Gwyneth Paltrow has revealed she's still suffering the after-effects of COVID-19, despite having caught the virus "early on".
The Shakespeare in Love star said she's dealing with several worrying symptoms including "long-term fatigue and brain fog".
"I had some tests done that showed really high levels of inflammation in my body," she added.
The 48-year-old actress wrote a blog on her website Goop discussing all the various 'alternative treatments' she's put in place to try to combat the health issues like infrared saunas, supplements and fasting.
"I fast until 11am every day," she explained, adding that she's cut out sugar and alcohol completely.
Paltrow said that cleaning up her "thought patterns" alongside her exercise and diet regimes had left her feeling "energised and healthier", even while coping with being a COVID-19 long-hauler.
Newshub was unable to find any evidence that Paltrow's methods have been scientifically proven to help ease the symptoms she mentioned.
"Moving your body and sweating out toxins makes an enormous difference, of course," she wrote.
"When I go for a hike, I know I'm getting something different - stimulating my brain and body in ways I can’t get otherwise. Nature heals, really!"
"Everything I'm doing feels good, like a gift to my body. I have energy."
Paltrow's lifestyle and wellness brand Goop has been frequently criticised for promoting questionable and sometimes dangerous practices lacking in scientific backing.
In 2017, Goop was hit with a US$145,000 fine for making unsubstantiated claims about a 'jade egg' that could supposedly improve orgasms and hormone imbalances when inserted into the vagina. Experts were quick to warn consumers of the risks the eggs carried.
Paltrow has also promoted bee venom therapy, vaginal steaming and pricey 'healing stickers' that falsely claimed to be made of the same material NASA uses in space suits.
