Collagen supplements promise smooth skin, but you should eat these foods instead - Cnet

Collagen might be the fountain of youth, but you don't need it in pill form.

If you've been paying attention to the internet lately, you've probably noticed a trend popping up: collagen supplements. Collagen is marketed as the "fountain of youth" and you can buy it in pill, powder, liquid and gummy form. There's even a host of dermatological treatments, like the vampire facial made famous by Kim Kardashian, promising to promote collagen formation.

Collagen supplements and elaborate skincare treatments promise a host of benefits, including giving you better skin and nails, improving your gut health, promoting joint health and making you stronger. But do they really work? And what even is collagen, anyway? I did some research and talked to registered dietitian and nutritionist Tony Castillo to discover the answers to all of my questions.
