Social media influencers are promoting a so-called 'cortisol cocktail' that they claim can lower levels of the stress hormone cortisol. The drink, which combines coconut water, lemon, orange juice, sea salt, sparkling water and magnesium powder, has gone viral on platforms like TikTok and Instagram.
However, doctors have warned that while the ingredients may support relaxation and hydration, there is little scientific evidence to suggest the drink can significantly reduce cortisol levels. Dr Charles Carlsen, an OBGYN and chief technology officer at DRSONO Medical, told DailyMail.com: 'There is not a lot of scientific evidence to support arguments that a given drink lowers stress hormones significantly.'
Cortisol is a hormone produced by the adrenal glands that regulates metabolism, blood sugar, blood pressure, inflammation and sleep. Chronically high levels can lead to weight gain, heart disease, high cholesterol and infertility. But experts say the cocktail is unlikely to be a cure-all.
Dr Jeffrey Ditzell, a psychiatrist in New York City, added: 'There is likely more hype than help with cortisol cocktails.' The doctors recommended proven stress-reduction strategies such as regular exercise and a balanced diet instead.
They also cautioned against consuming multiple cortisol cocktails daily due to the risk of magnesium toxicity, which can cause diarrhoea and stomach discomfort. Dr Daniel Atkinson, clinical lead at Treated, noted that raising magnesium levels through supplements is not instantaneous and that dietary sources like whole grains, legumes and nuts are more effective.
