Gwyneth Paltry's Goop company has had a lot of controversial claims/products - from Wiki:
In January 2015, Paltrow advocated for a spa treatment referred to as vaginal steaming,
In October 2015, in a blog post in Goop, Habib Sadeghi revisited the disproven claim that breast cancer might be linked to wearing underwire bras.
In January 2017, Goop marketed the "Jade Egg" for $66 USD as a form of vaginal weightlifting which, according to their website, is "used by women to increase sexual energy, health, and pleasure."[
In 2017, Goop promoted a coffee enema device from Implant O’Rama LLC, despite a lack of scientific evidence to their efficacy and in spite of evidence of coffee enemas' potentially fatal side effects.
In January 2018, Goop was criticized for posting articles by "medical medium" Anthony William who claims to use paranormal abilities to give advice.
In October 2018, the Good Thinking Society reported the company to the National Trading Standards and the Advertising Standards Authority, claiming that Goop has breached over 113 advertising laws of the UK. .....
It is shocking to see the sheer volume of unproven claims made by Gwyneth Paltrow’s Goop about their products, especially given that some of their health advice is potentially dangerous... Gwyneth Paltrow may well have good intentions, but she and her company sell products with claims that could clearly mislead customers... if Gwyneth Paltrow cannot provide satisfactory evidence behind the claims she makes for her products, she should not be making those claims.
