Collagen supplements: an update on the evidence for health benefits

Thinking Nutrition

It was back in episode 55 that I first tackled the topic of collagen supplements. It proved to be one of my most popular episodes ever. And for good reason as there is a growing evidence base to support many of the health claims made about collagen: from improving skin health to perhaps even helping with sports injury recovery and osteoarthritis. In this podcast, I give an update on the growing scientific evidence for the use of collagen supplements. I’ll also explain how there is certainly a plausible biological mechanism to explain how this particular dietary protein source can have a targeted benefit even after digestion.
