Why do athletes take pickle juice?

It might not be your tipple of choice. But for many athletes, pickle juice has become a staple.

Carlos Alcaraz and Jannik Sinner were both seen sipping what was thought to be pickle juice during their five-set thriller of a French Open final.

But seeing athletes swigging the salty stuff isn’t anything new.

Former Arsenal midfielder Lucas Torreira was pictured drinking from a bottle labelled “pickle juice” back in 2019, and it became part of the England team’s strategy to combat cramp in players at Euro 2024.

Pickle juice is used by athletes as a means of easing muscle cramps.

The acidic liquid is a concentrated source of electrolytes, containing sodium and potassium. It has been found to stop cramping 40% faster than drinking water.

It is thought that pickle juice works by disrupting ‘neural signalling’ – triggering a reflex in the mouth which sends a signal to stop muscles from cramping.

Mayur Ranchordas – a professor of sports nutrition and exercise at Sheffield Hallam University – believes there is still a misconception that pickle juice can be used to prevent muscle cramps.

There is no evidence to suggest that drinking the juice before a sports event would have any benefit.

Instead, athletes should be taking it at the onset of cramp – but not drink it.

“Rather than drinking it, you need to rinse it in your mouth for 20 to 30 seconds. That’s when the vinegar and salt start to act, then you can spit it out”, Ranchordas told BBC Sport.

The mistake that some athletes make is to rinse their mouth out with water, to get rid of the taste.

Removing that sensation – of taking pickle juice and wanting to scrunch up your mouth in response – stops the mechanisms firing which ease the cramp.

Ranchordas, who is also the head of nutrition at Aston Villa football club, says that adding chilli to the jar of pickles, and letting the chilli infuse, can make the pickle juice even more effective.

The more palatable option – for the non-pickle-lovers out there – might be a sweet sports drink.

But the unique offering of pickle juice that it can disrupt the message sent to the brain that a muscle is cramping.

This is a much faster method of easing cramping than having an electrolyte, which you have to digest and absorb.

But Emma Tester – a performance nutritionist currently working at the UK Sports Institute – told BBC Sport that more research is needed to understand the added benefits of pickle juice.

Not quite. Pickle juice is thought to be effective because of the concentration of electrolytes, combined with the fluid.

Pickle juice might not sit well with everyone, potentially causing digestive issues because it is so concentrated and salty.

Dr Tester says she has seen athletes “puke on the side of the pitch” after taking pickle juice, which can hinder performance rather than help it.
