Are trending "cortisol cocktails" really helpful for stress and weight loss?

The internet's current obsession with cortisol has prompted a new trending concoction dubbed the "cortisol cocktail" that users claim can reduce stress and even help with weight loss.

Also referred to as an "adrenal cocktail," the drink has some variations across social media but mainly consists of orange or lemon juice, coconut water and a bit of sea salt. 

Experts say there's no evidence this drink can significantly reduce stress or weight by lowering cortisol levels, but the ingredients do offer some nutritional benefits that may give drinkers a boost.
