Collagen is a protein that gives structure to skin, tendons and cartilage. Collagen supplements are popular, but the evidence is limited. For skin there are small studies with mild improvements in moisture and elasticity, and for joints the picture is mixed.
What helps more than a supplement
- Use sun protection every day, because it is better supported than supplements for keeping skin healthy.
- Do not smoke.
- Eat enough protein: fish, eggs, pulses, dairy.
- Eat fruit and vegetables rich in vitamin C, which takes part in making collagen in the body.
- For joints, exercise moderately and keep a healthy weight.
If you still choose a supplement
If you choose a supplement with marine collagen, check that it comes from fish, especially if you are allergic to fish or seafood. Read the amount per serving, the list of added vitamins and the instructions. Judge it after several weeks and do not expect a miracle. The quality of supplements varies a lot.
Joint pain that lasts, swelling or stiffness is a reason to see a doctor. A supplement does not replace treatment.
Forever Marine Collagen is available as a supplement with marine collagen, checking the fish origin, ingredients and amount per serving.
How to judge the effect
- Before you start, note the state of your skin or joints, for example with a photo in the same light.
- After eight to twelve weeks, compare with the starting point.
- If there is no visible difference, do not raise the amount; stop and invest in sun protection and diet.
Have health symptoms assessed by a clinician and follow the agreed treatment plan.
