Collagen supplements: legit or Insta influencer fairy dust?

Thinking Nutrition

Collagen supplements are big business. And is it any wonder when they are touted as the elixir for youthful and glowing skin. With plenty of A-list celebrities singing its praises, it’s no wonder collagen is having a moment in the spotlight. And a look at Google Trends shows search interest in collagen supplements really took off at the start of 2019 and it is showing no signs of slowing down. Reading the shopping list of health claims made about collagen - from turning back the clock on your skin, treating joint pain and even ‘healing your gut’ - you should rightly raise your sceptical flag. Yet when you look at the scientific evidence, there could just be some validity to some of these claims. That’s what I’ll be exploring in this podcast.
