Collagen supplementation can be more meaningful for specific target groups: individuals noticing reduced skin elasticity, those with high UV exposure, athletes seeking connective tissue support, people with joint discomfort or cartilage sensitivity, and older adults. It may also be considered to support skin recovery after significant weight loss. The key is choosing the right collagen type for the goal: hydrolyzed Type 1–3 for skin-focused outcomes, and Type 2 (often UC-II) for joint-focused support. If you are pregnant, breastfeeding, have serious chronic illness, use long-term medications, or have allergy history, proceed with clinician guidance. Collagen is not “for everyone,” but its cost-benefit profile improves when matched to the right user profile and objective.
