Collagen is a word we hear often in conversations about health, beauty, and ageing, but how much do we really know about it? From promoting youthful skin to supporting joint health, collagen supplements have gained popularity for their numerous benefits. But are they truly effective, and what does the science say? Let’s dive into everything you need to know about collagen supplements, how they work, and whether they’re worth including in your routine.
Collagen is the most abundant protein in the human body, playing a critical role in providing structure to skin, bones, joints, and connective tissues. Think of collagen as the glue that holds everything together. It’s naturally produced by the body, but production slows down as we age, leading to wrinkles, joint pain, and other signs of ageing.
Collagen is essential for maintaining the integrity of our skin, bones, and overall structure. It keeps skin firm and elastic, strengthens bones, promotes joint mobility, and even supports gut and heart health. Without collagen, our body would lose its youthful resilience.
Collagen supplements work by providing hydrolysed collagen peptides, which are broken-down forms of collagen that are easier for the body to absorb. Once ingested, these peptides stimulate the body’s collagen production and provide the building blocks for repairing and maintaining tissues.
Research suggests that collagen supplements can help improve skin elasticity, reduce wrinkles, alleviate joint pain, and prevent premature ageing. However, their effectiveness depends on consistency and the type of collagen used.

Not all collagen is created equal. Different types of collagen serve different purposes, and knowing which ones to take can maximise the benefits.
The most abundant type, Type I, is primarily found in skin, bones, and connective tissue. It’s excellent for improving skin elasticity and reducing wrinkles.
Type II is a key component of cartilage and is particularly beneficial for joint health and mobility.
This type supports skin, muscles, and blood vessels. It works well in combination with Type I for enhancing skin health.
Type V supports cellular membranes and plays a role in maintaining healthy hair and skin.
Type X is found in cartilage and bones, making it ideal for bone strength and repair.
The best type of collagen for you depends on your individual needs and goals. If you're looking to improve skin elasticity, hydration, and overall appearance, Type I and Type III collagen are the most effective, as they are the primary types found in skin, hair, and nails. For those seeking relief from joint discomfort or wishing to support cartilage health, Type II collagen is your best option, as it specifically targets joint and connective tissue. Many collagen supplements on the market combine multiple collagen types to offer a broader range of benefits, including support for skin, joints, bones, and overall vitality. Choosing the right collagen supplement can help you target specific areas of health while also promoting general well-being.
As we age, collagen production naturally decreases. This decline begins as early as our mid-20s and accelerates over time. The result? Wrinkles, sagging skin, joint pain, and weaker bones. Collagen supplements can help counteract these effects by replenishing the body’s collagen stores.
Choosing between collagen powder and capsules depends on your lifestyle. Powders provide higher doses (10-20g per serving), are versatile for mixing into drinks, and cost-effective but require preparation. Capsules are convenient, portable, and pre-measured, but typically offer lower doses (1-3g per serving) and can be more expensive per gram. For noticeable results like improved skin or joint health, powders are often more effective, while capsules are ideal for simplicity. Both work best with a healthy diet and proper hydration.
Collagen supplements offer a wide range of benefits, making them a popular choice for both health and beauty enthusiasts.
Collagen enhances skin elasticity, reducing wrinkles and promoting a youthful glow. It also boosts skin hydration, reducing dryness.
By replenishing collagen levels, these supplements smooth out fine lines and wrinkles over time.
Collagen aids cartilage repair, reducing joint pain and improving mobility.
It strengthens hair and nails, reducing breakage and encouraging growth.
Collagen plays a vital role in bone density, reducing the risk of fractures.
Collagen supports muscle recovery and maintains muscle mass, especially as we age.
By strengthening the gut lining, collagen can alleviate symptoms of digestive issues.
Collagen helps maintain the elasticity of blood vessels, supporting cardiovascular health.
Collagen improves skin texture, reducing the appearance of cellulite.
It accelerates tissue repair, aiding in faster wound healing.
In addition to supplements, you can boost collagen levels through your diet by incorporating these collagen-rich foods:
Bone broth is a collagen powerhouse, made by simmering animal bones and connective tissues for hours. This slow-cooking process extracts collagen, gelatin, and key nutrients, making it an excellent addition to your diet for supporting joint health, skin elasticity, and overall wellness. Sip it as a warm drink or use it as a base for soups and stews.
Chicken is a fantastic source of collagen, especially in its skin and connective tissues. This makes chicken a staple for those looking to boost their collagen intake naturally. Whether you’re enjoying grilled chicken, roasted thighs, or a hearty chicken soup, you’re nourishing your body with the building blocks for healthy skin, hair, and joints.

Fish and shellfish are rich in Type I collagen, which plays a key role in maintaining the health of your skin, bones, and tendons. Fish skin, in particular, contains high levels of collagen. Incorporating fish like salmon, cod, or shellfish into your meals is a delicious way to promote collagen production.
Egg whites are a hidden gem when it comes to collagen production, as they are rich in proline, an amino acid essential for collagen synthesis. Whether scrambled, boiled, or used in recipes, eggs are a versatile and affordable way to support your body’s natural collagen-building processes.
Citrus fruits like oranges, lemons, limes, and grapefruits are loaded with vitamin C, a critical nutrient for collagen production. Vitamin C helps the body convert amino acids into collagen while also protecting existing collagen from damage. A daily dose of citrus is an easy way to keep your skin glowing and your joints strong.
Berries such as strawberries, blueberries, and raspberries are packed with antioxidants that help protect collagen from free radical damage. They also contain vitamin C, which supports collagen synthesis. Incorporate berries into your diet through smoothies, salads, or as a snack for a collagen-boosting treat.
Garlic is more than just a flavor enhancer—it’s a source of sulfur, an essential mineral that helps your body produce collagen. It also contains compounds that may slow the breakdown of collagen, keeping your skin and joints healthier for longer. Add garlic to your cooking to give your meals a collagen-friendly boost.
Leafy greens like spinach, kale, and Swiss chard are loaded with nutrients that promote collagen production. They contain vitamin C, chlorophyll, and antioxidants, all of which support skin health and overall vitality. Add greens to smoothies, salads, or stir-fries to nourish your body inside and out.
Tomatoes are a great source of lycopene, a powerful antioxidant that helps protect collagen from breaking down due to free radical damage. Cooked tomatoes, like those found in sauces and soups, offer even higher levels of lycopene, making them a delicious way to support your skin’s integrity.
Nuts and seeds, such as almonds, cashews, sunflower seeds, and pumpkin seeds, are packed with zinc and copper, two minerals essential for collagen formation. Snack on them raw, toss them into salads, or use them as toppings for yogurt or oatmeal to easily incorporate these collagen-boosting nutrients into your diet.
While collagen supplements are generally safe, some people may experience mild side effects, such as bloating or a bad aftertaste. It’s also important to ensure supplements are sourced sustainably and free of additives.
The recommended daily dosage of collagen varies depending on your goals, but most studies suggest 5-10 grams of collagen peptides per day for optimal results. Always consult a healthcare professional before starting any new supplement.
