Bone broth is hyped by celebrities and hailed as a wellness superfood – here’s what the science says

When someone tells you to “clean your plate”, bones usually aren’t included. But for some people, bones – or rather, what’s inside them – are the best part of a meal. Bone broth, once a humble kitchen staple, has surged in popularity in recent years, championed as a superfood by celebrities and wellness influencers.
Stars such as Salma Hayek and Gwyneth Paltrow are reported to swear by it for beauty and health, while late basketball legend Kobe Bryant used it as a pre-game meal.

So, what exactly is bone broth – and does it live up to the hype?
