Vitamin C is needed in collagen production, linking it to tendons and other connective tissues.

Vitamin C supports collagen formation, antioxidant activity and absorption of non-haem iron. Its connective-tissue role includes normal wound healing.
Vitamin C is needed in collagen production, linking it to tendons and other connective tissues.
Follow the sourceVitamin C improves absorption of non-haem iron, the form in plant foods.
Follow the sourcePeppers, kiwifruit and citrus can supply vitamin C. A separate pill is not the only route.
Follow the sourceCorrecting inadequate intake and adding more when already sufficient are different questions. Extra vitamin C is not a proven tendon-repair shortcut.
Large amounts can cause diarrhoea and cramps. Iron overload conditions require particular care.
Follow a relationship.
Look a little closer at the label.
Collagen supplies protein fragments; vitamin C supports the body’s collagen-making enzymes. The relationship concerns making collagen, not collagen boosting vitamin C.
The small gelatin-and-exercise trial did not isolate the added benefit of vitamin C, or demonstrate injured-tendon repair. It does not prove a combined product is better when vitamin C intake is adequate.
This explains a relationship; it is not a check that a combination is safe for you.
Look for the collagen type, animal source and grams of collagen per serving. A scoop’s total weight may include flavouring or other ingredients.
Compare collagen grams, not scoop size.
Use the collagen amount on each label. These starting values are illustrative, not product data or recommended doses.
Mass equivalence only. Different collagen ingredients are not interchangeable, and this is not a number of capsules to take.
The derivative study involved 10 men and found no statistically significant change in the collagen-synthesis marker. It cannot establish that all formats work equally or that an “enhanced” blend works better.
Compare evidence for the exact formulation. Brand age and marketing claims do not earn quality points.
