Collagen Supplements: Skin, Joints and Tendons

Collagen is the major structural protein in skin, tendons, ligaments and other connective tissues. Hydrolyzed collagen supplements provide smaller collagen peptides that are easy to mix and digest.
What the evidence suggests
Research suggests potential benefits for skin properties and some joint or tendon outcomes, especially when used consistently. Collagen is low in some essential amino acids and should not be treated as a complete muscle-building protein.
How to use it in practice
Study protocols often use several grams per day, with amounts varying by purpose. Some connective-tissue protocols combine collagen or gelatin with vitamin C before loading exercise, but overall diet and rehabilitation remain important.
What to check on the label
- Check grams of collagen peptides per serving.
- Separate collagen content from added flavoring, sugar or other active ingredients.
- Do not count collagen as your only high-quality protein source for muscle gain.
Safety and context
Choose a source compatible with your dietary restrictions and allergies. People with medical conditions should seek individualized advice.
