• Type I – Found in skin, tendons, ligaments, and bones. This is the most abundant form and is key to skin health.

• Type II – Found in cartilage and important for joint health.

• Type III – Found alongside Type I in skin and organs, supporting elasticity and firmness.

As we age, our body’s natural collagen production begins to decline — often from our mid-20s — leading to visible signs of ageing such as wrinkles, sagging skin, and joint stiffness.

How Do Collagen Supplements Work?

Collagen supplements contain hydrolysed collagen peptides — short chains of amino acids that are easier for the body to absorb.

Once ingested, these peptides are absorbed through the small intestine and transported via the bloodstream to target tissues, where they help stimulate fibroblasts (collagen-producing cells) and support the regeneration of collagen and elastin.

Studies show that taking collagen supplements consistently for 8–12 weeks can significantly improve skin hydration, reduce wrinkles, and increase skin elasticity. Benefits for joints, nails, and hair are also well-documented.

Benefits of Collagen Supplementation

1. Skin Health and Anti-Ageing

Improves skin hydration and elasticity

Reduces fine lines and wrinkles

Supports skin firmness and structure

2. Hair and Nail Support

Encourages stronger, shinier hair

Reduces nail brittleness and promotes faster growth

3. Joint and Bone Health

Supports cartilage regeneration

Reduces joint pain and stiffness

May improve mobility in active and ageing individuals

4. Gut Health

Supports the integrity of the gut lining

Can help reduce symptoms of leaky gut and digestive discomfort

5. Muscle Recovery and Lean Body Mass

Collagen provides glycine and proline, amino acids critical for tissue repair

Choosing a Quality Collagen Supplement

Not all collagen supplements are created equal. When choosing a product, consider the following:

Hydrolysed for absorption – Look for collagen that’s broken down into peptides

Vitamin C & Zinc – These nutrients help stimulate collagen production

Clean ingredients – No fillers, artificial additives or GMOs

Type of collagen – Consider whether it's marine, bovine, or a specific blend for your goals

How to Take Collagen for Best Results

For best results, collagen should be taken daily, ideally with food. Since collagen is a protein, it’s best absorbed when the body is in a fed state. You can mix it into smoothies, coffee, yoghurt, or even soups.

Dosage Tip: Most studies show results from 2.5g–10g per day.

Combine with Vitamin C: Vitamin C is essential for collagen formation, so pairing your collagen with wholefoods or supplements containing vitamin C (like oranges, kiwi, or super greens) boosts its effectiveness.

FAQ: Collagen Supplements & Products

Is collagen safe? Yes, hydrolysed collagen is well-tolerated by most people with minimal side effects. It’s a natural protein already found in the body.

When will I see results? Visible results often begin after 4–6 weeks of daily use, with best results seen after 8–12 weeks.

Can I take collagen if I’m pregnant or breastfeeding? Always consult your healthcare professional, but most collagen supplements are considered safe during these stages.

What makes a good collagen product? Look for hydrolysed collagen with added Vitamin C or Zinc. Many quality brands offer marine and bovine options, including collagen powders tailored to skin and beauty.

Where can I buy high-quality collagen? You can find a curated selection of premium collagen supplements at Eco Traders, including blends that support skin, hair, nails, and joint health.

Final Thoughts

Collagen supplementation is one of the simplest and most effective ways to support your body’s natural ageing process. Whether your goal is glowing skin, stronger nails, or better joint comfort, the right collagen product can help you nourish your beauty and wellness from the inside out.

By understanding the science behind how collagen works — and why it declines as we age — you’re empowered to take informed steps that support long-term vitality and visible results.
