Would collagen supplementation help an interstitial tear?

Today's episode comes from Olivia who asked a question on the Doc On The Run YouTube channel:    “I believe I'm dealing with an interstitial tear. Would supplementing collagen help the healing process?”   An interstitial tear just means you have little bitty tear on the inside of a tendon or ligament.    You can get these types of injuries in the plantar plate ligament, the plantar fascia, or any tendon. All of those tendons and ligaments are made of collagen.    So, it seems reasonable that collagen supplementation might help the healing process. But is it proven to work?   Would collagen supplementation help an interstitial tear and a runner?    Well, that's what we're talking about today on the Doc On The Run Podcast.
