Skin & tissue structure
Collagen forms part of the skin’s supporting framework and helps give connective tissues strength.
Understand your body. Make informed choices.
Collagen helps give your body structure. Discover why it matters, how to support it and what supplements can—and can’t—promise.
Get to know collagenWhy collagen matters
Collagen’s natural role in your body is well established. That does not mean taking extra collagen guarantees the same benefits.
Collagen forms part of the skin’s supporting framework and helps give connective tissues strength.
It is found in cartilage, tendons and ligaments—tissues that help support joints and connect parts of the body.
Collagen contributes to the bone’s protein framework and plays a role in normal tissue repair.
Collagen production naturally changes with age. Sun exposure and smoking can also damage collagen.
A closer look at supplements
Collagen powders, capsules and drinks are often marketed for skin and joint health. Research is still developing, and findings are mixed.
“Hydrolyzed collagen” or “collagen peptides” means collagen broken into smaller pieces. Taking it does not send it directly to a particular body part.
Some studies report improvements, but study quality varies and more independent research is needed. Supplements are not a proven way to reverse aging.
Some trials suggest a benefit for joint discomfort. Collagen does not replace assessment or treatment for persistent pain or arthritis.
Evidence is limited. Claims of guaranteed hair growth or stronger nails go beyond what current research can reliably establish.
Support the basics
A varied diet and everyday skin protection are practical places to start.
Beans, lentils, tofu, eggs, dairy, fish and meat provide amino acids your body uses to make proteins.
Vitamin C supports normal collagen formation. Citrus fruit, berries and peppers can contribute to your intake.
Use sun protection, seek shade and avoid smoking to reduce avoidable damage to skin and collagen.
A balanced diet provides supporting nutrients. A collagen supplement is not a substitute for varied meals.
Common questions
Not everyone needs one. Your body makes collagen from dietary nutrients, and many people can get what they need from a balanced diet. A clinician can help assess your individual needs.
Most collagen supplements are animal-derived. Plant-based “collagen boosters” usually contain nutrients intended to support your own collagen production, rather than collagen itself. Check the ingredient list.
There is no guaranteed timeline or outcome. Studies use different products and durations, so marketing promises of results in a fixed number of days should be treated cautiously.
Digestive discomfort and allergic reactions are possible. Review ingredients carefully, especially if you have a fish or other food allergy. Stop using a product and seek medical advice if you develop a reaction.
