Pickle Juice: Why Athletes Swear By It - And Why You've Probably Been Pouring Liquid Gold Down the Drain

When tennis stars Carlos Alcaraz and Frances Tiafoe have battled cramping during Grand Slam matches, pickle juice has repeatedly come up as part of the conversation around how top players try to manage it. According to EatingWell's reporting, Tiafoe and other professional athletes — including players in the Philadelphia Eagles organization — have been known to take shots of pickle juice specifically to lower their risk of cramping during competition. It's not a fringe habit limited to amateur gym-goers; it's a ritual you'll find in professional locker rooms, too.

That's the hook that makes pickle juice interesting. The part that makes it useful is what's actually in the jar.

What's Really Going On Here?

Pickled cucumbers, and the brine they sit in, come with a genuinely interesting nutritional profile. Yes, pickle juice is high in sodium — a typical serving can carry several hundred milligrams — but the vinegar base it's built on also contributes minerals and trace compounds you don't get from plain water. In some respects, the surrounding liquid can end up carrying meaningfully different levels of certain minerals than the cucumbers themselves.

Many endurance athletes, particularly cyclists and long-distance runners, are painfully familiar with exercise-associated muscle cramps. Rather than turning to expensive supplements, plenty of them reach for a small dose of pickle juice instead. Interestingly, research suggests the relief doesn't come from electrolytes at all. According to a breakdown from ScienceInsights, the effect appears to kick in far too quickly — often within about 60 to 90 seconds — for sodium to have even entered the bloodstream. The leading theory is that acetic acid in the vinegar triggers a nerve reflex in the mouth and throat, sometimes called an "oropharyngeal reflex," which seems to calm the overactive nerve signals behind the cramp itself.

Research covered by PEZ Cycling News found that a small amount of pickle juice relieved an induced cramp roughly 37% faster than plain water, and 45% faster than taking in no fluid at all. That doesn't mean cramps vanish instantly — most people describe the sensation easing rather than disappearing outright — but for someone mid-race with no good alternative, a faster easing of symptoms can matter a lot.

It's worth being clear-eyed about the limits here, though. As sports medicine physician Dr. Jeanne Doperak told TIME, pickle juice has "been a very established urban legend for years," with only limited scientific backing — and it isn't a one-size-fits-all fix. If a cramp is caused by genuine dehydration, she notes, proper fluid or electrolyte replacement is still the better remedy; pickle juice tends to help more with cramps driven by muscle fatigue.

Can It Actually Help With Hydration?

This is where it's important to separate folk wisdom from what's been tested. Some sources suggest that sipping a small amount of pickle brine — around 50 to 60 ml, roughly an hour before a workout — may support the body's fluid balance thanks to its sodium content, which can help the body hold onto water rather than lose it. That said, more rigorous testing tells a more modest story: some research reviewed by ScienceInsights found that drinking pickle juice while dehydrated produced very little measurable change in blood plasma volume over the following hour, largely because the volume people typically drink is simply too small to meaningfully rehydrate the body on its own.

So it's best to think of pickle juice as a small, situational tool rather than a hydration strategy on its own — a useful sidekick to drinking enough water, not a replacement for it. If you're prone to cramping during long or intense exercise, talk to a coach, trainer, or healthcare provider about what a sensible hydration and electrolyte plan looks like for you specifically.

The Morning-After Myth (And the Grain of Truth In It)

You'll also find plenty of people reaching for pickle juice after a heavy night out, on the theory that it helps with rough mornings. There's a reasonable explanation behind the idea: alcohol is a diuretic, and it can flush out sodium and other electrolytes along with fluid. Pickle brine happens to be rich in exactly those minerals, which is probably why the habit persists. That said, this use case hasn't been studied nearly as rigorously as the muscle-cramp research, so it's best treated as an anecdotal remedy rather than a proven one — and it's not a substitute for drinking plenty of water and giving your body time to recover.

Hiccups and PMS: Where the Evidence Gets Thinner

Pickle brine also shows up frequently in home-remedy lists for hiccups, and for easing some of the discomfort associated with the menstrual cycle. The proposed mechanism is similar to the cramp story — the sharp, sour taste and the acetic acid may stimulate nerve pathways that interrupt the hiccup reflex, and the sodium and trace minerals may offer some comfort during PMS the same way other salty or mineral-rich foods sometimes do. These uses are much more anecdotal than clinically proven, though, so they're best treated as a low-risk home remedy to try rather than a guaranteed fix — and if cramping, hiccups, or PMS symptoms are severe or persistent, it's worth checking in with a doctor rather than relying on brine alone.

The Bottom Line

Pickled cucumbers — and the brine they're sitting in — are more nutritionally interesting than most people give them credit for. The next time you finish a jar, it might be worth pausing before you tip that brine down the drain. A small sip before a workout, or when a cramp strikes, is a low-cost, low-risk experiment that plenty of elite athletes already swear by. Just don't expect it to replace water, real electrolyte replacement, or a conversation with a doctor if cramps, dehydration, or PMS symptoms are a recurring, serious problem for you.
