Collagen supplements are marketed for skin, hair and joints. Here we focus on joints: does the research support taking collagen for comfort and mobility?
What the research says
Some randomized trials of hydrolyzed collagen and of type-II collagen have reported modest improvements in joint discomfort, including in people with osteoarthritis and in active adults. The overall evidence is mixed-to-moderate, and results vary by formulation.
Types and dosage
Hydrolyzed collagen (collagen peptides) is the most studied for general joint support, often around 10 g per day. Undenatured type-II collagen is used at much smaller doses. Consistency over weeks matters more than any single serving.
Hydrolyzed Collagen Peptides (e.g. Vital Proteins, Sports Research)
- Hydrolyzed peptides mix easily into coffee, tea or water
- Joint studies often use around 10 g per day, taken consistently
- Look for third-party testing such as NSF or Informed Sport

Collagen is generally well tolerated. It is derived from animal sources, so it is not suitable for vegans. As always, check with your healthcare provider if you are pregnant, nursing or managing a health condition.
