Electrolytes are having a second. When you head to your native grocery retailer or vitamin store, you’ll discover rows of electrolyte-infused powders, tablets, and drinks that declare to rehydrate you rapidly and successfully.
There may be one product, particularly, that many athletes are testing out: salt drugs. The tiny white tablets, which comprise a concentrated quantity of sodium chloride, have exploded in reputation on TikTok, with many individuals swearing the drugs have taken their athletic efficiency to the subsequent degree.
I known as up two sports activities dietitians who work with endurance athletes and requested them what they actually take into consideration salt drugs. They had been in settlement: the common athlete shouldn’t hassle messing with them.
“Most individuals who train don’t want salt drugs; nonetheless, for endurance athletes and individuals who train in scorching environments or at very high-intensity ranges, salt tablets might be helpful,” says Allison Childress, a registered dietitian and affiliate professor within the Division of Dietary Sciences at Texas Tech College.
What’s the Hype with Salt Tablets?
Perspiring throughout vigorous train causes you to lose numerous fluids and electrolytes, together with sodium, potassium, and calcium. When you don’t exchange these misplaced electrolytes, you possibly can change into dehydrated.
With out sufficient fluids in your physique, you possibly can anticipate your muscle perform, athletic efficiency, and cognition to take successful. “You’re finally going to need to decelerate or cease exercising,” says Jena Brown, a sports activities dietitian for endurance athletes and proprietor of the diet teaching service Victorem Efficiency Diet.
When you drink an excessive amount of water or solely drink water, says Childress, throughout extended train—4 hours or extra (for instance, marathons or Ironman distance triathlons), you possibly can wind up with a critical situation known as exercise-induced hyponatremia. This electrolyte imbalance happens when you’ve gotten too-low sodium ranges in your blood as the surplus water dilutes salt focus. This may set off cramping, fatigue, confusion, and low blood stress, in accordance with the Nationwide Kidney Basis.
“Numerous athletes understand salt tablets as a security web that’ll defend them from hyponatremia,” says Childress. The attract is clear: salt drugs, in principle, provide athletes a fast answer after they’re on the go. However can a tiny capsule really hold you quenched throughout and after prolonged exercises?
Figuring Out How Many Salt Tablets to Absorb a Day
Figuring out what number of salt drugs to take—and when to have them—is a fragile dance. Even when, say, you and your buddy are backpacking alongside the identical actual route, the quantity of electrolytes it’s best to ingest could fluctuate, probably considerably, from the quantity your pal requires, Brown says. Your rehydration wants largely rely upon how a lot you sweat (and the way a lot sodium is in your sweat) as a result of some individuals expel extra salt than others.
The one option to know, for certain, how a lot sodium chloride you want after a tricky day on the path is to conduct a sweat take a look at to measure your sweat price and composition. “If an athlete is aware of how a lot sodium they lose, they’ll exchange it to the T,” Childress says.
Sodium focus, or the quantity of sodium in your sweat, varies extensively from individual to individual, says Childress, however, on common, individuals lose about 1 gram or 1,000 milligrams (mg) of sodium per liter of sweat. So, when you sweat out a liter of fluids—and due to this fact about 1,000 mg of sodium—you’d wish to take a salt capsule that has 1,000 mg of sodium throughout (or proper after) your exercise to replenish the misplaced salt, Childress explains.
When you’re in search of a sweat take a look at to find out salt loss, get in contact with a sports activities dietitian. They’ll measure how a lot fluid you lose throughout train and calculate your sweat electrolyte focus. That method, you received’t need to guess what you might want to ingest to remain hydrated. If you wish to work out how a lot sweat you lose, a sweat price take a look at is useful; this entails weighing your self on a toilet scale earlier than and after an intense exercise.

Sure. It Is Potential to Take Too Many Salt Tablets.
Right here’s the difficulty: most individuals wing it. As a result of they’re unlikely to know the way a lot sodium they lose of their sweat, they’ll pop a number of salt drugs, hoping to rehydrate. However taking too many (salt drugs typically are available in a 200- to 400-milligram dose) can wreak havoc in your physique. “The draw back is you possibly can overdose on them fairly simply when you don’t know what you’re doing,” Childress says. When that occurs, you possibly can develop hypernatremia, a situation the place there’s an excessive amount of sodium within the blood, which causes extreme thirst, nausea, confusion, muscle weak point, and dizziness.
Hypernatremia and hyponatremia can appear and feel comparable—so some individuals could develop weak point and assume they’re dehydrated when, in truth, their sodium ranges are method too excessive. Then, they’ll take much more salt drugs and exacerbate the difficulty. In very excessive instances, this could trigger individuals to collapse or have a seizure.
You Don’t Want Salt Tablets—Hydrate This Approach As an alternative
Athletes need to watch out about what number of salt tablets they take, Childress says. Not solely are salt drugs pointless for athletes, however they’re additionally probably harmful.
Nevertheless, when you’re nonetheless set on taking salt drugs, begin with a low dose, says Childress, and be sure to drink sufficient water with them. “You’re not going to have any hydration profit when you’re taking salt drugs and never ingesting fluid. They go collectively,” Brown says.
When you don’t assume salt drugs are well worth the hype, you possibly can skip them altogether. Brown recommends ingesting 16 ounces of fluid per hour that you simply’re figuring out. When you’re a brilliant sweater, it’s possible you’ll wish to up that to (at most) 1 liter per hour, she provides.
A straightforward option to examine your hydration ranges is by evaluating your urine. In case your pee is darkish otherwise you’re going to the toilet much less ceaselessly than traditional, it’s best to improve your fluid consumption. Clear pee suggests you’re over-hydrated and will use some electrolytes, Brown says. The purpose is to your pee to seem like gentle lemonade, she says.
Go for a Salty Snack or a Piece of Fruit
For these exercising at the least three hours or in scorching circumstances, alternate between ingesting water and sports activities drinks to maintain your electrolytes in steadiness, Childress says. It’s also possible to munch on water-rich vegatables and fruits like watermelon, cantaloupe, celery, or broccoli.
To revive your sodium ranges, as an alternative of a salt capsule, throw in one thing extra satisfying, like a bag of pretzels or salted nuts, unfold cheese on a number of crackers, or seize some chips, she says.
When you, like me, don’t hold monitor of your sweat or water consumption, then merely drink to thirst, suggests Childress. Lastly, if you wish to nail your hydration recreation, your greatest wager is to speak to a sports activities dietitian. She explains, “It’s actually well worth the time and cash to fulfill with an expert who can run the sweat checks and design an individualized hydration technique.”
