TL;DR
Collagen is one of the most abundant proteins in the human body, helping maintain skin elasticity, joint comfort, and healthy hair growth. As we age, natural collagen production declines but research shows that high-quality hydrolysed collagen supplements (particularly marine collagen) can help support firmness, hydration, and mobility.
What is collagen?
Collagen is the main structural protein that holds our body together - think of it as the “glue” that supports skin, bones, joints, tendons, ligaments, and even hair follicles.
Our bodies naturally produce collagen, but starting in our mid-to-late 20s, production begins to drop by about 1% each year. This leads to visible signs of ageing (like fine lines and wrinkles), as well as stiffness in joints and slower recovery after exercise.
How collagen supports skin, joints, and hair
| Function | What collagen does | Benefits you may notice |
|---|---|---|
| Skin | Provides structure and elasticity | Fewer fine lines, smoother texture, improved firmness |
| Joints & bones | Cushions cartilage and connective tissue | Better flexibility, less stiffness after activity |
| Hair & nails | Supports keratin production and scalp structure |
Stronger nails, thicker-looking hair |
Factors that reduce natural collagen levels
1. Ageing
As we age, the fibroblasts in our skin (which produce collagen) slow down. This is why collagen supplements can be beneficial from your late 20s onward.
2. UV exposure
Australia’s strong UV rays can accelerate collagen breakdown. Chronic sun exposure is one of the biggest contributors to premature ageing and pigmentation.
3. Lifestyle and stress
Smoking, excess alcohol, stress, and a low-protein diet can all inhibit collagen synthesis. On the other hand, regular exercise and a diet rich in vitamin C, zinc, and amino acids can support natural collagen production.
Is collagen worth it for skin?
Several clinical studies have shown that oral hydrolysed collagen peptides can improve hydration, elasticity, and dermal density within 8–12 weeks of consistent use.
For example, a 2019 study published in the National Library of Medicine found that participants taking daily collagen experienced measurable improvements in skin firmness and elasticity, compared to those on a placebo.
Key takeaway
If you’re looking to smooth fine lines and boost skin glow from within, collagen supplementation can be worth it, especially when paired with a balanced diet and sunscreen protection.
What about collagen for joints and recovery?
Type II collagen is the form found in cartilage, the connective tissue that cushions your joints. As collagen production slows, cartilage thins, increasing joint stiffness and post-exercise soreness.
Clinical evidence suggests that collagen supplements may help improve joint comfort and flexibility, particularly in older adults and active individuals.
Collagen works synergistically with vitamin C, which is essential for collagen synthesis, and magnesium, which supports muscle function and recovery.
Does collagen help with hair and nails?
Collagen provides amino acids (especially proline and glycine) that are essential for keratin, the main protein in hair and nails. Supplementing collagen may help strengthen brittle nails and support healthy hair growth from within.
For extra support, pair collagen with biotin and zinc, which further promote strong, shiny hair and nail resilience.
Marine vs bovine collagen: Which is better?
| Type | Source | Best for | Absorption |
|---|---|---|---|
| Marine collagen (Type I) | Fish skin and scales | Skin, hair, and nails | High - smaller peptides for fast absorption |
| Bovine collagen (Type I & III) | Cow hide | Skin and joint health | Moderate |
| Porcine collagen (Type I & III) | Pig skin | General tissue support | Moderate |
Marine collagen is often preferred in due to its superior absorption rate. However, those with fish or shellfish allergies should avoid marine-based collagen and opt for bovine-sourced options instead.
Choosing the best collagen supplement in Australia
When shopping for collagen, look for:
- Hydrolysed or peptide form (for optimal absorption)
- Type I collagen for skin, hair, and nails
- Type II collagen for joints and cartilage
- Vitamin C inclusion to support collagen synthesis
Vitable’s Marine Collagen is formulated in Australia using sustainably sourced Type I marine collagen.
Vitable’s Marine Collagen
Vitable’s Collagen Plus Hyaluronic Acid and Collagen Creamer is a Type I marine collagen supplement is formulated to:
- Maintain and support skin integrity and structure
- Improve elasticity and hydration
- Reduce the appearance of fine lines and wrinkles
- Support healthy hair and nail growth
How to take collagen for best results
- Take collagen daily for at least 8-12 weeks for visible results.
- Pair with a diet rich in vitamin C (like citrus and capsicum).
- Stay hydrated - collagen synthesis relies on adequate water intake.
- Protect your skin from UV exposure to prevent further collagen loss.
FAQs
Marine Collagen vs Bovine Collagen: Which is better?
Marine and bovine collagen differ mainly by source and collagen type. Bovine collagen (from cows) contains Types I and III to support skin and joints but isn’t suitable for vegetarians. Marine collagen (from fish) offers Type I for skin, hair, and nail health and has faster bioavailability, though unsuitable for those with fish allergies.
2. How long does it take to see results?
Most people notice improved skin hydration within 4–8 weeks, with visible elasticity and firmness by 12 weeks.
3. Is collagen safe during pregnancy or breastfeeding?
Always check with your healthcare provider before taking any supplement during pregnancy or lactation.
Final thoughts: Is collagen worth it?
Yes! Collagen supplementation can be worth it for maintaining youthful skin, healthy joints, and stronger hair and nails, especially as natural production declines with age.
