Can collagen support healthy joints and strong bones?

Have you ever wondered what keeps your skin firm, hair strong and joints moving comfortably? The answer lies in collagen – a protein that plays a crucial role in maintaining the health of your skin, hair, nails, joints and bones. Think of it as the scaffolding that holds everything together, providing strength and structure.^1,2

Collagen is the most abundant protein in your body, making up around 30% of your total protein content.¹ It’s a key building block of connective tissues, including tendons, ligaments, cartilage and bones.² As collagen levels naturally decline with age, the structures that support your joints and bones can start to feel the effects.^3-5

Your bones rely on collagen too. It acts as the framework that minerals like calcium attach to, giving bones their strength and structure.^7,8 When collagen production decreases, this framework can weaken, which may contribute to bone loss over time.^9,10 The European Food Safety Authority (EFSA) states that there’s not enough evidence to make official health claims about collagen supplements’ role in joint and bone health.¹¹ However, emerging research suggests collagen may play a supportive role, particularly alongside an active lifestyle and exercise.

Some research also suggests that after absorption, collagen peptides may build-up in cartilage and could play a role in supporting the body’s natural collagen production.¹³ Other studies suggest collagen supplements may help support joint function and reduce discomfort during activities like walking or climbing stairs.^7,14

There are different types of collagen in your body, each with its own role. Type II collagen is particularly important for joints as it’s a primary component of cartilage.¹³ Undenatured type II collagen supplements, for example, often come from chicken cartilage. Unlike collagen peptides, this type of collagen keeps its natural structure rather than being broken down into smaller pieces, meaning it works differently in the body.^13,24 It’s worth noting that the collagen your body produces isn’t exactly the same as the collagen found in supplements, and more research is needed to fully understand how they compare and what effects they have.

Type I collagen is the most abundant form in the body and is closely linked to bone health. It plays a key role in giving bones their structure and strength, helps form the dense fibres that support them and contributes to the body’s natural bone repair processes.^25-27

Collagen plays an important role in supporting your joints and bones, particularly as you age or increase your activity levels. While research into collagen supplements is still developing, they may offer a convenient way to support your routine. If you’re considering collagen, look for high-quality options that fit easily into your day – whether that’s powders, drinks, capsules or even creams. As always, a balanced diet, regular movement and good lifestyle habits remain the foundation of joint and bone health – with collagen as a potential addition to support your goals.
