In recent years, collagen supplements have become one of the most talked-about trends in the wellness world.
Praised for their potential to improve skin elasticity, support joint health, and promote thicker hair. With so many products on the market, and a surge in demand, it’s only natural to ask the question: do collagen supplements really work?
In this blog, we’ll dive into the science behind collagen, how supplements may benefit your skin, joints, and hair, and what to look for when choosing a collagen supplement consumers can trust.
What Is Collagen and Why Does It Matter?
Collagen is the most abundant protein in the human body, making up around 30% of our total protein content. It plays a crucial role in maintaining the structure and strength of skin, bones, muscles, tendons, ligaments, and connective tissue.
As we age, our natural collagen production declines, usually starting in our mid-20s and accelerating through our 40s and beyond. This leads to common signs of ageing, such as sagging skin, fine lines and wrinkles, joint discomfort, and thinning hair.
That’s where collagen supplements come in.
Types of Collagen in Supplements
There are several types of collagen, but Types I, II and III are the most relevant when it comes to supplements:
- Type I: Found in skin, bones, tendons, and ligaments. Ideal for skin health.
- Type II: Supports cartilage and joint health.
- Type III: Often found alongside Type I and important for skin and blood vessels.
Most collagen supplements are hydrolysed (also known as collagen peptides), meaning the collagen is broken down into smaller, easily digestible amino acids.
Collagen for Skin Health
One of the most sought-after benefits of collagen is improved skin appearance. Research has shown that daily collagen supplementation may:
- Improve skin elasticity and hydration
- Reduce the appearance of wrinkles and fine lines
- Support a plumper, more youthful look
A 2019 review published in the Journal of Drugs in Dermatology found that oral collagen peptides significantly improved skin hydration, elasticity, and dermal collagen density over periods ranging from 8 to 12 weeks.
When choosing a collagen supplement for skin health, it’s important to look for hydrolysed collagen (Type I and III), often derived from marine or bovine sources, and ideally paired with Vitamin C, which is essential for collagen synthesis.
Collagen for Joint Support
Collagen also plays a vital role in keeping joints strong and flexible. Type II collagen is especially beneficial for cartilage regeneration and may support joint comfort and mobility, particularly for those with an active lifestyle or age-related joint stiffness.
Several clinical studies have reported that collagen supplements may:
- Reduce joint pain during physical activity
- Improve joint mobility in people with osteoarthritis
- Support long-term joint health and cartilage preservation
Marine collagen and bovine collagen are both widely used, but some formulations may include undenatured Type II collagen specifically for joints.
Collagen for Hair Growth and Strength
Hair is primarily made up of the protein keratin, and while collagen doesn’t directly become keratin, it provides amino acids that support keratin production. Supplementing with collagen may:
- Improve hair thickness and volume
- Support faster hair growth
- Strengthen hair follicles and reduce breakage
Hydrolysed marine collagen, rich in glycine, proline, and hydroxyproline, is often recommended for hair support, especially when combined with nutrients like biotin, zinc, and B vitamins.
What’s the Best Type of Collagen Supplement?
If you’re searching for the best collagen, here are some key features to look for:
- Vitamin C for enhanced absorption and collagen production
- Added nutrients such as hyaluronic acid, biotin, or zinc for extra beauty benefits
- Naturally flavoured, easy-to-mix powders or convenient capsules
- No artificial additives, sugar, or unnecessary fillers
UK consumers are increasingly turning to clean, high-potency collagen formulas that deliver around 5,000–10,000mg of collagen per serving, rivalling premium brands but without the hefty price tag.
Do Collagen Supplements Actually Work?
While results can vary depending on the individual, supplement quality, and consistency, many users report noticeable improvements in skin texture, joint comfort, and hair thickness within 8–12 weeks.
Scientific studies also support these benefits, particularly when high-quality collagen peptides are taken daily and paired with key co-factors like vitamin C.
How to Take Collagen for Best Results
To get the most out of your collagen supplement:
- Take it daily, ideally in the morning on an empty stomach or with a vitamin C-rich drink.
- Stick with it consistently for at least 8–12 weeks.
- Choose a reputable brand that uses hydrolysed collagen and clearly labels its dosage.
If you’re using a powder supplement, consider adding it to water, smoothies, or herbal teas. Some products also come in pre-dosed sachets for convenience on the go.
Final Thoughts: Is Collagen Worth It?
If you're looking for a natural way to support your skin’s radiance, reduce joint aches, and boost hair health, a high-quality collagen supplement customers trust could be well worth adding to your daily routine. When sourced and formulated correctly, collagen peptides have a solid scientific foundation and plenty of anecdotal support.
Whether you’re focused on collagen for skin health, joint recovery, or reversing signs of ageing, consistency and quality are key. And with plenty of options available, it’s easier than ever to find a formula that works for your needs and lifestyle.
