She may have shot to fame thanks to her roles in films such as Iron Man and Shakespeare in Love, but away from the big screen Gwyneth Paltrow has made a splash in the world of wellness. After setting up her lifestyle brand Goop back in 2008, the health guru hasn’t been afraid of causing controversy when it comes to her alternative routines and products and has popularised many weird and wonderful wellness trends in her time.
